A 3-D printed polymer with enzymes turns methane to methanol

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 —…

Recycling waste polystyrene into membranes

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,…

Fuel-cell-based carbon capture system can augment power generation

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,…

A glass for all colors

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…

Imitating cactus plants to improve membrane performance

Regulation of water content in polymeric membranes is important in several applications, including proton-exchange fuel cell membranes. Normally, this is achieved either by external regulation or by operating the cells at higher temperatures. Now a team from CSIRO (Melbourne, Australia;…

Commercial launch for a hybrid wastewater-treatment process

A hybrid process that combines micro-flotation and flat-sheet ceramic-membrane filtration to remove oil and suspended solids from difficult-to-treat industrial wastewater has been commercialized by akvola Technologies (Berlin, Germany; www.akvola.com). The system can treat water with high oil loads (up to…
