Abstract The initial oxidation of magnesium at oxygen partial pressures between 1.3 × 10 −8 and 1.3 × 10 −5 Pa and at temperatures ranging from 273 to 550 K has been investigated in situ with X‐ray photoelectron spectroscopy (XPS), ellipsometry and high resolution elastic recoil detection analysis (HERDA). Quantitativ…
The square-wave grating silica surfaces are fabricated by soft embossing silica sol-gel precursor on glass substrates with an elastomeric polydimethylsiloxane mold. The patterned silica surface could induce the planar alignment of liquid crystal 4-n-pentyl-4′-cyanobiphenyl (5CB) along the direction of microgrooves but…
Abstract In this research, the thermoresponsive composite latex particles were prepared via W/O miniemulsion polymerization. Fe 3 O 4 nanoparticles were homogeneously dispersed inside the poly(NIPAAm‐ co ‐MAA) latex particles. In the first step, PAA oligomers were used as stabilizers to produce a stable water‐based Fe…
The photoconductivity of carbon nanotube (CNT) Schottky barrier transistors is studied by solving the nonequilibrium Green’s function transport equation. The model provides a detailed and coherent picture of electron-photon coupling and quantum transport effects. The photocurrent shows peaks at photon energies near th…
During dyeing, dispersive flow is assumed to reduce the concentration gradient of dye liquor flowing through a yarn package, resulting in a more even distribution of dye in the liquor within the package. However, little is known about the degree of significance of dispersive transport, as a proportion of the total tra…
Abstract The effective storage time (i.e., storage life) of raw natural rubber (NR) was investigated with heat‐accelerated storage aging combined with thermogravimetry (TG) and differential thermal analysis (DTA) method, as well as the heat aging life equation. The test results show that the effective storage time of…
Abstract Polychelates were synthesized by the addition of aqueous solutions of copper(II), cadmium(II), and nickel(II) chlorides to aqueous solutions of poly(maleic anhydride‐ alt ‐acrylic acid) [poly(MA‐ alt ‐AA)] in different pH media. The thermal properties of poly(MA‐ alt ‐AA) and its metal complexes were investig…
Here we report the synthesis of silicon doped boron carbide (Si-doped B4C) nanorods via a solid reaction using activated carbon, boron, and silicon powder as reactants. These nanorods have been studied by high-resolution transmission electron microscopy, scanning electron microscopy, electron energy loss spectroscopy,…
A tall barrier superlattice structure based on mercury cadmium telluride material system is proposed that can achieve a large effective thermoelectric figure of merit (ZTmax∼3) at cryogenic temperatures. Calculations based on the Boltzmann transport equation taking into account the quantum mechanical electron transmis…
We have reported the formation of ZnO nanoparticles and α-AgI nanocrystals embedded in the glass matrix in the 0.70AgI–0.15Ag2O–0.15[xZnO–(1−x)MoO3], x=0.05–0.30, glass nanocomposites from x-ray diffraction, field emission scanning electron microscopy, and high resolution transmission electron microscopy patterns. Fou…
Abstract Nanosize CaSO 4 and Ca 3 (PO 4 ) 2 fillers were synthesized with an in situ deposition technique, and their sizes were confirmed by X‐ray diffraction. CaSO 4 was prepared in 12‐ and 22‐nm sizes, and Ca 3 (PO 4 ) 2 was prepared in 13‐ and 24‐nm sizes. Experimental variables, such as torque, shear viscosity, sh…
ZnO ∕ CoZnO core-shell nanowires have been synthesized by depositing an epitaxial layer of CoxZn1−xO (x=0.05−0.25) onto single-crystalline ZnO nanowires via pulsed-laser deposition. Detailed material analysis confirmed the core-shell structure and revealed a homogeneous distribution of Co atoms in the ZnO lattice. Fie…
Abstract During dynamic vulcanization of polypropylene (PP)/ethylene–propylene–diene terpolymer (EPDM) blends with dicumyl peroxide/triallyl cyanurate, there is a possibility of the generation of in situ graft links at the interface. Three potential compatibilizers (PP‐grafted EPDM, styrene–ethylenebutylene–styrene, a…
Abstract The influences of organically modified montmorillonite (MMT) on morphology, crystallization behaviors of maleic anhydride grafted polyethylene (mPE) are investigated by using wide angle X‐ray diffraction (WAXD), transmission electron microscopy (TEM), differential scanning calorimetry (DSC), polarized optical…
Abstract Silk and wool are well‐known protein‐based fibers. Their environmental stability, biocompatibility, and unique mechanical properties provide an important basis for using these natural proteins in biomedical applications. To use them as biomaterials in the form of fibers, films, or membranes, it is necessary t…
Abstract Micromachining of chemical reactors enables the manufacture of microchannel reactors with unsually large surface‐to‐volume ratios. This can strongly affect the coupling between heterogeneous (wall) reactions and homogeneous (gas‐phase) reactions, ultimately leading to a complete quenching of homogeneous react…
Abstract We developed a conductive epoxy/amine system containing polyaniline doped with dodecylbenzenesulfonic acid (PAni.DBSA). The curing behaviors of diglycidyl ether of bisphenol A with triethylenetetramine (TETA), PAni.DBSA, and both amine compounds at different concentrations were investigated by differential sc…
Minimalist theories of complex systems are broadly of two kinds: mean field and axiomatic. So far, all theories of complex properties absent from simple systems and intrinsic to glasses are axiomatic. Stretched Exponential Relaxation (SER) is the prototypical complex temporal property of glasses, discovered by Kohlrau…
The conduction type of P doped ZnO thin films using Zn3P2 dopant source can be controlled by adjusting the oxygen partial pressure by means of radio-frequency sputtering. Under an optimal oxygen partial pressure of 5%, p-type ZnO thin films were obtained with a hole concentration of 1.93×1016–3.84×1019cm−3. Under a gr…
The significance of gate electrode processes to the transfer characteristics of electrochemical transistors is demonstrated using a device based on a polyacetylene ionomer. Two regimes of operation are identified. The first involves a conventional redox process where two Faradaic processes balance: oxidative doping of…
