The enteric bacterium Escherichia coli is the most extensively used prokaryotic organism for production of proteins of therapeutic or commercial interest. However, it is common that heterologous over-expressed recombinant proteins fail to properly fold resulting in formation of insoluble aggregates known as inclusion bodies. Complex systems have been developed that employ simultaneous over-expr...

[1] Atmospheric deposition of mineral dust supplies much of the essential nutrient iron to the ocean. Presumably only the readily soluble fraction is available for biological uptake. Previous ocean models assumed this fraction was constant. Here the variable solubility of Fe in aerosols and precipitation is parameterized with a two-step mechanism, the development of a sulfate coating followed b...

Abstract The search for truly quantum phases of matter is a center piece modern research in condensed physics. Quantum spin liquids, which host large amounts entanglement—an entirely feature where one part system cannot be measured without modifying the rest—are exemplars such phases. Here, we devise realistic model relies upon well-known Haldane chain phase, i.e. phase spin-1 chains fractional...

Morin dye is known as a cheap and readily available selective ‘off → on’ fluorescent sensitiser when immobilised in phase transfer membrane for the detection of Al3+ ions. Here, morin derivative, NaMSA, which dissolves water with good long-term stability used conjunction fibre-optic transducer lock-in to detect drinking below potability limit. The combination water-soluble require neither prepa...
