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.

2018: Year of the Bird
2018 marks the centennial of the Migratory Bird Treaty Act. To honour this milestone, National Geographic, the National Audubon Society, the Cornell Lab of Ornithology and BirdLife International are joining forces with more than 100 other organisations to celebrate 2018 as the Year of the Bird.
This effort aims to heighten public awareness of birds because of their wonder and beauty, and because they symbolise nature’s interconnectedness and the importance of caring for our shared planet.
To get started, visitors to BirdYourWorld.org will discover simple but meaningful steps that anyone can take to help birds each month and join a pledge to participate. These steps include participating in the worldwide Great Backyard Bird Count in February, putting in native plants in the spring, and cutting back on the use of plastic materials.

Through 12 months of storytelling, science research, and conservation efforts, Year of the Bird will examine how our changing environment is driving dramatic losses among bird species around the globe and highlight what we can do to help bring birds back.
Participating organisations include nonprofit and conservation groups, state and federal agencies, zoos, nature centres, and ornithological societies that are working together to raise the visibility of birds and inspire action through #BirdYourWorld throughout 2018. The campaign will also utilise National Geographic’s portfolio of media platforms reaching millions of people around the world with engaging bird content that will educate, inspire, and raise awareness about the challenges that birds are facing and what people can do to help.

Free from the Science Reviews archive: Zinc/ammonium formate: a new facile system for the rapid and selective reduction of oximes to amines

Posted on 1. March, 2018.

Abstract

Various oximes, both aldoximes and ketoximes, are selectively reduced to corresponding amines employing low cost zinc dust and ammonium formate despite presence of other functional groups such as halogens, –OH, –OCH3, –COOH, –CN, > C = C < and –CH3.

A convenient one-pot synthesis of 1-aryl-substituted 4-iodopyrazol-3-ols via aromatisation and oxidative iodination reactions

Posted on 28. February, 2018.

The pyrazolones, an important class of heterocyclic compounds, are prevalent in a wide range of bioactive compounds with pharmaceutical and agricultural activities. 4-Iodopyrazole-3-ols could open the way to a quick access to many pyrazolone analogues. However, iodination is usually difficult owing to the low electrophilicity of iodide.

Synthesis and properties of D–π–A structural imidazole-triphenylamine derivatives

Posted on 27. February, 2018.

Donor–acceptor π-conjugated (D–π–A) organic molecules bearing both electron-donating and electron accepting moieties linked by a π-conjugated bridge are an important class of organic functional materials, which exhibit intramolecular charge transfer from the donor to the acceptor moiety. Numerous D–π–A structural organic molecules have been synthesised and used in solar cells, organic light emitting diodes, nonlinear optics and fluorescence sensors.

Microbial biotransformation of α-ionol

Posted on 26. February, 2018.

α-Ionol is a megastigmane derivative belonging to the most important odoriferous degradation products of β-carotene in plants and it contributes to the characteristic fragrances of many flowers.In this study, the microbial biotransformations of α-ionol by fungi were examined with the aim of producing new derivatives that could be used as potential flavour and fragrance ingredients.

Strong inhibition of the Fe3+ + H2O2 reaction by ethanol: evidence against the free radical theory

Posted on 25. February, 2018.

The effect of ethanol on the catalytic decomposition of H2O2 by Fe3+ was investigated. While expecting a simple competitive oxidation of C2H5OH, far more complex kinetics were encountered experimentally: already minute amounts of C2H5OH (1% of H2O2) had a powerful retardation effect on the disappearance of H2O2.
