Abstract;
In order to examine the validity of model at organic/metal interfaces, the position of the vacuum level of N,N'-bis(3-methylphenyl)-N,N'-diphenyl--4,4'-diamine (TPD) film formed on various metal substrates (Au, Cu, Ag, Mg and Ca) was measured as a function of the film-thickness by Kelvin probe method in ultrahigh vacuum (UHV). TPD is a typical hole-injecting material for organic electroluminescent devices. At all the interfaces, sharp shifts of the vacuum level were observed within 1 nm thickness. Further deposition of ....etc

Crystalline-Silicon Solar Cells for the 21st Century


ABSTRACT
The worldwide market share for crystalline-silicon solar cells has
increased steadily in the last 10 years. In 1998, about 87% of the
photovoltaic modules shipped worldwide are based on crystalline
silicon. This dominance will likely continue into at least the first few
years of the 21st century. The long-term growth of crystalline-silicon
solar cells will depend on the development of low-cost polysilicon
feedstoc ....etc

Abstract
Throughout the history of mankind, tools have served the role as passive extensions of the body. Recently, the development of neuroprosthesis has changed the scope of how humans interact with tools. Neuroprosthetics enable direct interfacing with the brain and have the great potential for restoring communication and control in disabled individuals. The transformative aspect of direct neural interfaces is that they can be designed as intelligent tools that not only carry out intent but also have the capability to assist, evolve, an ....etc

Indian Geography in the 21st Century



VIEWS ON THE BOOK
Past intellectual trajectories and knowledge productions require both, a
sense of historical embeddedness of the discipline and a constant
questioning and reassessing the constructs therein. Agendas and visions
have to be continuously questioned and changed, reconfigured and
renegotiated and the onus rests primarily on the younger generation of the
scholars. The present book is an important contribution towards this

THE 21ST CENTURY SPACE SHUTTLE


Tomorrow s Shuttle:Cutting Risks in Half by 2005

Enhancements now under development could double the Shuttle's
safety by 2005: New sensors and computer power in the main engines
will see trouble coming a split second before it can do harm, allowing
a safe engine shut down. A new engine nozzle will eliminate the need
for hundreds of welds and potential leaks

Vacuum electronics technology is both old and new. It will continue to be enabling technology for entire classes of high power high frequency amplifiers with the most demanding specification for use in military and commercial systems. The report will give brief introduction on various vacuum electronic amplifiers such as helix TWT, gyro amplifiers, multiple beam-amplifiers, power modules along the basics and the advance in the past few decades with different performance curves.

The advantages and the future of these are mentioned in last pa ....etc

FUEL CELL CONCEPT

A fuel cell is a practical method of achieving a near reversible chemical reaction in which there is a conversion of chemical energy into electrical energy without even the intermediate step of conversion into random molecular energy (i.e. sensible internal energy). Thus whereas the harmonic and thermoelectric forms of direct converter are essentially heat engines and subject to the Carnot limitation on efficiency, the fuel cell is not. It was thought of that if such a device with hydrocarbon fuels or cheap derivativ ....etc
