Oganesson: a most unusual ‘inert gas’

Posted on 19. July, 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.

A free review - Kinetics and mechanism of cationic micelle/flexible nanoparticle catalysis

Posted on 19. March, 2018.

The aqueous surfactant (Surf) solution at [Surf] > cmc (critical micelle concentration) contains flexible micelles/nanoparticles. These particles form a pseudophase of different shapes and sizes where the medium polarity decreases as the distance increases from the exterior region of the interface of the Surf/H2O particle towards its furthest interior region.

Comparative analysis of behavioural response of captive-reared and wild-trapped Northern Bobwhites to simulated predator attacks

Posted on 16. March, 2018.

Isolated populations of Northern Bobwhites (Colinus virginianus) have declined causing many landowners to attempt population restoration by releasing captive-reared birds. These attempts have resulted in high mortality rates, which we hypothesised are caused by captive-reared birds exhibiting more naive predator avoidance behaviour than wild birds.

Free Current Commentary - US withdrawal from the COP21 Paris Climate Change Agreement, and its possible implications

Posted on 15. March, 2018.

The global media have reacted with a combination of disappointment and dumbfoundedness, in the wake of the decision by the USA to abrogate its curbing of carbon emissions, as set forth in the Paris Agreement, at the COP21 United Nations Climate Change Conference in December 2015.

Free for 24 hours - Kinetics and mechanism of acetalisation of furfural to furfural diethyl acetal with Ni–Al layered double hydroxides containing Lewis acid sites

Posted on 14. March, 2018.

Acetalisation is a viable method to protect carbonyl functionalities in organic compounds and offers a potential synthetic strategy for synthesising derived chemicals. Furfural diethyl acetal is an important perfume material, which is usually obtained by acid catalysis in the acetalisation of furfural to furfural diethyl acetal using ethanol as a renewable solvent.

Prevalence of Toxoplasma gondii infection in domestic and migrating birds from Mazandaran province, Northern Iran

Posted on 13. March, 2018.

The zoonotic parasite Toxoplasma gondii is widely prevalent in humans and most warm-blooded animals worldwide, and is found in almost one third of the human population. There are a variety of modes of transmission of the parasite to intermediate hosts.
