source:EurekAlertAn electrochemical approach developed at KAUST produces molecular-sieving membranes that could enable a cheap energy-efficient separation of light hydrocarbons, such as olefins and paraffins. This separation, critical for the petrochemical industry, usually relies on extremely energy-intensive processes, such as distillation.Membrane-based strategies have emerged as promising alternatives to heat-driven separation approaches. Existing polymer-based membranes are not selective enough for hydrocarbon separation and also undergo plasticization, a structural change that alters the...

Hard Single-Molecule Magnets for Data Storage: Tetranuclear Rare Earth Metal Complexes With Giant Spin source:SciTechDailyMagnets formed from a single molecule are of particular interest in data storage, since the ability to store a bit on every molecule could vastly increase the storage capacity of computers. Researchers have now developed a new molecular system with a particular magnetic hardness. The ingredients in this special recipe are rare earth metals and an unusual nitrogen-based molecular bridge, as shown in the study published in the journal Angewandte Chemie.The suitability of...
