ABSTRACT
Quantum Dots(QDs) are small conductive regions in a semiconductor, containing a number of charge carriers(from one to thousand) that occupy well defined discrete quantum states. They have typical dimensions between nanometers to a few microns .When the space at any side, around a material shrinks to 100Ã…, quantisation of the energy levels at the reduced side will occur. In quantum dots electrons are confined in all directions to a volume in space with dimensions on the order of their de Broglie wave lengt ....etc

ABSTRACT
A host of novel applications and new physics could be unleashed as Micro-Electro-Mechanical Systems (MEMS) shrink towards the nano scale. The time is ripe for a concerted exploration of Nano-Electro-Mechanical-Systems (NEMS) - i.e. machines, sensors, computers and electronics that are on the nano-scale. Many years of research by university, government, and industrial groups have been devoted to developing cutting-edge NEMS technologies for enabling revolutionary NEMS devices. NEMS has revolutionized nearly ever ....etc

AGING OF BITUMEN


INTRODUCTION:
Transportation facilities are required for the economic development of a country .

Population growth and economic development result extensive development of asphalt-paved roadways

Bitumen is used for coating in pavement construction .

Bitumen serves as a satisfactory binder in improvement of physical interlocking of aggregate bitumen mixes

Its properties changes as it ages in bulk storage , transport and storage on site.

The aging of bitumen then leads to deterioration of pavement
