TL;DR: In this article, the authors explored the frustration of chiral ordering in cholesteric liquid crystal droplets with planar degenerate anchoring using numerical modeling and found that the half-diameter +2 disclination from previous studies is in fact a double-helix of two λ+1 disclination lines.
Abstract: Frustration of chiral ordering is explored in cholesteric liquid crystal droplets with planar degenerate anchoring using numerical modeling. Droplets of variable pitches are studied, demonstrating the role of a gradually increasing cholesteric pitch and the corresponding equilibrium structures. All previously known structures are identified but with notable differences. The structures presented with director fields are complemented with a detailed description of the defect regions. The characteristic half-diameter +2 disclination from previous studies is found to be in fact a double-helix of two λ+1 disclination lines, whereas the full-diameter +1 disclination is composed of an alternating series of τ−1/2 and λ+1/2 disclination rings. Finally, two new meta-stable cholesteric structures -Lyre and Yeti- are found, which are characterised by complex compositions of cholesteric disclinations.

TL;DR: Whereas OPFR values were higher in sediments, similar concentrations (in the Evrotas) and even lower concentrations than HFRs (Sava) were found for OPFRs in the fish samples, indicating the lower bioaccumulation potential of OP FRs.

TL;DR: Determination of LMP in a cell model system is methodologically challenging and it is difficult to prove that LMP is the primary event leading to cell death, but it may prove to be a valuable approach in therapy, either as a trigger of cell death or as a mechanism of therapeutic drug release in the case of delivery systems that target the endocytic pathway.

TL;DR: It was found that upon dental grinding and sandblasting, the surface of the material was heavily damaged in part plastically deformed, but the amount of transformed monoclinic zirconia was low, implying that stress-assisted corrosion plays an important role in the fatigue behavior of dental zIRconia.
Abstract: This study was designed to evaluate the effects of dental grinding and sandblasting on the ageing and fatigue behavior of pressureless-sintered biomedical grade Y-TZP ceramic. It was found that upon dental grinding and sandblasting, the surface of the material was heavily damaged in part plastically deformed, but the amount of transformed monoclinic zirconia was low. The partitioned tetragonal zirconia grains and pre-existing monoclinic zirconia in the ground and sandblasted surfaces hindered the propagation of the diffusion-controlled transformation during subsequent ageing. Dental grinding at a high rotation speed lowered the mean strength under static loading and the survival rate under cyclic loading. Sandblasting, in contrast, resulted in surface strengthening and substantially higher survival rate under cyclic loading. For all tested groups, about 10–15% lower survival-strength values were obtained when tested in artificial saliva, compared to dry specimens, implying that stress-assisted corrosion plays an important role in the fatigue behavior of dental zirconia.
