Summary: Acute hepatitis in children is a cause for concern. Successful global vaccination campaigns against hepatitis A and B viruses have led to significant improvements in public health. However, there are still other viruses that can cause liver damage in children, leading to severe illness with rapid elevation of liver enzymes.

Summary: A nanocomposite of polypyrrole@MCM-41 was prepared by polymerizing pyrrole inside silica nanopores, resulting in stable electrochemical activity at positive potentials. Characterization was done using various techniques, and the composite's electrochemical properties were compared with DFT calculations.

Summary: In this study, the decorated MCM-41 with iron and magnesium oxide (Fe/Mg-MCM-41) was found to be an excellent adsorbent for arsenic(V) removal from water, with high adsorption capacity, wide pH application range, and regenerability. The characterization analysis and experimental results confirmed the promising potential of Fe/Mg-4-MCM-41 as an adsorbent for treating As-contaminated wastewater.

Summary: As a widely studied mesoporous silica nanoparticle in drug delivery systems, MCM-41 possesses unique properties but its applications have not been industrialized due to its interaction with biomolecules, especially proteins. This study investigated the interactions between MCM-41 and proteins using BSA, Lyso, and BHb as model proteins. Different interaction patterns were observed, leading to varying effects on protein structure, MCM-41 surface chemistry, and protein adsorption capability.

Summary: The phenomenon of subpulse drifting is an important single-pulse phenomenon that can potentially provide important insights into the elusive radio emission mechanism in pulsars. We analyzed the frequency behavior of the single pulses of B0818-41 and compared it to the evolution of the average profile to determine the geometry of the pulsar emission beam. Our findings suggest that a circular carousel model is not consistent with the observed behavior, and we propose alternative elliptical carousel geometries.

Summary: This paper demonstrates a data-driven approach to determining modeling parameters for FRP-retrofitted RC columns in accordance with current standards and proposes parameters for flexure-dominated column behavior. A refined backbone curve is suggested for FRP-retrofitted columns, prescribing an incremental rotation capacity that takes into account the improved behavior of the retrofitted column. Modeling parameters for flexure-dominated columns are also proposed.

Summary: Our study aimed to investigate the ability of IL-41 to protect against CS-induced lung inflammation in vivo. The results showed that IL-41 pre-treatment alleviated pulmonary inflammatory infiltration and lung tissue lesions, limited CS-induced weight loss, and promoted the polarization of M2 macrophages. IL-41 also increased the levels of IL-10 and reduced the production of TNF-α, IL-6, and IL-1β.

Summary: The study investigates the adsorption behavior of oxygen, nitrogen, deuterium, and deuteriated methane gases into porous glass MCM-41 using neutron diffraction analysis and atomistic computer modeling. Results show that all four gases exhibit similar adsorption behaviors in MCM-41, with initial layering of liquid on the pores' surface followed by capillary condensation, leading to hexagonal lattice distortion in the pores.

Summary: We report the synthesis, characterization, and catalytic activity of a highly efficient and reusable silica-based catalyst MCM-41@CP@PAL@Cu. The catalyst was prepared by anchoring a Cu(II)-Schiff base complex onto mesoporous MCM-41 with a surface-grafted -chloro group. Various analytical methods, including FT-IR, Low angle P-XRD, TGA, N-2 adsorption-desorption, SEM, TEM, and MPAES, were used to characterize the obtained catalyst. The composition and chemical state of Cu metal in the catalyst were identified using X-ray photoelectron spectroscopy. The catalyst MCM-41@CP@PAL@Cu was employed for the conversion of various alkenes to their epoxides with a yield of 99% in the model reaction. The catalyst can be reused for at least six times.

Summary: This study investigated the hydrodesulfurization activity of NiMo catalysts supported on mesoporous MCM-41 type materials shaped with binder. Ion exchange with protons of Al- or Ti-substituted MCM-41 mesoporous supports was found to increase the efficiency of direct desulfurization. The NiMo/HTiMCM-41 catalyst exhibited the highest catalytic efficiency in the HDS of 4,6-DMDBT and the diesel oil fraction, attributed to its appropriate acidity and desirable metal-support interaction.

Summary: Researchers presented a (crypto) tephrochronological record from marine sediment cores in the Chilean continental margin around 41 degrees S, identifying cryptotephras and visible tephra layers from volcanic centers such as Hudson and Michinmahuida. The study provides insights into the eruptive history of these volcanoes in the Southern Volcanic Zone of the Andes, from pre-Holocene to Late Holocene periods.

Summary: While Zimbabwe has a relatively low percentage of older adults, research on aging focuses on social protection, health, and quality of life. However, inadequate social safety nets and funding issues contribute to increasing poverty and vulnerability among older adults. Although Zimbabwe has a framework for addressing aging, implementation is lacking and there is a lack of longitudinal data on aging.

Summary: This study develops a one-dimensional 43-qubit superconducting quantum processor called Chuang-tzu, which is used to simulate and characterize emergent topological states. The quantum processor is capable of capturing important topological features of quantum systems, providing a new method for studying quantum topological systems in the NISQ era.
