Nitrile compounds (R–N≡N) are important for the manufacturing of fragrances, pharmaceuticals, superglue and chemical-resistant gloves. Currently, such nitrile compounds require the use of highly toxic cyanide in their synthesis. Now, an alternative cyanide-free chemo-enzymatic cascade process is being developed by…
In 1851, the year that the first America’s Cup sailboat race was contested, the top speed for a wind-powered vessel was 10 knots. Over the next 100 years, top sailboat speeds barely budged, but by the mid-1970s, top sailing speed…
