Q.1 a) Define
Nano-Technology. Explain the basic concepts of Nano-Technology.
Nanotechnology is a field of science and engineering that deals with the manipulation and control of matter on an atomic or molecular scale, typically ranging from 1 to 100 nanometers. To put it into perspective, one nanometer is one-billionth of a meter, or about 100,000 times smaller than the diameter of a human hair.
Bottom-Up
Approach: Nanotechnology often employs a bottom-up approach, where materials
and devices are built from molecular components, as opposed to traditional
top-down manufacturing methods. This involves assembling atoms and molecules
into desired structures, enabling precise control over properties and
functionalities.
Properties at
the Nanoscale: Materials exhibit unique properties at the nanoscale due to
quantum effects and increased surface area-to-volume ratio. For example,
materials may have altered electrical, optical, mechanical, or chemical
properties compared to their bulk counterparts.
Interdisciplinary
Nature: Nanotechnology encompasses various disciplines, including physics,
chemistry, biology, materials science, and engineering. It integrates knowledge
and techniques from these fields to design and fabricate nanoscale structures
and devices.
Applications
Across Sectors: Nanotechnology has diverse applications across multiple
sectors, including electronics, medicine, energy, environmental remediation,
and materials science. For instance, it's used in developing nanoelectronic
devices, targeted drug delivery systems, high-efficiency solar cells, and
lightweight yet strong materials.
Nanomaterials:
Nanotechnology involves the synthesis and characterization of nanomaterials,
such as nanoparticles, nanotubes, nanowires, and thin films. These materials
exhibit novel properties and find applications in various fields, ranging from
electronics to biomedicine.
Nanofabrication
Techniques: Nanotechnology relies on advanced fabrication techniques to create
nanoscale structures and devices. Examples include lithography, chemical vapor
deposition, molecular self-assembly, and nanoimprint lithography.
Safety and
Ethical Considerations: As with any emerging technology, nanotechnology raises
concerns regarding safety, health, and environmental impacts. Researchers and
policymakers need to address these issues to ensure the responsible development
and deployment of nanotechnology-enabled products and applications.
Overall,
nanotechnology holds tremendous promise for revolutionizing various industries
by offering unprecedented control over matter at the atomic and molecular
levels, leading to innovative solutions to pressing challenges and the
development of new technologies with enhanced performance and functionality.
b) Describe Nano Size
and Nano Seale with suitable examples.
Q.2 a) What are
techniques used in Nano Technology? Explain any one.
b) What is synthesis of Nano Materials? Also
describe the various properties of Nano Materials.
Q.3 a) Discuss top-down
and bottom-up approach with suitable sketch and list out the various methods of
top-down and bottom-up approach.
b) What is Nano bot?
List out the various applications of Nano bot.
Q.4 a) Explain the
working of Scanning Electron Microscopy (SEM) with suitable diagram. List outs
its advantages and applications.
b) Difference between
SEM and TEM.
Q.5 a) How do you apply
or use Nano Technology into energy sector? Explain in brief.
b) What is Energy
Conversion Process? Explain single stage and multistage energy conversion
process.
Q.6 a) Explain briefly
how Nano-Technology could be applied in Solar Energy.
b) What do you
understand about Micro Electro Mechanical Systems (MEMS) and Nano Electro
Mechanical Systems (NEMS)? Explain and list out its application.
Q.7 a) Explain the
working of Hydrogen Storage System with suitable diagram.
b) How Green Nano
Technology could be developed? Explain with steps by step procedure.
Q.8 a) Explain
Nano-Micro Silicon (Si) composite structure and what are the various
technologies used in silicon (Si) deposition.
b) How do you monitor
the various environmental factors by using sensors?
Q.9 a) How do you
prevent the pollution by using Nano Technology? Explain with suitable examples.
b) Discuss the various
applications of Nano Technology in Environment.
Q.10 Write short notes of the following:
a) Carbon Nano Tubes
b) Green Nano Material
