The crossover from localized to itinerant electron regimes in the geometrically frustrated spinel system ${\mathrm{Mn}}_{1\ensuremath{-}x}{\mathrm{Co}}_{x}{\mathrm{V}}_{2}{\mathrm{O}}_{4}$ is explored by neutron-scattering measurements, first-principles calculations, and spin models. At low Co doping, the orbital orde…
Conelike cross-linked PS particles are polymerized at a patchy emulsion interface. The PS particles synthesized in the dispersed paraffin phase immigrate toward the interface due to the Pickering effect. At the triple phase contact line, the particles are squeezed into cone shape under an outward convex interfacial te…
Forming good metal/graphene contact is of significance in making graphene devices, while tuning the graphene work function is a valid approach to decrease the contact barrier and then achieve electrodes with low contact resistance. A strain device has been fabricated to apply uniaxial strain to graphene grown by chemi…
Alumina green bodies were shaped by slip casting under a strong magnetic field. Alumina ceramics were obtained by hot isostatic pressing (HIP) at 1275°C and pressureless sintering at above 1700°C, respectively. HIP-sintered alumina, with in-line transmittance of 52% at 600nm and 82% at 2μm, showed a sub-micrometer gra…
Abstract The reaction of antimony and selenium in the Lewis‐acidic ionic liquid 1‐butyl‐3‐methyl‐imidazolium tetrachloridoaluminate, [BMIm]Cl · 4.7AlCl 3 , yielded dark‐red crystals of [Sb 2 Se 2 ]AlCl 4 . The formation starts above 160 °C; at about 190 °C, irreversible decomposition takes place. The compound crystall…
Synthetic and natural polymer association is a promising tool in tissue engineering. The aim of this study was to compare five methodologies for producing hybrid scaffolds for cell culture using poly-l-lactide (PLLA) and collagen: functionalization of PLLA electrospun by (1) dialkylamine and collagen immobilization wi…
The electrocaloric effect was observed in association with an electric-field induced metal-insulator transition in VO2 using a calorimetric measurement under an applied voltage. For a VO2 plate with a 0.4 mm thickness located in the center of a capacitor-like structure, the metal-insulator transition was manipulated b…
We study the growth of epitaxial graphene nanoribbons on silicon carbide mesa sidewalls by means of scanning probe techniques, local transport, and Raman spectroscopy. The sidewall nanoribbons are demonstrated to consist of charge neutral monolayer graphene with a zig-zag type orientation. Two types of roughness, the…
Using first-principles calculations, we investigate the geometric structures and electronic properties of porous silicene and germanene nanosheets, which are the Si and Ge analogues of α-graphyne (referred to as silicyne and germanyne). It is found that the elemental silicyne and germanyne sheets are energetically unf…
Flower-like particles (FLPs) with hierarchical surface architectures have recently attracted considerable attention due to their potentially wide application range. Hitherto, nearly all FLPs were fabricated using inorganic compounds, while versatile organic polymers have not received sufficient attention yet. Herein,…
Hexagonal boron nitride nanosheets (BNNSs) were prepared by a facile chemical exfoliation method. Then cosolution film casting method was used to obtain poly(butylene adipate) (PBA)/BNNSs nanocomposites. The incorporated BNNSs changed the formation condition of the polymorphic crystals of PBA. The results of different…
Classical podzolization studies assumed vertical percolation and pedon-scale horizon development. However, hillslope-scale lateral podzolization also occurs where lateral subsurface water flux predominates. In this hydropedologic study, 99 podzols were observed in Watershed 3, Hubbard Brook Experimental Forest, New Ha…
Investigations on the transformation of selenidostannates in ionic liquids were extended by using ternary P1-type cluster precursors [M4Sn4Se17](10-) [M = Mn (1), Zn (2), Cd (3)], which were synthesized for the first time as their Cs(+) salts. Treatment of 1 with 1,2-diaminoethane (en) in [BMIm][BF4] yielded two-dimen…
In this review, recent developments in the fabrication of hexagonal and parallel ordered arrays of metallic nanodomains on a substrate are described. We focus on the nanopatterning approach by means of switchable block copolymer thin films. This approach is highly advantageous, because it can lead to extremely regular…
PbTiO3 thin films were epitaxially grown on (001) KTaO3 single crystal substrates by metalorganic chemical vapor deposition. The coherent epitaxial growth introduced a large in-plane tensile strain to the PbTiO3 film. This tensile strain increased TC and directed the polarization to one of the in-plane ⟨100⟩ axes belo…
Surface structure is of special significance to the heterogeneous catalysis, because catalysis is primarily a surface phenomenon. Therefore, a comprehensive understanding of the relationship between the catalytic activity and surface structure is of great importance. Herein, hierarchical FeWO 4 architectures assembled…
Type I collagen is the main structural component of skin, tendons, and skin products, such as leather. Understanding the mechanical performance of collagen fibrils is important for understanding the mechanical performance of the tissues that they make up, while the mechanical properties of bulk tissue are well charact…
The perovskite PbCrO3 is an antiferromagnetic insulator. However, the fundamental interactions leading to the insulating state in this single-valent perovskite are unclear. Moreover, the origin of the unprecedented volume drop observed at a modest pressure of P = 1.6 GPa remains an outstanding problem. We report a var…
The overprints produced in inkjet technology with graphene oxide dispersion are presented. The graphene oxide ink is developed to be fully compatible with standard industrial printers and polyester substrates. Post-printing chemical reduction procedure is proposed, which leads to the restoration of electrical conducti…
Tunable electromagnetic properties of pristine two-dimensional boron phosphide (h-BP) nanosheet and its semihydrogenated structure were studied by density functional theory computations. In sharp contrast to previously reported tensile strain-induced red shift in two-dimensional semiconductors, the direct gap of h-BP…
