Nano Tech Flashcards
What did Richard Feynman say about nanotechnology?
There is plenty of space at the bottom
What is the definition of nano products?
Those who are having at least one of their dimension in the range of 1 nm,to 100nm
Who used the term fourth industrial revolution?
World, economic forum, founderKlavs schwab
Give an example of nano ethics
It was found in an experiment that the spray of silver nano particles on a domestic waste. Water killed the bacteria as it can easily disturb the biochemical cycles like nitrogen, carbon, et cetera.
How are atoms arranged in graphite?
It is an allotrope and atoms are arranged in hexagon
What is the single layer of carbon atoms taken out of graphite called?
Graphene
Name some properties of graphene
It is one of the highest strongest and most conducting material known to the mankind
How can graff enebe used?
To develop nano transistors, just like rice, university developed us nano transistor of size of one nanometre.
Increasing the efficiency of solar cells.
Used in LEDs OLED screens.
Caffin is used in ultra capacitors for the storage of electricity.
Carbon nano tubes: these are one of the highest strongest along with that they exhibit electrical and heat conductivity
What are the uses of carbon nano tubes?
Composite materials since their weight to strength ratio is very low.
Carbon nano tubes are wonderful material for Nano sensor as soon as their environment changes, the conductivity of changes
Used in RO systems for deceleration of ocean water
Earth elevator 🤣🤣
What is TIFAC
Technology information forecasting assessment Council, it has started 26 mission mode projects to develop 26 different types of composites for Railways DRDOISRO, et cetera
What is neuroplasty city?
It is the brains remarkable ability to adapt reorganise and form new neural connections throughout life. It allows the brain to recover from injuries, learn new skills and adapt to changing environments.
What are the two types of drug delivery systems developed using nanotechnology?
Nano shells,
Targeted drug delivery system
What is Nano shell?
A layer of gold was quoted on silica particles with size in the range of one nanometre to 100 nm and injected in a rat having tumour in the neck. After that rat was exposed to infrared which was absorbed by shells. Temperature increased from 38°C to 45°C and that was enough to kill the Cancer cells
TDDS
A carrier molecule was fabricated by using nanotechnology and on the surface of that some chemicals were implanted. Then it was linked with a drug to be injected in the body of the patient.
How does ENOSE works
It is used for diagnosis developed by Israel Institute of technology:
The gold Nano particles are quite sensitive towards the change in environment. As soon as they come in contact with some substance, biomarker conductivity changes which is enough to identify the signature chemical to diagnose a disease.
How are organs made by using bio 3-D printing?
Stem cells are used along with AGAR gel medium having the nutrients
What is 4d printing?
When a 3-D printed material under predictable and reversible changes in its shape, texture, softness and hardness and response to temperature pressure voltage that is 4dprinting
How much data can 1 g of DNA Store?
10^14 mb of data
Where is DNA computing already been established?
In solving Hamiltonian path, problem or travelling salesman problem
To calculate the square root of certain figure.
To diagnose the infection and prescribing the treatment
What are Q dots
Quantum dots are nano scale semiconductor crystals that exhibit quantum confinement effects, examples, cam, sulphide, cadmium selenide, cadmium, Telluride
What light is emitted by large size, Kant, Yama dots and small size quantum dots
Large size emit red light and small size, emit blue blue light
When this quantum are in the body of cancer patient, it attach itself to the surface of the tumour, and when the laser, which is not absorbed by human tissue is illuminated the electrons in the quantum.excite and reach a transient state when they come back to their original energy level, dammit photos which helps to see the tumour with naked eye. You can also help in increasing the efficiency of solar cells as of now photon, striking the atoms excite one electron but the energy is not transferred and rather dissipated.
What are dendrimers
Synthetic tree like polymers, 3d nanostructure and monodisperse size
