Summary: This work reports a chemically robust yellow emissive one-dimensional (1D) semiconductor, silver 2,6-difluorophenylselenolate-AgSePhF2(2,6), which belongs to the class of hybrid low-dimensional semiconductors. Introduction of fluorine atoms at the (2,6) position of the phenyl ring induces a structural transition from 2D sheets to 1D chains. AgSePhF2(2,6) exhibits strongly dispersive conduction and valence bands along the 1D crystal axis. Visible photoluminescence with prompt and delayed components is observed at room temperature.

Summary: The effect of adding nano-sized arc stabilizing materials on fume emissions and solubility characteristics is discussed in this study. Sodium/potassium titanates of micro and nano sizes were used as substitutes for conventional sodium and potassium silicate compounds in SMAW electrode flux. The newly developed electrodes showed significant reductions in soluble fractions of fumes, with a 50% reduction observed with micro-sized potassium titanate compounds and a further 60% reduction when nano-sodium titanate was added. The inclusion of nano-sized sodium titanate also resulted in reduced fume formation rates and breathing zone concentrations compared to conventional sodium silicate coated electrodes.

Summary: This study explored the influence of thermal activation and particle size on cementitious activity of bauxite tailings. It was found that at 500 degrees Celsius, the main mineral phases of the tailings began to undergo structural changes, converting into other mineral phases. Further raising the temperature to 600 and 700 degrees Celsius resulted in the complete removal of hydroxyl groups in both types of tailings. Additionally, the activation temperature also affected the particle size of the tailings, with an increase observed when the temperature exceeded 700 degrees Celsius. Moreover, finer tailings exhibited higher activity index, and at the same activation temperature, FBT showed higher pozzolanic activity compared to CBT.

Summary: In this study, the influence of sonication on the reactive precipitation of ammonium uranyl carbonate (AUC) was investigated. It was found that sonication increases precipitation kinetics, modifies crystal morphology, decreases particle size, and produces powders with more surface area. Sonication also leads to more uniform and regular crystals compared to silent conditions, and results in a more crystalline powder of AUC. This sonochemical technique shows improved quality of AUC precipitates in terms of physical morphology, surface area, crystallinity, and homogeneity.

Summary: Plants exposed to suboptimal environmental conditions often have reduced crop yields, but pre-exposure to mild stress can prepare plants for subsequent challenges. This study investigated the effects of herbicide sub-doses on oxidative stress caused by waterlogging and the potential for waterlogging to mitigate herbicide injury in soybean crops. The results showed that early exposure to a sub-dose of oxyfluorfen enhanced the plants' ability to tolerate waterlogging, while pre-treatment with the herbicide paraquat did not have significant effects. Additionally, pre-exposure to waterlogging reduced the damage caused by herbicides, suggesting the existence of cross-tolerance between herbicides and waterlogging in soybean plants.

Summary: The effects of multiwall carbon nanotubes (MWCNTs) on the electrical, dielectric, and piezoelectric properties of the ferroelectric ceramic/castor-oil polyurethane (PUR) composite films were investigated. The addition of MWCNTs significantly enhanced the electrical and piezoelectric properties of the composite films by acting as conductive bridges between the lead zirconate titanate (PZT) particles. The dispersion of MWCNT nanoparticles also improved the poling effectiveness and increased the d(33) coefficient of the three-phase piezoelectric composites.

Summary: In this study, Nb2O5 inserted with Fe was synthesized using the microwave-assisted hydrothermal method. The insertion of Fe promoted the formation of pores and decreased the band gap of Nb2O5. The 1%Fe-Nb2O5 sample showed the best photocatalytic discoloration result. The increase in ion concentration led to a decrease in photocatalytic performance. The factorial design experiment revealed the significant effects of catalyst type, catalyst dosage, pH, and reaction time on the degradation of RhB.

Summary: NaPO3-20Ga(2)O(3)-xNa(2)WO(4) (x = 0, 1, 3, 5 and 10% mol) tungsten gallium-phosphate glasses were synthesized and evaluated as potential intrinsic glass scintillators due to their high chemical stability and excellent optical properties. Increasing Na2WO4 content led to a decrease in OH- groups and the presence of sole W6+ species. The glasses exhibited high transmittance (around 90%) over a wide spectral range (400 to 2500 nm) and luminescence emission characteristic of the WO42- complex with average lifetimes ranging from 32 to 20 μs. Cryogenic temperatures resulted in a significant increase in luminescence emission for the NaPGaW glasses.

Summary: Conventional systemic drug delivery methods are less effective compared to localized delivery systems. This study developed thermoresponsive nanocomposites based on poly(N-vinylcaprolactam) and silica particles for efficient and controlled release of hydrophobic and hydrophilic drugs. The nanocomposites exhibited improved rheological properties and prevented diffusion away from the injection site. The synthesized materials achieved controlled drug release for 7 days and showed promising inhibitory effects on carcinoma cells while being non-toxic to healthy cells.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
