Summary: This study presents a novel method to enhance the photovoltaic and photoelectric properties of the Cs/MA/FA PSK layer. By incorporating nanoscale praseodymium and neodymium ions as B-site dopants, the crystallinity is improved, the charge-recombination process is prolonged, and light harvesting is increased, leading to higher efficiency. In addition, the use of inorganic copper indium sulfide as a hole-transport layer instead of spiro-OMeTAD reduces production costs and enhances device stability.

Summary: In this study, the simulation of magnetic nanoparticle hyperthermia on a 3D tumor model constructed based on a CT image of a tumor was conducted. Results showed that temperature profiles near the injection points were not similar due to the presence of blood capillaries. Investigation on the effects of using dissimilar injection parameters revealed that it can achieve a higher damage fraction of tumor cells, but the asynchronous injections strategy does not lead to significant improvements in tumor damage or temperature distribution uniformity.

Summary: The hydrophobicity and low permeability issues of nanofiltration (NF) membranes were addressed by modifying polyvinyl chloride (PVC) membranes with iron (III) oxide@Gum Arabic (Fe3O4@GA) nanocomposite. The addition of 0.25 wt% Fe3O4@GA/PVC membrane significantly improved the removal of organic contaminants with high rejection rates. Thus, incorporating Fe3O4@GA nanocomposite into the membrane casting solution is an effective approach for modifying NF membranes.

Summary: During drug release, the drug is transferred through the drug delivery system to the surface and then to the release medium. Metal-organic frameworks (MOFs) have unique features, such as suitable pore size, high surface area, and structural flexibility, making them promising carriers for drug delivery. The loading and release of therapeutic drugs through MOFs are achieved effectively due to the tunable inorganic clusters and organic ligands. A quantitative structure-property relationship (QSPR) method utilizing structure-based descriptors and a best multilinear regression (BMLR) model accurately predicts the drug release rate from MOFs. The model demonstrates high accuracy and precision through validation with external observations.
