We work on RD‐spaces 𝒳 , namely, spaces of homogeneous type in the sense Coifman and Weiss with additional property that a reverse doubling holds . An important example is Carnot‐Carathéodory space measure. By constructing an approximation identity bounded support type, we develop theory Besov Triebel‐Lizorkin underlying spaces. In particular, this includes Hardy H p ( ) local h RD‐spaces, which appears to be new setting. Among other things, give frame characterization these function spaces,...

Abstract The dendritic structure is a disastrous problem of lithium metal batteries as well other rechargeable batteries. structures are usually caused by diffusion limitation. Here, novel strategy reported to inhibit dendrites based on the understanding their formation mechanism. An alternating current field perpendicular anode set up, which promotes Li + movement along surface and prevents ions' deposition tips from forming dendrites. Furthermore, an external direct parallel employed,...

Here we report a strategy to enhance the energy density of supercapacitors by increasing utilization rate specific surface area (SSA) via wettability improvement. The nonporous gold (NPG) film is used as electrodes and ionic liquid [EMIM]BF4 electrolyte. When electrode coated paraffin, an increase contact angle leads remarkable reduction capacitance. While when acetonitrile added into electrolyte, decreased SSA improved, which results in addition isopropyl acetate electrolyte further To...

Geometric structure and chemical composition are two critical factors that determine the electronic properties of an active metal favorable for a given catalytic reaction. In this scenario, we develop wet-chemistry method to construct core–shell nanoentities consisting CuPd alloy core NiPd shell, termed as CuPd@NiPd, which involves synthesis CuNi seeds, subsequent galvanic replacement reaction with Pd2+ precursors in organic medium at elevated temperature. these unique nanostructures,...

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 +...

Abstract Let (𝒳, d , μ ) be a space of homogeneous type in the sense Coifman and Weiss. Assuming that satisfies certain estimates from below there exists suitable Calderón reproducing formula L 2 (𝒳), authors establish Lusin‐area characterization for atomic Hardy spaces H p at (𝒳) Weiss ∈ ( 0 1], where = n /( + ε 1 depends on “dimension” 𝒳 “regularity” formula.

The diffusion and reaction are two general kinetic factors playing an important role in the structure development of materials. Upon limitation, a noncompact is easily formed, while compact usually formed reaction-limited condition. In this Article, we take precipitation calcium carbonate as example to discover roles shaping particles. By adjusting three-cell reactor, synthesize snow-shaped particles, which new morphology carbonate. microscopic characterization shows that microparticle...
