Summary: By using bamboo as the raw material, a thin-walled hollow ellipsoidal carbon-based adsorbent (CPCs900) has been fabricated, which exhibits excellent performance in removing lead ion (Pb2+) from water with high adsorption capacity and efficiency. The outstanding adsorption performance of CPCs900 is attributed to the abundant O-containing groups and carbon defects as well as the large specific surface area. Converting bamboo into highly efficient adsorbents for removing toxic metal ions from water is of great significance for meeting industrial demands.

Summary: Experimental realization of thin films with significant room-temperature magnetoelectric coupling coefficient α(ME) without an external DC magnetic field has been challenging. Here, large α(ME) of 750 +/- 30 mV Oe(-1) cm(-1) is achieved in multiferroic polymer nanocomposites (MPCs) thin films. The MPCs consist of PMMA-grafted cobalt-ferrite nanoparticles uniformly dispersed in piezoelectric polymer P(VDF-TrFE). Nanoparticle agglomeration is reduced by surface functionalization with PMMA, enabling the uniform dispersion of nanoparticles in submicrometer thin films. This research can promote the development of flexible and printable multiferroic electronic devices for sensing and memory applications.

Summary: Polymer nanocomposites (PNCs) consisting of Au nanoparticles (AuNPs) incorporated in semiconducting polymers (SPs) were studied. The dispersion and locations of the AuNPs, as well as the crystallinity of the SPs, were found to affect the device performances. The results showed that the AuNPs self-organized near the film interfaces and diffused through the amorphous regions of P3HT during thermal annealing, leading to improved crystallinity and connectivity of P3HT.

Summary: The study investigates the selective deoxygenation of carboxylic acid on promoted MoO3, revealing the potential for synthesizing valuable renewable products. The results suggest that the deoxygenation of pentanoic acid on an oxygen vacancy of MoO3 can be explained by a Langmuir-Hinshelwood mechanism. The incorporation of Pt shifts the reaction order with respect to hydrogen and alters the rate-determining step.

Summary: In this study, the role of water in the selective hydrogenation of cinnamaldehyde was investigated. It was found that boron species exsolve from the bulk phase and become enriched on the surface, forming acidic species that enhance the activity and selectivity of carbonyl bond hydrogenation. Metal-support interactions result in smaller particles and a drop in selectivity towards unsaturated alcohol. The presence of boron species and strong metal-support interactions protect the catalysts from water attack, resulting in enhanced stability.

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.
