Summary: The electrocatalytic CO2 reduction reaction (CO2RR) to C2+ products is of great importance. The co-operation of Cu1+ and Cu-0 in the catalysts can yield a high faradaic efficiency (FE), but it is difficult to determine the optimal ratio of Cu1+ and Cu-0. In this study, a strategy to prepare Cu catalysts with different oxidation states, stabilized by the pulsed electrolysis method during CO2RR, was proposed. It was found that Cu catalyst with an oxidation state of +0.41 exhibited the highest efficiency, with a FE of C2+ products at 70.3% in an H-type cell. This work provides a precise method to identify the optimal oxidation state of unstable catalysts in the reaction.

Summary: It is important to synthesize stable Cu(I)-based catalysts to maintain catalytic activity during the electroreduction of CO2. In this study, a hexanuclear Cu cluster with strong cuprophilic interactions was utilized as a secondary building unit (SBU) to construct a stable metal-organic framework (MOF) electrocatalyst. The resulting electrocatalyst exhibited high Faradaic efficiency and large current density, making it one of the best performing stable MOF electrocatalysts.

Summary: The development of peptide-metal frameworks as proteomimetic materials has been limited by the restricted choice of side chains and few variable residues compatible with metal ions. In this study, a noncovalent strategy using g-stacking bipyridyl residues was developed to assemble longer peptides into crystalline frameworks. These materials exhibited proteomimetic behaviors and could be optimized for increased affinity towards complex organic molecules.

Summary: In this article, a new generalized matrix response regression model is proposed for the analysis of multiple-subject network data. The model characterizes the connectivity pattern of the network data and the effect of subject covariates through a low-rank intercept matrix and a sparse slope tensor, respectively. An efficient parameter estimation algorithm is developed, and an error bound for the estimator's accuracy is established. The efficacy of the method is demonstrated through simulations and brain connectivity studies.

Summary: This study reports a new Ruddlesden-Popper (R-P) structure oxide, which is widely used as the electrode material in low temperature solid oxide fuel cells (LT-SOFCs) due to its high catalytic activity and excellent oxygen transport performance. However, there are few reports on its application as the electrolyte material in LT-SOFCs. The researchers prepared a P-N heterostructure by using R-P P-type semiconductor Sm1.2Sr0.8Ni0.6Fe0.4O4+5 (SSNF) oxide material as the electrolyte and N-type semiconductor Sm0.075Nd0.075Ce0.85O2-5 (SNDC) oxide material as the cathode. The 5SSNF-5SNDC composite electrolyte exhibited a high ionic conductivity of 0.201 S.cm-1 and a remarkable fuel cell power density of 1056 mW.cm-2 at 550℃. The results indicate that P-N heterojunctions constructed from oxide materials with highly catalytically active R-P structures exhibit excellent electrolyte performance. This work provides a new perspective for developing advanced electrolytes of LT-SOFCs.

Summary: In recent years, changes in the concentrations and compositions of nutrients in the ocean have negatively affected the biomass and quality of macroalgae. A strain of Gracilariopsis lemaneiformis with a curly branch phenotype has been discovered in China, causing negative impacts on the cultivation industry. The abnormality of this strain is correlated with the concentration of nitrogen and phosphorus, and certain biological processes are down-regulated compared to the normal strain.

Summary: This study investigates the compatibility of Na2Ti3O7@C anode material with sodium perchlorate (NaClO4)-based and sodium trifluoromethyl sulfonate (NaCF3SO3)-based electrolytes in sodium ion batteries (SIBs). The results reveal that the NaCF3SO3-based electrolyte forms a thin, compact, and uniform solid electrolyte interphase (SEI) film, which reduces the transmission energy barrier of Na+ and improves the cycling and rate performance of batteries. In contrast, the NaClO4-based electrolyte leads to the formation of a thicker SEI film containing Na(2)CO(3) and NaF, resulting in higher interface impedance and decreased battery cycle performance.

Summary: The acid-base properties of supports have a significant impact on the selectivity and activity of supported catalysts. In this study, a series of Pd-X-UiO-66 (X = -NO2, -NH2, and -CH3) catalysts with different acidity/alkalinity functional groups and encapsulated Pd(II) species were developed and their activities in dimethyl carbonate (DMC) catalysis were investigated. The Pd-NO2-UiO-66 catalyst with acidity functionalization exhibited the best catalytic behavior, with a DMC selectivity of 68% and a CO conversion of 73.4%. The results showed that the -NO2 group not only affected the interaction between X-UiO-66 and Pd(II) active sites, but also played a crucial role in the adsorption and activation of MN and CO, promoting the formation of the COOCH3* intermediate and DMC product.
