Article Synopsis
- In maritime settings, PEMFCs face contamination risks from salt spray, which can irreversibly degrade their performance.
- To tackle challenges of testing sodium chloride's impact on PEMFCs, the article introduces a standard salt spray chamber to recreate marine conditions and uses a liquid nitrogen fracture method for efficient sample preparation.
- The study results affirm the effectiveness of the developed salt spray method for analyzing contamination in the membrane electrode assembly (MEA), enabling detailed physicochemical and microscopic investigations of NaCl effects.
Antibacterial Nanocellulose-TiO/Polyester Fabric for the Recyclable Photocatalytic Degradation of Dyes.

Zhoushan Institute of Calibration and Testing for Quality and Technology Supervision, Zhoushan 316000, China.
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.

Article Synopsis
- The research focused on creating S-scheme heterojunctions, specifically BiSnO/β-BiO photocatalysts, to improve environmental cleanup, particularly in degrading tetracycline hydrochloride.
- The optimized photocatalysts showed a degradation efficiency of 95.5%, significantly outperforming β-BiO alone by 2.68 times due to better separation of photoelectron-hole pairs and enhanced reactive site exposure.
- Additionally, the BiSnO/β-BiO heterojunction demonstrated impressive stability, maintaining over 89.7% efficiency after five cycles of degradation processes.
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.

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.

School of Materials Science and Chemical Engineering, Ningbo University, Ningbo 315211, China.
Article Synopsis
- PBAT is a fully biodegradable polymer that, when mixed with thermoplastic starch (TPS), creates films like disposable bags, but this blend reduces tensile strength.
- Microcrystalline cellulose (MCC) was added to the PBAT/TPS blend to enhance its mechanical properties; the study found that 4% MCC significantly improved tensile strength and elongation.
- The addition of MCC also enhanced the thermal stability of the film and maintained good compatibility with PBAT and TPS when MCC content was below 6%.
