A poison helps to understand H2-producing biocatalysts
The toxic cyanide molecule attacks H2-generating enzymes, but at the same time provides new insights into catalysis
20-Dec-2022
In nature, enzymes termed hydrogenases are capable of producing molecular hydrogen (H2). Special types of these biocatalysts, so-called [FeFe]-hydrogenases, are extremely efficient and therefore of interest for biobased hydrogen production. Although scientists have learned a lot about how these ...
Gold from old phones is real prospect thanks to chemical advance
02-Sep-2016
Vast quantities of gold could be salvaged from old mobile phones using a simple chemical method, a study shows. Current methods for extracting gold from old gadgets are inefficient and can be hazardous to health, as they often use toxic chemicals such as cyanide, researchers say. Electrical waste ...
Highly efficient heavy metal ions filter
27-Jan-2016
ETH researchers have developed a new water filtration system that is superior to existing systems in many respects: it is extremely efficient at removing various toxic heavy metal ions and radioactive substances from water and can even be used in gold recovery. In November, Brazil experienced an ...
New data from a BfR human study: no cyanide risk resulting from the consumption of marzipan and persipan
13-Mar-2015
A human study conducted by the Federal Institute for Risk Assessment (BfR) enables more differentiated risk assessment of cyanide exposure following the consumption of bitter apricot kernels, persipan, linseed or manioc (cassava). The study results have now been published in “Archives of ...
Taming a poison
Saving plants from cyanide with carbon dioxide
07-Apr-2014
The scientific world is one step closer to understanding how nature uses carbon-capture to tame poisons, thanks to a recent discovery of cyanoformate by researchers at Saint Mary's University (Halifax, Canada) and the University of Jyväskylä (Finland). This simple ion — which is formed when ...
Unique chemistry in hydrogen catalysts
28-Oct-2013
Making hydrogen easily and cheaply is a dream goal for clean, sustainable energy. Bacteria have been doing exactly that for billions of years, and now chemists at the University of California, Davis, and Stanford University are revealing how they do it, and perhaps opening ways to imitate them. A ...
Dionex Announces EPA Federal Register Approval of Ion Chromatography for Total Cyanide Analysis
26-Oct-2010
The United States Environmental Protection Agency (EPA) is proposing to add new and revised methods published by the EPA, voluntary consensus organizations such as ASTM International, and other commercial entities, for use in water quality monitoring. These changes and additional methods will ...
Accidental discovery produces durable new blue pigment for multiple applications
18-Nov-2009
An accidental discovery in a laboratory at Oregon State University has apparently solved a quest that over thousands of years has absorbed the energies of ancient Egyptians, the Han dynasty in China, Mayan cultures and more – the creation of a near-perfect blue pigment. Through much of recorded ...
Designer molecule detects tiny amounts of cyanide, then glows
26-Oct-2009
A small molecule designed to detect cyanide in water samples works quickly, is easy to use, and glows under ultraviolet or "black" light. Although the fluorescent molecule is not yet ready for market, its Indiana University Bloomington creators report in the Journal of the American Chemical ...
CyPlus commissions Cold Caro’s Acid Systems at Two of Jaguar Mining Inc.’s Sites in Brazil
09-Sep-2009
CyPlus® has succeeded in commissioning two Cold Caro’s Acid systems for Concord, New Hampshire, USA-based Jaguar Mining Inc. at their Turmalina and Paciencia gold-mining operations in Brazil. The systems treat cyanide-containing effluent. Cold Caro’s Acid is a powerful oxidant that is produced in ...
