Clariant has teamed up with Lavergne, a leader in the production of sustainable engineering resin from recycled plastic, to develop halogen-free flame-retardant polyester compounds made from ...
SLH compounds, for example, have been found to react and reduce the levels of ozone in the atmosphere—an interaction that, in theory, should lead to cooling. But SLHs can also exert a warming ...
Quantum chemical investigations into halogen compounds subject to relativistic effects have advanced understanding of bonding, reactivity and spectroscopic properties across the periodic table. As ...
Lanxess is expanding its range of halogen-free flame-retardant compounds based on polybutylene terephthalate (PBT) to include variants with outstanding fire resistance in glow wire tests. The first in ...
Organohalogens like perchloroethene and trichloroethene are prominent groundwater pollutants due to their industrial use as dry cleaning and degreasing agents and their widespread release into the ...
THE FIRST DIRECT atmospheric measurements of iodine oxide and bromine oxide above the Antarctic snowpack unexpectedly indicate that the chemicals participate in destroying ozone and change the ...
Electronics companies have experienced some chemical reactions in the past two decades. Many will recall the European RoHS Directive (Restriction of Hazardous Substances), which came into force in ...
It was observed by C. W. Rice in 1944 that the emission of positive ions from a platinum anode heated in air is increased very markedly when vapours of compounds containing halogens such as carbon ...
The ETH Zurich student team’s H2-Sling aircraft, featuring a hydrogen fuel cell system with Type 4 carbon fiber tanks, awaits Swiss regulatory clearance for a maiden flight ahead of a planned crossing ...

I was looking at the periodic table of the elements the other day, as one does, when my eye fell upon the right-hand side of the chart. Right next to the noble gases at the extreme edge of the table ...
