We have systematically investigated a metal-free bifunctional electrocatalyst of heteroatom-doped carbon nitride (XY-C3N4, where X and Y indicate the dopant doping site on C3N4, respectively) for oxygen evolution reduction reactions (OER ORR), considering possible reaction pathways based Eley–Rideal (ER) mechanism as well effects electrocatalytic activity. In this work, relative stability O* OOH* intermediates was key factor in determining ORR pathway; accordingly, follows two-step pathway...
A high performance B<sub>3</sub>S monolayer for LIB anode material with storage capacity, low OCV and Li diffusion energy barrier.
The progress of ecofriendly, clean, and sustainable energy resources always demands suitable anode materials for batteries with high structural stability superior storage capacity. Herein, we use density functional theory predictions to examine the potential features newly proposed planar membranes consist 5-, 6- 8- membered carbon rings, named as α- β-phographene (PhoG). Our calculations disclose that both β-PhoG structures possess structural, thermal, mechanical intrinsic metallic...
There is an increasing demand for control over the dimensions and functions of transition metal dichalcogenides (TMDs) in aqueous solution toward biological medical applications. Herein, approach exfoliation functionalization TMDs water via modulation hydrophobic interaction between poly(ε-caprolactone)-b-poly(ethylene glycol) (PCL-b-PEG) basal planes reported. Decreasing PCL length PCL-b-PEG from 5000 g mol-1 (PCL5000 ) to 460 (PCL460 significantly increases efficiency TMD nanosheets...
We systematically analyzed the relationship between structure and electrocatalytic activity of heteroatom-doped graphenes (GXs, where G X represent graphene heteroatom dopant) for hydrogen evolution reaction (HER).
The Li-ion conductivity is closely correlated with the uniformity of 4a- and 4c-cages in Li argyrodites. This a novel approach for tuning composition argyrodites “composition–structure–property” relationships.
Charge transport properties of organic semiconductors critically depend on their molecular packing structures. Controlling the charge by varying and understanding structure–property correlations are essential for developing high-performance electronic devices. Here, we demonstrate that carrier mobility in single-crystal nanowires can be modulated with respect to intermolecular center-to-center distance applying uniaxial strain cofacially stacked crystals. Monotonic changes (from 0.0196 19.6...
Abstract A transition metal dichalcogenide (TMD) based antioxidation platform is proposed, in which radical scavenging accomplished by the defect‐mediated one‐step hydrogen atom transfer (HAT) occurring on nanosheets water. To this end, TMD nanosheets, including MoS 2 , WS MoSe and WSe are finely dispersed water with aid of an amphiphilic poly(ε‐caprolactone)‐ b ‐poly(ethylene oxide) (PCL‐ ‐PEO) diblock copolymer that envelops a molecular layer less than 1 nm thickness. It then demonstrated...
Electrocatalysis is key to the development of several important energy and biosensing applications. In this regard, crystalline phase-dependent electrocatalytic activity materials has been extensively studied for reactions such as hydrogen evolution, oxygen reduction, etc. But comprehensive studies evaluating phase-dependence electrochemical have not undertaken. Herein, three phases (α-, β-, γ-) iron oxyhydroxide (FeOOH) synthesized characterized by spectroscopic microscopy techniques....
Suppression of Ni pop-up-initiated phase transition in an NCM 111 cathode by Zr-doping based on the understanding structural mechanism structure.
Metal–organic frameworks (MOFs), a new family of porous materials, have received great attention over the past several decades as potential materials for gas separation and storage, drug delivery. However, widespread use these has been seriously hampered by their susceptibility to moisture, which impacts sorption properties. Here, we explored properties titanium‐oxo cluster that can maintain in humid environment CO 2 capture H purification using Monte Carlo (MC) simulations density...
We systematically designed triaryl‐1,3,5‐triazine (TATZ) derivatives based on 2‐(4‐methoxyphenyl)‐4,6‐diphenyl‐1,3,5‐triazine through inner and outer hydroxyl (OH) group substitution analyzed their structures electronic transitions in order to design a new UV absorber type with anti‐UVA UVB functionality. In this work, we show that absorption efficiency can be controlled OH between 320–400 nm (UVA) 280–320 (UVB) due effect the HOMO levels of TATZ. Consequently, propose an optimal combination...
Since Earth-abundant materials have received considerable attention for energy applications, interest in developing new carbon-based structures actively continues. One such material, the 3D schwarzite structure, has unusual shape of Triply-Periodic Minimal Surfaces (TPMS) and shows a stable curvature formed carbon rings with more than six atoms. However, possibility application as catalytic material not been discussed, even though their geometric electronic features can improve reactivity...
The high ionic conductivity of argyrodite makes it an attractive candidate for solid-state electrolytes (SSEs) in all-solid-state Li-ion batteries (ASSBs). Although great effort has been devoted to using ab initio molecular dynamics (AIMD) evaluate and elucidate the diffusion mechanism argyrodite-based SSEs, limitations system size, simulation temperatures, time associated with AIMD make accurate predictions analysis challenging. Here, we present a reliable, large-scale computational...
From an in-depth understanding of the structural characteristics transition metal dichalcogenide (TMD) nanosheets, Sang Uck Lee, Jong-Ho Kim, Jin Woong and co-workers introduce a novel TMD-based antioxidation platform. As they report in article number 1802737, extraordinary antioxidant activity is derived from chalcogen defect-mediated hydrogen atom transfer aqueous media, even under harsh storage conditions wide span solution pH, sunlight exposure, elevated temperatures. This highlights TMD...
