The strong interface is an essential requirement to ensure the effective load transfer of graphene/Cu composites. Here we attempted improve adhesion and mechanical properties reduced graphene oxide (RGO)/CuCr composites by matrix-alloying with ∼0.2 at.% Cr. It was found that a trace amount Cr7C3 layers/nanoparticles in-situ formed at RGO-CuCr interface, which contributed dramatically improved interfacial bonding 2.5 vol% RGO/CuCr composite exhibited tensile strength 352 MPa, 82% 19% higher...
Abstract Flexible Zn‐ion batteries (ZIBs) emerge as a promising entrant for flexible and safe energy systems in the post‐Li era, while instability of Zn anode including inferior flexibility, uncontrollable plating, dendrite growth remains challenge. Naturally inspired, topology‐optimized biomimetic honeycomb (BH‐Zn) through mechanical‐electrochemical processing is demonstrated. Numerical simulations experimental observations reveal BH‐Zn engenders smooth current–stress–thermal field...
Abstract Electrocatalytic N 2 reduction reaction (NRR) provides a sustainable approach for ambient fixation. Non‐noble transition metal‐based electrocatalysts (TMEs) are emerging as the most promising NRR catalysts, but commonly exhibited limited activity. Heteroatom doping is an effective method to improve electrocatalytic activity of TMEs by finely modulating electronic structures. Herein, proof‐of‐concept, nitrogen‐doped NiO nanosheet array on carbon cloth (N‐NiO/CC) was investigated...
By anti-oxidative electrolyte solvent regulation, we effectively regulated the reaction path of PF 6 − anions in Helmholtz plane LCO/electrolyte interface at 4.6 V, forming a robust CEI and retaining layered structure LCO with cycling.
Abstract For LiCoO 2 (LCO) operated beyond 4.55 V (vs Li/Li + ), it usually suffers from severe surface degradation. Constructing a robust cathode/electrolyte interphase (CEI) is effective to alleviate the above issues, however, correlated mechanisms still remain vague. Herein, progressively reinforced CEI realized via constructing Zr─O deposits (ZrO and Li ZrO 3 ) on LCO (i.e., Z‐LCO). Upon cycle, these can promote decomposition of LiPF 6 , convert highly dispersed Zr─O─F species. In...
Single-crystalline Ni-rich layered oxides are one of the most promising cathode materials for lithium-ion batteries due to their superior structural stability. However, sluggish diffusion kinetics and interfacial issues hinder practical applications. These intensify with increasing Ni content in ultrahigh-Ni regime (≥90%), significantly threatening viability single-crystalline strategy oxide cathodes. Herein, by developing a high-entropy coating strategy, we successfully constructed an...
Late Paleozoic sedimentary environments and the associated paleogeography of SW Yangtze block South China are critical for understanding formation bauxite clay-type Li deposits, which in turn provide insights into tectonic evolution East Asia. However, there is a lack consensus on provenance these deposits. Analysis rock assemblages structures shows that Devonian to Permian sediments Central Yunnan basin dominated by siliciclastic carbonate rocks indicative deposition coastal tidal...
Abstract The cathode‐electrolyte interphase (CEI) is vital for the stability of LiCoO 2 (LCO) beyond 4.55 V (vs Li/Li + ). Herein, full coverage boron‐based CEI achieved on LCO surface via utilizing self‐wetting synthesis boric acid (i.e., B‐LCO), accompanying with subsequent electrochemical self‐assembly process upon cycles. Initially, B‐LCO coated borate deposits (size 10–20 nm), then it melts and fully covers sintering, leading to artificial CEI, which directly reduces side reactions...
Neuromorphic systems consisting of artificial neurons and synapses can process complex information with high efficiency to overcome the bottleneck von Neumann architecture. Artificial are essentially required possess functions such as leaky integrate-and-fire output spike. However, previous reported typically have operation voltage large leakage current, leading significant power consumption, which is contrary energy-efficient biological model. Here, an oscillatory neuron based on Ag...
Gas sensors with multiselectivity are drawing increasing attention and temperature-tuned dual selectivity have been developed. Because Au nanoparticles (NPs) can lower the activation barrier for sensing reactions, herein, NP decoration was used to expand range of a ZnO nanotetrapod (NTP)-based sensor. A triselectivity sensor based on NP–ZnO NTPs The exhibited enhanced formaldehyde when operation temperature <200 °C, ethanol between 200 340 acetone >400 °C. Additionally, increased magnitude...
Mercury intrusion porosimetry (MIP) is questioned for possibly damaging the micro structure of cement-based materials (CBMs), but this theme still has a lack quantitative evidence. By using X-ray computed tomography (XCT), study reported an experimental investigation on probing pore damages in paste and mortar samples after standard MIP test. XCT scans were performed before mercury intrusion. Because its very high mass attenuation coefficient, can greatly enhance contrast images, paving path...
