Summary: The photoexcited charge separation efficiency is usually considered as the key factor for enhancing the photocatalytic activity of photocatalysts. However, the role of the interfacial affinity between photocatalysts and substrates is rarely studied systematically. In this study, nitrogen vacancy-modified polymeric carbon nitride porous nanotubes (PCNpts) were synthesized and showed significant improvements in surface area, wettability, photoabsorption, charge separation capability, and photocatalytic activity in water splitting. Interestingly, the photoactivity of PCNpts showed substrate-dependent variation in contaminant degradation compared with bulk PCN. It was found that the interfacial affinity between PCNpts/PCN and contaminants/H2O, rather than the photoabsorption and charge separation capability, dominated their photoactivity.

Summary: Bicomponent regenerated cellulose fibers (bRCF) were created in a core-shell configuration from waste textiles, achieving coloration by utilizing colored textile waste. The optimized bRCF had 49.6% dyed material yet achieved the same color strength as single component RCF, showcasing potential benefits of reducing colored material while maintaining color intensity. Mechanical properties of bRCF were similar to single component RCF, with a unique core-shell structure visible in optical micrographs.

Summary: The random mobility of charge carriers in g-C3N4 can lead to low photocatalytic efficiency. Controllable migration of charge carriers is proposed as a strategy to suppress charge recombination and facilitate charge separation. In this study, ethylenediamine modified g-C3N4 is found to exhibit improved photocatalytic activity, with enhanced charge separation being identified as a key contributing factor. TEM observation and DFT calculations reveal the accumulation of electrons on certain areas of the modified g-C3N4 surface. The introduction of -NH2 groups through modification significantly alters the electronic structure of g-C3N4, leading to the generation of midgap states that impact charge separation. This research offers a simple method to manage charge carrier migration and enable electron directional transfer, thereby suppressing recombination and enhancing photocatalytic activity.

Summary: The incorporation of transition metals in polymeric carbon nitride is an effective strategy to enhance its photocatalytic CO2 reduction activity. By controlling the content of metal-organic frameworks during pyrolysis, the photocatalytic activity of metal-modified carbon nitride is optimized. The optimized materials show significantly enhanced CO evolution rates, which can be attributed to various factors such as increased specific surface area and visible light absorption.

Summary: The study evaluated the durability of ZnO and TiO2 nanoparticles-modified cotton terry textiles in terms of photocatalytic and antimicrobial activities. Results showed that the efficiency of self-cleaning properties and antimicrobial activity depended on UVA/B radiation intensity, with a significant increase in photocatalysis effectiveness at higher radiation intensities. A biocidal effect against all tested microorganisms was observed at a UVA/B radiation intensity of 1400 mu W/cm(2). Additionally, the antimicrobial activity of washed materials could be increased by irradiation with a light bulb.

Summary: The production of lightweight vehicles is driven by the global challenges of fuel economy enhancement and greenhouse gas emissions reduction. Lightweight materials, such as fiber-reinforced plastics (FRP) composites, are being developed to replace conventional materials like steel and cast iron to achieve fuel efficiency and CO2 emission reduction. However, the damage of FRP composites under impact loading is a critical factor that affects their structural application. This paper focuses on the use of high-strength glass fibers as the reinforcing member to develop a car bumper beam, discussing its mechanical performance and manufacturing techniques. Based on literature studies, glass fiber-reinforced composite (GRP) shows more promise in the automotive industry compared to conventional car bumper beams.

Summary: Emission of greenhouse gases and increasing global warming posed threats to the environment and mankind survival. Construction industry, one of the leading polluters, heavily relies on traditional materials for new facilities construction. The main constituent of concrete, cement, and steel reinforcement used in it require significant energy consumption, resulting in intensive carbon dioxide emissions. To address this issue, the utilization of industrial by-products and textile waste as replacements for cement and reinforcement materials provide promising solutions in reducing waste disposal and energy demand for concrete production. This paper provides an overview of the efforts made in reducing dependence on traditional materials in cementitious composites.

Summary: In this study, a novel harp structure was developed to collect water directly from fog, which showed a higher fog harvesting rate compared to the conventional Raschel mesh. The use of polyethylene monofilament as a collector's element in the harp contributed to this improvement. Furthermore, the application of a silane coating on the harp surface enhanced the hydrophobicity and fog collection efficiency. The characterization of samples was done using HR-SEM, EDX, and AFM techniques.
