Advanced aqueous phenazine redox flow battery enhanced by selective interfacial water behavior on Co/NC modified electrode.

Although aqueous organic redox flow battery (RFBs) is a highly promising energy storage device, the redox reaction kinetics of the anode organic electrolyte material, especially for phenazine derivatives, are limited by low electrochemical activity of traditional porous carbon electrodes. Herein, Co/NC composite electrocatalyst was elaborated to significantly enhance the redox reaction kinetics of phenazine derivatives, in which Co/NC electrocatalyst could improve energy efficiency of aqueous phenazine RFBs by 43.2 % compared to pure carbon felt electrodes at current density of 100 mA/cm.

Centromeric localization of αKNL2 and CENP-C proteins in plants depends on their centromere-targeting domain and DNA-binding regions.

In eukaryotes, accurate chromosome segregation during cell division relies on the centromeric histone H3 variant, CENH3. Our previous work identified KINETOCHORE NULL2 (αKNL2) as a plant CENH3 assembly factor, which contains a centromere-targeting motif, CENPC-k, analogous to the CENPC motif found in CENP-C. We also demonstrated that αKNL2 can bind DNA in vitro in a sequence-independent manner, without the involvement of its CENPC-k motif.

Effects of Vegetation Restoration Type on Soil Greenhouse Gas Emissions and Associated Microbial Regulation on the Loess Plateau.

Investigating responses of soil greenhouse gas (GHG) emissions to vegetation restoration is important for global warming mitigation. On the Loess Plateau, a wide range of vegetation restoration strategies have been implemented to control land degradation. However, the thorough quantification of soil GHG emissions triggered by different modes of vegetation restoration is insufficient.

Chitosaccharides (COS) is covalently bound with benzenboronic acid pinacol ester and assemble with cefoxitin sodium salt (CFS) to form COSBN@CFS nanoparticles.

Engineered DR/NIR dual-emission carbonized polymer dots for simultaneous tracking of lipid droplets and lysosomes.

Developing near-infrared fluorescent probes for simultaneous tracking of lipid droplets (LDs) and lysosomes is highly desirable for studying cell metabolism. In this work, deep-red/near-infrared dual-emission carbonized polymer dots (DN-CPDs) were prepared for ratiometric monitoring of the intracellular polarity. Detailed structural analysis revealed that the deep-red emission and near-infrared peak of DN-CPDs originate from the molecular state and surface state, respectively.

Redistribution of Electron Density for Promoting CO Conversion Capacity.

There is a need to design substrate-supported catalysts for the heterogeneous fields, especially with large porosity, which can facilitate mass transport. Herein, aiming at enhancing the performance of CO fixation, a hollow carbon sphere-supported catalyst of Fe/HCS (Fe, Fe nanoparticles; HCS, hollow carbon sphere) is facilely designed and fabricated. Excitingly, the experimental and calculation results reveal that Fe/HCS displays an ultrahigh activity with almost complete conversions in CO cycloaddition, surpassing the performance of Fe/CS (CS, carbon sphere); this demonstrates that the HCS plays a key role, which may be attributed to the hollow structure tuning the electron density and enhancing the enrichment of the substrate and CO, consequently lowering the barrier associated with mass transfer.

A Fusion Localization System for Security Robots Based on Millimeter Wave Radar and Inertial Sensors.

In smoggy and dusty environments, vision- and laser-based localization methods are not able to be used effectively for controlling the movement of a robot. Autonomous operation of a security robot can be achieved in such environments by using millimeter wave (MMW) radar for the localization system. In this study, an approximate center method under a sparse point cloud is proposed, and a security robot localization system based on millimeter wave radar is constructed.

Thermally and Electrically Regulated Plasmonic Devices Based on VO-Covered Gold Nanoplate Arrays with SiO Interface Layer for Large Plasmon Shifts.

Integrating metal nanoparticles with vanadium dioxide (VO) is an effective means to realize active plasmonic regulation which has great application potential in optical devices that respond in real-time to external stimuli. However, the high temperature necessary for VO growth severely reshapes the metal nanoparticles, causing reduced refractive index (RI) sensitivity and degraded modulation performance. Herein, we construct a large-area dynamically tunable plasmonic system composed of a VO-covered array of hexagonal gold nanoplates (AuNPLs).

Optimizing Interfacial Charge Dynamics and Quantum Effects in Heterodimensional Superlattices for Efficient Hydrogen Production.

Superlattice materials have emerged as promising candidates for water electrocatalysis due to their tunable crystal structures, electronic properties, and potential for interface engineering. However, the catalytic activity of transition metal-based superlattice materials for the hydrogen evolution reaction (HER) is often constrained by their intrinsic electronic band structures, which can limit charge carrier mobility and active site availability. Herein, a highly efficient electrocatalyst based on a VS-VS heterodimensional (2D-1D) superlattice with sulfur vacancies is designed addressing the limitations posed by the intrinsic electronic structure.

Observation of tunable accidental bound state in the continuum in silicon nanodisk array.

We experimentally demonstrate the tuning of accidental bound states in the continuum (A-BICs) in silicon nanodisk arrays. The A-BIC emerges of the destructive interference of multipoles, which are the dominating out-of-plane electric dipole and in-plane magnetic dipole, and weak electric quadrupole and magnetic quadrupole. We further show that the spectral and angular position of the A-BIC can be conveniently tuned by varying the nanodisk size or the lattice period.

Evolution from [Zn] to a record-high [Zn] subblock and engineering a hierarchical supramolecular framework for enhanced iodine uptake.

Hierarchical supramolecular frameworks are being designed and constructed for various applications, yet the controlled assembly and process understanding incorporating giant building blocks remains a great challenge. Here, we report a strategy of "rivet" substitution and "hinge" linkage for the controlled assembly of the hierarchical supramolecular framework. The replacement of two "rivet" ethylene glycol (EG) molecules for triangular prism [Zn] (a small block in 1) with a 1,3-propanediol (PDO) provides space for a "hinge" linkage from adjacent ligands, thus providing a hierarchical (from micro- to mesopores, from the internal cavity to external surface) supramolecular framework (2) based on a coordinative subblock with the record number of zinc ions ([Zn]).

Different contributions of crystalline and non-crystalline iron (hydr)oxides on the mobilization and thionation of diphenylarsinic acid in a flooded paddy soil.

Iron reduction impacts the mobilization and thionation of diphenylarsinic acid (DPAA) in soil, but the contribution of crystalline and non-crystalline iron remains unknown. A paddy soil deficient in non-crystalline iron (P-Fe), crystalline and non-crystalline iron (P-Fe) were incubated with sulfate-plus-lactate, and the results were compared with paddy soil (P) in our previous study. For treatments without ferrous sulfide (FeS) precipitation, the solution-to-solid ratio (R) of DPAA increased slightly and dramatically with iron reduction, respectively, for P-Fe and P, suggesting that the reduction of non-crystalline iron contributes more to DPAA mobilization than crystalline iron.

Elastomers have been widely employed in various industrial products such as tires, actuators, dampers, and sealants. While various methods have been developed to strengthen elastomers, achieving continuously high energy dissipation with fast room-temperature recovery remains challenging, prompting the need for further structural optimization. Herein, high energy dissipated and fast recoverable double-network (DN) elastomers are fabricated, in which the supramolecular polymers of complementary adenine and thymine serve as the first network and the covalently cross-linked soft polymer as the second network.
