IIT scientists use Jamun to create low-cost solar cells

NEW DELHI, INDIA: Scientists at Indian Institute of Technology (IIT) Roorkee have used the juicy, delectable Indian summer fruit Jamun to create inexpensive and more efficient solar cells. Researchers used naturally occurring pigment found in jamun as an inexpensive photosensitizer for Dye Sensitised Solar Cells (DSSCs) or Gratzel cells. Gratzel cells are thin film solar cells composed of a porous layer of titanium dioxide (TiO2) coated photoanode, a layer of dye molecules that absorbs sunlight. Read More

New process to make sustainable rubber, plastics

NEWARK, US: A team of scientists from the University of Delaware, the University of Minnesota and the University of Massachusetts – has invented a process to make butadiene from renewable sources like trees, grasses and corn. Butadiene is a molecule traditionally made from petroleum or natural gas, used to produce synthetic rubber and plastics. The findings in published online in the journal ACS Sustainable Chemistry and Engineering. The study’s authors are all affiliated with the catalysis centre for energy. Read More

Researchers develop glow sticks that detects cancer

TEL AVIV, ISRAEL: Chemiluminescence, or chemical light, is the principle behind the glow sticks (also known as light sticks) used at rock concerts and as quick tools to grab when the electricity goes out. But they can also be used to diagnose diseases by identifying concentrations of biological samples. A new mechanism developed by Tel Aviv University (TAU) researchers produces a 3,000-times-brighter, water-resistant chemiluminescent probe with particular application to medical and cancer diagnosis.

Thin layers of water hold promise for future energy storage

RALEIGH, US: Researchers at North Carolina State University have found that a material which incorporates atomically thin layers of water is able to store and deliver energy much more quickly than the same material that doesn’t include the water layers. The finding raises some interesting questions about the behaviour of liquids when confined at this scale and holds promise for shaping future energy-storage technologies. The paper is published in the journal Chemistry of Materials. “This is a proof of concept. Read More

Chlorochemicals industry: Plethora of opportunities in India


Chlorochemicals industry: Plethora of opportunities in India

The Indian caustic industry is a mature industry having a good growth that is keeping pace with expanding market demand. Also, the industry has adequate capacity to fully meet domestic demand, were part of some of the discussions at the Alkali Manufacturers Association of India (AMAI) conference on the theme ‘Development of Chlorochemicals Industry in India.’   Power costs remain high due to an imposition of taxes and cesses, even on captive power generation. The advantages of an efficient industry. Read More

Federal regulations for transporting liquid bulk chemicals

The trucking industry is highly regulated by the Department of Transportation (DOT) to ensure that cargo is transported safely. Companies must fully comply with all the rules and regulations set forth, or face stiff penalties and fines. One segment of the industry, hazardous materials transportation (HAZMAT) is under the watchful eyes of the Pipeline and Hazardous Materials Safety Administration (PHMSA). PHMSA is an agency within the DOT and its primary responsibility is the implementation regulations for transporting. Read More

Pelican unveils new water filter that removes chemical discharge

DELAND, US: Pelican Water Systems has unveiled a compact new lead/fluoride water filter system that can protect against the harmful effects of lead contamination and over-fluoridation. Designed with the challenges facing modern households, the filtration system targets chlorine, chloramine, fluoride, and dangerous contaminants to provide cleaner, spring-like water in every tap. The intuitive compact design makes this filter easy to install and use, even if consumers don’t live in a large home. The two-stage system can fit in tight quarters. Read More

Does Burgers Contain Hexane?

Do all veggie burgers contain hexane and does this mean I shouldn’t eat them? Veggie burgers don’t contain any hexane. Some soy protein ingredients in meat analogs and nutrition bars, which are listed on labels as soy protein isolate, soy protein concentrate or textured vegetable protein, have undergone hexane processing.In fact, hexane can be used as a healthy protein source for vegetarians. Hexane is classified as an air pollutant by the Environmental Protection Agency (EPA) and as a neurotoxin by the Centers for Disease Control.
