Hot paper: Using computational chemistry to predict the thermodynamic and electronic properties of tunable II–VI and IV–VI semiconductor based MOFs

Metal-organic frameworks (MOFs) are a class of well-known crystalline compounds at the bridge of organic and inorganic chemistry. MOFs have many potential applications such as in gas storage and catalysis. They also have potential applications as semiconductors in photovoltaics, photo-emitters and transistors.

In this hot paper, researchers from the University of Bath, UK use DFT calculations to predict novel hybrid MOFs with desirable semiconductor properties. They expand on the ubiquitous II-VI and IV-VI semiconductors (e.g. CdS, ZnSe, PbTe) and investigate their corresponding hybrid organic-inorganic analogues based on the archetype 3D framework of Pb3(C6S6). Five hybrids were found to be of interest because they have a negative formation enthalpy and band gaps predicted to be in the visible light spectrum. Thus, these five hybrids may have applications as photo-active materials.

Hot paper: Feature article of soft X-ray characterisation of organic semiconductor films

This Feature Article by McNeill and Ade reviews the characterisation of the structural composition and morphology of thin film organic semiconductors using different X-ray techniques. The authors discuss six different applications of soft X-rays including scanning transmission X-ray microscopy (STXM); resonant X-ray scattering; resonant X-ray reflectivity; near-edge X-ray absorption fine-structure spectroscopy; polarized STXM and polarized soft X-ray scattering. The authors conclude that soft X-ray techniques have great potential for unravelling the complex structures shown by organic semiconductor blends and multilayers.

Hot paper: Layer-by-layer coating of alginate matrices with chitosan–alginate

It is postulated that probiotic bacteria play a role in maintaining good health and they have been shown to alleviate the symptoms of some common conditions such as traveller’s diarrhoea. If the bacteria are to be ingested orally, they must withstand an acid challenge in the stomach before they can reach the intestine to act. A common strategy to reduce bacterial cell death is encapsulation, usually using a polymer matrix. The naturally occurring polysaccharide alginate is the most popular probiotic encapsulation-based material.

In this hot paper, Khutoryanskiy, Charalampopoulos and co-workers evaluate the production of alginate matrices coated with multilayers of alternating alginate and chitosan as viable encapsulation materials for probiotic bacteria. The authors show, that the multilayers are stable in both simulated gastric and intestinal solutions, with encapsulation in 3-layer coated matrices giving the highest recovery of viable cells. It is suggested that this method of encapsulation could be used to protect orally administrated probiotics from the low pH of the stomach.
