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 ...
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 ...
Quantum chemical investigations into halogen compounds subject to relativistic effects have advanced understanding of bonding, reactivity and spectroscopic properties across the periodic table. As ...
Catalysts are essential for the chemical industry because they accelerate reactions and increase their yields. However, many of today's catalysts are based on expensive and environmentally harmful ...
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 ...
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 ...
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 ...

Master Bond Supreme 11AOHT is a halogen free, two component epoxy resin system for high-performance bonding and sealing formulated to cure at room temperature. Its most outstanding features include ...
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 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 ...
In aliphatic or aromatic compounds, the replacement of hydrogen atom(s) by halogen atom(s) results in the formation of alkyl halide (haloalkane) and aryl halide (haloarene), respectively. In case of ...
