Mixtures of rare-earth metals (REMs) are notoriously difficult to separate, but a team of researchers from Harvard University (Cambridge, Ma.; www.seas.harvard.edu) has developed a method for efficiently extracting REMs with a high level of selectivity. By taking advantage of the…
The main mineral component of our bones and teeth — hydroxyapatite [HAP; Ca10(OH)2(PO4)6] — has been used by a Chinese team to develop a highly flexible paper with high antibacterial activity. The paper, made from silver nanoparticle-decorated ultra-long HAP nanowires…
Making more ARA Arcadia Biosciences Inc. (Davis, Calif.; www.arcadiabio.com) and Dupont Pioneer (Des Moines, Iowa; www.pioneer.com) recently completed field-trial validation for new safflower plants that produce high levels of arachidonic acid (ARA) oil, a high-value, specialty nutritional oil. The field…
Polylactic acid (PLA) is a versatile biopolymer, but its applications are somewhat limited due to its brittleness. Now, an alternative bio-based composite material has been developed that overcomes this limitation. Developed by the industry-university consortium of Hitachi Zosen Corp. (HITZ;…
A proprietary technology and patented process from GreenMantra Technologies (Brantford, Ont., Canada; www.greenmantra.ca) that produces synthetic waxes from underutilized plastic recycling streams, including films and bags, has reached commercialization. The company’s first industrial-scale manufacturing plant started up in May, and…
Scientists from Lawrence Livermore National Laboratory (LLNL; Livermore, Calif.; www.llnl.gov) have combined biology and 3-D printing to create the first reactor that can continuously produce methanol from methane at room temperature and pressure. The team removed enzymes from methanotrophs —…
Scientists from the National Chung Hsing University (Taichung, Taiwan; www.nchu.edu.tw), led by professor Ming-Yen Wey, have successfully developed an alternative route for recycling plastic solid waste. They used waste polystyrene to develop membranes suitable for processes such as carbon capture,…
Post-combustion carbon-capture processes that are based on adsorption of CO2 by amine compounds reduce the power output of coal- and natural-gas-fired power plants largely due to the energy required to regenerate the CO2 from the adsorbent material. In another approach,…
Colloidal glasses develop structural color through constructive interference. The color can be tuned by adjusting interparticle distance, making the colloidal glasses attractive for use as color pigments for use in coatings, displays, colorimetric sensors and optical barcodes. While colloidal crystals…
