Summary: The use of macro-porous alumina as a support for Cu-based desulfurization sorbents improves sulfur capacity and facilitates CO production during the desulfurization reaction. Density functional theory calculations suggest that desulfurization kinetics are strongly influenced by the local surface environment, with CO generation having lower adsorption energy than CO2 formation.

Summary: This study discusses the concern over heavy metals and pollutants in petroleum wastewater and presents the synthesis and characterization of ZnO@CuO nanocomposite. The results show that the ZnO@CuO nanocomposite achieved 100% removal efficiency under optimal conditions and the removal process followed both first and second-order kinetic models. The adsorption process also followed the Langmuir isotherm model. The study highlights the potential of green-synthesized ZnO@CuO NPs as effective adsorbents for heavy metals and pollutants in petrochemical wastewater.

Summary: The study analyzed the quality of borehole water from Ikot Ada Udo and found variations in heavy metals, TPH, and physico-chemical parameters levels. Some samples exceeded the drinking water standards for certain contaminants, possibly due to contamination introduced by produced water.

Summary: China has become the world leader in crude oil processing capacity in 2021. However, the petroleum refining industry generates significant VOC emissions, and the understanding of VOC emissions in this industry is still limited. This study systematically evaluated the historical emissions and reduction of VOCs in the petroleum refining industry in Guangdong, China's major province for crude oil processing, from 2001 to 2020. The results showed that VOC emissions followed an increasing-then-decreasing trend, with storage tanks and wastewater treatment as the largest sources. Efforts to reduce VOC emissions have shown positive results.

Summary: The contamination of soils with petroleum and its derivatives is a persistent and growing environmental problem, however the interference of heavy metals co-contaminating these soils is often overlooked. Acinetobacter baumannii strain JYZ-03 was identified as capable of degrading petroleum hydrocarbons and isolated from soil contaminated by both heavy metals and petroleum hydrocarbons. Strain JYZ-03 effectively bioremediates petroleum hydrocarbon-contaminated soil in the presence of heavy metal stress, making it valuable in the bioremediation of petroleum- and heavy-metal-contaminated sites.

Summary: Many industrial processes produce waste with toxic and precious metal pollutants. Current remediation strategies lack the selectivity needed to effectively eliminate heavy metals. Sulfur is well known for its ability to selectively bind heavy metals. This study combines sulfur with charged monomers to form water-soluble polysulfides, which have demonstrated selective binding to metals and enhanced solubility in organic solvents.

Summary: Petroleum hydrocarbons and heavy metals are widespread contaminants in marine ecosystems, and microbial-based bioremediation shows promise as an effective and sustainable solution. In this study, we enriched the microbiome of heavily polluted sediments and isolated two novel bacterial strains that exhibited high degradation of PAHs and removal of HMs, with the best results observed for naphthalene, pyrene, and lead. The genetic repertoire of these strains may be further utilized for bioremediation of marine environments contaminated with PAHs and HMs.

Summary: This work proposes a new architecture of photoelectrodes consisting of supported multishell nanotubes fabricated by a soft-template approach. The obtained NT electrodes have a large electrochemically active surface and outperform the efficiency of equivalent planar-layered electrodes by more than one order of magnitude. The characteristics of the WO3/BiVO4 Schottky barrier heterojunction control the NT electrode efficiency, which depends on the BiVO4 outer layer thickness and the incorporation of the CoPi electrocatalyst, as demonstrated by thorough electrochemical analysis.

Summary: The formation of monoclinic VO2 crystal domains at low temperatures in nanocolumnar vanadium/oxygen thin films deposited via magnetron sputtering is analyzed. The synthesis involved depositing amorphous nanocolumnar VO1.9 thin films at room temperature and annealing them at temperatures between 250 - 330 ? in an oxygen atmosphere. The nanocolumnar structures exhibited a thermochromic transition at 47 ? (for annealing at 270 ?) and 58 ? (for annealing at 280 and 290 ?), resulting in a significant drop in optical transmittance in the infrared region.

Summary: This study investigates the synthesis of ammonia using plasma-catalysis and examines the role of various catalyst materials. The results show that while ruthenium particles have some catalytic activity under certain conditions, they do not significantly improve the yield and energy efficiency of ammonia synthesis. The ferroelectric material and the alumina coating play important roles in regulating discharge and cooling the plasma, respectively.

Summary: In this study, a novel methodology of plasma-assisted thin film structuration was proposed by combining piezoelectric AWs and plasmas during the growth of a thin film. SiO2 and SiOx (x<2) thin films were deposited by magnetron sputtering at oblique angles (MS-OAD) on an electro-acoustically excited LiNbO3 piezoelectric substrate under resonant conditions. The resulting films exhibited 2D patterned microstructure with submillimeter size intermingled zones, which replicated the distribution of polarization potential on the AW activated substrate immersed in the plasma. The main mechanism responsible for the appearance of domains with different morphology and chemical composition was found to be the focused impingement of Ar+ plasma ions on certain regions of the substrate. The discussed the general character of this patterning process, the underlying physics, and its possibilities to tailor the composition and microstructure of dielectric thin film materials.

Summary: In this study, we have developed a method using lower laser irradiation conditions to generate aluminum surfaces with dual-scale roughness, resulting in double or even triple the Sp parameter values compared to reference samples. This was achieved by coating aluminum substrates with a highly transparent aluminum oxynitride capping layer. The resulting surfaces, consisting of partially oxidized aluminum with negligible amounts of nitrogen species, exhibited high hydrophobicity and showed long icing delay times for anti-icing applications. A correlation was found between the wetting and anti-icing behaviors, the use of a capping layer, and the laser irradiation conditions.

Summary: Carbon nanodots (CNDs) are used as fluorescent nanosensitizers to enhance the photocatalytic response of semiconductors beyond the ultraviolet range. The addition of nitrogen heteroatoms to the carbogenic network of CNDs improves their photostability and optical properties. Laser pyrolysis is a versatile technique for synthesizing N-doped CNDs by using a liquid solvent containing nitrogen as the carbon precursor. These N-doped CNDs exhibit enhanced photoactivity when combined with P25 nanoparticles for the conversion of methyl orange under white LED illumination, generating various reactive oxygen species.

Summary: Plasma reactions of CO2 + CH4 mixtures for dry reforming of methane have been studied in a ferroelectric-moderated packed-bed reactor. The analysis results suggest that there are few direct interactions between intermediate plasma species from CH4 and CO2. Experiments using 13CO2 as reactant confirmed this preliminary finding. The results highlight the need for catalysts to control the selectivity of the process.

Summary: Cold plasma treatments are effective in promoting seed germination under nonstress conditions and also have positive effects on germination under environmental stress conditions. This study focuses on the influence of cold plasma treatments on the germination rate and initial stages of plant growth in common stress environments for barley seeds. The results show that plasma-treated seeds have higher germination rates and induce favorable changes in plant and radicle dimensions.
