Abstract: Using a method based on the measurement of below-threshold cavity loss and optical power, we experimentally determine the spontaneous emission factor of 850 nm gain-guided vertical-cavity surface-emitting lasers. Since our method needs only below-threshold information, we can avoid complex problems concerning above-threshold effects and obtain more reliable results. It is also pointed out that the typical L-I curve-fitting method results in unreliable estimation of the spontaneous emission factor. The values of spontaneous emission factors obtained are 6.6, 4.1, and 2.4 ×10 -4 for 10-, 15-, and 20-µm-diameter circular aperture VCSELs, respectively.

Abstract: We demonstrated that a well-designed nanopatterned cover improves photovoltaic efficiency across a wide range of incident angles ( θ ). A nanopatterned cover was created using an integrated ray-wave optics simulation to maximize the light absorption of the surface-textured Si photovoltaic device. A hexagonally arranged nanocone array with a 300 nm pitch was formed into a polymer using nanoimprinting, and the nanostructured polymer was then attached to a glass cover with an index-matching adhesive. Angle-resolved current density-voltage measurements on Si photovoltaic devices showed that the nanopatterned glass cover yielded a 2–13% enhancement in power conversion efficiency at θ = 0–60°, which accounted for its broadband antireflective feature. We performed all-season-perspective simulations based on the results of the integrated ray-wave optics simulations and solar altitude database of South Korea, which validated the sustainability of the developed nanopatterned cover during significant seasonal fluctuations.

Abstract: According to the Rietveld refinement, the perovskite-related Ba 2 CrTaO 6 was found to have a P 6 3 /mmc space group with lattice constants of a =5.7383(1) and c =18.7832(2) Å. The Cr and Ta ions are completely ordered; the face-shared octahedra are occupied by Cr ions and the corner-shared octahedra by Ta ions. The increased covalent bonding nature of (Cr-O-Cr) and/or (Cr-Cr) bonds via π(ε gπ - p π -ε gπ ) and σ( a 1g - a 1g ) would be the main driving force to stabilize the 8-layer hexagonal structure. The existence of such covalent bondings was confirmed by the ESR spectroscopic analysis and magnetic susceptibility measurement. The XANES spectra for Ta LIII-edge indicated that such a covalency induces a relatively weak covalency of competing (Ta-O) bond.

Abstract: The Committee of Clinical Practice Guidelines of the Korean Diabetes Association (KDA) updated the previous clinical practice guidelines for Korean adults with diabetes and prediabetes and published the seventh edition in May 2021. We performed a comprehensive systematic review of recent clinical trials and evidence that could be applicable in real-world practice and suitable for the Korean population. The guideline is provided for all healthcare providers including physicians, diabetes experts, and certified diabetes educators across the country who manage patients with diabetes or the individuals at the risk of developing diabetes mellitus. The recommendations for screening diabetes and glucose-lowering agents have been revised and updated. New sections for continuous glucose monitoring, insulin pump use, and non-alcoholic fatty liver disease in patients with diabetes mellitus have been added. The KDA recommends active vaccination for coronavirus disease 2019 in patients with diabetes during the pandemic. An abridgement that contains practical information for patient education and systematic management in the clinic was published separately.
