The release of silver from industrial wastewater has caused serious environmental problems. Many methods have been developed to remove silver ions from industrial wastewater, including chemical precipitation, ion exchange, electrolysis, replacement, membrane and reverse osmosis. Several adsorbents have been used…
A new commercial manufacturing process for carbon nanotubes (CNTs) produces tubes in the range of 1–10 mm in length (5–12-nm dia.), two orders of magnitude longer than currently available CNTs, which typically have lengths from 5–20µm. “Despite attractive mechanical and…
Gas Innovations (La Porte, Tex.; www.gasinnovations.com) has signed a 15-year, pay-per-use agreement with Haldor Topsøe A/S (Topsøe; Lyngby, Denmark; www.topsoe.com) for a second on-site carbon-monoxide production unit, using Topsøe’s electrolytic Carbon Monoxide solution (eCOs) technology. The first eCOs unit in…
Scientists from Ulsan National Institute of Science and Technology (UNIST; Ulsan, South Korea; www.unist.ac.kr), led by Prof Jae Sung Son, have succeeded in producing high-performance, solid-state thermoelectric (TE) materials with liquid-like properties that can be easily brush-painted on surfaces of…
A collaboration between ExxonMobil Chemical Co. (EMCC; Spring, Tex.; www.exxonmobilchemical.com) and Thanh Phu Plastic Packaging Co. (TPPP; Ho Chi Minh City, Vietnam; www.thanhphupack.com) has resulted in the development and commercialization of laminate packaging materials that can be collected and recycled…
Large supermarkets routinely waste 500 lb of food daily from past-due produce, deli and meat scraps and other sources. A new process developed by California Safe Soil (CSS; McClellan, Calif.; www.calsafesoil.com) converts the nutrient-rich waste food into a liquid fertilizer…
For a long time, it has been believed that the crystallization of zeolites is, by nature, a very slow process. The hydrothermal synthesis of zeolites is normally performed batchwise, requiring crystallization times on the order of days. Now, Toru Wakihara…
Bio foam control Last month, Novozymes A/S (Bagsvaerd, Denmark; www.novozymes.com) introduced Fermax, an enzyme protease that prevents foam development during the sugarcane ethanol fermentation process, while delivering improved control and replacing chemicals. For an average size plant, trialing partners experienced…
Scandium International Mining Corp. (Sparks, Nev.; www.scandiummining.com) is about to become the first company to achieve production from a primary scandium mine, with its project near the small town of Nyngan, New South Wales, Australia. The production of scandium from…
Demand for carbon fiber (CF), which can be used to make strong, lightweight composite materials for improving vehicle fuel economy and wind-power generation, has been growing. However, widespread use of these advanced composites has been limited by the high production…
