In view of the diverse functional groups left on MXene during etching process, we computationally investigated effects surface-group types structural, electronic and optical properties Sc2CT2 (T = -O, -OH, -F) MXenes. For all geometries MXenes, geometry I Sc2CT2, which has locating above opposite-side Sc atoms, are lowest-energy structure. Accordingly, energetically favorable Sc2CF2-I, Sc2CO2-I Sc2C(OH)2-I were selected for further evaluation photocatalytic activities. We found that is...
Motivated by the successful synthesis of Janus monolayers transition metal dichalcogenides (i.e., MoSSe), we computationally investigated structural, electronic, optical, and transport properties functionalized MXenes, namely MM'CT2 (M, M' = Zr, Ti, Hf, M ≠ M', T -O, -F, -OH). The results calculations demonstrate that five stable O-terminated MXenes (ZrTiCO2-I, ZrHfCO2-I, ZrHfCO2-III, HfTiCO2-I, HfTiCO2-III), exhibit modest bandgaps 1.37-1.94 eV, visible-light absorption (except for...
Bimetallic nanomaterials, which exhibit a combination of the properties associated with two different metals, have enabled innovative applications in nanoscience and nanotechnology. Here, we introduce fabrication dendritic Au/Ag bimetallic nanostructures for surface-enhanced Raman scattering (SERS) catalytic applications. The were prepared by combining electrochemical deposition replacement reaction. formation Au nanoparticle shell on surface Ag dendrites greatly improves stability...
Searching for new two-dimensional (2D) Dirac cone materials has been popular since the discovery of graphene with a structure. Based on density functional theory (DFT) calculations, we theoretically designed HfB2 monolayer as 2D material by introducing transition metal Hf into graphene-like boron framework. This newly predicted pronounced thermal and kinetic stabilities along massless fermion Fermi velocities (3.59 × 105 6.15 m s-1) comparable to that (8.2 s-1). study enriches diversity...
Monodisperse Yttrium-doped BaTiO3 (YBT) nanoparticles with good crystallinity and uniform size distribution have been synthesised via a modified sol-hydrothermal method. The solubility of yttrium in BT was no more than 1 mol%. However, at higher Y3+ content, excess were inclined to form Y(OH)3 impurities, after high temperature sintering, impurity YBa3Ti2O8.5 can be detected the ceramics. Further, variation crystal volume indicated that preferred substitute for Ti4+ as an acceptor. FE-SEM...
Monolayer MnTe 2 stabilized as 1T structure has been theoretically predicted to be a two-dimensional (2D) ferromagnetic metal and can tuned via strain engineering. There is no naturally van der Waals (vdW) layered bulk, leaving mechanical exfoliation impossible prepare monolayer . Herein, by means of molecular beam epitaxy (MBE), we successfully prepared hexagonal on Si(111) under Te rich condition. Sharp reflection high-energy electron diffraction (RHEED) low-energy (LEED) patterns suggest...

In this paper we propose two quantum information splitting (QIS) schemes respectively for an unknown single-qutrit and single-ququart state via three pairs of two-qubit partially entangled state. The necessary measurements operations are given detailedly the success probabilities worked out. can be directly generalized to QIS multi-qutrit multi-ququart states by using Bell-states channel.
We propose a three-party scheme for quantum information splitting (QIS) of an arbitrary single-photon polarization state based on weak cross-Kerr nonlinearity combined with linear optics elements such as beam splitters (PBSs) and half wave plates (HWPs). The is generalized to the arbitrary-party case. With help nondemolition (QND) measurements, our schemes can be accomplished in almost deterministic way. two are feasible current technology.
The multidimensional structure, abilities of light-harvesting and charge-transfer, photothermal conversion semiconductor heterojunction are very important characters for high-performance photocatalysis. However, it remains a challenge to rationally design photocatalyst that meets the demand. Herein, plasmonic PbS/Cu2-xS/CdS polyhedral heterojunctions, which Cu2-xS CdS nanoparticles deposited on 24-faceted PbS, prepared efficient photothermal-assisted photocatalysis first time. Owing...
