Electron transfer is a process by which an atom donates an electron to another atom. It is the foundation of all chemical reactions, and is of intense research because of the implications it has for chemistry and biology. When two molecules interact, electron transfer takes place in a few quadrillionths (10-15¬) of a second, or femtoseconds (fsec), meaning that studying this event requires very time-sensitive techniques like ultrafast spectroscopy. However, the transfer itself is...

A research team at Ulsan National Institute of Science and Technology (UNIST), S. Korea, found a new physical organogel electrolyte with two unique characteristics: an irreversible thermal gelation and a high value of the Li+ transference number. A Recent fire on a Boeing 787 on the ground in Boston, US, was caused by a battery failure, it resulted in the release of flammable electrolytes, heat damage and smoke. If they had used a safer electrolyte, the risk would have been reduced....

Aerosols May Have Helped Suppress Hurricanes During 20th Century
2013-06-24 14:55:45

Lee Rannals for redOrbit.com – Your Universe Online Researchers wrote in the journal Nature Geoscience that aerosols could have played a role in helping to suppress the number of Atlantic hurricanes over the 20th Century. The scientists found that aerosols make clouds brighter, which causes them to reflect more energy back from the sun into space. This impacts ocean temperatures and tropical circulation patterns, making the conditions less favorable for hurricanes. "Industrial...

Simple And Inexpensive Process To Make A Material For CO2 Adsorption
2013-06-17 09:17:59

Ulsan National Institute of Science and Technology(UNIST) Researchers from Ulsan National Institute of Science and Technology (UNIST), S. Korea, developed a novel, simple method to synthesize hierarchically nanoporous frameworks of nanocrystalline metal oxides such as magnesia and ceria by the thermal conversion of well-designed metal-organic frameworks (MOFs). The novel material developed by the UNIST research team has exceptionally high CO2 adsorption capacity which could pave the way...

Chemistry is a physical science concerned with the composition, structure, and properties of matter. It also deals with the changes that matter undergoes during chemical reactions. It incorporates the studies of various atoms, molecules, crystals and other aggregates which can be combined or isolated and concepts of energy and entropy through which chemical processes occur. Modern chemistry (from the Egyptian kēme, meaning "earth") evolved from alchemy following the chemical revolution...

In chemistry, salt is a general term used for ionic compounds composed of positively charged cations and negatively charged anions, so that the product is neutral and without a net charge. These ions can be inorganic (Cl-) as well as organic (CH3-COO-) and monoatomic (F-) as well as polyatomic ions (SO42-). Solutions of salts in water are called electrolytes. Electrolytes as well as molten salts conduct electricity. Zwitterions are salts that contain an anionic center and a cationic...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
