Abstract In this article, the inhibition efficiency of imidazoline derivatives with different alkyl chain was investigated from aspect of diffusion using molecular dynamics method. The diffusion coefficient of three corrosive ions in the inhibitor membrane was proposed to evaluate the inhibition efficiency, and three…
Abstract A model is developed to describe thermally‐initiated polymerization of styrene between 100 and 170 °C. The model accounts for generation and consumption of styrene adduct. Chain transfer to adduct is the only transfer reaction used. Autoacceleration is modeled using the break‐point method of Hui and Hamielec.…
The p-type doping of ZnO is the key to ZnO-based light-emitting devices and has proven to be difficult. ZnO nanowires (NWs) are an ideal platform for the study of p-type doping due to their high crystal quality and easy growth. In this Article, we demonstrate an innovative approach via the combination of thin-film and…
Selective single-crystal growth of clathrate-I K 7.5 Si 46 and clathrate-II K 17.8 Si 136 was achieved from the precursor K 4 Si 4 by reaction of the vapor phase with spatially separated graphite in a closed volume under pressure. K 7.5 Si 46 was prepared at a temperature of 550 °C, and K 17.8 Si 136 was prepared at 6…
Abstract Diamond films were synthesized with up to 50% argon in the gas phase using high power plasma‐assisted chemical vapour deposition (PACVD). This resulted in a strong increase of the deposition rates. Polycrystalline diamond (PCD) films grown with Ar have shown a higher incorporation of sp 2 phases but with no d…
Two polyoxometalate-based silver(I) compounds including a three-dimensional porous crystalline array and a double-helicate bisupporting cluster were achieved using metal-organic helicates and Keggin [PMo(12)O(40)](3-) as secondary building blocks.
Recently, the ferroelectric Eu${}_{0.5}$Ba${}_{0.5}$TiO${}_{3}$ was suggested for experimental searches of the electron electric dipole moment. To analyze results of the experiment and interpret them in terms of fundamental constants, the effective electric field ${E}_{\mathrm{eff}}$ acting on unpaired electrons of th…
Abstract A new dysprosium(III) cluster, namely [Dy 6 III ( L ) 4 (μ 3 ‐OH) 4 (CH 3 OH) 2 (NO 3 ) 2 ] · 6CH 3 CN ( 1 ), has been synthesized from the Schiff base ligand 1,3‐bis(salicylideneamino)‐2‐propanol and dysprosium nitrate. A single‐crystal X‐ray diffraction study reveals that the core of 1 consists of an edge‐t…
Additive is an effective factor in controlling crystallization of polymorph. l -Tryptophan, l -leucine, l -threonine, l -histidine, l -alanine, and l -valine, as additives during l -glutamic acid crystallization, were investigated for probing their effects on the polymorphic transformation. l -Tryptophan was then chos…
Abstract Mesh‐like fiber mats of polystyrene (PS) were deposited using DC‐biased AC‐electrospinning. Superhydrophobic surfaces with water contact angles greater than 150° and gas fraction values of up to 97% were obtained. Rheological study was conducted on these fiber surfaces and showed a decrease in shear stress wh…
Abstract A network of thermally responsive shape‐memory polymers (SMPs) could imbibe a quantity of solvent molecules to swell, and subsequently induces a chemical potential change in polymer. When an equilibrium is reached between the mechanical load and the chemical potential of polymer network and solvent, the SMP p…
Abstract The combination of different types of organo‐modified montmorillonite (MMT) with aluminum hydroxide (aluminum trihydrate—ATH), as a flame retardant system for polyethylene‐ethylene vinyl acetate (LDPE/EVA), blends were studied. Five different types of organically modified montmorillonite clays, each with diff…
Epoxy resin nanocomposites reinforced with three different ionic liquid functionalized carbon nanotubes (f-CNTs) were fabricated by an in situpolymerization method. The influence of the anions on the curing process was studied through differential scanning calorimetry (DSC) and normalized Fourier transform infrared (F…
We report a simple but efficient method to prepare metallic nanowire-graphene (MN-G) hybrid nanostructures at a low temperature and show its application to the fabrication of flexible field emission devices. In this method, a graphene layer was transferred onto an anodic alumina oxide template, and vertically aligned…
A strategy for construction of a solid-state electrogenerated chemiluminescence (ECL) sensor based on a self-assembled film of core/shell structural CdSe/ZnS quantum dots (QDs) is presented in this work for the first time. The surface coverage of CdSe/ZnS QDs is about 2.2 × 10 12 NPs/cm 2, which is on the level of a s…
Integrated all-diamond ultramicroelectrode arrays (UMEAs) were fabricated using standard photolithography processes. The array consisted of typically 45 ultramicroelectrodes with a diameter of 10 μm and with a center-to-center spacing of 60 μm. The quasi-reference and counter electrodes were made from conductive diamo…
The linear (χ (1) ) and second-order nonlinear (χ (2) ) optical properties of two anil crystals, [ N -(4-hydroxy)-salicylidene-amino-4-(methylbenzoate) and N -(3,5-di- tert -butylsalicylidene)-4-aminopyridine, denoted 4A and 4P, respectively], as well as the optical contrasts upon switching between their enol (E) and…
Theoretical and experimental methods of characterization have been employed to investigate a series of six push-pull molecules containing a 4,5-dicyanoimidazole acceptor (A) unit, a N,N-dimethylamino donor (D) group, and systematically enlarged π-conjugated linkers (π) with the view of assessing their first hyperpolar…
Pure, perfectly spherical cellulose nanoparticles with sizes of ≈80-260 nm can be prepared by dialysis starting from trimethylsilylcellulose (TMSC). The aqueous suspensions obtained are storable for several months. Subsequent covalent labeling of the cellulose nanoparticles with FITC has no influence on particle size,…
Abstract A set of linear polyurethanes containing isosorbide units were synthesized by polymerization in solution from HDI and MDI diisocyanates and 1,4‐butanediol (BD), isosorbide (Is) or diisosorbide diurethanes (Is 2 HDI and Is 2 MDI) as diols. The thermal transitions, thermal stability, and crystal structure of th…
