A coupled-wave analysis of the particularly low-loss 0th- and -1st-order switching triggered by the +1st- and -2nd-order excitation of the surface plasmon of an undulated metal surface reveals that the cancelation of the -1st-order diffraction efficiency is due to the destructive interference between the field directl…
Abstract Novel bio‐based and biodegradable electrospun membranes, containing bactericidal ricinoleic acid (RA) units either by copolymerization with butylene succinate (BS) units or by blending PRA and PBS homopolymers, are characterized in their chemical, thermal, mechanical and surface properties. In the blends E. c…
Spandex is increasingly used in either every course or alternating courses of knitted fabrics to impart a greater level of stretch and form stability than that can be achieved with cotton alone. The incorporation of spandex to the fabric structure effects many of the fabric properties. In this study, 100% cotton, half…
We report catalyst-free growth of high-density single-sided ZnO nanocombs for the first time on a multi-layer graphene (MLG). Structural analysis based on scanning electron microscope reveals the nanocomb ribbon average diameter and length are about 90–600 nm and 5–60 μm, respectively, while the diameter and length of…
Spin polarization and stacking are interesting effects in complex molecular systems and are both presented in graphene-based materials. Their possible combination may provide a new perspective in understanding the intermolecular force. The nanoscale graphene structures with zigzag edges could possess spin-polarized gr…
A surface potential-based low-field drain current compact model is presented for two-dimensional (2D) transition metal dichalcogenide (TMD) semiconductor field-effect transistors that takes into account the effect of interface trap states on device current–voltage ( I ds – V gs ) characteristics and transconductance g…
We fabricated a series of mesoporous silicas and mesoporous organosilicates with hierarchical porosity through evaporation-induced self-assembly using Pluronic F127 as a template in this study. We could tailor the mesophase of each mesoporous silica sample by varying the weight ratio of its two silica sources: tetraet…
A continuum theory to describe periodic ripple formation in planar graphene/boron nitride superlattices is formulated. Due to the lattice mismatch between the two materials, it is shown that flat superlattices are unstable with respect to ripple formation of appropriate wavelengths. A competition between bending energ…
Low density polyethylene (LDPE)/ultrahigh molecular weight polyethylene (UHMWPE) and LDPE/poly(ethylene-co-vinylacetate) (EVA) blends were tested and compared with respect to their environmental stress cracking resistance (ESCR) using the Bell telephone test. The time to failure in the ESCR test improved with increasi…
We report the manipulation of spin-dependent splitting by geometric Doppler effect based on dielectric metasurfaces. The extrapolation of rotational Doppler effect from temporal to spatial coordinate gives the phase change when the local optical axes of dielectric metasurfaces are rotating in space. Therefore, the con…
We develop a general theoretical approach to describing the interaction of metamaterials with optical beams. The metamaterials are allowed to be anisotropic, chiral, noncentrosymmetric, and spatially dispersive. Unlike plane waves, beams can change their field distributions upon interaction with metamaterials, which c…
Copper sulfide nanocrystals (Cu 2– x S NCs) consisting of earth-abundant and nontoxic elements have attracted attention for optoelectronic and plasmonic applications due to their tunable light absorption and emission properties. In this work, we present a study of the electronic changes induced in organic-capped Cu 2–…
Shellac is being used in food, pharmaceutical, and agricultural industries. It is seldom used for biomedical applications due to its poor mechanical property and instability. We designed thermoresponsive shellac-based bioactive nanofiber mats that mimic extracellular matrix to extend their utility in wound healing. Va…
Trimethacrylate and dimethacrylate with rigid adamantane-like cores were synthesized from myo-inositol orthoester, and their radical homopolymerization and copolymerization with methyl methacrylate (MMA) were investigated. The radical homopolymerization of trimethacrylate yielded a networked polymer with higher therma…
The realization of long, aligned molecular wires is a great challenge, and a variety of approaches have been proposed. Interestingly, hexapentyloxytriphenylene (HAT5) discotic liquid crystal molecules, a model system of molecules with flat and aromatic cores, can spontaneously form well-aligned, micrometer long, yet o…
Abstract Low‐temperature selective catalytic reduction of NO from simulated flue gas by NH 3 on admixtures of iron ore and iron catalyst in a magnetically fluidized bed was experimentally studied. It was found that iron ore exerts a prominent catalytic effect on NO removal resulting in high removal efficiency without…
Abstract Porous zinc–manganese oxide (ZnMn 2 O 4 ) microstructures are prepared by calcination using a precursor method, and the material is successfully applied as the supercapacitor electroactive materials in a three‐electrode cell. Due to the unique micro/nanostructure, the as‐prepared sample obtained under the cal…
We present calculated structural and optical properties of molecular cadmium chalcogenide nonstoichiometric clusters with a size range of less than 1 nm to more than 2 nm with well-defined chemical compositions and structures in comparison to experimental characterization and previous theoretical work. A unified treat…
In high magnetic fields, the exciton absorption spectrum of a semiconducting single-walled carbon nanotube splits as a result of Aharonov-Bohm magnetic flux. A magnetic field of 370 T, generated by the electromagnetic flux compression destructive pulsed magnet-coil technique, was applied to single-chirality semiconduc…
Mesoporous silica nanoparticles have been widely investigated as drug delivery systems. The present study evaluated physical stability of indomethacin loaded mesoporous MCM-41 nanoparticles. The size, polydispersity index, zeta-potential, and drug loading degree of nanoparticles were determined immediately after their…
