Summary: Researchers have discovered that lattice distortion in iodide/bromide mixed perovskites can suppress phase segregation, leading to increased ion-migration energy barrier. By using an approximately 2.0-electron-volt rubidium/caesium mixed-cation inorganic perovskite with large lattice distortion, they achieved an efficiency of 24.3% in all-perovskite triple-junction solar cells. This is the first reported certified efficiency for perovskite-based triple-junction solar cells.

Summary: This study presents the follow-up observations of the long-duration gamma-ray burst GRB210731A and reveals its unusual optical evolution. Theoretical modeling based on the synchrotron forward shock model suggests that energy injection and kinetic energy increase explain the subsequent light curve. Additionally, the results provide clues about the origin of GRB210731A.

Summary: A new lux-biosensor based on Bacillus subtilis was developed for detecting DNA-tropic and oxidative stress-causing agents. The biosensors showed increased sensitivity to certain toxicants compared to E. coli-based lux-biosensors. They can be used for studying mechanisms of toxicity against different types of bacteria.

Summary: Lanthanide-doped upconversion nanoparticles (UCNPs) with Yb3+ and Er3+ codoping and CaF2 shell were synthesized. Compared with homogeneous shell UCNPs, these heterogeneous core@shell UCNPs exhibited stronger upconversion luminescence. The UCNPs with CaF2 shells showed higher sensitivity to temperature in the range of 200-300 K, with a maximum thermal sensitivity of 2.2% K-1.

Summary: Experimental studies have shown that the fracture toughness of rocks increases with the confining pressure. The burst experiment is a widely used method to quantify this relationship. However, traditional interpretations of the critical pressure in this experiment may lead to overestimation of fracture toughness. This study proposes modifications to the experimental design to improve the consistency of results and supports the claim with acoustic emission recordings.

Summary: Nanotechnology, specifically the use of zinc oxide nanoparticles (ZnO-NPs), has shown promising results in reducing cadmium (Cd) toxicity in tomato plants by enhancing growth, photosynthesis, antioxidant system, and protein content. The upregulation of antioxidative enzymes by ZnO-NPs helps protect plants from oxidative stress induced by Cd, ultimately leading to improved plant growth and physiological parameters. This study suggests that ZnO-NPs can be a beneficial tool in mitigating heavy metal toxicity in plants.

Summary: The time of flight delay in the supernova neutrino signal is a unique tool for setting model-independent constraints on the absolute neutrino mass. We derive a new mass sensitivity achievable at the future DUNE far detector from a future supernova collapse in our galactic neighborhood, finding a sub-eV reach under favorable scenarios. These values are competitive with those expected for laboratory direct neutrino mass searches.

Summary: Lanthanide (Ln3+) luminescent materials with excellent optical properties play a crucial role in information security and data storage. The advances in dynamic colorful luminescent anti-counterfeiting nanomaterials enable high-level information encryption. This work demonstrates a superior triple-mode stimuli-responsive emission color modulation in a lanthanide-doped nanostructured luminescent material, which shows remarkable excitation wavelength/power-dependent color change and temperature-dependent color variation. The universal optical modulation and structural stability of the nanoparticles have advantages for anti-counterfeiting applications.

Summary: This study examined the effects of six pesticides commonly used in apple arboriculture on the functions of human monocyte-derived macrophages (hMDMs). The results showed that exposure to certain pesticides may have toxic effects on immune cells and modulate antioxidant enzyme expression, while other pesticides had minimal influence.

Summary: Neutrophil responses are crucial in inflammatory and infective events, but their dysregulation is linked to poor patient outcomes. Immunometabolism has provided insights into cellular functions in health and disease. This study presents optimized protocols for using XF analysis to probe glycolysis and oxidative burst in neutrophils and highlights the challenges of examining mitochondrial function using this technology. XF technology is a powerful platform with a user-friendly interface, but caution is advised when assessing neutrophil mitochondrial respiration.

Summary: The presence of extracellular iodoperoxidase (IPO) can activate the uptake of silicate-Si during an oxidative burst, and Si deposition is promoted in the presence of reactive oxygen species and phlorotannin. These findings suggest a mechanism where defense responses in kelp are facilitated by extracellular silicate-Si uptake.

Summary: We report a new fluorescent material with low cost, hypotoxicity, and concealment for anti-counterfeiting applications. The CsCu2I3@Cs3Cu2I5 composite exhibits triple-mode photoluminescence by adjusting excitation wavelengths due to multiple excited states of different phases. The composite shows broadband emission and high quantum yield from the self-trapped excitons effect of Cs3Cu2I5 and CsCu2I3 phases, and its stability is improved by incorporating polyethylene oxide. The composite only has slight decay in PL intensity and color coordinate after storage, and it maintains its initial PL intensity even after 200 hours of UV exposure.

Summary: Cr3+-doped Mg2SiO4 orthorhombic nanoparticles were synthesized using a combustion method, showing deep-red emission due to the 3d(3) electron configuration of the Cr3+ ion. The temperature-induced changes in emission from Cr3+-doped Mg2SiO4 were tested for ratiometric luminescence thermometry from cryogenic to physiologically relevant temperatures, with relative sensitivities of 0.7% K-1 for emission intensity, 0.8% K-1 for lifetime, and 0.85% K-1 for band position at 310 K.
