• Gold from old phones is real prospect thanks to chemical advance
  

  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 - more

• Highly efficient heavy metal ions filter
  

  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 unp more

• New data from a BfR human study: no cyanide risk resulting from the consumption of marzipan and persipan

  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 Toxicology” more

How Much Water Can Kill You?

You may have heard of deadly poisons like arsenic, cyanide and even the devilishly hard to detect polonium 210. But did you know even drinking water could kill you? We had Deborah Blum, Ph.D., author of the totally awesome book “The Poisoners Handbook,” explain how H2O can be deadly in the right ... more

The Chemistry of Poisons

The second in the series on poisons looks at cyanide, another notorious agent of murder. It’s played a role in genocide, in suicide pills, and is also found in small amounts in the seeds of numerous fruits. So, why is cyanide so poisonous, and why are deaths from cyanide poisoning less of a rarity t more

The Chemistry of Cherries

It’s cherry season, and the cherry trees are currently heaving under the weight of both sweet and sour cherries. Here we take a look at the chemical differences between the two, and why cherry stones are poisonous. more

• Redox-induced switch between luminescent and magnetic properties in a trinuclear cyanide-bridged compound

  A trinuclear cyanide-bridged luminescent compound trans-RuII(DMAP)4(CN)2[(PY5Me2)Mn]2[PF6]4 (1-R) and its oxidation product, ferromagnetic trans-RuIII(DMAP)4(CN)2[(PY5Me2)Mn]2-[PF6]5 (1-O) have been synthesized and fully characterized. This is the first example of molecular materials about redox-con more

• Compositional and Structural Insights into the Nature of the H-Cluster Precursor on HydF

  Assembly of an active [FeFe]-hydrogenase requires dedicated maturation enzymes that generate the active-site H-cluster: the radical SAM enzymes HydE and HydG synthesize the unusual non-protein ligands - carbon monoxide, cyanide, and dithiomethylamine - while the GTPase HydF serves as a scaffold for more

• Fluorogenic Naked-Eye Sensing and Live-Cell Imaging of Cyanide by Hydrazine-Functionalized CAU-10 Metal-Organic Framework

  A hydrazine-functionalized, highly stable Al(III) based metal-organic framework (MOF) with CAU-10 (CAU = Christian-Albrechts-University) framework topology namely CAU-10-N2H3 (1) was specifically designed to detect lethal CN− ion in aqueous medium. The MOF was characterized by X-ray powder diffracti more
