The metal/semiconductor MoSH/MoSi2N4 contact forms a p-type Schottky contact with a small Schottky barrier. Furthermore, we found that the electronic structure and interfacial features of the MoSH/MoSi2N4 vdW heterostructure can be tuned under strain and electric fields.

Summary: Interface-driven effects in ferroelectric van der Waals (vdW) heterostructures have potential for alternative device architectures, but further research is needed in optical and multistate control. This study demonstrates electrical and optical control of ferroelectric polarization states in FeFETs made of ReS2/hBN/CuInP2S6 vdW materials. The polarization of the CuInP2S6 layer can be controlled by photoexciting the vdW heterostructure. Heterosynaptic plasticity is observed, emulating key synaptic functionalities with high accuracy. These findings pave the way for future research on photoferroelectric vdW systems and their applications in neuromorphic computing architectures.

Summary: Physical inactivity is a major risk factor for non-communicable diseases and early mortality. However, there is a lack of training on physical activity counseling in undergraduate medical education and postgraduate family medicine residency programs in Canada. The provision of structured physical activity counseling education to residents is limited, and there are no immediate plans to change the content or amount of teaching. There is a significant gap between the recommendations of the World Health Organization and the current curricular content and needs of family medicine residents. Developing online educational resources for physical activity prescription would be beneficial, according to most program directors.

Summary: This study focuses on utilizing monomer hydroxyethyl methacrylate, 2-carboxyethyl acrylate, initiator ammonium persulfate and cross-linker N ' N '-methylene bisacrylamide to create polymeric composites for the poorly water-soluble drug Letrozole (LTE) using free radical polymerization. The developed polymeric composites demonstrated increased swelling index and solubility compared to pure drug and beta-cyclodextrin-Letrozole complex. The findings suggest that these polymeric composites can be a safe and effective platform for enhancing solubility of poorly water-soluble drugs.

Summary: In this study, catalytic oxidation was used to investigate the desulfurization and de-ashing of low rank lignite coal. The results showed that catalyst loaded on activated carbon was more efficient. The sulfur and ash removal rates were high, while the heating value of the coal sample slightly declined due to surface oxidation. XRD analysis indicated that most of the mineral matter in coal was removed during oxidation.

Summary: This study aims to address wax deposition issues in crude oil production, storage, and transportation by preparing nanofluids with different concentrations of Fe-magnetic nanoparticles (Fe-MNPs). The nanofluids were used to monitor the wax appearance temperature (WAT) of model waxy oil samples, and it was found that the nanofluid with 5% Fe-MNPs had the most positive effect on reducing pour point. The results demonstrate that the nanofluid can decrease WAT, improve flowability, and potentially serve as a flow improver for real crude oils in industry.
