Dear readers,
APRIL 2016
Hope you are happy with our first magazine edition. We
have got good feedback from all of you. Thanks for your co-operation
and support.
Whatever you are deep inside yourself reflects itself loudly and
clearly through your behaviour. Our thoughts and emotions behind
our behaviour leave their imprints on our face as a record of our past
history. You are on the outside as you think inside. You sculpture
yourself by your dominant thoughts. The expression of your face,
the impression of your behaviour are the result of how you have
conceived yourself to be.
Thus what you are today is the result of your yesterdays. What you
will be tomorrow depends on how you chisel yourself from now on.
No one is the finished product. We are in the continuous process of
sculpturing ourselves into newer and newer form. Only the quality
of form depends upon the way we recreate ourselves, the way we chisel
ourselves. You should rather concentrate upon becoming rather than
on possessing; not on how you can have more, but how you can be
more- more loving, more courageous, more joyous, more friendly,
more forgiving, more humble, more patient, more helpful.
You become a greater human being by striving to identify yourself
with the best in you, by giving courageous expression to your ideals
and values, to your gifts and talents.

Scientists just made the world's smallest diode out of DNA.
Researchers have shrunk down one of
the fundamental components of
modern electronics, creating the
world's smallest diode out of a single
molecule of DNA. In fact, it's so tiny,
you can't even see it using a
conventional microscope.
Diodes are electronic devices that
make it easy for current to flow in one
direction, but not another. In other
words, they're responsible for moving
current around a lot of common
electronics, and are printed by the
millions onto modern-day silicon chips.
But to increase the processing power of
these chips, we need to make diodes a
lot smaller, which is where DNA comes
into it.
When thinking about designing smaller
diodes and electronics, researchers
have long been focussing on using
single molecules, since they're the
smallest stable structure imaginable.
But what they weren't sure of was
whether it could control the flow of
electric current, like a diode needs to.
To be clear, no diode is perfectly
efficient - in a perfect world, a diode
would block 100 percent of current in
one direction, and would allow infinite
current flow in the other.
But in reality, today's diodes still let a
tiny current pass back and forth each
direction. Overall, what defines diode is
that there's an imbalance in how they
transmit current, and the bigger that
imbalance, the better.
To get DNA to do this, the team took a
single strand that was just 11 base pairs
AGNOSCO
long (pretty tiny when you consider
inside every cell of our bodies we have
DNA strands with approximately 3
billion base pairs all curled up). They
then added a molecule called
coralyne into the helix structure, and
connected the whole thing to a tiny
electronic
circuit
only
a
few
nanometeres long.
Surprisingly, the DNA turned out to be a
pretty good diode, with the current
flowing through the molecule 15 times
greater for negative voltages than for
positive ones.
"This finding is quite counterintuitive
because the molecular structure is still
seemingly symmetrical after coralyne
intercalation".
Although
the
DNA
diode
was
impressive, it wasn't quite as efficient as
other single. But this one is a whole lot
smaller than anything else out there,
which means that you can pack more
of them onto a chip and potentially
create smaller and more powerful
devices.
The team is now looking into how they
can further improve the efficiency of
the DNA diodes to get them to one day
compete with silicon diodes. And the
possibilities are pretty exciting - just
imagine finally being able to have
functional electronics built on the
molecular scale. The future is looking
bright.
The research has been published
in Nature Chemistry.

The sound of your skull could soon replace your password
more secure than "123456".
Biometric security is taking over
from the humble password, from the
fingerprint sensor you might use to
unlock your phone, to advanced iris
scanning - and now there's a new
method in the pipeline: the sound of
your skull.
Eventually, the required tech could be
incorporated into smartphones, so
holding one to your head to take a call
would be enough to identify you.
The name for the new system is Skull
Conduct, and it joins various other
weird and wonderful biometric security
solutions in development, including
ones using vein and brain waves. The
idea is that these biological markers
are much harder to fake, whereas if
someone steals your password, you're
pretty much out of luck.
Scientists in Germany are working on a
system that can identify the way your
skull vibrates in reaction to an
ultrasonic signal, because it could be
just as unique as your fingerprint. It
could eventually be used to prove you
are who you say you are when logging
into your email, or trying to gain access
to the Pentagon.
Of course, to measure skull vibrations
you're going to need some kind of
headset or accessory, and the
researchers are currently working with
a Google Glass-style device to log you
in.

WiTricity the future of electricity
There is no argument in that we
humans love electricity. We love that
stuff so much that you can get an idea
about it just by walking out on the
street. There is about trillions of money
spent in setting up power stations and
wires carrying electricity from where it
is generated to our homes and offices.
Not only this. We love batteries too! An
object that gives us power for a while
before ending up in the garbage. But
then there is a negative aspect to all
this. Wires and batteries are awful. Just
think about it, overhead wires gets
damaged in rough weathers and can
lead to calamities that can claim a
human life. Plus imagine getting
tangled in one of those wires under your
computer desk. I know it’s pathetic.
MIT Professor Marin Soljačić stood in his
pyjamas looking at his phone. This was
the 6th time in that month that he was
woken up by the beeping of his phone
warning him that the battery was low. In
those moments a thought occurred to
him. “There is electricity wired all
through my house, my office and
everywhere. The phone should take
care of its own charging!” But to make
this dream into a reality, one has to find
a way to transfer power from these
wired infrastructures to the phone
wirelessly. Soljačić started working on a
physical phenomenon that would
make this possible.
Imagine what if there was a technology
through
which we
could
built
something that will never require us to
plug our computers and phones into
plug points ever again. That’s where
wireless electricity (WiTricity) comes
into picture.
In this experiment, one of the coils was
connected to an AC power supply
having a resonant source. The other
coil having a resonant capture device
was connected to a 60W light bulb.
They were suspended in mid-air by a
nylon thread at a distance ranging from
a few centimetres to 2.5 meters. The
power supply was able to light the bulb
wirelessly.
As for the batteries, 40 billion of them
are manufactured every year and
when their work is done, they fall apart
disintegrate and end up in a junkyard
slowly decaying and releasing harmful
stuff into the environment.
The earliest vision of wireless electricity
was thought by Nikola tesla. As great as
an engineer and inventor he was, he
dedicated his whole life to work with
electricity. But his vision of a world
running on wireless electricity was
made possible for the first time by a MIT
professor on his third sleepless night.
AGNOSCO
Soljačić with a group of MIT physicists
was able to power a light bulb of about
60 watt from a distance of two meters
wirelessly. It was around 50% efficient
which is still a thousand times more
efficient than what a battery would be
to perform the same task. The concept
behind it was called the resonant
energy transfer.
So what is resonance?
When two objects vibrate at a same
frequency they are said to be in
resonance. And the frequency at which
they are vibrating is called resonating
frequency. The energy can be
Page 6 of 36
transferred between two resonating
objects at some distances.
Try to understand it like this, inside a
transformer there are two coils of wires.
They are very close to each other and
transfer energy from one coil to another
magnetically and wirelessly. But this
phenomenon occurs over a very short
distance. What dr. Soljačić did was
separate the coils in the transformer to
a greater distance than the size of those
transformers and make it work
somehow.
How WiTricity technology works?
Imagine a coil with a capacitor
attached to it. If we can make this coil
to resonate, what happens is that it will
pulse at a resonating current frequency
which is fairly high. And if a “power
capture coil” is brought close near to
the source such that it will only work at
the same frequency, what happens is
the magnetic field will induce a current
in the capture coil and a magnetic field
around it. The magnetic fields of these
two coils couple tightly and they
transfer power efficiently.
In simple words what’s actually
happening is you convert electricity
into magnetic field and take that
magnetic field and turn it back into
electricity to use it but over some
distance.
power transfer. Whatever the job may
be difficult dirty or dangerous, wireless
power delivers reliable and sustainable
power.
What is the future of WiTricity?
We can look forward for a world in
which wireless power is integrated in all
parts of everyday life. Wireless
electricity is still a very new concept
and in its development phase but it
holds a wide range of applications
where it can be used. The applications
where it has been tested efficiently
ranges from household appliances to
industrial applications. We have been
able to charge cell phones wirelessly
and have been able to turn on our
television sets wirelessly.
Wireless power holds potential for its
uses in hospitals as it can provide a
cleaner
and
more
hygiene
environment. It can be used in
implanted medical devices which will
reduce the infection. Imagine walking
into your room and your desktop
turning on automatically. Or imagine a
wireless home where you place your
lamp anywhere and it lights up or your
phone charging while it’s still in your
pocket. Imagine a world without wires.
The idea is revolutionary!
What are its benefits?
This non-radioactive power transfer
works on magnetic fields and is 100%
safe in nature. It’s almost the same as
the earth’s magnetic field. It reduces
the cost when compared to wired
connectors.
Plus
imagine
how
convenient it would actually be in day
to day life for charging everyday
electronics. It is also a very safe way of

WATLY
These
huge
solar-powered
machines can provide an entire
village's water supply.
For many people living in developing
nations, easy access to clean water is
an ever-present struggle. It's estimated
that 1.2 billion people in the world are
living in areas where uncontaminated
water is scarce, and the equipment
needed for purifying it isn't always
available.
So a team led by Italian entrepreneur
Marco Attisani has come up with a
pretty ingenious solution - a new type of
generator that's capable of using solar
power to bring clean water, electricity,
and even internet access to remote
communities anywhere in the world.
It's called Watly, and a prototype
is already being tested on a village in
Ghana. Its makers have opened up an
Indiegogo campaign to fund an even
bigger machine - one which would be
able to help a community of up to 3,000
people.
system also uses heat from the solar
panels to distill the water, before it's put
through a special mineraliser and acid
reducer to regulate the water's pH
level.
Three 5,000-litre tanks store water inside
Watly.
That would be valuable enough on its
own, but Watly can also recharge
phones, lamps, and laptops, bringing
electricity to remote communities that
can be used for all kinds of purposes.
Watly's makers say it uses a
combination of radio links, existing
3G/4G
networks,
and
satellite
connections to get online - and
separate Watlys can communicate
with each other, too. The lifespan of one
machine is expected to be around 15
years.
India’s long pending problem can be
solved if such devices are installed
……Clean Water….Less Disease!!!
Here's how it works: the modular system
inside Watly harvests energy through
photovoltaic solar panels on its surface,
and then stores it as electricity in its 140
kWh battery. Some of this power is used
to purify and desalinate water from
oceans and rivers. It requires lowmaintenance to run, and works without
a connection to the grid.
For water purification, Watly uses

Nanogenerators: Pocket Powerhouses
The development of an existing
technology is measured is terms of
increase
in
efficiency,
selfsustainability and/or portability. Since
the invention of the light bulb, we have
always strived to find a better way to
power it. First there was direct current,
then alternating current; then the more
portable
sources
like
batteries,
rechargeable batteries, fuel cells and
technologies invoalving the use of
alternative resources of energy (wind,
solar, hydroelectric, etc.) to power
electrical and electronic devices. But in
the field of electronics, size is an
important parameter as devices grow
smaller and smaller every day whilst
providing a greater amount of power
and using lower input energy.
There is energy everywhere around us
in our living environment. It is up to us to
figure out a way to transform this
energy to do some useful work. If we
just look at our body for example, it
consists of neurons constantly firing
electric signals throughout the body to
process response and generate stimuli
(electrical energy), it also consists of
many links and mechanisms which do
work like when we walk our footsteps
generate about 67 Watts of power or
our finger movement produces 0.1
Watts (mechanical energy), chemical
reactions take place to release energy
from our food to maintain our body
temperature
and
metabolism
(chemical and thermal energy). Even
though these sort of outputs cannot
power big electrical devices, if
transformed accurately it can be used
to power small electronic circuits.
Nanogenerators aim to do just that.
AGNOSCO
In this article we will look into the
Nanogenerators from conception to
how they work to what they hold in
store for our future.
Figure 1 Nanogenerator circuit
What Are Nano Generators?
A Nanogenerator is a term used by
scientists to describe a small electronic
chip which transforms mechanical or
thermal energy (produced by minute
physical reaction) into electricity. They
have an IC (integrated circuit) etched
onto an elastic surface, called the
substrate, which is basically the type of
circuits that we would find in the
electronic devices but at a minute
scale as the term “Nano” () implies.
Viewed from the naked eye, it looks
like lines and boxes but, underneath all
that
(when
viewed
through
a
microscope) lies a complex system.
The goal to be achieved by a
Nanogenerator
is
provide
selfsustainability to the Micro/Nano
Systems by harvesting energy from its
environment. It was first proposed by Dr.
Zhong Lin Wang and his colleagues at
Georgia Institute of Technology in 2006
Page 9 of 36
and they had developed the first
Nanogenerator for a self-powered
system.
Mechanical is energy although small, is
available in plenty in various forms in
the environment. It can be light wind,
body motion, muscle stretching, sound
waves, noises, vibrations, blood flow
etc.
To convert the mechanical energy into
electricity nanogenerators use arrays
of “Nanowires” which are made of
piezoelectric zinc oxide (ceramic)
material.
Piezoelectric
materials
produce a potential difference when
they are strained. The strain is provided
by the environment which these
piezoelectric nanowire arrays convert
to electric potential. The straining force
results in a transient flow of electrons in
the external load because of the
“Piezopotential”. The advantage of
using these nanowires is that they can
be triggered by a tiny external force at
wide range of excitation frequencies
(One Hz to thousands of Hz). By
combining the effects of thousands of
such piezoelectric nanowires, a gentle
strain can produce about 1.2V of
electricity which can power an LED and
a small LCD unit.
Nano Materials for Nanogenerators
Among
the
materials
used
in
nanotechnology, ZnO (Zinc Oxide), a
semiconducting ceramic material, is
one of the most common choice as it
has abundant configurations required
from a nanomaterial. It has a wide
range of applications in Optics,
optoelectronics, biomedical science,
sensors,
actuators,
energy
and
spintronics. Under normal conditions, it
has a Wurtzite structure which is a type
of hexagonal crystal system. Its
structure is the main reason why it is a
AGNOSCO
widely used semiconductor. Although
the whole unit cell is neutral, the lack of
symmetry in the cell (a tetragonal
structure within the HCP (Hexagonal
Closely Packed) configuration, some of
the surfaces of the material are
terminated with a larger concentration
of free charges. These polar charge
surfaces give rise to some unique
growth phenomena. The nanowires are
mostly grown in hexagonal rod like or
belt like shapes. Some of the common
methods to produce nanowires are
1) Vapor-Solid-Solid (VSS) process;
2) Vapor-Liquid-Solid (VLS) process;
3) Pulsed Laser Deposition (PLD);
4) Chemical Approach.
These processes produce nanowires in
shapes of rods and belts depending on
the various specifications needed.
Each nanowire measures around 100 to
300 nm in thickness (0.0000001 to
0.0000003 meters!) and lengths of
about 100 microns which is equal to
100,000nm (which is roughly equal to
the width of two human hairs). Besides
ZnO nanowires, other wurtzite structures
like CdS, GaN and InN are being used
for electricity generation. Out of these,
GaN and InN are quite encouraging as
they can produce an output voltage of
about 1V per nanowire.

ONLINE TRANSFORMER MONITORING
Madhu Ningareddy IvSEM
INTRODUCTION:
To safeguard and continuously
improve the operational quality of
electrical
distribution
networks,
power customers are increasing
their efforts to monitor every device
on the distribution network. As a
critical component of any smartgrid
deployment,
substation
monitoring is key to these efforts.
In order to observe the Power
consumption status of distribution
end-use sectors, power utilities hope
to obtain real-time monitoring data
from substations. This data is vital for
analyzing the operational status of
end-users and to detect potential
problems, which may shorten
outage duration, thus improving the
power supply quality.

Dr Kalam is called the missile man of
India. Tessy Thomas was associate
project director for the three
thousand kilometer range Agni 3
project. Agni-III is an intermediaterange ballistic missile developed by
India as the successor to Agni-II and
is capable of engaging targets
deep inside neighbouring countries.
The missile's Circular error probable
(CEP) is within 40 meters range,
which
makes
it
the
most
sophisticated and accurate ballistic
missile of its range class in the world.
She was project director for the Agni
4 project that was successfully
tested in 2011. Agni-IV is the fourth in
the Agni series of missiles which was
earlier known as Agni II prime.
When photographs of jubilant

Development Organisation(DRDO)
scientists appeared after the may 7
launch of Agni III, Tessy was the
subject of many a question. But the
53 year old associate project
director of Agni missiles takes the
curiosity in her stride. What matters is
that her gender is not called into
question at her workplace. ’Here, I

am considered as a scientist and
not a woman. But it has to be taken
into account that the job with DRDO
comes with a responsibility; it is for
one who can understand the
criticality of the work,’ the woman
from Alleppey in Kerala said. ’It was
the determination of my mother
that kept me going. My M.Tech
degree in guided Missiles gave me
an upper hand. Also I joined under
Dr. A.P.J .Kalam and have worked
under
seniors
who
always
encouraged
me’.
Former
Prime
Minister
Manmohan Singh told to the Indian
Science Congress that Mrs Thomas is
an example of a "woman making
her mark in a traditionally male
bastion and decisively breaking the
glass ceiling". Tessy Thomas was
conferred the Y. Nayudamma
Memorial Award in the year 2014
and She was awarded Lal Bahadur
Shastri National Award by President
Pranab Mukherjee in the year
2012
for
her
outstanding
contribution for making India selfreliant in the field of missile
technology. She is also an example
for a woman who is doing her best
in a male dominated society of ours.

Could you power a city with lightning
In Back to the Future, Doc Brown
uses lightning to power the De
Lorean sports car time machine so
that Marty can return to 1985. But
could lightning ever be harnessed
as a useable power source in the
future?
At first sight it appears promising
because a lightning bolt, which has
over five billion Joules of energy,
which could provide one household
with all their energy needs for a
month. However, Doc Brown had
an unbeatable advantage over us
– he knew when and where the
lightning was going to strike.
In the UK we experience relatively
few thunderstorms each year: in
England
thunder
occurs
on
average 11 days per year, with
even fewer in Scotland and Wales.
Even during a thunderstorm it’s
incredibly difficult to predict when
and where lightning will strike.

conductor, there would be major
difficulties in storing the energy and
then converting it to alternating
current so it can run your
appliances. In addition, any solution
to these problems would need to be
able to withstand the enormous
surges in energy generated by each
strike.
Finally, much of the lightning bolt’s
energy goes into heating the
surrounding air to temperatures
greater than the surface of the Sun.
So even if you managed to
overcome
the
problems
of
collecting, storing and converting
the energy from the lightning to
make it useful, you would still only be
harnessing a small proportion of the
lightning bolt’s power.

impurities please make my heart
your permanent abode”.
Make up your mind, make a whole
hearted sacrifice, to accomplish the
greater task in life, God never
considers the magnitude and type
of the work you do but observes our
love, devotion with which it is done.
Our spiritual progress does not
depend on the change of place or
work.
The nature of God is a circle of
which Centre is everywhere and
circumference is nowhere.
God is in history. God is in science,
God is in our conscience and all
these are one.
Whenever you pour sugar in water
after some time may see that the
sugar is dissolved, you cannot see
that, but you can feel the presence
of sugar only when you taste it,
similarly you may feel the presence
of God after undergoing certain
duties and circumstances.
A devotee prays to God to get rid of
mental impurities, lust, anger, greed,
passion, pride and jealousy.
A Sadhaka never aspires for
empheral world, his inner single
objective is to see the light and
peace. ‘A prayer of Tulsidas has the
message “oh! The lord of all souls! I
tell you this truth, I have no other
desire.” Give me the true devotion

The best way to stay where we are
and do all our duties for the love of
God. For years together man may
go on arguing and reasoning in
vain. But God reveals subtle spiritual
truth and his glory to the simple and
humble devotees. Now there is no
question of believing. I see God
every moment and longer I believe,
for I can see and experience God
knocking at the door, keep on
knocking and some or the other day
God feels your devotion and will
open the door of his grace.
Swami Vivekananda said “God
favors those who sincerely struggle
to realize him, if you are too idle to
do anything for God, you can take
granted for that he will never come
to you. Grace is given to those who
are constantly struggling for it and
never to lazy people”.
Sri Ramakrishna said, “His Grace is
blowing day and night unfurl the
sails of your boat and make of
crooked thoughts.” etc…..

We can offer prayers by standing or
sitting before the image or picture
of our favourite deity. It is true that
those who can visualize the picture
of God in their heart need no
external image to pray. The
essential requisites of a prayer are
devotion, faith and earnestness.
Those who would like to pray should
constantly repeat the name of the
Lord,
regularly
worship
and
meditate on their chosen deity,
read sacred books, recite hymns like
Ramarakshastrotra
and
Lalitasahasranama,
observing
fasting, devotional prostrations to
God
(Sahtangaparnams)
and
yeam for God’s grace with all
humility. These spiritual disciplines
gradually purify the inner self and
help him to get his vision, of course,
God is all powerful, merciful. He
who has taken shelter at the feet of
God, does not need to fear
anything. Your present difficulties of
today will not throughout the life.
Like the water flowing under the
bridge, difficulties will disappear,
don’t lose your patience. Be not
anxious, be patience. All the
difficulties that arise in life have a
meaning, they have cause. But
don’t regret what is past .God
watches everything. He hears every
word of your prayer. Don’t blame
God for not getting
what you
prayed for. God. No pain goes in
vain. Electricity flowing through the
electric wire is invisible, but the
glowing bulb confirms its presence.
Similar to the grace of God flows
through the wire of faith and
devotion. Repeating the holy name
AGNOSCO
one can experience it. Hence
repeat the name of God.
When gold is melted in fire, it
becomes pure, we realize that the
world is full of sorrows when afflicted
by difficulties. There is no real shelter
for us, other than the feet of God.
There is no way left for us than to
surrender to God. Pray to God,
whenever you face difficulties. God
will certainly show you the way out.
Just as the electricity generated in a
main power station, is supplied to
various places, the great souls who
have touched the feet of God
spreads
spiritual
awareness
everywhere.
This is not s figament of imagination
but a fact of experience which
nobody can deny thanks to modern
science and technology of ours.
Similarly we also get an insight into
the microscopic existence of matter
more commonly as microcosm.
Modern science gives us an insight
into the subtler aspects of matter.
Without going into details aspects of
matter. Without going into details
one statement about the ultimate
nature of matter would suffice; the
atoms are particles of the size of
about one tenth million of a
millimeter in diameter. Every atom is
composed of sub-atoms called
electrons , protons and neutrons
and this wonderful universe is built
by these bricks of basic subtle
material particles.
A perfect order and telling harmony
are seen in movements of huge stars
in the sky and in movements in
Page 21 of 36
minute electrons of the physical
bodies of men, animals and plants.
Modern scientific researches in the
west have demonstrated through
physical means the solidarity of the
unity of the whole universe. Going
one step further it indicates the idea
of the unity of the whole show – the
highest spiritual reality in which we
live, more and have our being. The
contemplation of cosmic harmony
reveal the existence of a supreme
being everywhere.
The great scientist Einstein, describes
this unity and harmony, thus” My
religion consists in a humble
admiration of the inimitable superior
spirit who reveals himself in the slight
details we are able to perceive with
our frail and feeble minds. That
deeply emotional conviction of the
presence of a superior power forms,
my
idea
of
God.
This is not an easy task. It cannot be
achieved in a day or two. With an
unrelenting longing to realize God,
we have to proceed on this path.

Immediately after the start of
academic year fresher’s start
dreaming about fresher’s day.
The very purpose of fresher’s
day is to welcome new comers in a
friendly
atmosphere
and
to
encourage their confidence,
It is a day where seniors and juniors
finally bond and unite to celebrate
being part of college,
The stage is set for fresher’s to show
case their talent and compete for
Mister & Miss fresher crown.
Yup...
One such saccharine moment
which was the mixture of little bit of
excitement, little bit of perplexion,
and with huge amount of hope to
come forth with surpass in the field
of technology, took place in our
lives.
The rationale for excitement was,
the events which were organized by
our wonderful seniors to encourage
and to get us the crown of miss &
mister fresher which was the
supremacy of the event and it was
grabbed by my pals Yashasvini and
Arun.

After going through this word every

But I was in hurry to get ragged, with

residing in some corner of me.
Many things were running in mind
like what will I do if it become
3 idiots type of ragging
“Jahapanah tussi great ho..Taufa
kabool karo”.
But it was joyful just because of our
soft hearted seniors, who made it
healthier, fun filled act for us.
Different kind of dares were given to
us, someone was asked to offer a
flower to unknowns present there
and to ask their names,
Another one was asked to
introduce himself and to sing a song
for them.
Like others I was also asked to
perform some dare, which was bit
