Now available on Fast Track: Oganesson: a most unusual ‘inert gas’

Posted on 18. May, 2018.

Oganesson, with the symbol Og, is the artificially prepared (i.e. ‘man-made’) elementwith atomic number 118, previously known as eka-radon or Uuo (‘ununoctium’), and recently ‘blessed’ with an official name by IUPAC3. Atoms of the element were first produced using the U400 cyclotron at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, via a heavy-ion fusion reaction utilising collision of a 4820Ca beam with a 24998Cf target.

“Vibrational bonding”: a new type of chemical bond is discovered

Posted on 12. March, 2015.

Chemical bonding is the attractive force between atoms that causes them to form into aggregates such as molecules or solids. At its foundation, a chemical bond is always a result of the summed attractive and repulsive electrostatic interactions between a number of positively charged nuclei and a number of negatively charged electrons, but a hierarchy of different bond types of varying strength can be identified.

Free from the Science Reviews archives - Superconductivity

Posted on 9. March, 2015.

Superconductivity is one of the most explicit and dramatic forms of electronic order. We are baffled by its consequences, for example the complete breakdown of electrical resistance, the expulsion of small magnetic fields, the Josephson effect and magnetic levitation. But at a more conceptual level, the processes underlying these phenomena are equally captivating: why does a superconductor superconduct?

Free from the archives - One-pot synthesis of 2-amino-4-aryl-5-oxo-5,6,7,8-tetrahydro-4H-1-benzopyran-3-carbonitriles in aqueous media

Posted on 5. March, 2015.

The selective manipulation of one functional group in the presence of other(s) using nontoxic chemicals in economically viable and environmentally benign conditions is a formidable task for synthetic organic chemists. There is a growing interest in carrying out synthetic transformations in aqueous media.

Trophic niche and feeding strategy of the White Stork (Ciconia ciconia) during different phases of the breeding season

Posted on 5. March, 2015.

Food supply is one of the ecological factors that influence life-history traits, population sizes and community structure in birds. Indeed, understanding both the ecological continuity of animal species and their ecological niches is greatly dependent on food restriction and its variations in quality and quantity.

A QM/MM study of NO oxidation on the nanocrystalline surface of tungsten oxide

Posted on 5. March, 2015.

Nitrogen oxides play a major role in air pollution, particularly in the creation of acid rain and photochemical smog. Among the methods that can be used to capture or eliminate these pollutants are adsorption on the surfaces of metal oxide semiconductors (MOSs) and followed by conversion into other materials.

The transition from iron starvation to iron sufficiency as an important step in the progression of infection

Posted on 4. March, 2015.

Iron is an essential micronutrient for microbial life. At the start of an infection the host environment will normally restrict available iron, and innate immune responses will aim to further reduce iron, thus inhibiting growth of potential pathogens.
