Experimental Investigation for Proton Exchange Membrane Fuel Cells in Marine Salt Spray Environment.

In the maritime setting, Proton Exchange Membrane Fuel Cells (PEMFCs) are subjected to salt spray, posing a risk of contaminating internal components and leading to irreversible degradation in the performance of the PEMFCs. Thus, it is crucial to assess the impact of sodium chloride contamination on PEMFC operation. To address challenges related to prolonged cycle times, high costs, and intricate sample preparation in sodium chloride contamination experiments for PEMFCs, this Article replicates the marine atmospheric conditions using a standard salt spray experimental chamber.

Antibacterial Nanocellulose-TiO/Polyester Fabric for the Recyclable Photocatalytic Degradation of Dyes.

In this paper, we report an antibacterial, recyclable nanocellulose-titanium dioxide/polyester nonwoven fabric (NC-TiO/PET) composite for the highly efficient photocatalytic degradation of dyes. The NC-TiO was loaded onto the surface of flexible PET nonwoven fabric through a simple swelling and dipping method. The NC-TiO in the particle size range of ~10 nm were uniformly attached to the surface of the PET fibers.

Self-Assembly of BiSnO/β-BiO S-Scheme Heterostructures for Efficient Visible-Light-Driven Photocatalytic Degradation of Tetracycline.

Fabrication of S-scheme heterojunctions with enhanced redox capability offers an effective approach to address environmental remediation. In this study, high-performance BiSnO/β-BiO S-scheme heterojunction photocatalysts were fabricated via the in situ growth of BiSnO on β-BiO microspheres. The optimized BiSnO/β-BiO (BSO/BO-0.

Preparation of asymmetric Janus hollow silica microparticle and its application on oily wastewaters.

Janus nanoparticles have aroused the interest of scholars because of their highly efficient emulsification of spilled oils in wastewater. In this work, interfacially active Janus hollow glass microparticles (J-HGMPs) of asymmetric wettability were designed and synthesized in order to achieve more efficient separation of emulsified oil droplets from oily wastewater. Surface characteristic techniques such as FTIR, SEM, zeta potential and contact angle measurements had been employed to assess the amphiphilic surface properties of J-HGMPs.

Study on the physicochemical indexes, nutritional quality, and flavor compounds of from three representative origins for geographical traceability.

Trichiurus lepturus (hairtail) is an important economic component of China's marine fishing industry. However, due to the difficulty in identifying the appearance of hairtail from different geographical distributions, hairtails with geographical indication trademarks were imitated by general varieties. In this study, the texture characteristics, color, basic nutrients, amino acids, mineral, fatty acids, and volatile flavor substances were used as indicators for multivariate statistical analysis to determine whether three origins of hairtails from the habitats of Zhoushan (East China Sea, T.

Effect of Microcrystalline Cellulose on the Properties of PBAT/Thermoplastic Starch Biodegradable Film with Chain Extender.

Poly (butylene adipate-co-terephthalate) (PBAT) is a fully biodegradable polymer with toughness and ductility. It is usually compounded with thermoplastic starch (TPS) to balance the cost for manufacturing biodegradable films such as disposable plastic bags. However, blending with TPS reduces valuable tensile strength, which limits the bearing capacity of PBAT film.

synthesis of TiO/NC on cotton fibers with antibacterial properties and recyclable photocatalytic degradation of dyes.

A cotton fabric/titanium dioxide-nanocellulose (TiO-Cot.) flexible and recyclable composite material with highly photocatalytic degradation of dyes and antibacterial properties was synthesized. During the preparation process, nano-TiO particles were synthesized through an strategy and grown on cotton fiber, and were wrapped with cellulose nanocrystals (NC).

Dual-valve parallel prediction control for an electro-hydraulic servo system.

To improve the dynamic response performance of a high-flow electro-hydraulic servo system, scholars have conducted considerable research on the synchronous and time-sharing controls of multiple valves. However, most scholars have used offline optimization to improve control performance. Thus, control performance cannot be dynamically adjusted or optimized.
