Summary: Graphene and multilayer graphene (MLG) have versatile properties and wide applications, but their production is challenging. This paper explores metal-induced crystallization to synthesize MLG directly on metal films and insulating substrates at much lower temperatures. Raman spectroscopy confirms the MLG properties of the synthesized carbon structure. The presented tip-based approach offers a simpler fabrication solution for MLG by eliminating photolithographic and transfer steps.

Summary: Graphene oxide (GO) has various applications in energy devices, biomedicine, environmental protection, and composite materials. A stepwise electrochemical method for fast GO preparation is reported, which involves spontaneous persulfate intercalation and anodic electrolytic oxidation. This method avoids uneven intercalation and insufficient oxidation, significantly shortening the overall duration, and resulting in GO with higher oxygen content and enhanced adsorption capacity compared to traditional methods.

Summary: The current study investigated the interaction between graphene oxide (GO) additive and magnesium hydride (MgH2), leading to the transformation to reduced graphene oxide (rGO). The results showed that the in situ transformation of GO to rGO reduced the dehydrogenation temperature of MgH2, increased the hydrogen ab/desorption reaction kinetics, and decreased the dehydrogenation activation energy. The study also demonstrated the potential of using magnesium hydride to trigger the GO to rGO transformation for the preparation of rGO and rGO composite materials, which are important for energy storage applications.

Summary: A heterogeneous catalytic system for the acceptorless dehydrogenative condensation between N,N'-disubstituted ureas and 1,2-diols to produce imidazolones was developed. The designed palladium nanoaggregates on an alumina matrix showed good activity and selectivity, with wide applicability and moderate to good yields. Mechanistic studies and characterization were performed, revealing the key factors for the catalyst's activity. Furthermore, a Pd-Zn cooperation effect was described, and bimetallic materials were also designed and characterized properly.

Summary: Graphene nanomaterials have been commercialized and disseminated into surface waters, but their photodegradation in natural aquatic environments is minimal and slow. This study evaluated the photodegradation of graphene oxide and partially reduced graphene oxide in Columbia River Water, finding that both direct and indirect photolysis occur simultaneously. However, the concentrations of photosensitizers in surface water are not sufficient to initiate degradation of graphene oxide. Overall, graphene nanomaterials show minimal phototransformation in natural surface water.
