A new carbon-utilization technology developed by SeeO2 Energy Inc. (Calgary, Alta., Canada; www.seeo2energy.com) takes advantage of thermodynamics in a high-temperature electrolyzer to efficiently convert carbon dioxide into CO and O2 with 100% selectivity. Based on the principle of a reversible…
Phenolic compounds, such as chloro- and nitrophenols, are potentially hazardous when found in soils and the workplace. Normally, such compounds are detected with techniques such as mass spectrometry. There are several mechanisms for degrading and detoxifying contaminants: bacteria use specialized…
Sewage and wastewater often contain pollutants and environmental hormones (endocrine disruptors) that can have a negative effect on the environment and on human health. Catalysts currently used to destroy such pollutants involve high costs. And up to now, research has…
Natural wax coating Researchers from Aalto University (Finland; www.aalto.fi) have developed a new way of making garments water-resistant, without using toxic chemicals. The treatment is non-toxic, and does not impair breathability. The coating uses carnauba wax from Brazilian palm-tree leaves.…
Researchers at the City University of New York Energy Institute (ccny.cuny.edu) have developed a low-cost battery based on manganese dioxide and zinc that reaches voltages of greater than 2 V, a first-time achievement that could allow batteries with these low-cost…
On September 19, Focus-On (Dordrecht, the Netherlands; www.focus-on-process.com) — a new, 50:50 joint-venture (JV) of Samson AG (Frankfurt am Main; www.samson.de) and Krohne GmbH & Co. KG (Duisburg, both Germany; www.krohne.com) — introduced its new “intelligent process node,” a device…
Scientists at Nanyang Technological University (NTU; Singapore; www.ntu.edu.sg) have developed a device for atmospheric monitoring that can identify a wide range of airborne gases and chemicals instantly. The prototype device is portable and suitable for rapid deployment by agencies to…
A process for in-situ oxidation of hydrocarbons in low-quality oilfields, and subsequent gas separation, offers a path to generating hydrogen for fuel and chemicals that avoids any greenhouse gas emissions. Known as Hygienic Earth Energy (HEE), the process has been…
Electrochemical reduction of carbon dioxide to hydrocarbons and oxygenates on copper involves reduction to a carbon monoxide adsorbate followed by transformation to hydrocarbons and oxygenates. To ensure the sustainability of the process, the electrochemical CO2 reduction is typically conducted in…
High-pressure liquid chromatography (HPLC) using a chiral stationary phase (CSP) is the most effective method for separating enantiomers of chiral molecules. However, the limited number of CSPs available puts a constraint on applying this technology universally. Now, researchers from the…
