Transient MRI changes and neurological deterioration in glioblastoma upon SARS-CoV-2 infection.

Purpose: Little is known about the effect of SARS-CoV-2 infection on glioblastoma (GBM) growth, metabolism, and prognosis. Immunological changes within GBM tissue are potentially symptomatic, underlining the urgent need for a better understanding of this phenomenon. To date, the complex underlying biology has not been fully elucidated.

: a tool for the investigation of elasto-plastic behaviour on polycrystalline samples using X-ray and neutron diffraction.

The software is designed to analyse diffraction data from loading experiments on polycrystalline samples for the determination of single-crystal elastic constants (SECs) and elasto-plastic self-consistent (EPSC) modelling of lattice strains. The SECs can be obtained from powder-diffraction elastic constants using a variety of grain-to-grain interaction models, namely Voigt, Reuss, Hill, Kröner, de Wit and Matthies approaches. The texture of the polycrystalline sample can be taken into account using the orientation distribution function of the grains.

Potassium Ion Conductivity in the Cubic Labyrinth of a Piezoelectric, Antiferromagnetic Oxoferrate(III) Tellurate(VI).

Orange-colored crystals of the oxoferrate tellurate K Fe Te O [x=0.222(4)] were synthesized in a potassium hydroxide hydroflux with a molar water-base ratio n(H O)/n(KOH) of 1.5 starting from Fe(NO )  ⋅ 9H O, TeO and H O at about 200 °C.

Redox Chemistry and Reversible Structural Changes in Rhombohedral VOF Cathode during Li Intercalation.

Metal oxyfluorides are currently attracting much attention for next-generation rechargeable batteries because of their high theoretical capacity and resulting high energy density. Rhombohedral VOF is promising because it allows two-electron transfer during electrochemical lithium cycling, with a theoretical capacity of 526 mAh g. However, the chemical changes it undergoes during operation are not clearly understood.

Diffraction-based determination of single-crystal elastic constants of polycrystalline titanium alloys.

Single-crystal elastic constants have been derived by lattice strain measurements using neutron diffraction on polycrystalline Ti-6Al-4V, Ti-6Al-2Sn-4Zr-6Mo and Ti-3Al-8V-6Cr-4Zr-4Mo alloy samples. A variety of model approximations for the grain-to-grain interactions, namely approaches by Voigt, Reuss, Hill, Kroener, de Wit and Matthies, including texture weightings, have been applied and compared. A load-transfer approach for multiphase alloys was also implemented and the results are compared with single-phase data.
