A single-layer carbon allotrope has been prepared from a fullerene, the first time that a two-dimensional material has been constructed from nanostructures rather than atoms. 2D materials like graphene possess unique electronic and optical properties which arise from their repeating conjugated-carbon structure. This bonding pattern can be altered to tune physical characteristics such as the […]

Researchers in Austria, Norway and Slovenia have devised a strategy for synthesising polyethersulfone polymers using water as a monomer. The polymers can be used as polyelectrolytes in lithium-ion batteries in a step towards more sustainable devices. ‘Water, in general, plays different roles in synthetic [polymer] chemistry,’ says Christian Slugovc at the Graz University of Technology, […]

The European commission has proposed ambitious targets to limit pesticide use. It seeks to halve the use of synthetic pesticides in the EU by 2030, handing member states responsibility for introducing strategies and reduction targets. Pesticides would be banned in sensitive areas, such as parks, playgrounds, sports grounds and ecologically sensitive sites. The rules aim […]

A team of scientists based in France has discovered that the sounds made by ball-milling reactions can determine important chemical information. Ball-milling is a mechanochemistry process which grinds together solid reactants using moving metallic balls in a specially designed reactor. ‘Mechanochemistry is the future’, comments Lars Borchardt, whose research, at Ruhr University Bochum in Germany, […]

There is a strong tendency to regard the so-called scientific revolution in the seventeenth century as a revolution of the mathematical science i.e., astronomy and physics, but as I have pointed out over the years many areas of knowledge went through a major development in the period beginning, in my opinion around 1400 and reaching, […]

Orbitalets – a type of localised molecular orbitals – depict chemical reactivity in large molecules in a more intuitive way than other orbital descriptions. Like other frontier molecular orbitals, orbitalets express the quantum mechanical nature of electrons in molecules. They help chemists understand compounds’ reactivity and regioselectivity. But in large molecules with many delocalised electrons, […]

At least 13 people have been killed, and over 250 more hospitalised after a tanker full of liquefied chlorine gas dropped from a crane during loading at the port of Aqaba in Jordan. The incident occurred in the afternoon of 27 June. Footage released by state television shows the tanker falling from a crane during […]

Light-activated molecular machines have been created that act as a broad-spectrum ‘antibiotic’ to mechanically damage bacterial cell membranes. Although this research is currently at an early pre-clinical stage, initial in vivo studies are encouraging. Modern antibiotics revolutionised medicine following their discovery in the 20th century, but years of misuse now mean that antibiotic resistance is […]

A carbon capture plant that has opened in Northwich is the largest such project in the UK. The £20 million facility will convert 40,000 tonnes of carbon dioxide into food and pharmaceutical grade sodium bicarbonate each year. Carbon capture technology that removes carbon dioxide from the waste streams of industrial sites is a key part […]

Two strangers with similar body odour are more likely to become friends, a study by scientists in Israel has found. It shows that despite being an underappreciated sense, smell can play an important role in how people form and maintain social bonds. ‘People constantly, but mostly subconsciously, sniff themselves and others,’ says Inbal Ravreby from […]
