We discuss how electronic-structure calculations can be used to identify the dominant point defects that control the growth and dissolution of the oxide barrier layer formed if a metal comes into contact with a corrosive environment. Using the example of the Zn/ZnO/H(2)O interface we develop and apply a theoretical ap…
Fire resistant coatings, composed of nanosized carbon black (CB) and polyurethane acrylate (PUA), were synthesized through a facile and low-cost method to improve the fire safety and thermal stability of flexible polyurethane foam (FPU).
Supramolecular polymers for solar energy harvesting can be created by considering carefully the relationship between topology, assembly, and photophysics.
Using first-principles calculations, we have investigated the structural, electronic, dynamical and mechanical properties of a recently synthesized Pnnm-CN. Phonon dispersion and elastic constant calculations were carried out to demonstrate the dynamical and mechanical stabilities of the Pnnm structure of CN at ambien…
A novel poly( <italic>p</italic> -dioxanone) dynamic network was fabricated from metallosupramolecular interactions <italic>via</italic> an elaborate synthetic strategy which shows excellent shape-memory performance.
Star-shaped POSS-polylactide based polyurethanes with improved shape fixity ratios (above 99%) and shape recovery ratios (around 84%) are presented.
Fabrication of CdS nanorods encrusted with MFe <sub>2</sub> O <sub>4</sub> nanoparticles (M = Zn, Co and Ni) gives magneto-luminescence nanocomposites with magnetically separable and visible light driven photocatalytic properties.
Full understanding and easy construction of specific biosensing principles is necessary for disease diagnostics and therapeutics in the hope of creating new types of biosensors. Herein, we developed a new conceptual nanobiosensing platform by coupling nanometal surface energy transfer (NSET) and photo-induced electron…
De-/re-hydrogenation of Li <sub>2</sub> Mg(NH) <sub>2</sub> at a temperature as low as 105 °C and stable reversibility through up to 20 cycles are successfully achieved by the nanosize-induced effects by double-shelled hollow carbon spheres.
We describe the synthesis of hierarchical porous nitrogen-doped carbon nanoparticles with high specific surface area and specific capacitance for supercapacitors.
Mg(II)bisporphyrin has been used as an efficient host for the selective binding of guest ligands. In the presence of heterogeneous guest pairs, 2-aminopyrimidine/pyrazine and 2-aminopyrimidine/1,4-dioxane, 2-aminopyrimidine is bound selectively inside the bisporphyrin cavity whereas pyrazine/1,4-dioxane is bound outsi…
We report a novel promising semiconductor of Ag3CuS2 serving as absorber material in inorganic-organic solid-state solar cells for the first time, and the device (ITO/ZnO/Ag3CuS2/P3HT/Pt) exhibits a power conversion efficiency of 2.01%. This study opens up an available method to develop various ternary absorber materi…
The pore structure of TEMPO-mediated oxidized CNF hydrogels, chemically cross-linked with water-soluble diamines, is studied. A solute exclusion method and pulsed-field-gradient NMR are used to estimate the mesh size distribution in the gel network in its hydrated state. Dextran fractions with the nominal molecular we…
A small peptide-based gelator forms stable hydrogels in an aqueous mixture with a range of poly(ethylene glycol) PEGs, from the ethylene glycol monomer to PEG 20 000 with stronger gels forming in polymeric PEG. Spectroscopic studies on these systems reveal significant secondary structural changes when compared to gels…
The presence of K <sub>2</sub> CO <sub>3</sub> significantly increased the catalytic activity and stability of Au NPs supported on magnesium oxide-based supports.
Flame-retardant waterborne polyurethanes with a phosphorus-containing flame retardant diamine (AWPUs) were synthesized and characterized by the method of post-chain extension technology.
The crystal structure of 2,4-dinitroanisole (24DNAN) is known to have two polymorphic structures (Z′ = 2 and Z′ = 1, hereafter referred to as α-form and β-form, respectively) and the oxygen atoms of the nitro group(s) of both polymorphs have been found to be disordered over two positions at 298 K. In the thermal behav…
Colloidal mesoporous silica nanoparticles asymmetrically capped with non-porous phenylsilsesquioxane have been prepared by adding phenyltriethoxysilane to an aqueous dispersion of mesostructured silica-surfactant composite nanoparticles. The integration of colloidal stability, mesoporosity and the Janus structure is q…
