The mixed ionic-electronic conducting (MIEC) materials that have been developed for catalytic membrane reactors are vulnerable to a reducing atmosphere, especially H-2. We reported on a MIEC oxide, Sr0.7Ba0.3Fe0.9Mo0.1O3...
In concentrated clear sol prepared from tetraethylorthosilicate, tetrapropylammonium hydroxide, and water suitable for crystallization of Silicalite-1 zeolite, the main part of the silica is present in nanoparticles. The...
Inorganic ions may direct the self-assembly of biomacromolecules into nanostructures which can further be used as a reactant and matrix for nanomaterials synthesis and assembly. Here we use bone mineral and filamentous b...
Through a careful analysis of the role of formaldehyde in the preparation of silver nanomaterials, a previously unnoticed function of the reagent has been discovered. Formaldehyde reacts with ammonium hydroxide to form a...
New amphiphilic block copolymers composed of thermally and chemically stable poly(arylene sulfone ether ketone) and sulfonated poly(styrene-co-acrylonitrile) were successfully synthesized through two-step polymerization,...
We present a simple one-pot crystallization method, inspired by biological conditions, for the synthesis of hydroxyapatite (Ca-5(PO4)(3)OH) nanocrystals. The reaction proceeds via NH3 vapor diffusion into a CaCl2-NaH2PO4...
Manganese oxide octahedral molecular sieves (OMS) are important materials in environmental chemistry, electrochemistry, and heterogeneous catalysis. Here, a rapid process to prepare cryptomelane-type octahedral molecular...
We demonstrate large, partly reversible height and volume changes of thin films of poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS) on the anode of interdigitating gold electrodes under ambient conditi...
We demonstrate the application of scanning transmission X-ray microscopy (STXM) to image the angular distribution of grains in organic semiconductor thin film devices on the example of pentacene field-effect transistors....
The corrosion resistance of organic monolayer-coated germanium (Ge) nanowires was tested by exposure to various harsh chemical treatments, including boiling water, concentrated sulfuric acid, and hydrogen peroxide. The G...
Titania nanoparticles are widely studied for photoconversion processes where combining high surface area, charge transport properties, and chemical stability is meaningful. To enhance the conversion efficiency, new compo...
Well-defined diblock copolymers comprising thermosensitive poly(N-isopropyl acrylamide) (PNIPAM) and poly(n-butylacrylate) (PBA) blocks were synthesized by macromolecular design by interchange of xanthates (MADIX)/revers...
The use of yttrium aluminosilicate (YAS) glasses as vectors for radiotherapy is critically affected by the glass durability in a physiological medium. To understand the relation between glass composition, structure, and ...
