Summary: In this minireview, we analyze and summarize a less conventional type of SSHC in which molybdenum dioxo species are grafted onto unusual carbon-unsaturated scaffolds, such as activated carbon, reduced graphene oxide, and carbon nanohorns. The choice of earth-abundant, low-toxicity, versatile metal constituents, and various carbon supports illustrates catalyst by design principles and yields insights into new catalytic systems of both academic and technological interest. Here, we summarize experimental and computational investigations of the bonding, electronic structure, reaction scope, and mechanistic pathways of these unusual catalysts.

Summary: This research investigated the CO2 gas barrier and mechanical properties of fluorine rubber nanocomposites filled with graphene oxide (GO)/Ca/Al layered hydroxide (LDH-Ca2Al) modified by GO. The results showed that GO/LDH-Ca2Al nanocomposite fillers exhibited excellent mechanical properties and thermal stability compared to LDH-Ca2Al. The reaction products of LDH-Ca2Al and GO/LDH-Ca2Al with CO2 were analyzed, and GO/LDH-Ca2Al showed better CO2 resistance stability. The CO2 gas barrier mechanism of polymers filled with GO/LDH-Ca2Al was proposed based on the Arrhenius equation.

Summary: Microbial electrosynthesis using a carbon felt electrode modified with reduced graphene-oxide (rgoCF) as a methanogenic biocathode showed improved methane production compared to a control carbon felt electrode (CF). The rgoCF electrode generated almost 30% higher current density and had lower charge transfer and ohmic resistances by 50%. The presence of bacteria and archaea was also increased in the rgoCF electrode. The study estimated that a high-quality biogas (>95% methane concentration) can be produced within a certain CO2 feeding rate range.

Summary: In recent years, there has been a significant increase in the number of studies focusing on the synthesis and characterization of deep eutectic solvents (DESs). DESs, known for their stability, ease of synthesis, and ability to tailor properties, are considered one of the greenest solvent families used in various fields such as organic synthesis, catalysis, electrochemistry, and medicine. However, there is a lack of research on specific groups of DESs, particularly those comprising organic acids (OA-DESs), despite their potential in biomedical applications. This review aims to highlight the importance and applications of OA-DESs as antimicrobial agents and drug delivery enhancers, providing valuable insights for future developments in this field.

Summary: In this study, a high-temperature reaction between ReS2, MoS2, and KCN was investigated, resulting in the formation of a cluster-based K6[Re6-xMoxS8(CN)5] solid solution. The crystal structure is based on chains of [Re6-xMoxS8(CN)6] cluster units. The composition of the product can be varied within the range of x = 2.75-3.63 depending on the sintering temperature of starting sulfides and the reaction temperature with KCN.

Summary: The study investigated the influence of sintering temperature on the mechanical and tribological characteristics of 2D phase reinforced copper-based composites. The composites containing 2 wt.% of (GO + MoS2)(NP) were sintered at different temperatures using microwave sintering process. The results showed that as the sintering temperature increased, the formation tendency of (GO + MoS2)(NP) pockets increased, affecting the mechanical and tribological properties of the composites. The ultimate tensile strength decreased with increasing sintering temperature, while friction and wear rate initially decreased and then increased beyond a certain temperature.

Summary: In this study, two inorganic polymeric cluster compounds, Cs[Mn(salen)](3)[{Mo6Br6Se2}(CN)(6)] (1) and (H3O)(TBA)[Mn(salen)](2)[{Mo6Br6Se2}(CN)(6)] (2), were synthesized and their structures were characterized. The compounds were built-up using [{Mo6Br6Se2}(CN)(6)](4-) building blocks and Mn(salen)(+) complexes. The counter cations (Cs+ or TBA(+)) played a crucial role in controlling the interactions between the building blocks and the Mn(salen)(+) groups. Compound 1 was obtained by diffusion of K2Cs2[{Mo6Br6Se2}(CN)(6)] cluster compound into a solution of Mn(salen)ClO4, while compound 2 was obtained by addition of tetrabutylammonium bromide into the solution of Mn(salen)ClO4. The structures of 1 and 2 were discussed and compared with relevant examples from literature.

Summary: A series of new cluster compounds containing {Re4Mo2S8} and {Re3Mo3S8} cores have been synthesized and studied. The clusters with different Re/Mo ratios were obtained as separate compounds, allowing for characterization of their spectroscopic and electrochemical properties. The geometry of the clusters was determined using X-ray diffraction analysis, XAS, and quantum chemical DFT calculations. The results showed that the new clusters exhibit similar properties to clusters based on {Re4Mo2Se8} and {Re3Mo3Se8} cores, including the number and position of electrochemical transitions, electronic structure, and changes in geometry upon charge variation.

Summary: In this study, a new method was proposed to attach molecularly imprinted polymers (MIPs) on the surface of reduced graphene oxide (rGO) through covalent bonding. The MIP units were covalently bonded on the rGO material via click chemistry under sonication power, excluding harmful solvents and energy-intensive processes. The electrochemical sensor fabricated using this strategy showed enhanced sensitivity, selectivity, stability, and reproducibility for the detection of chloramphenicol (CAP) in water and real honey samples.

Summary: This paper reports the evidence of photoinduced intermolecular electron transfer from the excited state of the [Mo6I8Cl6](2-) electron-rich cluster to polyoxometalates (POMs). The efficiency of electron transfer is shown to be affected by the global charge density of POMs. This work paves the way for the rational design of photocatalytic systems using cluster-based complexes as robust noble-metal-free photosensitizers.
