Article Abstract
To improve the thermal, mechanical, and barrier properties of ethylene vinyl alcohol copolymer (EVOH)/aramid pulp (AP), graphene oxide (GO) was used as a compatilizer, enhancer, and barrier to fabricate EVOH-based composites. The results showed that graphene oxide serves as an ideal compatilizer to reinforce the interfacial action between the EVOH matrix and aramid pulp. The EVOH/AP/GO composite presented the best combination of thermal stability, tensile strength, oxygen barrier, and heat deformation temperature by adding only 1 wt% graphene oxide, compared to those of pure EVOH. Moreover, both scanning electron microscopy (SEM) and polarized optical microscopy (POM) photographs demonstrated that the aramid pulp dispersed homogeneously into the EVOH resin with the addition of 1 wt% graphene oxide. Our work provides a novel and facile way for producing a prominent EVOH-based composite, which can be potentially used in packaging fields in the future.

Inspired by "the composition of catechol and amine groups in the adhesive proteins" of marine mussel and "brick-and-mortar" structure of nacre, we use polydopamine (PDA) as "mortar", graphene oxides (GO) nanosheets as "brick", and Pd ions as interfacial reinforcer, to fabricate nacre-like Pd enhanced PDA functionalized GO membranes (Pd@PDA/GO) with vacuum filtration-assisted assembly method. Meanwhile, in situ reduced Pd nanoclusters by PDA chains were well constrained within the resultant Pd@PDA/GO artificial nacre composites. Good interfacial adhesion with dense packing of the GO nanosheets was further confirmed with sub-nano level microstructure characterization by positron annihilation lifetime spectroscopy.

The development of anode materials for lithium-ion batteries must meet the demands for high safety, high energy density, and fast-charging performance. TiNbO is notable for its high theoretical specific capacity, low structural strain, and exceptional fast-charging capability, attributed to its Wadsley-Roth crystal structure. However, its inherently poor conductivity has hindered its practical application.

In recent years, light-controlled ion transport systems have attracted widespread attention, however, the use of photoresponsive materials suffers from rapid carrier recombination, thermal field limitations, and narrow spectral response, which significantly restricts their performance enhancement in osmotic energy conversion. This study innovatively couples "blue energy" (osmotic energy) with "green energy" (solar energy), assembling graphene oxide/molybdenum disulfide/sulfonated cellulose nanocrystal (GO/ MoS/CNC) ion-channel membranes. Under solar irradiation, the energy level difference between MoS and GO effectively suppresses the recombination of photogenerated carriers, generating more active electrons and significantly enhancing the carrier density, thereby improving the current flux and ion selectivity.

Aflatoxin B1 (AFB1) is one of the most toxic mycotoxins that pose great health threats to humans. Herein, an aptasensor-based fluorescent signal amplification strategy is developed for the detection of AFB1. Initially, the AFB1 aptamers labelled with carboxyfluorescein (FAM) are adsorbed onto graphene oxide (GO), triggering energy transfer.

This study presents a straightforward and rapid method for preparing graphene aerogel by integrating a sodium alginate (SA)-metal ion crosslinking system, a bubble template, and an osmotic dehydration process. Graphene oxide (GO) nanosheets were dispersed into the solution crosslinked by SA and metal ions, leading to rapid gelation of GO under ambient conditions. To minimize structural damage to the porous network caused by water molecules during the drying process, an osmotic dehydration technique was employed as an auxiliary drying method.
