Summary: Graphene oxide (GO) composite membranes have been widely used in membrane modification due to their excellent properties, such as huge specific surface area, good electrical conductivity, good hydrophilicity, and various functional groups. The addition of GO in membranes has been proven to improve water permeability, molecular selectivity, membrane fouling mitigation, and contaminants decomposition. Recently, the development of laminated GO in membranes has achieved both high selectivity and high water permeability, overcoming the limitations of conventional polymeric or inorganic membranes. This review systematically summarizes the applications of GO composite membranes in three highlighted areas of environmental fields: desalination, gas separation, and wastewater treatment, and discusses the challenges faced with GO composite membranes.

Summary: Adding g-C3N4 sheets into GO membranes to establish stable and sub-nanometer wide channels can significantly improve salt rejection and water permeance. Experimental and theoretical studies have shown that size exclusion is the main mechanism for high rejections, while the ultra-low friction water flow along g-C3N4 sheets enhances permeation. Additionally, the GO/g-C3N4 membrane exhibits promising long-term, antioxidation, and antipressure stability.

Summary: Graphene oxide (GO) modified graphitic carbon nitride (g-C3N4) was used as a support material to prepare laminated nanofiltration membranes. The modified membranes showed a water permeability of 274.7 L center dot m(-2)center dot h(-1)center dot bar(-1), which was 11.5 times higher than that of GO membranes. The membranes also exhibited excellent selectivity and stability. This study provides a new reference for the development of stable and reliable nanofiltration membranes in water treatment.

Summary: An easy and efficient method was used to fabricate MoO2@GO and WO3@GO nanocomposite membranes with controlled structure and interlayer spacing. These membranes showed good separation for salt and heavy metal ions due to intensive stacking interaction and electrostatic attraction. They exhibited high rejection rates (>70%) for small metal ions such as sodium (Na+) and magnesium (Mg2+) ions, as well as >99% rejection rates for nickel (Ni2+) and lead (Pb2+) ions, with good water permeability of 275 +/- 10 L m(-2) h(-1) bar(-1). We believe that these fabricated membranes have a bright future in next generation desalination and water purification membranes.

The Folina-Ciocalteu method was used to assess the concentration of colored reaction products with peptide bonds. Various analyses such as Raman spectroscopy, SEM, and FTIR were employed to study surface morphology, graphene quality, and chemical structure after surface modification.

Summary: This paper presents the concept of modifying the physicochemical properties of steels by simultaneous diffusion saturation with carbon and chromium or aluminum. Two hybrid surface treatment processes, Al + LPC and Cr + LPC, were found to reduce the amount of retained austenite in steel and improve the corrosion resistance of carburized steels, respectively. These methods are particularly important for vacuum processes and carburizing of low-alloy steel with nickel.

Summary: This study examined the relationship between the crystal form and morphology and rheological properties of peptide-based hydrogels. It was found that there is a correlation between the starting solid material and the self-assembly processes in solution, resulting in different properties of the resulting soft matter. The influence of stereochemistry on the gelation and crystallization processes of Tyr-Tyr cyclic dipeptides was analyzed using various techniques, providing a deeper understanding of the peptide hydrogelation processes at a molecular level. Crystal forms of (ll)-cYY were discovered and described in detail, and the molecular-level justification for the observed precipitation behavior of (dl)-cYY was provided.
