Molecular Brass

Brass has been known to man since prehistoric times; now scientists in Germany have isolated the first molecular example of the copper–zinc alloy.

The chemistry of solid state alloys is well established, yet understanding why different alloys possess particular properties is a greater challenge. Using a bottom-up approach, scientists aim to build intermetallic materials from the smallest available components, and identify boundaries where molecular properties meet bulk material properties. Constructing molecular clusters which mimic such materials is a step in this direction, providing fundamental insights into the chemical bonding of the target materials.

Separation by levitation

 A team in the US has shown that enantiopure and racemic crystals can be separated by magnetic levitation.

The isolation of pure enantiomers is of particular importance in the pharmaceutical industry, where one enantiomer is typically responsible for the therapeutic effects of a drug, while the other may be inactive or even toxic. One alternative to the often used solution-based separation techniques such as high-performance liquid chromatography (HPLC) is to purify the desired enantiomer from a mixture of crystals of enantiomerically pure and racemic compound.

Dual warhead kills and disarms bacteria

A compound that kills bacteria and cleaves their DNA to prevent them passing on drug-resistant genes has been designed by researchers in India.

The increasing ineffectiveness of antibiotics and the absence of suitable new ones are problems long recognised by the medical community. Bacteria can mutate and adapt to become resistant so the stock of effective antibiotics is diminishing. In a recent report, the UK’s Chief Medical Officer stated that increasingly resistant microbes represent a global threat that in the next 20 years could see many more deaths associated with what were routine and safe surgeries.
