NUS chemists have developed a more effective method using heavy water splitting to swap hydrogen atoms on organic molecules with their heavier cousins (deuterium) for pharmaceutical applications.
Using the Atacama Large Millimeter Array (ALMA) in Chile, a team of researchers has detected the emission of deuterated formaldehyde (HDCO) from the hot inner region of the protostar HH 212. The finding, reported January ...
The quantum nature of hydrogen bonds in water manifests itself in peculiar physicochemical isotope effects: While deuteration often elongates and weakens hydrogen bonds of typical hydrogen-bonded systems composed of bulky ...
The origin of Earth's water has been an enduring mystery. There are different hypotheses and theories explaining how the water got here, and lots of evidence supporting them.
Advances in transmission electron microscopy (TEM) can allow cryo-imaging of biological and biochemical systems in liquid form, however, such approaches do not possess advanced analytical capabilities. In a new report now ...
Hydrogen fuel cells offer an attractive source of continuous energy for remote applications, from spacecraft to remote weather stations. Fuel cell efficiency decreases as the Nafion membrane, used to separate the anode and ...
Los Alamos Lab researchers have made the first simultaneous measurements of Ultra-Low-Field Nuclear Magnetic Resonance (ULF-NMR) and neutron imaging to visualize the movement of water in trees. Water use by trees is a key ...
A trip past the sun may have selectively altered the production of one form of water in a comet - an effect not seen by astronomers before, a new NASA study suggests.
Plants use photosynthesis to convert carbon dioxide and water into sugars and oxygen. The process starts in a cluster of manganese, calcium and oxygen atoms at the heart of a protein complex called photosystem II, which splits ...
The catalytic hydrogenation of N-heteroarenes showcases wide and important applications in the fields of synthetic chemistry, drug discovery, materials science, and hydrogen storage. However, it remains a long-standing scientific ...
