Seeding 2D crystals Small, single are often used to direct the growth of larger, bulk crystals. Xu et al. modified these methods grow single-crystal films a two-dimensional (2D) semiconductor, 2H molybdenum ditelluride (2H MoTe 2 ), on an amorphous glass surface. After coating wafer with 1T′ film, small crystallite was placed wafer. The capped alumina except for hole above seed region that allowed entry additional tellurium during heating process drove phase transition and epitaxial ....
Despite relevance to disparate areas such as cloud microphysics and tribology, major gaps in the understanding of structures phase transitions low-dimensional water ice remain. Here, we report a first principles study confined 2D function pressure. We find that at ambient pressure hexagonal pentagonal monolayer are two lowest enthalpy phases identified. Upon mild compression, structure becomes most stable persists up ∼2 GPa, which point square rhombic stable. The agrees with recent...
The nature of hydrated proton on solid surfaces is vital importance in electrochemistry, channels, and hydrogen fuel cells but remains unclear because the lack atomic-scale characterization. We directly visualized Eigen- Zundel-type protons within bonding water network Au(111) Pt(111) surfaces, using cryogenic qPlus-based atomic force microscopy under ultrahigh vacuum. found that Eigen cations self-assembled into monolayer structures with local order, Zundel formed long-range ordered...
The refractive-lens technique has been well developed over a long period of evolution, offering powerful imaging functionalities, such as microscopes, telescopes, and spectroscopes. Nevertheless, the ever-growing requirements continue to urge further enhanced capabilities upgraded devices that are more compact for convenience. Metamaterial fascinating concept inspired unprecedented new explorations in physics, material science, optics, not only fundamental researches but also novel...
Abstract Construction of heterojunctions is an effective strategy to enhanced electrocatalytic oxygen evolution reaction (OER), but the structural active phases and synergistic mechanism still lack in‐depth understanding. Here, FeOOH/Ni 3 S 2 heterostructure supported on nickel foam (NF) through a two‐step hydrothermal‐chemical etching method reported. In situ Raman spectroscopy study surface reconstruction behaviors /NF indicates that Ni can be rapidly converted NiOOH, accompanied by phase...
Quantum effects in single hydrogen bonds Hydrogen are a combination of electrostatics with nuclear quantum contribution arising from the light mass nuclei. However, states nuclei extremely sensitive to coupling local environments, and these broadened averaged conventional spectroscopic or diffraction techniques. Guo et al. show that change strength individual water layers adsorbed on salt surface. These revealed inelastic tunneling spectra obtained chlorine-terminated scanning microscope...
Mammalian genomes encode a huge number of long noncoding RNAs (lncRNAs) with unknown functions. This study determined the role and mechanism new lncRNA, lncRNA suppressor hepatic gluconeogenesis lipogenesis (lncSHGL), in regulating glucose/lipid metabolism. In livers obese mice patients nonalcoholic fatty liver disease, expression levels mouse lncSHGL its human homologous B4GALT1-AS1 were reduced. Hepatic restoration improved hyperglycemia, insulin resistance, steatosis diabetic mice,...
Diffusion Monte Carlo (DMC) based on fixed-node approximation has enjoyed significant developments in the past decades and become one of go-to methods when accurate ground state energy molecules materials is needed. However, inaccurate nodal structure hinders application DMC for more challenging electronic correlation problems. In this work, we apply neural-network trial wavefunction DMC, which allows calculations a broad range atomic molecular systems different characteristics. Our method...
Water adsorption and dissociation processes on pristine low-index TiO2 interfaces are important but poorly understood outside the well-studied anatase (101) rutile (110). To understand these, we construct three sets of machine learning potentials that simultaneously applicable to various surfaces, based density-functional-theory approximations. Here show water free energies seven predict (100), (110), (001), (011) favor dissociation, (100) have mostly molecular adsorption, while simulations...
Abstract AlGaN‐based ultraviolet light‐emitting diodes (UV‐LEDs) have the advantages of mercury (Hg) pollution free, small size, high efficiency, and so on, are widely used in military, medical, industrial fields, which considered to be most promising alternative traditional Hg lamps. Great efforts made over past few decades improve device performance, thereby meeting commercial production application requirements UV‐LEDs, is always accompanied by a series interesting physical topics. In...
Abstract The epitaxial growth of molybdenum disulfide (MoS₂) on sapphire substrates enables the formation single‐crystalline monolayer MoS₂ with exceptional material properties a wafer scale. Despite this achievement, underlying mechanisms remain subject debate. interface is critical for understanding these mechanisms, yet its exact atomic configuration has previously been unclear. In study, grown substrate analyzed, decisively visualizing structure and elucidating role in from an...
Experiments and computer simulations have shown that the melt-ing temperature of solid hydrogen drops with pressure above about 65 GPa, suggesting a liquid state might exist at low temperatures. It has also been suggested this be non-molecular metallic, although evidence for such behaviour is lacking. Here, we report results high pressures using ab initio path-integral molecular dynamics methods, which include description quantum motion protons finite We determined melting as function by...
