Abstract Stabilizing Li‐rich layered oxides without capacity/voltage fade upon cycling is a prerequisite for successful commercialization. Although the inhibition of structural and interfacial changes identified as an effective strategy, battery community always seeks technologically flexible method to make it really competitive among cathode. Herein, gradient W‐doping within Li 1.2 Mn 0.56 Ni 0.16 Co 0.08 O 2 (LLMO) proposed relieve crystal disintegration simultaneously enhance stability...
Abstract The low ion transport is a major obstacle for low‐temperature (LT) sodium‐ion batteries (SIBs). Herein, core‐shell structure of bismuth (Bi) nanospheres coated with carbon (Bi@C) constructed by utilizing novel Bi‐based complex (1,4,5,8‐naphthalenetetracarboxylic dianhydride as the ligand) precursor, which provides an effective template to fabricate anodes. At −40°C, Bi@C anode achieves high capacity, equivalent 96% that at 25°C, benefitting from nanostructured engineering and Na +...
Using MOFs as size-selection templates, we have for the first time synthesized atom-precise Au11:PPh3 nanoclusters (NCs) and Au13Ag12:PPh3 NCs with high purity by a one-step, in situ reduction method. Specifically, found that product released from frameworks of ZIF-8 is exclusively rather than polydispersed NCs, inside MIL-101(Cr) constitute exclusive product. The metal NC@MOF composites are also demonstrated catalytic application. efficiency oxidation benzyl alcohol indicates noble NCs@MOFs...
Nanoscale objects feature very large surface-area-to-volume ratios and are now understood as powerful tools for catalysis, but their nature nanomaterials brings challenges including toxicity nanomaterial pollution. Immobilization is considered a feasible strategy addressing these limitations. Here, proof-of-concept the immobilization of nanoscale catalysts in extracellular matrix bacterial biofilms, we genetically engineered amyloid monomers Escherichia coli curli nanofiber system that...
Abstract The damage of the solid electrolyte interphase (SEI) layer during stripping process in lithium secondary batteries causes reduction energy density. stabilization is as important inhibition dendrites for lithium‐based batteries. But former largely underestimated, which leads to unclear mechanism and lack effective solutions suppress damage. Here, this paper a diffusion‐limited SEI proposed. inhomogeneity results region‐dependent diffusion kinetics ions (Li + ) passing through layer....
Atomically dispersed nitrogen-coordinated transition metal (TM) anchored on graphene (TM–Nx–C) provides a promising potential for an electrochemical CO2 reduction reaction (CO2RR). However, it is still challenge to precisely control the electronic structures of TM single-atom catalysts (SACs) optimizing catalytic performance. Using first-principles calculations, we propose novel strategy regulate structure Ni–N4–C site by vertically coupling 3-fold N atom-coordinated atom (TM–N3–C) promoting...
A Heck-type alkylation of enamides with N-trifluoroethyl hydroxylamine reagents was developed under photocatalytic conditions. This stereoselective reaction provides amido-substituted (E)-α-trifluoromethyl allylamines in yields up to 96%. In the mechanism, photoredox-induced 1,2-H shift situ generated radical involved.
Hard carbon (HC) suffers from the issues of unsatisfactory sodium storage capacity and inferior rate performance, severely hindering its practical application. Enhancing slope commercial HC is considered an optimal strategy for improving performance. Bismuth metal well-known exceptional capability low-temperature Herein, we report effective approach regulating surface structure anodes by introducing bismuth nanoparticles increasing oxygen functional groups. Particularly, polyvinylpyrrolidone...
This letter reports on a contrast-based ultrasonic particle imaging technique (echo PIV) for measuring multicomponent velocity vectors in opaque flows with excellent temporal (up to 0.5ms) and spatial 0.4mm) resolution. Ultrasound contrast microbubbles are used as flow tracers, digitally acquired rf data converted into B-mode images PIV analysis. Here, fields from various patterns (including rotating transient vortex flows) that difficult measure using other methods such ultrasound Doppler...
We have recently developed an ultrasound-based velocimetry technique, termed echo particle image (Echo PIV), to measure multi-component velocity vectors and local shear rates in arteries opaque fluid flows by identifying tracking flow tracers (ultrasound contrast microbubbles) within these fields. The original system was implemented on images obtained from a commercial echocardiography scanner. Although promising, this limited spatial resolution measurable range. In work, we propose standard...
A recent global ban on the use of organotin compounds as antifouling agents has increased need for safe and effective compounds. In this study, a series new butenolide derivatives with various amine side chains was synthesized evaluated their anti-larval settlement activities in barnacle, Balanus amphitrite. Side chain modification resulted butenolides 3c-3d, which possessed desirable physico-chemical properties demonstrated highly non-toxic efficacy. structure-activity relationship analysis...
Compared with the inert metal (gold), active (Cd) is much more prone to oxidation, leading its high oxidation state. In this work, we found that doping homogold Au25(SR)18 nanocluster cadmium largely enhances stability. The differential pulse voltammetry (DPV) analysis suggested Cd raised occupied molecular orbital (HOMO) energy of Au25 nanocluster, which led stronger retention valence electrons. Cd1Au24(SR)18 also exhibited higher activity than in aerobic benzyl alcohol oxidation.
Sulfur/carbon composite were successfully fabricated by interfacial control strategy, superficial sulfur was effectively removed optimizing the ratio and amount of mixed solvents, thereby operating well in carbonate-based electrolytes.
A decarboxylative alkylation of enamides with alkyl diacyl peroxides induced by visible-light is described. The chemo-, regio- and stereoselective olefinic β-C-H generates a series primary- secondary alkylated in yields up to 95%. This transformation bears the advantages operational simplicity, good functional group compatibility mild conditions.
Polychloromethylative cyclization of N-alkenyl indoles was developed under metal-free conditions to afford tricyclic pyridoindolones and pyrroloindolones in moderate good yields. In the reaction, commercially available CHCl3 CH2Cl2 were employed as tri- dichloromethyl radical sources. Moreover, dichloromethylated polycyclic benzoimidazoles can also be obtained standard conditions.
