Summary: A simple method was developed to prepare ordered mesoporous carbons embedded with molybdenum. Three different ordered molybdenum carbide materials with mesoporous structures were prepared to investigate their influence on HER catalytic efficiency. The ordered mesoporous molybdenum carbide catalysts showed excellent HER electro-catalytic performance, with fCMK-3-MoCx exhibiting the best performance. This was attributed to its high specific surface area and highly ordered mesoporous structure, resulting in efficient proton transport and electron transfer.

Summary: The vibrational dynamics in the sub-THz range of mesoporous silica nanoparticles with ordered cylindrical mesopores were studied. The structure of MCM-41 and SBA-15 particles was determined using SEM, XRD, N2 physisorption, and Raman scattering. The stiffness of the silica walls (speed of sound) was determined using Brillouin scattering measurements and finite element calculations, and the relevance of this approach was discussed based on the comparison with numerical and experimental results and previous works reported in the literature.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
