One solution to this might be single-chain nanoparticles, which have recently become a hot topic in the field of polymer chemistry.2 Their applications range from sensing to recognition, and medicine to catalysis, but only a few groups have studied their synthesis and even fewer have looked at the introduction of metals.

The air in some UK homes contains potentially harmful levels of volatile compounds due to residents overusing household chemicals without proper ventilation, new research shows. Last year, a group led by Prashant Kumar from the University of Surrey, UK, showed that drivers stuck at traffic lights are exposed to 29 times more harmful pollution particles than those driving in free flowing traffic.

When dried, the densely crosslinked polystyrene networks can swell to accommodate organic molecules. Comments Off on Closing the window on air pollution. Pete Smith, from the University of Aberdeen, UK, and colleagues have assessed the impact that UK-based NETs could have on reducing the country’s CO2emission levels. Kit Chapman, Meet Yuri Oganessian, the elemental explorer forever immortalised on the periodic table, 2020-10-15T13:30:00+01:00By Katrina Krämer, They have been widely marketed as safer alternatives to traditional cigarettes as they do not contain tobacco, and their use has rapidly risen over the last decade. Anna Lea Rantalainen, an environmental chemist at the University of Helsinki, Finland, says the work raises further questions: ‘It seems that snow is efficient at removing aerosol particles from the air, but what happens after the snow has melted?’ If the sink is temporary, pollutant emissions could increase rapidly in industrialised areas when snow melts.

Scientists in Germany have successfully collapsed single polymer chains into dense nanoparticles, to make single-chain nanoparticles, by adding palladium.1 The nanoparticles mimic enzymatic pockets with defined environments around their metal centres and can catalyse a carbon coupling reaction.

No Comments » However, with homes becoming more insulated and energy efficient, and with people spending more time indoors, it’s worthwhile studying this air too. Smith’s team discovered that if the UK implemented all possible NETs, regardless of their technical viability, it would reduce current emissions by 8–32%. Bone cements have been used in surgery since the 1940s and work like a grout to fill the gaps between orthopaedic implants and bones.
