Professor Masafumi Unno and colleagues at Gunma University (Kiryu City, Japan; element.chem-bio.st.gunma-u.ac.jp) have developed a simple method for the synthesis of “Janus cubes,” which are nano-sized organosilicons with two different substituents (diagram). These nanoparticles — named after the two-faced Roman…
Last month, AVA-CO2 AG (Zug, Switzerland; www.ava-co2.com) started up a pilot plant to further develop its AVA cleanphos process. The process recovers valuable phosphorus from “biocoal,” which is being produced from municipal wastewater sewage sludge through the company’s patented hydrothermal…
The research group of professor Shiro Saka at the Dept. of Socio-Environmental Energy Science, Graduate School of Energy Science, Kyoto University (Kyoto, Japan; www.ecs.energy.kyoto-u.ac.jp) has developed a new process that efficiently produces bioethanol from non-edible lignocellulose resources, without generating carbon…
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…
Last month, Clariant AG (Muttenz, Switzerland; www.clariant.com) said that the pilot plant of a new process for making substitute natural gas (SNG) has been successfully tested, signifying that the technology is ready for commercial application. The process, called Vesta Once-through…
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…
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,…
