Hydrogen bonds: Scientists find new mechanism

(Phys.org) —Smaller begets bigger. Such is often the case for galaxies, at least: the first galaxies were small, then eventually merged together to form the behemoths we see in the present universe.

(Phys.org)—Although scientists know that when silicon mixes with water, hydrogen is produced through oxidation, no one expected how quickly silicon nanoparticles might perform this task. As a new study ...

DOE's National Energy Technology Laboratory (NETL) has developed a molten catalytic process for converting coal into a synthesis gas consisting of roughly 20% methane and 80% hydrogen using alkali hydroxides ...

Scientists at the US Naval Research Laboratory are developing a process to extract carbon dioxide and produce hydrogen gas from seawater, subsequently converting the gases into jet fuel by a gas-to-liquids process.

(PhysOrg.com) -- Recent work by scientists at Pacific Northwest National Laboratory has shed new light on the perplexing environmental chemistry of plutonium. They demonstrated that under anaerobic, or oxygen-free, ...

(PhysOrg.com) -- Researchers have long been interested in waste products as sources of biofuel. In Maine, those waste items could include treetops and limbs deemed by the forest products industry as unusable and often left ...

(Phys.org) —Using a laser, the St Andrews scientists can now carry out detailed analysis of a spirit sample no bigger than a teardrop and can even confirm whether it is toxic or not. It's hoped the testing ...

An international team of scientists using a new X-ray method recorded the internal structure and cell movement inside a living frog embryo in greater detail than ever before.

Spinning-disk confocal microscopy is an optical imaging technique that can be used to generate detailed three-dimensional fluorescence images of living cells and their contents. Although a powerful tool for ...

Most cells exist in a hydrated state and often live suspended in solution. In order to be imaged, cells must generally be frozen or dried, and then stained with substances such as heavy metals. Unfortunately, ...

Andong He saw a phenomenon at work in his breakfast bowl that he couldn't explain. It prompted this question: How does cereal shape influence the way cereals floating in the milk join?

(Phys.org) —Physicists may have created the smallest drops of liquid ever made in the lab. That possibility has been raised by the results of a recent experiment conducted by Vanderbilt physicist Julia Velkovska and her ...
