This paper describes the sensing application of water-dispersible dopamine dithiocarbamate decorated gold nanoparticles (DDTC-Au NPs) as sensors for the colorimetric detection of Cu 2+ ions in water samples. Dopamine dithiocarbamate (DDTC) molecules were successfully attached on the surfaces of Au NPs and were charact…
Articular cartilage is a unique tissue owing to its ability to withstand repetitive compressive stress throughout an individual's lifetime. However, its major limitation is the inability to heal even the most minor injuries. There still remains an inherent lack of strategies that stimulate hyaline-like articular carti…
A new type of fluoride glasses with high erbium-doping concentration (up to 6 mol. % Er(3+)) is investigated. The intensive 2.7 μm fluorescence is demonstrated with minimized concentration quenching. The intensity parameters and radiative properties are determined from the absorption spectrum based on the Judd-Ofelt t…
Adhesion layers, required to stabilize metallic nanostructures, dramatically deteriorate the performances of plasmonic sensors, by severely damping the plasmon modes. In this article, we show that these detrimental effects critically depend on the overlap of the electromagnetic near-field of the resonant plasmon mode…
In this paper, a new kind of hierarchical tube with a negative Poisson’s ratio (NPR) is proposed. The first level tube is constructed by rolling up an auxetic hexagonal honeycomb. Then, the second level tube is produced by substituting the arm of the auxetic sheet with the first level tube and rolling it up. The Nth (…
A neutral conjugated polymer poly-p-phenylene (PPP) derivative, poly(1,4-bis-(8-(4-phenylthiazole-2-thiol)-octyloxy)-benzene) (PPT), was prepared using a simple and economical method of oxidative polymerization reaction. This newly synthesized polymer PPT was characterized by means of Fourier transform infrared spectr…
Previous observations of methyl formate (HCOOCH 3 ) during the photo-oxidation of methanol (CH 3 OH) on TiO 2 catalysts suggested that photocatalysis on TiO 2 could be used to build up complex molecules from a single precursor. We have investigated the mechanism of HCOOCH 3 formation by irradiating a CH 3 OH-adsorbed…
The thermostats in molecular dynamics (MD) simulations of highly confined channel flow may have significant influences on the fidelity of transport phenomena. In this study, we exploit non-equilibrium MD simulations to generate Couette flows with different combinations of thermostat algorithms and strategies. We provi…
Precipitate size and number density are two key factors for tailoring the mechanical behavior of nanoscale precipitate-hardened alloys. However, during thermal aging, the precipitate size and number density change, leading to either poor strength or high strength but significantly reduced ductility. Here we demonstrat…
In-depth analysis of operando X-ray pair distribution function (PDF) data is combined with Li NMR spectroscopy to gain comprehensive insights into the electrochemical reaction mechanism of high-performance iron oxyfluoride electrodes. While the full discharge capacity could be recovered upon charge, implying reversibi…
A rapid and controllable route is developed for the synthesis of MnO nanoparticles that are encapsulated uniformly in three-dimensional (3D) mesoporous interconnected carbon networks (MnO-MICN) through an efficient microwave-polyol process, combined with a subsequent thermal treatment. The dependence of sodium citrate…
Graphene/reduced graphene oxide (rGO) modification has been demonstrated to be an efficient route to improve the photocatalytic performance of various photocatalysts by promoting the effective separation of photogenerated electrons and holes. It is highly required to develop facile and environmental-friendly methods f…
Self-assembly of Au nanoparticles (NPs) coated with positively charged cetyltrimethylammonium ions (CTA(+)) and negatively charged citrate ions in aqueous liquid cell was investigated by in situ transmission electron microscopy (TEM). Under electron illumination in TEM, the hydrated electrons will reduce the overall p…
Covering a broad range of polymer science topics, Handbook of Polymer Synthesis, Characterization, and Processing provides polymer industry professionals and researchers in polymer science and technology with a single, comprehensive handbook summarizing all aspects involved in the polymer production chain. The handboo…
5-(Hydroxymethyl)furfural (HMF) and levulinic acid production from glucose in a cascade of reactions using a Lewis acid (CrCl3) catalyst together with a Brønsted acid (HCl) catalyst in aqueous media is investigated. It is shown that CrCl3 is an active Lewis acid catalyst in glucose isomerization to fructose, and the c…

A martensitic phase-transition in pulsed-laser deposited manganese stabilized zirconia (MnSZ) thin films is demonstrated. For atomic Mn contents of MnZrO thin films between 0.1 and 0.15, the martensitic transformation of the tetragonal high temperature phase to the monoclinic low temperature phase is revealed. (001)-o…
Magnetostrictive materials exhibit a resonant frequency under an alternating magnetic field. Amorphous iron-boron film is well known as a magnetostrictive material. In order to obtain an amorphous phase of FeB thin film by electrochemical deposition, solution deposition parameters - such as current density, solution c…
A classical molecular mechanics force field, able to simulate coordination polymers (CP) based on ruthenium carboxylates (Ru2 (O2CReq )4 Lax) (eq = equatorial group containing aliphatic chains, Lax = axial ligand), has been developed. New parameters extracted from experimental data and quantum calculations on short al…
A novel fully rigid, rod-shaped oligo(p-benzamide) (OPBA-6) molecule was designed and synthesized, which can be recrystallized into a three-dimensional (3D) multilayer material via an antiparallel molecular packing model. Intermolecular hydrogen bonding and π-π interaction are brought to ensure a strong intralayer int…
