Summary: This study investigates the influence of different temperatures (25°C, 45°C, and 55°C) on q235 steel specimens, analyzing the impact on the morphology and corrosion resistance of modified boron nitride nanosheets incorporated into the phosphate coating. The characterization of the coating's morphology and surface modification was done using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The results showed that the S-45 steel sample had a higher number of nucleation sites, reduced grain size, and a denser, more robust, and more corrosion-resistant phosphate coating compared to the S-25 and S-55 samples. The potentiodynamic polarization results demonstrated that the S-45 steel sample exhibited the best corrosion resistance performance, with the lowest electric current density, an order of magnitude lower than the S-25 and S-55 samples. The coating weight results showed that the S-45 steel specimen achieved the densest and most uniform coating (32.14 g/m²).

Summary: In this work, PDA@BN-TiO2 nanohybrid particles were chemically incorporated into a zinc-phosphating solution to form a robust, low-temperature phosphate-silane coating on Q235 steel specimens. The incorporation of PDA@BN-TiO2 nanohybrids resulted in a denser, more corrosion-resistant phosphate coating with smaller grain size and more nucleation sites compared to pure coating. The PDA@BN-TiO2 nanohybrids also improved the homogeneity and anti-corrosive capabilities of the phosphate-silane films.

Summary: The corrosion inhibitive performance of calcium modified zinc phosphate coating on A36 mild steel was studied. The results showed that the calcium modified phosphating process at 80 degrees C with a calcium concentration of 2.5 g/L provided a better and more uniform coating on the steel surface. The adsorption of both calcium and zinc particles on A36 mild steel was found to be a spontaneous and physical process, as indicated by the Freundlich adsorption isotherm and the values of Kads and Delta Gads.

Summary: The direct growth of hexagonal boron nitride (h-BN) nanofilms on stainless steel (ss304) using the magnetron sputtering method serves as an effective barrier coating for protection in corrosive environments. These nanofilms, with a highly densified morphology and hydrophobic surface, exhibit excellent oxidation resistance at high temperatures and enhanced anticorrosion performance compared to bare ss304. The results suggest that h-BN nanofilms hold great promise for long-term corrosion protection and antioxidation of steel surfaces in practical applications.

Summary: This study presents a new method for directly fabricating a superhydrophobic surface coating on mild steel. Dielectric barrier discharge (DBD) plasma was used to convert a liquid small-molecule precursor to a solid film through plasma-assisted on-surface polymerization. The properties of the coating were analyzed using various techniques, including microscopy, spectroscopy, and contact angle measurement. The results showed that the wettability of the films could be controlled by adjusting the plasma parameters and incorporating graphene nanoplatelets in the precursor. High-dose plasma exposures of the nanoplatelet-containing precursor resulted in the formation of superhydrophobic films with water contact angles above 150 degrees. However, the superhydrophobic coating provided limited corrosion protection according to potentiodynamic polarisation tests.

Summary: A series of Ni catalysts were synthesized by controlled thermal treatment of Ni-based metal-organic frameworks (MOFs) to achieve selective hydrogenation of furfural to tetrahydrofurfuryl alcohol under facile conditions. The catalytic performance of Ni/C catalyst obtained at 400 degrees C showed high conversion of furfural (>99%) and selectivity to tetrahydrofurfuryl alcohol (96.1%), under facile conditions (80 degrees C, 3 MPa H-2, 4.0 h). The decomposition of MOF at low temperatures resulted in highly dispersed Ni-0 particles and interfacial charge transfer, enabling the facile hydrogenation process.

Summary: Two-dimensional metal-organic frameworks have been widely studied due to their unique properties. However, the process of crystallization in these frameworks is not well understood. Using the microdroplet flow reaction technique, researchers were able to capture different states of Cu-BDC during crystal growth and uncover a nonclassical crystallization mechanism. The intermediate state product of Cu-BDC nanosheets showed enhanced catalytic performance due to its accessible active sites. This finding can guide the rational design of various 2D MOFs with special structures.
