A FeCo-Se@NiCo-PO Electrode Designed by Hierarchical Strategy for Supercapacitors and NiCo//Bi Batteries.

In this work, FeCo-Se and NiCo-PO were electrodeposited on nickel foam (NF) successively to prepare a cathode material for asymmetric supercapacitors (ASCs) and NiCo//Bi batteries. FeCo-Se@NiCo-PO combines the advantages of transition metal selenides (TMSs) and transition metal phosphates (TMPs). FeCo-Se electrodeposited in the underlying layer can facilitate electron transfer for higher conductivity.

Design of super stretchability, rapid self-healing, and self-adhesion hydrogel based on starch for wearable strain sensors.

Since hydrogels are conductive, easily engineered, and sufficiently flexible to imitate the mechanical properties of human skin, they are seen as potential options for wearable strain sensors. However, it is still a great challenge to prepare a hydrogel through simple and straightforward methods that integrate excellent stretchability, ionic conductivity, toughness, self-adhesion, and self-healing. Herein, an acrylamide/3-acrylamide phenylboronic acid cross-linked network is modified to produce a semi-interpenetrating cross-linked hydrogel in just one easy step by adding starch.

Chiral Inorganic Polar BaTiO/BaCO Nanohybrids with Spin Selection for Asymmetric Photocatalysis.

Chirality-dependent photocatalysis is an emerging domain that leverages unique chiral light-matter interactions for enabling asymmetric catalysis driven by spin polarization induced by circularly polarized light selection. Herein, we synthesize chiral inorganic polar BaTiO/BaCO nanohybrids for asymmetric photocatalysis via a hydrothermal method employing chiral glucose as a structural inducer. When excited by opposite circularly polarized light, the same material exhibits significant asymmetric catalysis, while enantiomers present an opposite polarization preference.

Enhancing substrate specificity of microbial transglutaminase for precise nanobody labeling.

transglutaminase (smTG) can be used for site-specific labeling of proteins with chemical groups. Here, we explored the use of modified smTG for the biosynthesis of nanobody-fluorophore conjugates (NFC). smTG catalyzes the conjugation of acyl donors containing glutamine with lysine-containing acceptors, which can lead to non-specific cross-linking.

Research on cross regional green certificate bilateral distributed robust trading strategy based on Bayesian theory.

To ensure the effective implementation of the compulsory green certificate transaction in China, a multi-participant cross-regional green certificate bilateral transaction model considering the relevant technical characteristics of the unit is proposed to solve the problems such as the mismatch between the supply and demand of green certificates and the reduction of the transaction plan by the grid operation constraints in the current green certificate transaction. To mobilize the initiative of participants, the model adopts the bilateral transaction of free negotiation. To balance the interests of transaction participants, the paper analyzes the complex interaction of multi participants in cross-regional bilateral transactions by using cooperative game theory.

Metal-Organic-Framework-Derived CuO-ZnO@CN Hollow Nanoreactors: Precise Structural Control and Efficient Catalytic Performance.

Hollow carbon-nitrogen nanoreactors constitute a class of porous materials that have widespread application owing to their large inner cavities, low densities, core-shell interfaces, and enrichment effects. Direct carbonization of precursors is the simplest and most economical method to prepare porous carbon-nitrogen materials; however, this method requires high temperatures, thus yielding nonoxide structures. In this study, CuO-ZnO@CN (CN: carbon-nitrogen layers) is prepared using the two-step heating of zeolitic imidazolium skeleton-8 (ZIF-8) coated with CuO-ZnO precursors.

Comediating Adsorption and Electron Transfer via Dual-Active Site Catalyst Construction for Improving the Treatment of Extraction Wastewater.

Solvent extraction is widely applied, while extraction wastewater treatment remains a huge challenge because of the stability of extractants. Heterogeneous Fenton-like catalysis is a promising method, but the short half-life of hydroxyl radicals (⋅OH) generated by hydrogen peroxide (HO) activation results in unsatisfactory ⋅OH utilization and organics removal. Herein, an efficient strategy for treating extraction wastewater based on comediating adsorption and electron transfer by fluorine and nitrogen co-doped carbon (FNC) catalyst with dual-active site was developed.

Flexible Highly Thermally Conductive PCM Film Prepared by Centrifugal Electrospinning for Wearable Thermal Management.

Personal thermal management materials integrated with phase-change materials have significant potential to satisfy human thermal comfort needs and save energy through the efficient storage and utilization of thermal energy. However, conventional organic phase-change materials in a solid state suffer from rigidity, low thermal conductivity, and leakage, making their application challenging.
