Sheaf-like, hyperbranched Zn2GeO4 nanoarchitectures were successfully synthesized in a binary ethylenediamine (En)/water solvent system using a solvothermal route. These structures may be assigned to the splitting crystal growth mechanism, resembling some minerals observed in nature. Addition of increasing amounts of…
A rich source: Calculated reaction and activation energies for elementary coupling reactions occurring on metal surfaces can be found by using a web application. This tool provides access to data for reactions of molecules with up to three C, N, or O atoms on a number of different transition-metal surfaces. The underl…
Graphitic thin films embedded with highly dispersed titanium dioxide (TiO(2)) nanoparticles were incorporated for the first time into the conventional dye-sensitized solar cells (DSSCs), resulting in a remarkably improved cell efficiency due to its superior electron conductivity. Massively ordered arrays of TiO(2) dot…
An amide-inserted metal-organic framework (NJU-Bai3) presents high storage and high selectivity toward CO(2) and combines these two interesting characters which strongly support our expectation that amide groups can significantly enhance the CO(2) binding ability and selectivity of MOFs.
Alginates comprise a rather broad family of polysaccharides found in brown seaweeds (Laminaria sp., Macrocystis sp., Lessonia sp. and others), from which they are produced industrially. The annual production is estimated to approximately 38.000 tons worldwide.1 In addition, a variety of different al...
A novel heterostructure consists of a metal Cd core and a ZnO–CdS heterostructural shell, where ZnO nanoparticles are embedded in a CdS shell. Photocatalytic hydrogen evolution is greatly improved due to the metal Cd core, which provides a charge-carrier transport channel for enhancing the recombination of photoexcite…
Herein we demonstrate the protocol of a biocatalytic precipitation (BCP)-based sandwich photoelectrochemical (PEC) horseradish peroxidase (HRP)-linked immunoassay on the basis of their synergy effect for the ultrasensitive detection of mouse IgG (antigen, Ag) as a model protein. The hybrid film consisting of oppositel…
The blending of two semiconducting polymers with offset energy levels enables efficient charge generation in thin-film ‘all-polymer’ solar cells. A key requirement for efficient charge separation and collection is the formation of interconnected phase-separated domains structured on the sub-20 nm length-scale. This re…
Density functional theory (DFT) calculations and Kinetic Monte Carlo (KMC) simulations were employed to investigate the methanol synthesis reaction from CO 2 hydrogenation (CO 2 + 3H 2 → CH 3 OH + H 2 O) on metal-doped Cu(111) surfaces. Both the formate pathway and the reverse water-gas shift (RWGS) reaction followed…
Tailoring nanoarchitecture of materials offers unprecedented opportunities in utilization of their functional properties. Nanostructures of vanadium oxide, synthesized by electrochemical deposition, are studied as a cathode material for rechargeable Na-ion batteries. Ex situ and in situ synchrotron characterizations r…
A photoanode based on ZnO nanotetrapods, which feature good vectorial electron transport and network forming ability, has been developed for efficient photoelectrochemical water splitting. Two strategies have been validated in significantly enhancing light harvesting. The first was demonstrated through a newly develop…
Multicompartment micelles are an intriguing class of self-assembled aggregates with subdivided solvophobic cores. They have been subject to extensive research in part due to their unique morphological and sequestration properties as a result of multiple distinct chemical environments being in close proximity within on…
Abstract Research on the luminescent solar concentrator (LSC) over the past thirty‐odd years is reviewed. The LSC is a simple device at its heart, employing a polymeric or glass waveguide and luminescent molecules to generate electricity from sunlight when attached to a photovoltaic cell. The LSC has the potential to…
Synthetic and characterization of the Mg 2 Al 3 formation by mechanical alloying have been carried out using a high energy ball milling process. Mechanical alloying is a technique of solid state reactions among two or more metals to form a new alloy through the deformation properties of the metals. The Mg 2 Al 3 alloy…
In the last years large attention was devoted to the synthesis and characterization of SBA-16 material focusing the interest on the formation mechanisms of copolymer micelles which drive the organization of the final siliceous mesostructure. However, there are relatively few reports on the block copolymer-silica self-…
Anomalous dispersion at the Si K absorption edge has been used to control the reflection from the interface between a film and an Si substrate, which otherwise complicates the nanostructure analysis of such a film, particularly for the soft-matter case, in grazing-incidence small-angle scattering. Such a reflectionles…
A systematic density functional theoretical study of the single-walled LiF nanotubes (NTs) in armchair ( n, n ) and zigzag ( n,0) (2 < n < 11) configurations is presented. Full geometry and spin optimizations with unrestricted symmetry have been performed. Both zigzag and armchair LiF NTs can exist stably because of t…
We use open-ended chains of oscillators, like those introduced by Fermi, Pasta, and Ulam, to mimic thermomechanical properties of crystalline solids, such as thermal expansion and the change of elasticity and quality factors with temperature. We employ molecular dynamics and theoretical arguments, separately. Features…
Most real life bubble dynamics applications involve multiple bubbles, for example, in cavitation erosion prevention, ultrasonic baths, underwater warfare, and medical applications involving microbubble contrast agents. Most scientific dealings with bubble-bubble interaction focus on two similarly sized bubbles. In thi…
The electron emission properties of an array of ZnO nanowires were studied in the temperature range of 300-473 K. An almost doubling of the current density at 473 K under an electric field of 8 V/μm (j(T=473 K) = 190 μA/cm2, j(T=300 K) = 114 μA/cm2) was observed together with a reduction of the turn-on field from 552…
