Summary: In this study, facile and homogenous undoped and Cr-doped SnO2 nanoparticles were successfully synthesized using an effective chemical assist sonochemical method. The structural, optical, and chemical behavior of the synthesized nanoparticles were examined using various characterization techniques. The results showed that the synthesized nanoparticles had high crystallinity, rutile phase, and uniform morphology. The optical band gap was found to increase with the addition of Cr, and the gas sensing characteristics of the nanoparticles were higher than reported in the literature.

Summary: The study investigated the bacterial inactivation of CeO2 nanoparticles synthesized by chemical co-precipitation and green synthesis methods, showing potential for bacterial cell death against Staphylococcus aureus and Escherichia coli strains. The green synthesis route using sweet basil leaf extract reduced the crystallite size of the CeO2 nanoparticles, demonstrating the formation of small-sized nanoparticles with agglomeration on the surface. X-ray diffraction analysis confirmed the face-centered cubic crystal system of the CeO2 nanoparticles.

Summary: A heptagonal isomerized bithiophene imide (iBTI) acceptor has been synthesized on a gram scale. Its derivatives with different substitution patterns can be obtained by controlling brominated sites. The torsion angle of the imide backbone depends on the number and rigidity of beta-substituted groups. The helical chirality of tetrasubstituted and [7]helicene-like derivatives based on iBTI shows promise for chiral semiconductor materials construction.

Summary: This study presents a defect analysis in Cd and Te inclusion regions within Bridgman-grown Cd0.95Mn0.05Te crystals for nuclear detectors. Contrary to Cd inclusions causing microcracks, Te inclusions do not generate defects but induce higher stresses. The higher stress from Te inclusions has a smaller impact on charge carrier transport in detectors compared to Cd inclusions, as confirmed by mu tau product measurements.

Summary: Introduction of photochromic properties into semiconductors allows for smart behaviors, color-related applications, and new modulation approaches. This study demonstrates that photoexcitation of the pi-aggregate of viologen cation radicals can efficiently trigger reverse electron transfer, leading to the discovery of the first single-component all-optically photochromic semiconductor. This discovery challenges the traditional concept that viologen compounds cannot undergo light-induced reverse reactions and offers a potential avenue for achieving all-optical switches in single-component photochromic smart semiconductors based on electron-transfer functional motifs.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
