Rational design of advanced polar hosts with high sulfur loading, facilitated ionic/electronic transport and effectively suppressed shuttling effect has great potential for high performance lithium-sulfur batteries,yet it remains challenging. Here we propose a novel templated spherical coassembly strategy to fabricate the MoS2/C hollow spheres as an efficient sulfur host material. The unique hollow structure provides enough interior space for accommodating a substantial amount of sulfur, and effectively suppresses the diffusion of dissolved polysulfides by both physical confinement and chemical adsorption. Moreover, the ionic transport as well as the ability to mitigate volume variation upon cycling is also improved, thereby maximizing the utilization of sulfur. Owing to these merits, when evaluated as a sulfur host for lithiumsulfur batteries, the MoS2/C hollow spheres exhibit appealing electrochemical performance with an impressive specific capacity of 1082 mA hg-1at 0.1 C, excellent rate capability and superior cycling stability with a low fading rate of 0.04% per cycle.

Fiber electronics with flexible and weavable features can be easily integrated into textiles for wearable applications. However, due to small sizes and curved surfaces of fiber materials, it remains challenging to load robust active layers, thus hindering production of high-sensitivity fiber strain sensors. Herein, functional sensing materials are firmly anchored on the fiber surface in-situ through a hydrolytic condensation *** anchoring sensing layer with robust interfacial adhesion is ultra-mechanically sensitive, which significantly improves the sensitivity of strain sensors due to the easy generation of microcracks during stretching. The resulting stretchable fiber sensors simultaneously possess an ultra-low strain detection limit of 0.05%, a high stretchability of 100%, and a high gauge factor of 433.6, giving 254-folds enhancement in sensitivity. Additionally, these fiber sensors are soft and lightweight, enabling them to be attached onto skin or woven into clothes for recording physiological signals, e.g. pulse wave velocity has been effectively obtained by them. As a demonstration, a fiber sensor-based wearable smart healthcare system is designed to monitor and transmit health status for timely intervention. This work presents an effective strategy for developing high-performance fiber strain sensors as well as other stretchable electronic devices.

Polyvinyl chloride (PVC), is one of the main synthetic materials used widely in many applications of our life aspects today. Though, the practical usage of it was always affected by some destructive factors like UV-light and heat. The optical and surface characteristics of pure and modified PVC thin films were compared throughout a temperature range of 25–55 °C. It was found that the intensity of the amine group in modified PVC varied with temperature. Surface morphology properties studied by AFM results;the ionic liquid was proven to comparably increases the stability of PVC surface while the roughness was less than pure PVC with increasing temperature. Optical microscope pictures, manifest PVC as drops at 55 °C, while, in modified PVC at the same temperature, the PVC surface was noticeably more stable. Finally, the energy gap of PVC pure and modified PVC thin films are studied. At 55 °C, the modified PVC's energy gap value increased from 3.64 eV at ambient temperature to 4.28 eV. This makes it more isolated when compared to pure PVC, which has an energy gap of 3.04 eV at ambient temperature and 3.1 eV at 55 °C and is a semiconductor. © 2023, The Author(s).

Harnessing the distinct features of nanoparticles and nanomaterials for biomedical use has seen remarkable progress in recent years. Tellurium nanoparticles (TeNPs) have attracted attention due to their exceptional properties and potential uses in photoconductivity, nonlinear optics, piezoelectricity, and thermal conductivity applications. This study synthesized TeNPs through a novel heat reduction method using ascorbic acid as a reducing agent, followed by various characterization studies. Functional studies, such as the antibacterial activity, antioxidant activity and cytotoxicity assays, AO/EB staining, and live cell imaging were performed using TeNPs. The various concentrations of TeNPs (5 − 20 µg/ml) result in inhibition zones against *** in the 5-13 mm range and against *** in the 6-12 mm range. The produced TeNPs minimum inhibitory concentration (MIC) demonstrated that these nanoparticles had antibacterial properties against the tested gram-positive and gram-negative bacterial strains. Moreover, TeNPs exhibit strong antioxidant properties and demonstrate high toxicity in C2C12 myoblastoma cells. Notably, at a concentration of 5 µg/ml, TeNPs exhibit potential toxicity. Live cell imaging and cell proliferation assay with high and lower concentrations of TeNPs retards cell growth and proliferation of C2C12 myoblastoma cells compared to control. Based on the results, due to the increased toxicity nature of TeNPs, lower concentrations below 5 µg might be used in scaffolds to enhance cell proliferation for regenerative medicine and tissue engineering applications. © The Author(’s).

Metal-free heteroatom doped nanocarbons are promising alternatives to the metal-based materials in catalytic ozonation for destruction of aqueous organic contaminants. In this study, N, S co-doped hollow carbon microspheres (NSCs) were synthesized from the polymerization products during persulfate wet air oxidation of benzothiazole. The contents of doped N and S as well as the structural stability were maneuvered by adjusting the subsequent N_(2)-annealing temperature. Compared with the prevailing single-walled carbon nanotubes, the N_(2)-annealed NSCs demonstrated a higher catalytic ozonation activity for benzimidazole degradation. According to the quantitative structure-activity relationship (QSAR) analysis, the synergistic effect between the graphitic N and the thiophene-S which redistributed the charge distribution of the carbon basal plane contributed to the activity enhancement of the N_(2)-annealed NSCs. Additionally, the hollow structure within the microspheres served as the microreactor to boost the mass transfer and reaction kinetics via the nanoconfinement effects. Quenching and electron paramagnetic resonance (EPR) tests revealed that benzimidazole degradation was dominated by the produced singlet oxygen (^(1)O_(2)) species, while hydroxyl radicals (^(·)OH) were also generated and participated. This study puts forward a novel strategy for synthesis of heteroatom-doped nanocarbons and sheds a light on the relationship between the active sites on the doped nanocarbons and the catalytic performance.

With increasing risks of climate change, the water resources have also been declining, and to address this many water treatment and water separation technologies has emerged. Water-based microfiltration membranes (MF) offer numerous benefits over other types of membranes, such as energy efficiency, high flux, and ease of operation. The ultrafiltration membrane (UM) technology has the potential to contribute to this water separation process at the greater level, with its features such as small land occupation, lower energy consumption, easy to handle and customize operation allow this technology to widely used. The most promising technique for purifying water is nanofiltration (NF) membranes, which provide several benefits, such as minimal maintenance costs, high penetration flux, low operating pressure, and high retention of multivalent ions. Among different process the polymeric RO membranes are the dominant stream due to their low cost, ease to mold according requirements and ability to modify their structure by different methods (surface modification and filler incorporation). This review article summarizes the issue and challenges of water purification membranes. © The Author(s), under exclusive licence to Iranian Society of Environmentalists (IRSEN) and Science and research Branch, Islamic Azad University 2025.
