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
