Abstract Eight different silicon‐containing (meth)acrylate monomers are synthesized by the substitution reaction of chlorosiloxanes with 2‐hydroxyethyl methacrylate or 2‐hydroxyethyl acrylate. Their molecular structures are confirmed by IR, 1H‐NMR, and 13C‐NMR spectroscopic analyses. The effects of silicon content on…
AlGaN/GaN quantum well (QW) heterostructures grown by metalorganic chemical vapor deposition on sapphire and on free-standing GaN substrates have been studied by temperature dependent time-resolved photoluminescence. A dominant contribution of the exciton radiative lifetime is observed in homoepitaxial samples even at…
Archaeon Aeropyrum pernix K1 is an obligate aerobic hyperthermophilic organism with C25,25-archeol membrane lipids with head groups containing inositol. Interactions of archaeosomes, liposomes prepared from lipids of A. pernix, with mammalian cells in vitro were studied. In vitro cytotoxicity was tested on five differ…
Dense ceramics in S r N d A l O 4 ‐ S r 2 T i O 4 system were synthesized by a solid‐state reaction method, and their microstructures and microwave dielectric characteristics were investigated. The K 2 N i F 4 ‐type solid solutions with general formula S r 1+ x N d 1‐ x A l 1‐ x T i x O 4 were obtained in the entire c…
The influence of temperature and relative humidity on the moisture content of paper honeycomb sandwich panels was studied, and the ideal three-dimensional diagram between the moisture content of paper honeycomb sandwich panels and the temperature and relative humidity was constructed by the GAB model. The evaluation e…
Metal-ligand coordination and hydrophobic interaction are two significant driving forces in the aggregation of mixtures of M(n+) surfactants and alkyldimethylamine oxide (CnDMAO) in aqueous solutions. The coordinated systems exhibit rich aggregation behavior. This study investigated the effect of M(n+) ions (Zn(2+), C…
Directly functionalized multiwalled carbon nanotubes (MWCNTs) with benzene‐1,3,5‐tricarboxylic acid (BTC) and 3,5‐diaminobenzoic acid (DAB) were successfully accomplished with less structural damage as confirmed by XPS and FT‐Raman results. Their dispersibility and thermal stability were achieved after the functionali…
Nanowires of tetracene dicarboxylic imide disulfide with an N-hexyl substituent (HexylTIDS) were successfully constructed in composite thin film containing poly(3-hexylthiophene) (P3HT). The nanowire structures were investigated by atomic force microscopy and scanning electron microscopy. The photoconductivity of the…
Abstract The intermetallic compound CeAgSb2 is an unusual example of a ferromagnetically ordered Kondo lattice system. Ferromagnetism sets in below the Curie temperature TC = 9.6 K at ambient pressure and zero fields. We have investigated the sensitivity of the ferromagnetic phase to hydrostatic pressure and a transve…
Miscible displacement column experiments were performed to investigate the mobility of Zn in two different soils, Windsor (mixed, mesic Typic Udipsamment) and Webster (fine-loamy, mixed, superactive, mesic Typic Endoaquoll). In the Webster soil, strong Zn retention was observed due to a higher percentage of clay, orga…
We present a transmission electron microscope (TEM) and x-ray diffraction (XRD) study of metalorganic vapor phase epitaxy grown GaN layers on m-sapphire with Al(Ga)N interlayers. The interlayers are demonstrated to be beneficial in reducing the stacking fault (SF) density by more than 2.5 orders of magnitude from >2 ×…
One of the major challenges in tissue engineering is to supply larger three-dimensional (3D) bioengineered tissue transplants with sufficient amounts of nutrients and oxygen and to allow metabolite removal. Consequently, artificial vascularization strategies of such transplants are desired. One strategy focuses on end…
Quenching mechanisms of coumarin derivative 6-bromo-3-[1-(4,5-dicarbomethoxy-1,2,3-triazoloacetyl)]coumarin (6BDTC) were carried out in different solvents using the steady-state method to understand the role of diffusion in the quenching mechanism. The solute was excited by UV radiation of wavelength 360 nm. Various q…
Fresh-cut nectarines are very perishable product, and thus have a short shelf-life. In this study, minimally processed nectarines (cv Big Top) were treated with chitosan (20 g/L), sodium alginate (20 g/L) and Chitoplant® (20g/L), sealed in polypropylene plastic bags, and stored at 4°C for 5 days. Effects of the coatin…
We propose that the polaron transport in organic semiconductors is remarkably tuned by the fluctuation of polarization energy. The tuning effect of energetic fluctuation not only causes a continuous transition from non-Arrhenius to Arrhenius temperature activated charge transport with increasing moderate disorder stre…
A perpendicular InGaN/GaN multiple-quantum- wells structure on ZnO substrate for blue light emitting diode (LED) was successfully fabricated by use of Metal-organic Chemical Vapor Deposition (MOCVD). During the growing process of GaN-based materials on ZnO substrates, the low-temperature-grown GaN buffer layer, insert…
Polymer multiple quantum dots were fabricated on glass substrates by molecular layer deposition. The quantum dot length was controlled by connecting three source molecules with monomolecular steps in designated sequences and was estimated from theoretical structures to be in the range 0.9–3.1 nm. With decreasing dot l…
Highly efficient and prolonged coarse-grained molecular dynamics simulations revealed a previously unknown pathway of phase transition of (poor-solvent) conjugated polymer solutions, evolving from a rarely explored entangled state into elastic microgels characterized by interconnected fibrous (or arm-like) materials w…
We report a facile self-assembly strategy for fabricating TiO2 microlens arrays by localized hydrolysis of TiCl4 precursor in water droplets. Microcontact printing was used to define hydrophilic areas on a substrate for space resolved hydrolytic reaction. The water droplets served as the templates, reactant, and micro…
The behavior under thermal conditions of the cocrystal formed by metformin and salicylic acid was studied by DSC, crystallography (single-crystal), and powder diffraction (WAXS). Metformin salicylate crystallizes in space group P 2 1 / c, with the salicylate anion showing a planar structure, stabilized by strong intra…
