Summary: The study revealed the significant impact of meta-position iminopyridine substituents on the antitumor activity of carbosilane metallodendrimers. New Cu(II) carbosilane metallodendrimers with methyl or methoxy substituents demonstrated low micromolar IC50 values in tumor cell lines, and in vitro assays indicated improved cytotoxicity and selectivity. The most promising candidates exhibited a substantial increase in antitumor activity in U937 tumor cells, possibly through different ROS-production pathways.

Summary: Designing and developing clay-based adsorbents with a strong preference for removing copper and zinc metal ions, reduced cost, eco-friendliness, and good recyclability is a good strategy for water remediation. Herein, halloysite nanotubes (HNT) were activated by (3-chloropropyl) trimethoxy silane (CPTM) as a linker for polyethyleneimine to give HN-PEI. The hybrid organic/inorganic sorbent HN-PEI showed improved textural properties and exhibited selective adsorption of Cu(II) and Zn(II) metal ions from water. It also demonstrated high durability over multiple cycles and excellent selectivity and efficiency for Cu(II), Pb(II), and Zn(II) ions.

Summary: N, N-dimethylformamide (DMF) plays a crucial role in chemical industry and materials science. In this study, silica supported polyamidoamine (PAMAM) dendrimers were synthesized and used to adsorb Cd(II) and Cu(II) metal ions from DMF solution. The adsorption amount followed the order of SG/G2 > SG/G3 > SG/G1. The adsorption process reached equilibrium within 240 min and followed a pseudo-second-order kinetic model. High temperature and metal ion concentration were found to promote the adsorption. The adsorption was spontaneous, endothermic, and chemisorption in nature, and could be described by the Langmuir model. Theoretical calculations suggested that the adsorption occurred through the formation of tetra-coordinated complexes involving tertiary amino N and carbonyl O atoms.

Summary: The bottleneck in hybrid lithium-sodium-ion batteries lies in the lack of anode materials with desired rate capability. In this study, the lithium storage performance of sodium titanate nanowires as negative electrodes in hybrid Li,Na-ion batteries was thoroughly examined. The nanowires exhibited a hybrid capacitive-diffusive mechanism for lithium storage, achieving a high specific capacity. Sodium titanates accommodated Li+ by forming mixed lithium-sodium-phase Na2-xLixTi6O13, while sodium storage was mainly accomplished by capacitive reactions, preserving the phase composition during cycling. Isolated nanowires outperformed bundled nanowires in terms of rate capability.

Summary: After a delay of more than 30 years, sodium analogs are now entering the market as an alternative to lithium-ion batteries. These sodium-ion batteries address concerns about sustainability, production costs, safety, and toxicity. The electrode materials of these batteries can contain sodium, iron, or manganese, eliminating the need for cobalt cathode compounds and copper anode current collectors. Manganese, with its multiple oxidation states and abundance, is favored as a component in these batteries. However, further research is needed to explore the role of manganese in different structural families.

Summary: The redox properties of quinones, which can be precisely tuned by using different substituent groups, make them superior as organic battery components compared to conventional inorganic ones. Machine learning and statistics have proven to be powerful tools for efficient design of new materials. In this study, a machine learning approach was used to predict the redox activity of quinones, with the aim of designing organic battery components. Various statistical methods were applied to select descriptors that characterized the relationship between structure and redox potential, and different machine learning methods were deployed to screen potential organic battery electrode materials.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
