We report the optical and vibrational properties of nanocrystalline MoS 2 thin films, which are comprised of stripe-like partially edge-terminated vertically aligned (ETVA) nano-size crystals dispersed in ⟨001⟩ oriented regions, grown on large insulating substrates. From high-resolution transmission electron microscop…
Interconnected α-Co(OH)2 nanosheets with various proportions of substituted Zn were electrochemically deposited on nickel foam substrates. The architectures were used directly as electrodes for supercapacitors, which exhibited excellent pseudocapacitive performance. Compared with the pure α-Co(OH)2 nanosheet electrode…
The interaction of hydrogen with defects in ZnO nanoparticles under H2–Ar mixed gas was investigated by positron annihilation, Raman and photoluminescence spectroscopy. Two series of experiments were performed, including annealing the samples in pure Ar gas and H2–Ar mixed gas. The thermal stability of hydrogen-relate…
Research on oxidase mimics is challenging but important. In this article, mercury(II) ion enabled citrate-capped silver nanoparticles (Cit–AgNPs) exhibit catalytic activity toward the oxidation of typical chromogenic substrate 3,3′,5,5′-tetramethylbenzidine (TMB) by dissolved oxygen under mild conditions, suggesting a…
Reported herein is the growth of bifunctional random copolymer chains from silica particles through a "grafting from" approach and the use of these copolymer-bearing particles to fabricate superamphiphobic coatings. The silica particles had a diameter of 90 ± 7 nm and were prepared through a modified Stöber process be…
This paper presents an overview on the use of various classes of nanomaterials in lubricant formulations. The following classes of nanomaterials are considered: fullerenes, nanodiamonds, ultradispersed boric acid and polytetrafluoroethylene (PTFE). Current advances in using nanomaterials in engine oils, industrial lub…
Recently, a novel cathode material PrBa0.5Sr0.5Co1.5Fe0.5O5+δ (PBSCF) has been proposed as a solution to overcome the drawbacks of a conventional cathode for intermediate-temperature solid oxide fuel cells (IT-SOFCs). Here we report systematic procedures to optimize the sintering temperature and the composite for PBSC…
High porosity, high performance macroporous biobased epoxy resins are produced by curing foam templates produced by mechanical frothing of a highly viscous epoxy resin.
We have developed an ellipsometry method to measure the physical aging rate of polymer films that have been thermally quenched and aged in a free-standing state where the stress imparted to the films is well-defined by the thermal-expansion mismatch between film and rigid support. For free-standing polystyrene films s…
We report here a facile approach to assembling low generation poly(amidoamine) (PAMAM) dendrimer-stabilized gold nanoparticles (Au DSNPs) onto electrospun polymer nanofibrous mats for catalytic applications. In this study, Au DSNPs formed using amine-terminated generation 2 PAMAM dendrimers as stabilizers were assembl…
Wrapping dendrimer-like soft nanoparticles by cell membrane is an essential event in their endocytosis in drug and gene delivery, but this process remains poorly elucidated. Using computer simulations and theoretical analysis, we report the detailed dynamics of the process in which a lipid bilayer membrane fully wraps…
We report a novel strategy to produce stable colloidal gold nanoparticles (AuNPs) in alginate aqueous solution which can be done in one step and without any chemicals. The AuNPs were produced by applying a voltage across a pair of gold electrodes which were immersed in alginate aqueous solution. Since the generation o…
Upconversion materials have been employed as energy relay materials in dye sensitized solar cells (DSCs) to broaden the range of light absorption. However, the origin of the enhancements can be induced by both upconversion and size-dependent light scattering effects. To clarify the role of the upconversion material in…
The interaction of metal oxides with their ambient environment at elevated temperatures is of significant relevance for the functionality and operation of ceramic fuel cells, electrolyzers, and gas sensors. Proton conductivity in metal oxides is a subtle transport process which is based on formation of oxygen vacancie…
A series of meso-substituted boron-bipyrromethene (BODIPY) dyes are synthesized and their laser and photophysical properties systematically studied. Laser emission covering a wide visible spectral region (from blue to orange) is obtained by just changing the electron donor character of the heteroatom at position 8. Th…
The extensive use of plastics in agriculture has increased the need for development and implementation of polymer materials that can degrade in soils under natural conditions. The biodegradation behavior in soil of polyhydroxyalkanoate (PHA) composites with 10 wt% distiller's dried grains with solubles (DDGS) was char…
With the recent development in pulsed lasers with ultrashort pulse widths or wavelengths, spatially precise, low-damage processing by femtosecond or deep-UV laser ablation has shown promise for the production of protein single crystals suitable for X-ray crystallography. Femtosecond laser processing of supersaturated…
The reactivity of reduced single walled carbon nanotubes (SWCNTs) (carbon nanotubides), prepared under strict inert conditions in a glovebox with respect to the covalent functionalization with hexyl iodide and subsequent exposure to ambient conditions (air, moisture), was systematically investigated by Raman, absorpti…
The conversion of multilayer graphenes into sp(3)-bonded carbon films on metal surfaces (through hydrogenation or fluorination of the outer surface of the top graphene layer) is indicated through first-principles computations. The main driving force for this conversion is the hybridization between sp(3) orbitals and m…
