The chemistry of semiconductors

Semiconductors are vital components in the modern technologies that we use in our everyday lives, both in industrial automation and consumer products. Computers, automobile electronics, smartphones and other “smart” devices, robotics and medical devices that depend on semiconductor chips are…

Pilot planned for electrochemical extraction of REEs and other critical metals

Construction is planned for a pilot plant that will demonstrate a modular electrochemical technology for extracting rare-earth elements (REEs) and nickel from industrial wastes, such as coal ash. The startup Blueshift (Boston, Mass.; www.buildblueshift.com) recently announced venture capital funds that…

Differences of Temperature-control Devices: Heat Exchangers, Coolers and Heaters

Understanding the differences among key temperature-control devices, such as heaters, coolers and heat exchangers, allows users to realize their unique benefits When it comes to temperature control in industrial, commercial and residential settings, three key devices are often considered: heat…

Two-pronged approach recycles textile waste while also producing glucose

Glucose is a key pillar in producing bio-based alternatives to conventional chemicals, but finding industrially viable, non-food-competitive sources for glucose has proven challenging, due to the difficulty in obtaining glucose from hemicellulosic materials, such as woody biomass, in a cost…

Seawater-derived solids can serve as carbon-negative components of concrete

Aggregate — solid materials like sand, gravel and crushed stone — is combined with cement to make concrete, the world’s most widely used human-made material. But sand is in short supply, so there is a need for alternate materials to…

Short-loop battery recycling uses vegetable-oil nanoemulsion

Efficient and sustainable recycling of lithium-ion batteries is a crucial element in electrifying transportation. Black mass is a mixture of cathode and anode materials remaining after disassembly and shredding of end-of-life lithium-ion batteries (LIBs). Many valuable materials, including lithium and…

An integrated process makes valuable mid-chain carboxylic acids from organic waste

A dual process strategy bridging fermentation and electrochemistry is enabling the production of mid-chain carboxylic acids (MCCAs) — important and valuable precursors to a number of products — using inexpensive organic waste streams from breweries, distilleries and dairies. Developed by…

Selective silica removal makes for better bauxite beneficiation

The extraction of alumina from bauxite is significantly impacted by the silica content of the ore — specifically the presence of silica in kaolinite (Al2Si2O5(OH)4). This is because traditional bauxite-beneficiation methods, such as washing, flotation and particle-size separation, also typically…
