Lithium–sulfur (Li–S) batteries have now emerged as the next-generation rechargeable energy storage system because of high density and theoretical capacity. However, notorious "lithium polysulfide (LiPS) shuttle" sluggish kinetics in sulfur redox posted great threat to their practical applications. Herein, we develop a VN-modified separator an effective promoter regulate LiPSs accelerate electrochemical Li–S batteries. Benefiting from dense packing structure polar surface porous VN,...
Intercalated transition metal dichalcogenides (TMDs) have attracted substantial interest due to their exciting electronic properties. Here, we report a unique approach where copper (Cu) atoms from bulk Cu solid intercalate spontaneously into van der Waals (vdW) gaps of group IV and V layered TMDs at room temperature atmospheric pressure. This distinctive phenomenon is used develop strategy synthesize species-intercalated TMD compounds. A series Cu-intercalated 2H-NbS2 compounds were obtained...
The Mg/S battery is attractive because of its high theoretical energy density and the abundance Mg S on earth. However, development hindered by lack understanding to underlying electrochemical reaction mechanism charge-discharge processes. Here, using a unique in situ X-ray absorption spectroscopic tool, we systematically study pathways cells Mg(HMDS)2-AlCl3 electrolyte. We find that capacity degradation mainly due formation irreversible discharge products, such as MgS Mg3S8, through direct...
Abstract Rechargeable magnesium/sulfur (Mg/S) batteries are widely regarded as one of the alternatives to lithium‐ion batteries. However, a key factor restricting their application is lack suitable electrolyte. Herein, an electrolyte additive that can reduce polarization voltage developed and 98.7% coulombic efficiency realized. The as‐prepared Mg‐ion exhibits excellent Mg plating/stripping performance with low overpotential 0.11 V for plating process, high anodic stability up 3.0 (vs Mg/Mg...
A high-valence-cation doped MoS<sub>2</sub>/MoO<sub>2</sub> hetero-electrocatalyst incorporated in carbon nanotube foam by a one-step synthesis synergistically enhances the HER activity.
With the aim of broadening scope Janus-type polymers with new functionalities, miktoarm star copolymers comprising helical poly(phenyl isocyanide) (PPI) and a vinyl polymer were designed synthesized via combination Pd(II)-initiated isocyanide polymerization atom transfer radical (ATRP). A functional β-cyclodextrin bearing 7 Pd(II) complexes at one side 14 bromine groups other ((Pd(II))7-CD-(Br)14) was prepared used as an initiator for one-pot phenyl ATRP monomers in living controlled manner....
Recently, alloys have been widely utilized as protection layers for homogenized Li growth. However, the protective mechanisms different are not clearly understood. Herein, guided by binary phase diagrams, Mg, Au, Zn, Al, Fe, and Cu selected study of their abilities mechanisms. The metals can be classified into three categories according to nature associated alloy layers: (1) with high solubility in while forming any intermediate line compounds, e.g., which is good fast stripping; (2) limited...
Abstract The direct synthesis of dimethyl carbonate (DMC) from CO 2 and methanol is an attractive approach based on green chemistry. influence the addition 2,2‐dimethoxy propane (DMP) DMC formation was investigated over spindle‐CeO , cube‐CeO octahedron‐CeO . Among these catalysts, showed a more favorable catalytic performance than other CeO catalysts for with DMP. yield greatly improved by in situ removal water reaction system through This indicated that hydrolysis DMP overcomes...
The specific surface area and pore structure of carbon materials significantly impact their electrochemical performance.
Optically active helical polycarbenes with methyl salicylate substituents were obtained by a helix-sense-selective polymerization strategy and their postpolymerization modification was investigated.
Abstract Allergy to nickel based alloy arch wires, which is largely induced by corrosion behavior, can cause severe problems during the orthodontic treatment. However, no consensus has been reached in comparison of anti-corrosion behavior between Nickel-Titanium (NiTi) and Copper (CuNiTi) wires. Herein, NiTi CuNiTi wires was simultaneously studied artificial saliva under loading stress simulate clinical conditions. Scanning electron microscope (SEM) utilized detect surface morphology...
Particulate matter emitted by internal combustion engines is one of the main sources air pollution. Oxygenated fuels can partially replace diesel fuel in and reduce emission level, especially particulate engines. In this paper, particles from dimethyl carbonate (DMC)/diesel blends with different blending ratios were collected, effects DMC on morphology analyzed via scanning electron microscopy small-angle X-ray scattering (SAXS) a synchrotron radiation source. By studying intensity, particle...
