Copper and cadmium exist naturally in the environment, but human activity can increase their concentrations to a point where they become a health hazard. Conventional wastewater treatment to remove those metals includes chemical precipitation, coagulation, flocculation, ion exchange, membrane filtration,…
At the end of last year, Mino Ceramics Co. (Nagoya City, Japan; www.mino-ceramic.co.jp) began shipping its first commercial high-temperature heat exchangers, which were developed in a project by Thermal Management Materials and Technology Research Assn. (TherMAT, Tokyo, Japan; www.thermat.jp). Developed…
Consisting of a land-based mechanical facility and underwater pipelines and accumulators, the underwater compressed-air energy-storage (UCAES) system from Hydrostor Inc. (Toronto, Ont., Canada; www.hydrostor.ca) takes electricity (potentially excess solar or wind energy) and uses it to run a compressor, which…
The recently commercialized high-speed turbo (HST) compressors from BOGE Kompressoren Otto Boge GmbH & Co. KG (BOGE; Bielefield, Germany; www.boge.de) produce 100% oil-free (Class 0) compressed air at the highest degree of efficiency and with minimal maintenance effort, according to…
There are many critical parameters that are important to monitor and measure in industrial polymer reactions, including molecular weight, viscosity and residual monomer concentration. Typically, polymer reactions are characterized offline and intermittently in a quality-control laboratory, or via inferential models…
PET recycling Polyethylene terephthalate (PET) can be quickly depolymerized into virgin monomers using a patented process that was developed, and is being scaled up by Ioniqa Technologies BV (Eindhoven, the Netherlands; www.ioniqa.com). The company recently finalized a multi-million-euro funding round…
A dry adhesive technology inspired by the microscopic hairs on gecko’s feet is said to be the first of its kind to be commercialized. Known as Setex, the technology was developed by nanoGriptech Inc. (Pittsburgh, Pa.; www.nanogriptech.com), a company spun…
Alkylate — the main component in high-octane gasoline — is produced by catalytic reaction of C3–C5 olefins with isobutane in the presence of strong acid catalyst. Although there has been progress in the use of solid-acid catalysts (see, for example,…
A process that converts methane into hydrogen and carbon black has been developed by researchers at the Institute for Advanced Sustainability Studies (IASS; Potsdam; www.iass-potsdam.de) and the Karlsruhe Institute of Technology (KIT; Karlsruhe, both Germany; www.kit.edu). In a joint project…
A new desalination membrane has been developed by an industry-academia collaboration team, led by professor Toshinori Tsuru at Hiroshima University (Japan; http://home.hiroshima-u.ac.jp/membrane/en/index.html). The work is the culmination of a five-year project that began in 2011 with support from the Japan…
