Background: Microbial fuel cells (MFCs) are a novel bioelectrochemical devices that can use exoelectrogens as biocatalyst to convert various organic wastes into electricity. Among them, acetate, a ...

Astronomers have identified the molecule methanol in the ‘warm zones’ of a protoplanetary disk circling a star about 360 light years from Earth. The finding is significant because although methanol - ...

ABSTRACT: The chemotactic responses of Meloidogyne incognita were studied in salt gradients in an agarose gel. Forty-eight combinations of sodium, copper, cesium, manganese , barium, potassium, ferric ...

This image shows the Rho Ophiuchi star-forming region in infrared light, as seen by NASA’s Wide-field Infrared Explorer (WISE). IRAS 16293-2422 is the red object in the center of the small square. The ...

What a sweet cosmic find! Sugar molecules have been found in the gas surrounding a young sun-like star, suggesting that some of the building blocks of life may actually be present even as alien ...

The structural origin of hard−soft behavior in atomic acids and bases has been explored using a simple orbital model. The Pearson principle of hard and soft acids and bases has been taken to be the ...
