What ‘chemicals of concern’ are in your food packaging?
Hazardous chemicals that persist indefinitely in the ecosystem have no place in a circular economy. Brand owners using packaging materials that contain per- and polyfluoroalkyl (PFAS), for example, should look for better replacements to ensure the health and safety of consumers and the environment. Per- and polyfluoroalkyl substances (PFAS) have gotten a lot of criticism […]

The fumigant Sulfuryl Fluoride intensifies the greenhouse effect
Abstract: A large amount of sulfuryl fluoride (SO2F2) is released into the atmosphere after fumigation, intensifying the greenhouse effect. Therefore, it is important to remove SO2F2 generated in fumigation. In this study, the solubilities of SO2F2 in 2-butoxyethyl acetate (BOEA), 3-methoxybutyl acetate (MOBA), 2-methoxyethyl acetate (MOEA), 1-methoxy-2-propyl acetate (MOPA), and 2-(2-ethoxyethoxy)ethyl acetate (DEOEA) were determined […]

Solar energy: Mixed anion compounds with ‘fluorine’ works as new photocatalytic material
Summary: Scientists have shown that an oxyfluoride is capable of visible light-driven photocatalysis. The finding opens new doors for designing materials for artificial photosynthesis and solar energy research. Full Story: Scientists in Japan have shown that an oxyfluoride is capable of visible light-driven photocatalysis[1]. The finding opens new doors for designing materials for artificial photosynthesis […]

Polymer solar cell hopes to claim new record?
By carefully tailoring the electronic properties and side-chain structure of a polymer, researchers have made one of the best performing organic solar cells yet. In tests in the lab, the polymer solar cell converts 14.2% of the energy in sunlight into an electrical current. If certified by one of the gold standard agencies for accrediting […]

Why the European Union Should Ban SF6
SF6, the most potent greenhouse gas in existence, was banned for all applications in the EU in 2014 – except in the electricity industry. The reason for the exemption, writes Nicholas Ottersbach, researcher at German cleantech startup Nuventura, was that there was no viable alternative. But according to Ottersbach that is no longer the case. […]

Optimization of fluoride removal from aqueous solution using Jamun (Syzygium cumini) leaf ash
Highlights Adsorbent was prepared by calcination at 500 °C. Jamum leaf ash (JLA) rich in calcium and calcium minerals favoured F– adsorption. F– adsorption was a complex process involving both boundary layer effect and intraparticle diffusion. Adsorption process of fluoride by JLA was spontaneous, feasible and exothermic. Removal of fluoride was done by adsorbent prepared from […]

Toothpaste alone does not prevent dental erosion or hypersensitivity
An analysis of nine toothpastes found that none of them protects enamel or prevents erosive wear Summary: An analysis of nine toothpastes found that none of them protects enamel or prevents erosive wear. Specialists stress that diet and treatment by a dentist are key to avoid the problems originated by dentin exposure. The rising prevalence […]

How can we provide clean water for everyone on Earth?
Of all the needs we humans share, none is as unifying as our need for safe drinking water. The World Health Organization recognizes this: Its water quality standards for the world’s poorest people are as strict as those set by the U.S. Environmental Protection Agency. Nonetheless, about 3.5 million people die each year because the […]

Slow-release fluoride devices for the control of dental decay
Abstract Background Slow-release fluoride devices have been investigated as a potentially cost-effective method of reducing dental caries in people with high risk of disease. This is the second update of the Cochrane Review first published in 2006 and previously updated in 2014. Objectives To evaluate the effectiveness and safety of different types of slow-release fluoride […]
