one of the basis of the tremendous revolution in electronics has been the enormous advances in materials science. Whether it is the accuracy of photolithography or the ability to fabricate extremely pure materials, microelectronics would not be possible without concomitant growth of material science. An important requirement for the fabrication …

FOR Most of us, an antibiotic is a drug used to fight infections. But very few of us know about the hard work that has gone into making these little pills that boost out immune system and help fight germs and viruses. Antibiotics are essentially very complex molecules. Sir Alexander …
liquid crystal displays (lcds) are ubiquitous in modern electronic devices. From cellular phones to laptop computers and now televisions, they form an integral part of most consumer electronics. Given their importance, a lot of research is going on to improve the existing technology and have qualitatively better displays for the …
LINKING together individual molecules to make complicated structures, much in the same way as children playing with Lego, chemists are now trying to construct materials whose properties they can fix beforehand. At least half a dozen groups in USA, Canada, Europe and Australia are assembling large arrays of molecules to …
BUCKYBALLS or fullerenes, a newly discovered form of carbon, have opened up a new field in carbon chemistry and new applications are coming to light in electronics and electrochemistry. Japanese scientists have recently made thin films of fullerene crystals that show the electrical behaviour of semi-conductors such as silicon. Other …
THE GRAVITY-FREE environment in space will form more perfect crystals of certain proteins and scientists hope that by understanding their protein structure, they will be able to design better drugs to combat diabetes and arthritis, along with some other diseases. A protein derived from the deadly toxin found in castor …
