Tracking C–H bond activation with unprecedented resolution

Tracking C–H bond activation with unprecedented resolution

C-H bond The emission of methane, a highly potent greenhouse gas, is escalating due to livestock farming and the ongoing thawing of permafrost. Converting methane and longer alkanes into more benign and valuable chemicals presents an opportunity to mitigate these hazards while providing a vast resource for the chemical industry. Nevertheless, the conversion of methane […]

Organic compounds of sulphur that contain the group -S- linked to two hydrocarbons are known as thioethers. This alternative name to sulphides comes from the fact that they are analogues of ethers in which the oxygen is replaced by a sulphur; thioethers are generally more reactive than ethers, though. The formation of thioether structures increases […]

The observation of the neutrinoless double beta decay is the only practical way to establish that neutrinos are their own antiparticles. But, because of the small masses of neutrinos, the lifetime of neutrinoless double beta decay is expected to be at least ten orders of magnitude greater than the typical lifetimes of natural radioactive chains […]

Ammonia (NH3), a ubiquitous compound, was generated in excess of 187 million tons globally in 2020. Roughly 85% is employed in the creation of nitrogenous fertilizers, while the remainder is used for refining petroleum, producing various other chemicals, and manufacturing synthetic fibers like nylon. However, these processes come with a substantial energy expenditure. Presently, the […]

Our modern rechargeable batteries, such as lithium-ion batteries, are anything but sustainable. One alternative is organic batteries with redox-organic electrode materials (OEMs), which can be synthesized from natural “green” materials. A Chinese team has now introduced a new OEM for aqueous organic high-capacity batteries that can be easily and cheaply recycled. Traditional inorganic electrode materials […]

Food waste represents a serious problem associated with today’s society to which a solution should be found. A notable share of the impacts originates from the fishing sector. It hardly results acceptable that, in a world with shrinking food resources, 25% of the total fishing catches end up being discarded as waste. It should be […]

aerosol Author: Rubén Soussé Villa is pursuing a PhD in atmospheric chemistry at Barcelona Supercompting Center / Universitat Politècnica de Catalunya Mineral dust aerosols are microscopic rocky particles – for instance, sand – floating in the atmosphere. They are typically windblown from deserts, arid areas and agricultural lands, where they are produced from continued erosion […]

A new process that lets scientists chemically cut apart and stitch together nanoscopic layers of two-dimensional materials — like a tailor altering a suit — could be just the tool for designing the technology of a sustainable energy future. Researchers have developed a method for structurally splitting, editing and reconstituting layered materials, called MAX phases […]

Bio-mining pyrite with no oxygen

Bio-mining pyrite with no oxygen

BiochemistryBiologyChemistryGeosciences

By César Tomé

Pyrite, also known as “fool’s gold,” is an abundant iron sulphide mineral in the Earth’s crust. All organisms need iron and sulphur to grow. Because pyrite does not dissolve in oxygen-free conditions, scientists previously thought that organisms could not use pyrite in the absence of oxygen. Research shows that certain single-celled microorganisms can dissolve pyrite […]
