Paclitaxel (PTX) and anastrozole (ANA) have been frequently applied in breast cancer treatment. PTX is well-known for its anti-proliferative effect meanwhile ANA has just been discovered to act as an estrogen receptor α (ERα) ligand. The combination therapy of PTX and ANA is expected to improve treating efficiency, as ANA would act as a ligand binding with the ERα gene expressed in breast cancer cells and thereafter PTX would inhibit the division and cause death to those cancer cells. In this study, liposome-based nanocarriers (LP) were developed for co-encapsulation of PTX and ANA to improve the efficacy of the combined drugs in an Estrogen receptor-responsive breast cancer study. PTX-ANA co-loaded LP was prepared using thin lipid film hydration method and was characterized for morphology, size, zeta potential, drug encapsulation and in vitro drug release. In addition, cell proliferation (WST assay) and IN Cell Analyzer were used for in vitro cytotoxicity studies on a human breast cancer cell line (MCF-7). Results showed that the prepared LP and PTX-ANA-LP had spherical vesicles, with a mean particle size of 170.1 ± 13.5 nm and 189.0 ± 22.1 nm, respectively. Controlled and sustained releases were achieved at 72 h for both of the loaded drugs. The in vitro cytotoxicity study found that the combined drugs showed higher toxicity than each single drug separately. These results suggested a new approach to breast cancer treatment, consisting of the combination therapy of PTX and ANA in liposomes based on ER response.

This paper presents the results of research on making materials to adsorb toxic acidic gases, organic substances from Tra Bac coconut shell activated carbon, and combined with chemical treatment on the laboratory scale. Methods were used for this study consisting of SEM, EDS; BET, and DPC5 (kinetic adsorbent). The results showed that the fabricated filter material has a surface area of 664 m2/g, calculated according to BET, has a protection time with benzene vapor (L= 5 cm, Co(vapor) = 18 mg/L) of 56 minutes; protection time with HCl acid vapor (L= 5 cm, Co (vapor) = 1.1 mg/L) is 280 minutes. The results of the study have exhibited a good ability to filter benzene vapor and HCl vapor. This material has the potential for use in the manufacture of personal respiratory protective equipment.

This study investigates the material composition and structural characteristics of tubular positive electrodes in high-capacity lead–acid batteries, combining experimental analysis with theoretical design calculations. Advanced characterization techniques, including X-ray diffraction (XRD), scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM–EDS), and infrared (IR) spectroscopy, were employed to identify phase composition, elemental constituents, and organic additives. Results indicate that the positive active mass primarily consists of tetragonal PbO₂ with minor orthorhombic PbSO₄, along with carbonaceous and polymeric conductive additives. The tubular sheath was found to be a polyester-based composite containing ester, alcohol, and anhydride functional groups, with silica-derived Si–O–Si structures. SEM analysis revealed a highly porous fine-particle morphology, suitable for binder-free filling into tubular casings. Computational design determined key structural and mass parameters of the positive active material (PAM), leading to an optimized electrode configuration with a theoretical battery capacity of 17,189 Ah. These findings provide a scientific basis for the domestic production of high-performance tubular lead–acid batteries.

This study investigates the effects of deposition temperature, number of deposition cycles, and cobalt (Co) additives on the structural and electrochemical properties of the positive active material in nickel–cadmium (Ni–Cd) batteries. The purpose is to optimize fabrication parameters to enhance material utilization efficiency and battery performance. Electrodes were fabricated by impregnating porous nickel substrates with nickel nitrate solution, followed by chemical conversion in potassium hydroxide under varying temperatures (65 – 80 °C) and repeated for different cycle numbers (1 – 5). A cobalt nitrate post-treatment was applied to selected samples. Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), and hydrostatic weighing methods were employed to characterize microstructure, composition, density, and porosity. Charge–discharge performance was evaluated using prototype Ni–Cd cells. Results show that the optimal deposition temperature range is 70 – 75 °C, which promotes uniform active material distribution and high density while maintaining sufficient porosity. Four deposition cycles yielded the best balance between mass loading and structural stability. The addition of cobalt improved utilization efficiency by approximately 5.2% and reduced internal resistance from 7.15 mΩ to 4.85 mΩ. These findings provide a scientific basis for improving Ni–Cd electrode fabrication, and future studies may explore long-term cycling behavior and alternative conductive additives.

In this study, SiO₂/CaCl₂ composite materials were synthesized via a sol–gel method for atmospheric water harvesting applications. The effects of the SiO₂/CaCl₂ mass ratio and gel aging time on structural characteristics and adsorption performance were systematically investigated. The optimal synthesis conditions were identified at a SiO₂/CaCl₂ mass ratio of 1:1 with a gel aging time of 48 h. Structural properties of the synthesized composites were characterized using SEM–EDX, X-ray diffraction (XRD), and N₂ adsorption–desorption (BET) analysis. The results revealed a biphasic structure consisting of crystalline CaCl₂ dispersed within an amorphous SiO₂ matrix, with a specific surface area of 19.1 m² g⁻¹ and mesoporous characteristics. At room temperature (25–27 °C), the composite exhibited water adsorption capacities of 0.31 g g⁻¹ at 70% relative humidity (RH) and 0.39 g g⁻¹ at 90% RH, reaching equilibrium after approximately 60 h. Although a decrease in adsorption capacity was observed after thermal regeneration, the material retained considerable water uptake, demonstrating its potential for low-cost, decentralized atmospheric water-harvesting systems.
