- Every subject is interlinked and we don't realize it.
- Studying Nature is nothing but Technology. Not only the Nanotechnology from mosquito but much more.
- Drinking lots of water give us less or no diseases.
- Boiled water just quenches our thirst.
- Our brain is more brilliant than us. As we do somethings without any reason like rubbing our forehead while thinking or in tension.
- Nervousness can be reduced by drinking water.
- Learning Physics makes us think practically. And beyond physics is Philosophy.
- Nothing is impossible unless we think we can't make it.
- Our attitude is depends on what we eat.
- Concentration comes with interest and interest can be created by ourselves.
- Good student always writes down the matter which he/she wants to remember.
- Our desires can be achieved by doing them by heart, not by brain.
- Heart is throughout our body which we don't realize.
- And the most important thing is Education is Fun.
GOOD EVENING SIR,
ME ARPIT SHUKLA (1st year,MECHANICAL-B),AURORA ENGINEERING COLLEGE.
NANOTECHNOLOGY IN MECHANICAL ENGINEERING
what is nanotechnology?
Nanotechnology deals with nanosized particles and devices.
Nanoscale uses "nanometer" as the basic unit of measurement and it
represents a billionth of a meter or one billionth of a part.
One-nm is about 3 to 5 atoms wide.This is very tiny when compared
normal sizes day to day encounter.
for example this is 1/1000th the width of human hair.
Any physical substance or device with structural dimensions below 100
nm is called nanomaterial or nano-device.
Nanotechnogy is dependent on the technolgy that involves fabrication
of material,devices and systems through direct control of matter at
nanometer length scale or less than 100 nm.
Nanoparticles can be defined as building blocks of nanomaterials and
of ceramics,metal,non-metal,metal oxide,organic or inorganic.
At this small scale level, the physical, chemical and biological
properties of materials differ significantly from the fundamental
properties at bulk level.
Nanomaterial can be physically and chemically manipulated to alter the
properties, and these properties can be measured using nanoscale
sensors and gages.
Nanoscience is divide into two fields:-
NANOFABRICATION and NANOTECHNOLOGY
Nanotools are required for manipulation of matter at nanoscale or atomic level.
Certain devices which manipulate matter at atomic or molecular level
are scanning-probe microscopes, atomic force microscopes, atomic layer
deposition devices and nanolitography tools.
Nanolithography means creation of nanoscale struture by etching or printing.
Nanotools comprises of fabrication techniques, analysis of metrology
instruments, software for nanotechnology research and development.
Softwares are utilized in nanolithography, 3-D printing, nanofluidics
and chemical vapour deposition.
Nanoparticles and Nanomaterials.
Sub: A Document on guest lecture given by Dr. T P Sasikumar sir
Ref: Guest lecture given by Dr. T P Sasikumar sir at AEC, Bhongir, Nalgonda dist. On
My name is pavankumar sir. I am studying mechanical engineering first year
at aurora engineering college, Bhongir. Today I was very much thrilled with your lecture sir.
This gave me sufficient guidance to proceed further. As you asked us to prepare a
Document on today’s lecture I am going to repeat some points which attracted me.
Ø Learn the subject with interest and enjoyment that means with heart and
not by brain.
Ø Every person must know the importance and application of the particular
Ø You also interlinked and proved why physics is not different from chemistry by taking the example of 2 metals and by explaining the different types of bonds involved between them.
Ø Atom size calculation is explained by taking the example of the thickness of
Paper-such as by taking and calculating the thickness of 100papers or sheets and dividing with 100.
Ø To make the class interesting we should read the topics which are going to be
discussed the next day by the faculty.
Ø ¼th of knowledge will be given by faculty,1/4th should me learnt by students and
remaining portion can be gained by interacting with our classmates
Ø we must interact with any of our classmate and ask him to prepare on a particular topic.
Ask him to prepare a question paper on the topic and try to solve the paper which was prepared by him and try to give a question paper to him which was prepared by you.
Ø We also learnt how geography, geophysics are related to physics.
Ø We also learnt how electricity flows in the circuit-such as an excited state of electron is called electricity and it flows only through the peripherals and not through the centre of the circuit.
Ø If a person want to get interest in a subject he or she should first see the topic in the text book and should close the book for a while and after some time we should write what we know about the particular topic without referring .Then we can find the unknown part and thereby an anxiety grows which leads to an interest towards the subject.
Ø If a person wants to be a good student firstly he or she should note the important points in the class and if we have any doubts we should discuss with the classmates or search on the internet until we get the right and clear picture about the doubt.
Ø We have to prepare notes which make our conceptual study easy.
Ø We also discussed and learnt about nanotechnology by taking an example of mosquito-in which we have learnt about how a crunchy biscuit turns to soft when a mosquito sits on it
Ø Our brain knows about us .so “your brain knows you very well” and our brain is too intelligent than us.
Ø We also discussed why nanotechnology is used widely than micro technology by taking example of atom-such as nanotechnology can study by magnify an atom up to 10 to the power 9 where as micro technology can be explained up to 10 to the power of 6.
Ø At last after having awonderful lecture we concluded with a small remembering game.
v Last but not least we also learnt that “we should not waste time ,we should invest time”
Thanking you sir,
Good evening sir, we are very much inspired by the way you have motivated us today in session.
thanks to you by which we have learnt many things like
1.How different subjects are related to each other.
3.How to cool some one's anger.
4.How to make morning of a day thrilling (though funny but true...!).
5.Why people are different in their physical appearance in different places.
6.Good students behavior.
7.Concentration and interest.
8.Importance of MANAS over BUDDHI.
9.Positive thinking and attitude.
10.Learning and sharing.
i hope we have further session like today's
this feedback is by :
T.UDAY KIRAN (11621A03B7)
I am really very thankful to your valuable lecture yesterday , I have been to your lecture which was held by LUGI way back in 2008 . I was very much impressed by your speech over there
,sir but yesterday's speech was really awesome sir you have shown me how to enjoy studying in a easy manner and i have also realized that no subject is hard until u try to over come it.
SIR i have a question for you
" DO U ACTUALLY FOLLOW THE LIVING ACCORDING TO VEDAS OR WILL UR APPROACH BE IN A SCIENTIFIC MANNER" please let me know this and I also want to be a part of your HP program sir.
EEE -1st year,
my self keshav raj from EEE-A, with the response to ur class i am sending this mail
the following r the points which are dissusied by u today
1) we interlinked phy with geography
similarly interlinkage of phy with bilology etc
Evolution of nanotechnology
about nano science
Thermodynamics in body
How life changes
The blogs u write
How a student can Consentrate on studies
HOW a good student will be
How can we learn ur self
I learnt that when we read getting information is one thing n getting doubts is also should be otherside
we must learn ourselfs
and also we must realise that Brain is more intelligent then Body
A good student is who who possess a question
wat is manusu n ts Behaviour \
"CHEAT YOURSELF IF U REALLY WANT TO LEARN " is the main thing i learnt
APART from this i want some suggestion from u sir ,actually i get depressed very quickly can u please suggest me how to get ride of this problem ???????
