Researchers improve graphene DNA-detecting transistors

graphene-dna-detecting-transistors-1TSUKUBA, JAPAN: Researchers in India and Japan have developed an improved method for using graphene-based transistors to detect disease-causing genes. Graphene field-effect transistors (GFETs) can detect harmful genes through DNA hybridization, which occurs when a ‘probe DNA’ combines, or hybridises, with its complementary ‘target DNA.’ Electrical conduction changes in the transistor when hybridization occurs.

New catalyst mimics nature to break tenacious carbon-hydrogen bond

green-chemistry-au-catalyst-1Chemists discover new way to crack the stubborn carbon-hydrogen bond that could allow industry to make petroleum-derived commercial products easier, cheaper and cleaner. A new catalyst for breaking the tough molecular bond between carbon and hydrogen holds the promise of a cleaner, easier and cheaper way to derive products from petroleum, said a researcher at Southern Methodist University (SMU), Dallas. “Some of the most useful building blocks we have in the world.

Stable emulsions with a dietary fiber

innovation-food-emulsifiersEmulsifiers are used widely in the food industry to stabilise foods containing an oil and a water phase. However, the use of many traditional emulsifiers is often fraught with difficulties: they are additional sources of cholesterol, heat and acid sensitive, potentially allergenic, and mostly of animal origin. Alphadextrin, on the other hand, is able to both stabilise and texturize oil-in-water emulsions. Plus, the ring-shaped dextrin is 100 percent vegetarian, non-allergenic, cholesterol-free and obtained completely. Read More

Focus on plastics industry in Europe

international-focus-europe-plastics-industryIn an interview, Patrick Thomas, President, PlasticsEurope (European Association of Plastics Producers) and CEO of Covestro with Chemical Today magazine talks about the trends, challenges, and opportunities in European plastics industry. The European plastics industry provides direct employment to 1.5 million people in Europe, who work in about 60,000 companies, most of which are small and medium-sized enterprises (SMEs). In 2015, our region ranked second in world plastics production. Read More
