Self-powered γ-InSe/p-Si heterojunction for photodetection: exploring humidity and light intensity dependent photoresponse.

In this study, high-quality γ-InSe thin films were successfully deposited on p-Si substrates via the RF sputtering technique. Structural characterization using XRD and Raman spectroscopy confirmed the formation of the hexagonal γ-phase of InSe film. FESEM analysis revealed the presence of small, homogeneous, and well-defined grains in the prepared γ-InSe film.

Lead-Free CsAgBiCl Double Perovskite: Experimental and Theoretical Insights into the Self-Trapping for Optoelectronic Applications.

Lead-free double perovskites (DPs) will emerge as viable and environmentally safe substitutes for Pb-halide perovskites, demonstrating stability and nontoxicity if their optoelectronic property is greatly improved. Doping has been experimentally validated as a powerful tool for enhancing optoelectronic properties and concurrently reducing the defect state density in DP materials. Fundamental understanding of the optical properties of DPs, particularly the self-trapped exciton (STEs) dynamics, plays a critical role in a range of optoelectronic applications.

Differential contributions of double-strand break repair pathways to DNA rearrangements following the irradiation of Arabidopsis seeds and seedlings with ion beams.

DNA rearrangements, including inversions, translocations, and large insertions/deletions (indels), are crucial for crop evolution, domestication, and improvement. The rearrangements are frequently induced by ion beams via the mis-repair of DNA double-strand breaks (DSBs). Unfortunately, how ion beam-induced DSBs are repaired has not been comprehensively analyzed and the mechanisms underlying DNA rearrangements remain unclear.

Aurantiochytrium mutant strains exhibiting different colony colors altered the contents of squalene.

Aurantiochytrium sp. 18W-13a, a marine heterotrophic protist belonging to the genus thraustochytrid, is known to accumulate high levels of squalene and carotenoids. Nowadays, the mutagenesis breeding of microorganisms is still widely practiced because the induced mutations of DNA do not involve the permanent integration of heterologous DNA sequences.
