Can India replicate Middle East’s desalination success story


As concerns over air-pollution loom large ahead of Diwali, scientists at Council of Scientific and Industrial Research (CSIR) have formulated eco-friendly crackers, which would not only cause reduced emissions, but would help people get a reprieve from noise pollution during festivities. “Green crackers are basically reduced emission crackers wherein we reduce some harmful components, like barium, aluminium and chromium which are conventionally used to get different colours. So, the strategy is to reduce or replace these components with less toxic chemicals which can bring down emissions to significant levels,” said Director Dr Rakesh Kumar, CSIR-National Environmental Engineering Research Institute (CSIR-NEERI).

Water is an essential ingredient in across industries, not just in the products but also in the preparation for cleaning the products, processing and other uses. While 71 percent of the earth’s surface is covered with water, only a tiny amount (0.6 percent) is fit for consumption. The supply of clean and fresh water is fast decreasing. In contrast, the demand for consumption of water is fast increasing due to a growing global population, agricultural activities and economic development. Pressures from both, the supply and demand sides means that clean water is increasingly becoming hard to source. While the future outlook for India’s capability to meet the growing demand seems to be grim, India can perhaps turn to their neighbours in the middle east to replicate their desalination model. Read More

Roald Hoffmann – co-developer of Woodward–Hoffmann rule

Biography & contributions: Roald Hoffmann the organic chemist, was born on July 18,1937. Hoffmann was the Nobel laureate at the time of 1981 for the work quantum mechanics. Hoffmann applied the theories of quantum mechanics from the filed of physics to explain chemical reactions and chemical compounds.He investigated both organic and inorganic substances. Hoffmann was introduced the principle called isolobal principle. Hoffmann in the years of 1955 and 1956 studied the chemistry of cement and hydrocarbons. Hoffmann along with other Nobel laureate Woodward used quantum mechanics to develop rules that would enable scientists to predict whether a particular compbinations of chemicals will reult in a reaction. Read More

Biesterfeld Plastic has extended its mutual distribution agreement with Solvay. Biesterfeld will distribute Solvay’s sulfone polymers, in Switzerland beginning in January 2019. The product portfolio includes the Udel PSU, Radel PPSU and Veradel PESU brands. These products have been selling by Biesterfeld in many areas of Europe since 1998.  Udel PSU (polysulfone) is a tough, rigid, high-strength, transparent plastic that offers higher heat resistance and better hydrolytic stability than polycarbonate (PC). It retains its good mechanical properties when exposed to steam and other sterilization techniques. Read More
