Nanotechnology ("nanotech") is manipulation of matter on an atomic, molecular, and supramolecular scale. The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter which occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size.

These slides apply the concepts from my course (Analyzing Hi-Tech Opportunities) to the field of nano-technology. Like the reductions in the feature sizes of transistors and metal lines on ICs (integrated circuits), in the micro-fluidic channels on bio-electronic ICs, and in the features of MEMS (micro-electronic mechanical systems), many physical phenomena become pronounced as the feature size decreases. Carbon nano-tubes, grapheme, quantum dots, nano-particles, and nano-fibers are examples of materials that benefit from small sizes. On the other hand, reductions in costs must be addressed through increases in the scale of production equipment and the creation of better processes; similar things occurred with other technologies such as displays and lighting.

A NANOTECHNOLOGY AIRCRAFT WITH STEALTH TECHNOLOGYIJRISE Journal
The success of the Aviation Industry (Defense) depends on various factors ranging from less visibility, reduction
of weight, availability of materials with multifunctional properties, carrying more payload, eco-friendly fuels, less fuel
consumption, faster and highly responsive communication systems, less or no repairs, extended and safe life, reduced time
frame of development cycle from concept to implementation and many more. Nanotechnology is recognized as a very strong
innovation driver and is therefore seen as a strategic technology for the world’s future economy. Nano-materials with their
exceptional multifunctional properties may transform the functioning of aviation (Defense) industry dramatically. Stealth
properties give it the unique ability to penetrate an enemy's most sophisticated defenses and threaten its most valued and
heavily defended targets. Stealth refers to the act of trying to hide or evade detection. It is not so much a technology as
a concept that incorporates a broad series of technologies and design features. Stealth does not always refer to radar.
Reducing an aircraft's heat signature is also important. This is usually done by channeling the engine exhaust through long
tubes and mixing it with cooler outside air. This paper shows the modern aviation design requirements like faster, miniature,
highly maneuverable, self-healing, intelligence guided, smart, eco-friendly, light weight warrant for materials with
extraordinary mechanical and multifunctional properties with stealth technology. Stealth technology is the use of special
radar absorbent materials, flat angular surface design and other techniques to minimize the amount of radiation r eflected to
a radar installation, causing an aircraft to appear as a much smaller signal or not at all. Stealth means 'low observable'.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
