Summary: In this study, a polyaniline/NH2-MIL-125 (PANI/MIL) heterojunction decorated hydrolyzed polyacrylonitrile (HPAN) membrane with photocatalytic self-cleaning property was fabricated for oil-water separation and bacterial inactivation. The composite membrane exhibited excellent separation efficiency and high flux in emulsions separation, as well as 100% photocatalytic inactivation efficiency against bacteria under visible light. The coupling of conductive polymer PANI enhanced the underwater superoleophobicity and improved the photocatalytic activity, making the PANI/MIL@HPAN multifunctional membrane achieve superior performance in oil/water separation and antibacterial activity.

Summary: In this study, we investigate the adsorption behavior of MIL-125-NH2 in CO2/H2S mixtures and calculate the defect formation energy of the MOF after H2S exposure. The results show that the MOF is stable under dry H2S exposure and exhibits higher selectivity for H2S than predicted. The experimental findings suggest that MIL-125-NH2 has great potential for H2S removal in biogas.

Summary: The photocatalytic H2 evolution rates of NH2-MIL125(Ti) MOF sheets with different {001}/{111} facets exposure ratios were found to increase linearly with the proportion of {001} facets. The optimal activity of approximately 2640 μmol h-1 g-1 is superior to other NH2-MIL-125(Ti)-based photocatalysts reported. This facets effect is attributed to the distinct charge separation abilities of different Ti atoms in the {001} and {111} facets.

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.

The nano biofungicide was prepared through one pot hot melt ultrasonication technique with easy water dispersibility and long term stability. The physico-chemical analysis revealed that, nano bio-fungicides were amorphous sphere-shaped nanoparticles with low melting point. The encapsulation efficiency of major components of essential oil was determined, and it was found that they followed Higuchi model of release kinetics. The essential oil loaded nanostructured lipid carrier showed significantly higher mycelial growth inhibition compared to pure essential oil, indicating enhanced bio-efficacy.
