New mollusk and crustacean species in symbiosis with worms in dead coral rocks      (via sciencedaily.com)     Original source 

The symbiotic communities of invertebrates in dead coral gravel on the shallow, warm-temperate coast of the Kii Peninsula in western Japan. New bivalve species and sideswimmer have been found to live communally with the greenish Bonellia spoonworm. Live-in symbionts share the burrows of other organisms in sand and mud on the seabed. However, studies on burrow niches in rigid substrates, such as rocks on the seabed, have been scarce.

New recipe for efficient, environmentally friendly battery recycling      (via sciencedaily.com)     Original source 

Researchers are now presenting a new and efficient way to recycle metals from spent electric car batteries. The method allows recovery of 100 per cent of the aluminum and 98 per cent of the lithium in electric car batteries. At the same time, the loss of valuable raw materials such as nickel, cobalt and manganese is minimized. No expensive or harmful chemicals are required in the process because the researchers use oxalic acid -- an organic acid that can be found in the plant kingdom.

Cocoa pods -- a source of chocolate, and potentially, flame retardants      (via sciencedaily.com)     Original source 

As Halloween approaches, so too does the anticipation of a trick-or-treating stash filled with fun-sized chocolate candy bars. But to satisfy our collective craving for this indulgence, millions of cocoa pods are harvested annually. While the beans and pulp go to make chocolate, their husks are thrown away. Now, researchers show that cocoa pod husks could be a useful starting material for flame retardants.

Harnessing molecular power: Electricity generation on the nanoscale      (via sciencedaily.com)     Original source 

Researchers tested a molecular energy harvesting device that captures the energy from the natural motion of molecules in a liquid. Their work showed molecular motion can be used to generate a stable electric current. To create the device, they submerged nanoarrays of piezoelectric material in liquid, allowing the movement of the liquid to move the strands like seaweed waving in the ocean, except in this case the movement is on the molecular scale, and the strands are made of zinc oxide. When the zinc oxide material waves, bends, or deforms under motion, it generates electric potential.

Researchers develop organic nanozymes suitable for agricultural use      (via sciencedaily.com)     Original source 

Nanozymes are synthetic materials that mimic the properties of natural enzymes for applications in biomedicine and chemical engineering. They are generally considered too toxic and expensive for use in agriculture and food science. Now, researchers have developed a nanozyme that is organic, non-toxic, environmentally friendly, and cost effective.

An electrical switch to control chemical reactions      (via sciencedaily.com)     Original source 

New pharmaceuticals, cleaner fuels, biodegradable plastics: in order to meet society's needs, chemists have to develop new synthesis methods to obtain new products that do not exist in their natural state. A research group has discovered how to use an external electric field to control and accelerate a chemical reaction, like a 'switch'. This work could have a considerable impact on the development of new molecules, enabling not only more environmentally friendly synthesis, but also very simple external control of a chemical reaction.

Metal-organic frameworks could someday deliver antibacterial nitric oxide      (via sciencedaily.com)     Original source 

Because metal-organic frameworks (MOFs) — highly porous metal complexes — are so structurally and chemically diverse, they could be used for many applications, such as drug delivery and environmental clean-up. But researchers still need to get a better understanding of how they function, especially when embedded in polymers. Researchers have now developed and characterized nitric oxide (NO)-storing MOFs embedded in a thin film with novel antibacterial potential.

Bringing out the color in zinc      (via sciencedaily.com)     Original source 

Researchers have synthesized a zinc complex based on two zinc centers that absorbs visible light. They demonstrated that this capability depends on the proximity of the zinc ions, where the complex responds to visible light when the zinc atoms are closer. This new property is expected to expand the utility of zinc, which already offers advantages including biological relevance, cost effectiveness, and low toxicity.
