Electrocatalytic hydrogen evolution reaction (HER) in alkaline solution is hindered by its sluggish kinetics toward water dissociation. Nickel-based catalysts, as low-cost and effective candidates, show great potentials to replace platinum (Pt)-based materials the media. The main challenge regarding this type of catalysts their relatively poor durability. In work, we conceive construct a charge-polarized carbon layer derived from quantum dots (CQDs) on Ni3N nanostructure (Ni3N@CQDs)...
Construction of cellular architectures has been expected to enhance materials' mechanical tolerance and stimulate broaden their efficient utilizations in many potential fields. However, hitherto, there have rather scarce developments boron nitride (BN)-type because well-known difficulties the syntheses BN-based structures. Herein, cellular-network multifunctional foams made interconnective nanotubular hexagonal BN (h-BN) are developed using carbothermal reduction-assisted situ chemical vapor...
Two-layer freestanding heterostructure consisting of VS2 monolayer and graphene was investigated by means density functional theory computations as a promising anode material for lithium-ion batteries (LIB). We have lithium atoms' sorption diffusion on the surface in interface layer VS2/graphene with both H T configurations monolayer. The theoretically predicted capacity heterostructures is high (569 mAh/g), barriers are considerably lower than bulk VS2, so that they comparable to graphitic...
The importance for the global carbon cycle, P–T phase diagram of CaCO3 has been under extensive investigation since invention high-pressure techniques. However, this study is far from being completed. In present work, we show existence two new polymorphs CaCO3. crystal structure prediction performed here reveals a polymorph corresponding to distorted aragonite and named aragonite-II. situ diamond anvil cell experiments confirm presence aragonite-II at 35 GPa allow identification another 50...
Metal-semiconductor hybrid nanomaterials are becoming increasingly popular for photocatalytic degradation of organic pollutants. Herein, a seed-assisted photodeposition approach is put forward the site-specific growth Pt on Au-ZnO particles (Pt-Au-ZnO). A similar was also utilized to enlarge Au nanoparticles at epitaxial (Au@Au-ZnO). An connection interface found be critical deposition or Au. Light on-off photocatalysis tests, utilizing thiazine dye (toluidine blue) as model compound, were...
The structural, magnetic and electronic properties of 2D VX2 (X = S, Se) monolayers graphene/VX2 heterostructures were studied using a DFT+U approach. It was found that the stability 1T phases is linked to strong electron correlation effects. study vertical junctions comprising graphene demonstrated interlayer interactions lead formation spin polarization both fragments while preserving linear dispersion graphene-originated bands. insertion Mo atoms between layers leads n-doping with...
NaCl is one of the simplest compounds and was thought to be well-understood, yet, unexpected complexities related it were uncovered at high pressure in low-dimensional states. Here, exotic hexagonal thin films on (110) diamond surface crystallized experiment following a theoretical prediction based ab initio evolutionary algorithm USPEX. State-of-the-art calculations experiments showed existence film, which due strong chemical interaction film with substrate.
Contrary to a wide-spread belief that alkali metal (AM) atoms intercalated into layered materials form single-layer structures only, recent experiments [Nature 564 (2018) 234] showed multi-layer configurations of lithium are possible in bi-layer graphene. Using state-of-the-art first-principles calculations, we systematically study the intercalation energetics for various AMs (Li, Na, K, Rb, Cs) graphene and MoS2. We demonstrate as host formation energy is negative Rb Cs only slightly...
The development of hydrogen energy is capable solving a number important issues that modern society facing, including global warming and various environmental impacts. Currently, there an intensive search for natural sources as well low-carbon techniques mass production from gas, associated petroleum water. In parallel, efforts to develop technologies the subsequent management are underway, creation its safe efficient storage one highest priority goals. For transportation today, solutions...
The role of proximity contact with magnetic oxides is particular interest from the expectations induced spin polarization and weak interactions at graphene/magnetic oxide interfaces, which would allow us to achieve efficient spin-polarized injection in graphene-based spintronic devices. A combined approach topmost-surface-sensitive spectroscopy utilizing metastable He atoms ab initio calculations provides direct evidence for effect junctions single-layer graphene half-metallic manganite...
Here, we demonstrate an improvement in sensitivity toward the NO2 analyte by varying width ratio of adjacent graphene oxide (GO) and reduced (rGO) layers using GO laser reduction technique. We evaluated changes brought material morphology, structure, electrical characteristics, sensing performance depending on GO/rGO ratio, which supported density functional theory calculations. Our results indicate that yields appearance a chemiresistive response to NO2. An optimum ensures high conductivity...
Single-walled carbon nanotubes (SWCNTs) are ideal channel material candidates for energy-efficient nanoscale transistors; however, it is challenging to achieve uniform alignment of semiconducting SWCNTs with homogeneous chirality. Here, we report the proof-of-concept using organized chirality-sorted via relay technique (ART), where iptycene molecules order through π–π interactions. Top-gated field-effect transistors (FETs) were fabricated aligned (10,3) chirality as channels show an ION 3.8...
The scaffolds made of polycaprolactone (PCL) are actively employed in different areas biology and medicine, especially tissue engineering.
