The phonon dispersion of singly oriented graphene on Ir(111) has been determined by angle‐resolved inelastic electron scattering. Replica of graphene phonon bands are induced by the moiré superstructure. Calculations for a linear chain of C atoms attached to an infinitely heavy substrate reveal that imposing a superst…
Density functional calculations were preformed to investigate whether adding Ni into a Cu surface (denoted as Cu/Ni) or adding Cu into a Ni surface (Ni/Cu) is more efficient for catalyzing the water-gas shift (WGS)? The reactions of water dissociation and monoxide dissociation were selected to assess the activity and…
Large-scale simulations of two-dimensional bidisperse granular fluids allow us to determine spatial correlations of slow particles via the four-point structure factor ${S}_{4}(q,t)$. Both cases, elastic ($ϵ=1$) and inelastic ($ϵ<1$) collisions, are studied. As the fluid approaches structural arrest, i.e., for packi…
Scaling behaviour has been observed at mesoscopic level irrespective of crystal structure, type of boundary and operative micro-mechanisms like slip and twinning. The presence of scaling at the meso-scale accompanied with that at the nano-scale clearly demonstrates the intrinsic spanning for different deformation proc…
In this paper, organo-montmorillonite is introduced as new material for washing of denim garments in a conventional washing machine to produce old-look garments without prior desizing and post-chemical softening. Here, pumice stone replaced with organo-montmorillonite in denim washing to obtain desirable properties. T…
The energy density of an electrochemical capacitor can be significantly improved by utilizing a lithiated negative electrode and a high surface area positive electrode. During lithiation of the negative carbon electrode, the electrolyte reacts with the electrode surface and undergoes decomposition to form a solid elec…
The influence of the amount of alumina binders on the catalytic performance of Ni/HZSM-5 for hydrodeoxygenation of cyclohexanone was investigated in a fixed-bed reactor. N2 sorption, X-ray diffraction, H2-chemisorption and temperature-programmed desorption of ammonia were used to characterize the catalysts. It can be…
Differential scanning calorimetry (DSC), broadband dielectric (BDS), and Fourier transform infrared (FTIR) spectroscopies as well as theoretical computations were applied to investigate inter- and intramolecular interactions between the active pharmaceutical ingredient (API) indomethacin (IMC) and a series of acetylat…
Magnetic properties of the layered itinerant system ${\mathrm{Sr}}_{1\ensuremath{-}x}{\mathrm{Ca}}_{x}{\mathrm{Co}}_{2}{\mathrm{P}}_{2}$ were investigated under a magnetic field up to 70 T. As for the exchange-enhanced Pauli paramagnetic metal $\mathrm{Sr}{\mathrm{Co}}_{2}{\mathrm{P}}_{2}$, the magnetization curve sho…
The interactions of biomolecules such as amino acids with mineral surfaces in the near-surface environment are an important part of the short and long-term carbon cycles. Amino acid-mineral surface interactions also play an important role in biomineralization, biomedicine, and in assembling the building blocks of life…
A combination of computational and experimental methods was implemented to understand and confirm that conformational changes of a polymer [specifically polyacrylonitrile (PAN)] vary with the dispersion quality and confinement between single-wall carbon nanotubes (SWNT) in the composite fibers. A shear-flow gel-spinni…
We generalize the two-temperature model [Sanders and Walton, Phys. Rev. B 15, 1489 (1977)] for coupled phonon-magnon diffusion to include the effect of the concurrent magnetization flow, with a particular emphasis on the thermal consequence of the magnon flow driven by a nonuniform magnetic field. Working within the f…
The hierarchical architecture of protective biological materials such as mineralized fish scales, gastropod shells, ram's horn, antlers, and turtle shells provides unique design principles with potentials for guiding the design of protective materials and systems in the future. Understanding the structure-property rel…
This study reports the results of the characterization of cellulose acetate butyrate and polycaprolactone-triol blends in terms of miscibility, swelling capacity, mechanical properties, and inflammatory response in vivo. The cellulose acetate butyrate film was opaque and rigid, with glass transition (T g ) at 134℃ and…
Abstract Simultaneous twin polymerization was used to synthesize hybrid materials composed of tin oxide, silica, and a phenolic resin starting from a mixture of 2,2′‐spirobi[4 H ‐1,3,2‐benzodioxasiline] (Si‐spiro) with either the tin(IV) alkoxides 2,2′‐spirobi[4 H ‐1,3,2‐benzodioxastannine] ( A ), 2,2′‐spirobi[6‐methy…
Continuous advances in the field of bionanotechnology, particularly in the areas of synthesis and functionalization of colloidal inorganic nanoparticles with novel physicochemical properties, allow the development of innovative and/or enhanced approaches for medical solutions. Many of the present and future applicatio…
Control of the dispersion and size of metallic nanoparticles, as well as metal–support interaction, is of vital importance to enhance the catalytic performance of supported metal nanocatalysts. In this work, carbon-supported boron-promoted Ni nanocatalysts (B–Ni) were synthesized via an in situ self-reduction process…
Five 9,10-bis((4-N,N-dialkylamino)styryl) anthracene derivatives (DSA-C1-DSA-C7) with different length alkyl chains were synthesized. They showed the same color in dilute solutions but different colors in crystals. The absorption, photoluminescence, and fluorescence decay indicate that there exist both excitonic and d…
The use of silver nanoparticles (AgNPs) in textiles for enhanced anti-microbial properties has led to concern about their release and impact on both human and environmental health. Here a novel method for in situ visualization of AgNP release from silver-impregnated wound dressings is introduced. By combining an envir…
Most late transition metal (LTM) monoxides crystallize in other than a rock salt structure, which is so common in the earlier transition metal monoxides. Here we present theoretical evidence based on density functional theory that an electron-phonon coupling involving a single soft mode in the cubic cell is responsibl…
