Herein, we report on the intriguing electrical transport properties of compressed AlAs. The relative permittivity and the resistances of both the grain and bulk boundaries vary abnormally at ∼10.9 GPa, accompanied by the cubic-hexagonal structural transition of AlAs. With further compression, the boundary effect becom…
A simple, coarse-grained model of chiral, helical filaments is used to study the polymorphism of fibrous aggregates. Three generic morphologies of the aggregates are observed: ribbons, in which the filaments are joined side-by-side, twisted, helicoidal fibrils, in which filaments entwine along each other and tubular f…
It is important to understand the interface and interaction between graphene layers and SiC surfaces as well as the interaction of key intermediate Si and C atoms with these surfaces and interfaces in epitaxial graphene growth on SiC substrates.
Wurtzite Cu3ZnInSnS6 (CZITS) nanodisks were successfully synthesized according to rational design via a hot-injection method. Their suitable band gap and photoresponsive behavior indicate great potential application in solar cells. The structure of CZITS transforms to a tetragonal type after annealing, which is accomp…
Biodegradable polyurethane is an ideal candidate material to fabricate tissue engineered hypopharynx from its good mechanical properties and biodegradability. We thus synthesized a hydrophilic polyurethane via reactions among polyethylene glycol (PEG), e-caprolactone (e-CL) and hexamethylene diisocyanate (HDI), and th…
Porous NiO/sGNS composites with enhanced electrochemical performances were successfully fabricated using ammonium carbamate as a precipitating agent.
The longitudinal absorption wavelength of pre-synthesized gold nanorods is precisely tuned by introducing controlled amounts of sulfide additives, which allows a powerful second chance to adjust the absorption wavelength of gold nanorods.
In this paper described applicability of xenon gamma detector for identification and characterization of radioactive waste was researched. Standard calibration gamma ray sources were used to determine real physical and technical characteristics of xenon gamma spectrometer. Samples of radioactive waste were measured by…
An alternative for the reutilization of polystyrene waste containers consisting in creating a hybrid material made of SiO2 nanoparticles embedded in a matrix of recycled polystyrene (PSR) has been developed. Recycled polystyrene functionalized (PSRF) was used to influence the morphological and antifog properties by th…
A laser field is a potential control tool for operating ultrafast electronic devices due to a wide variety of options such as field strength, frequency, and polarization. To investigate these variables upon electron transport through a single-molecule device, we simulate a phenyl-acetylene macrocycle (PAM) within a li…
Nine 3D isomorphic bimetallic coordination polymers with different alkali metals (Na, K, and Rb) and halides (Cl, Br, and I) have demonstrated that the 4,5-dicyanoimidazole ligand is a good template in the assembly of bimetallic–organic networks. This provides an excellent template for the investigation of ion exchang…
We report the electronic properties of two-dimensional systems made of graphene nanoribbons, which are patterned with ad-atoms in two separated regions. Due to the extra electronic confinement induced by the presence of impurities, we find resonant levels, quasi-bound and impurity-induced localized states, which deter…
Nanoparticles with various sizes and molecular weights were produced via altering the amount of the monomer and DPE in the SFEP.
Two conjugated molecules were investigated as electron acceptors for OPVs and it was observed that their power conversion efficiency can reach 1.84% after blending with P3HT.
Two-proton or two-electron transfer of the title biphenolic dication proceeds nearly simultaneously to induce 2,6'/2',6- or 6,6'-bond formation to give dioxapyrene or dihydrophenanthrene derivatives, respectively, with vivid changes in color (halochromism and electrochromism).
A theoretical model for the prediction of practical adhesion of dynamically- and structurally heterogeneous polymeric networks on solid surfaces.
Lindqvist-, Keggin-, and Anderson-type polyoxometalate organic–inorganic hybrids were designed to investigate their charge transfer character and screen them as high performance p-type sensitizers.
Our recent results in the field of engineering and application of highly oriented conjugates of single-domain antibodies and fluorescent quantum dots are summarized. These novel conjugates proved to be excellent nanoprobes for immunolabeling of tumor-associated biomarkers on cells and tissue specimens detectable by me…
Nanocrystalline ZnO performs remarkably well as photoanode when it is sensitized with fully organic D–π–A dyes.
The solid state chemistry of mixed-metal oxides containing rare earths (4f elements) and 4d or 5d transition elements has attracted a great deal of interest, because these materials adopt a diverse range of structures and show a wide range of electronic properties due to 4f and 4d (or 5d) electrons. We have focused ou…
