Nano technology has a large number of applications in different fields of science and technology. Nano particle are the tiny particles which are being used in upcoming technology due to their small size and high capability. The properties of nanoparticles depend largely on their synthesis procedures. There are different methods for the synthesis of nano particles using differen...

THE ANCIENT WORLD passed from the Stone Age through the Bronze and Iron Ages to our modern developed society—a society that is dependent on metals and alloys for its very existence. However, an impressive body of metallurgical knowledge developed in the thousands of years since ancient man first found copper and became curious enough to investigate the behavior of this naturally occurring, rela...

Nonenzymic browning and corrosion were monitored in commercially canned single-strength grapefruit juice stored for 15 weeks at 10°, 20°, 30°, 40°, and 50°C. Browning did not occur in juices stored at 10° and 20°C, but began to ap pear after 9 weeks in juices stored at 30°C. Browning was quite evident within 3 weeks for juices stored at 40° and 50°C. Plots of nonenzymic browning versus corrosio...

A magnetocaloric effect (MCE) with sizable isothermal entropy change (ΔS) maintained over a broad range of temperatures above the blocking temperature is reported for rare earth-free superparamagnetic nanoparticle system comprising Fe–TiN heterostructure. Superparamagnetic iron (Fe) particles were embedded in titanium nitride (TiN) thin film matrix TiN/Fe/TiN multilayered pattern using pulsed l...
