New electronic nose with biodegradable polymer and monomer can detect hydrogen sulphide from sewers

Apr 13, 2021 The impersonation of ORN with the help of an organic electronic device consisting of biodegradable polymer and monomer under Dr. Channabasaveshwar  Yelamaggad from CeNS and Prof. Khaled N. Salama, Sensors lab, Advanced Membranes, and Porous Materials Center, King Abdullah University of Science and Technology (KAUST), Saudi Arabia has been published in the journals  ‘Materials Horizon’ and  ‘Advanced Electronic Materials’ recently. The fabricated sensor consists of a heterostructure consisting of two layers – the top layer a monomer and is realized with a novel chemical tris (keto-hydrazone), which is both porous and contains H 2S specific functional groups, and the bottom layer is the active channel layer which plays a key role in altering the current and mobility of charge carriers.

What the Coronavirus Variants Mean for Testing

What the Coronavirus Variants Mean for Testing Most tests should be able to detect the variants of concern, but test developers and health officials must remain vigilant, scientists say.

Using this genomic sequence, scientists scrambled to design a large assortment of diagnostic tests for the virus. But the virus has mutated since then. And as the coronavirus has evolved, so has the landscape of testing. The emergence of new variants has sparked a flurry of interest in developing tests for specific viral mutations and prompted concerns about the accuracy of some existing tests.

Human alterations to aquatic ecosystems increase methane emissions

Washington [US], April 11 (ANI): Atmospheric methane has tripled since pre-industrial times. It traps heat far more effectively than carbon dioxide and accounts for 25 per cent of atmospheric warming to date, and much of that methane is coming from aquatic ecosystems, with human activities contributing to the emissions levels, a new paper published in Nature Geoscience has found.
