We report a novel phase of carbon possessing monoclinic C2/m structure (8 atoms/cell) identified using an ab initio evolutionary structural search. This polymorph, which we call M-carbon, is related to the (2x1) reconstruction (111) surface diamond and can also be viewed as distorted (through sliding buckling sheets) form graphite. It stable over cold-compressed graphite above 13.4 GPa. The simulated x-ray diffraction pattern near K-edge spectroscopy are in satisfactory agreement with...
The lattice structure of monolayer borophene depends sensitively on the substrate yet is metallic independent environment. Here, we show that bilayer Ag(111) shares same ground state as its freestanding counterpart becomes semiconducting with an indirect bandgap 1.13 eV, evidenced by extensive structural search based first-principles calculations. composed two covalently bonded v1/12 boron monolayers are stacked in AB mode. interlayer bonds not only localize electronic states otherwise but...
Mass production of high-quality synthetic SAR training imagery is essential for boosting the performance deep-learning (DL)-based automatic target recognition (ATR) algorithms in an open-world environment. To address this problem, we exploit both widely used Moving and Stationary Target Acquisition Recognition (MSTAR) dataset Synthetic Measured Paired Labeled Experiment (SAMPLE) dataset, which consists selected samples from MSTAR their computer-generated counterparts. A series data...
In this research, acid hydrolyzed starch, B-type microcrystalline and amorphous starch were prepared from natural corn starch. X-ray diffraction (XRD) Raman spectroscopy used to analyze the structure of these four types starches. The spectrum scattering peaks have decreased vibration wave numbers because changes crystal type, intensity each peak is related size crystalline region. By identifying area in as region total under curve minus fluorescent sum regions, we established a useful method...
We investigate the electronic transport properties for a molecular device model constructed by phenylene ethynylene oligomer with different side groups embedding in carbon chain between two graphene electrodes. Using first-principles method, unusual dual conductance, negative differential resistance (NDR) behavior large peak to valley ratio, and obvious rectifying performance are numerically observed such proposed device. The analysis of projected self-consistent Hamiltonian evolution...
A hexagonal boron nitride monolayer with aligned orientations is grown on reusable semiconducting germanium. The number of primary the h-BN domains depends symmetry underlying crystal face, and Ge (110) gives rise to only two opposite orientations. structures electrical properties grain boundaries between are also systematically analyzed. As a service our authors readers, this journal provides supporting information supplied by authors. Such materials peer reviewed may be re-organized for...
Metalloborophene, characterized by the presence of metal-centered boron wheels denoted as M\c{opyright}Bn, has garnered considerable attention in recent years due to its versatile properties and potential applications fields such electronics, spintronics, catalysis. However, experimental verification metalloborophene been challenging, mainly unconventional two-dimensional (2D) networks. In this study, we employ scanning tunneling microscopy, X-ray photoelectron spectroscopy, low energy...
Abstract Borophene, a boron analogue of graphene, is typically metallic, while all bulk phases are insulating. Here, we predict by first‐principles calculations that recently synthesized bilayer borophene, being suggested to be composed two stacked v 1/12 sheets, semiconductor with bandgap 1.13 eV, almost the same as silicon. It shown stacking mode between sheets well density and pattern interlayer boron‐boron (B─B) bonds key factors for opening in otherwise metallic sheet. Moreover,...
Two dimensional crystals, befitting nanoscale electronics and spintronics, can benefit strain-tunable applications due to their ultrathin flexible nature. We show by first-principles calculations that tensile strain enhance the exchange splitting of spins in NbSe2 NbS2 single layers. Particularly, a switch from antiferro- ferro-magnetism is realized engineering. Under strains lower than 4%, an antiferromagnetic state with opposite aligned on next-nearest-neighbor rows Nb atoms favored energy...
Hydrogenated borophenes─borophanes─have recently been synthesized as a new platform for studying low-dimensional borides, but most of their lattice structures remain unknown. Here, we determine the borophane polymorphs on Ag(111) by performing extensive structural search using cluster expansion method augmented with first-principles calculations. Our results reveal rich whose stability depends hydrogen pressure. At relatively low pressures, rhombic patterns two-center-two-electron B-H bonds...
Excessive use of chemical fertilizer is a global concern. Arbuscular mycorrhizal fungi (AMF) are considered potential solution due to their symbiotic association with crops. This study assessed AMF's effects on maize yield, efficiency, plant traits, and soil nutrients under different reduced-fertilizer regimes in medium-low fertility fields. We found that phosphorus supplementation after 30% reduction enhanced positive impact grain increasing it by 3.47% pure fertilizers 6.65% mixed...
The interaction of water with nanostructured, functional carbon materials has led to fascinating phenomena, such as electricity induced by evaporation from black sheets evaporation. Here, we carry out a comprehensive ab initio study the charge-neutral and protonated molecules graphene oxides focus on typical epoxide, carbonyl, hydroxyl, carboxyl groups in sheets. These oxygen can greatly enhance both binding energy charge transfer between graphene. Among groups, group is most attractive...
The electronic, vibrational, and superconducting properties of $\mathrm{Y}{\mathrm{B}}_{6}$ with pressure have been extensively studied using the ab initio calculations. Fermi surface calculation indicates a pressure-induced electronic topological transition under compression. lattice dynamic study strongly suggests existence phase in high by evidence phonon softening behavior.

We report a high-pressure tetragonal PbO-type structure $(B10)$ of ZnO predicted through ab initio lattice-dynamics calculation. This can be directly transformed from NaCl $(B1)$ along an orthorhombic $Pmmn$ transition path and viewed as alternatively stacked layers cations anions with the anion layer composed zigzag arranged anionic rows. Enthalpy curve calculation suggests that $B10$ is stable in large pressure range 236--316 GPa, above which CsCl $(B2)$ takes over. Band-structure reveals...
