We calculate the equilibrium shape of a droplet sitting on a tilted substrate with a "chemical step", that is, different lypophilicity at the two sides of the step. This problem can be generalized to that of a droplet experiencing a body force, pushing it from the lyophilic part to the lyophobic part of the substrate.…
This paper focuses on the surface properties of a-C:H:Cu composite coatings for medical devices and how the release of Cu2+ ions from such coatings can be controlled. The released Cu ions have the potential to act as a bactericidal agent and inhibit bacterial colonization. A PVD–PECVD hybrid process was used to deposi…
The ambipolar graphene field-effect transistors (GFETs) usually exhibit Λ-shaped resistance versus gate voltage characteristics (R-Vg curve) with the n- and p-type regions switching at the neutrality points of graphene. However, M-shaped R-Vg curves were frequently observed in our back-gated GFETs without intentional…
Tests are conducted to evaluate the effect of long‐term storage on the microstructure and microhardness of an oxygen‐free high conductivity (OFHC) copper after processing by high‐pressure torsion (HPT) for various numbers of revolutions at ambient temperature. Results are presented for samples subjected to storage at…
Abstract A series of Ni 4‐x Mn x Ti 1 O y mixed metal oxides (Ni 4‐x Mn x Ti 1 ‐LDO) catalysts originated from layered double hydroxides (LDHs) were fabricated and evaluated in the selective catalytic reduction of NO with NH 3 (NH 3 ‐SCR). To optimize the denitrification performance, the redox capability of catalysts…
The adsorption of humic substances on Ag nanoparticles (AgNPs) is of crucial environmental importance and determines the toxicity of these NPs and the structure of adsorbed organic matter. In this work, the adsorption of two standard soil and leonardite International Humic Substances Society humic acids was studied on…
The separator is an important component of the lithium‐ion batteries (LIBs). Considering the influence of temperature and hygroexpansion effect of cellulose materials, the mechanical properties of cellulose separators in air (dry), electrolyte immersion (wet), and elevated temperature (heated) environments are studied…
The porosity of a newly synthesized phosphorene antidot lattice (PAL) is promising for encapsulating the porphyrin molecule and thus shows a versatile route to fabricate porphyrin/PAL nanocomposites. We herein explored the photovoltaic performance of a tetraphenylporphyrin (TPP)/PAL composite system. Interestingly, TP…
Corrosion Protection for the Oil and Gas Industry: Pipelines, Subsea Equipment, and Structures summarizes the main causes of corrosion and requirements for materials protection, selection of corrosion-resistant materials and coating materials commonly used for corrosion protection, and the limitations to their use, ap…
High Resolution Image Download MS PowerPoint Slide An amphiphilic block copolymer (BCP) which contains both photoresponsive and thermoresponsive blocks was synthesized by the atom transfer radical polymerization approach. Meanwhile, a new core/shell type of the upconversion nanoparticle (UCNP) LiYF 4:Yb 3+ 0.25,Tm 3+…
Abstract Perylene diimide (PDI) derivatives hold great promise as stable, solution‐printable n‐type organic thermoelectric materials, but as of yet lack sufficient electrical conductivity to warrant further development. Hybrid PDI‐inorganic nanomaterials have the potential to leverage these physical advantages while s…
Abstract Galvanic reaction is a classic reaction and widely applied in nanoscience and nanotechnology. However, it is rarely employed in the synthesis of doped metal nanoclusters with size less than ≈2 nm and remains to be exploited in nanocluster (NC) community. Herein, it is reported the synthesis of chiral Ag 4 Pd…
ZnO-based nanomaterials have been proven to be of great use for several leading applications since the beginning of nanoscience due to the abundance of zinc element and the relatively easy conversion of its oxide to nanostructures. Nowadays, ZnO as nanoparticles, nanowires, nanofibers as well as plenty of other sophis…
Topological lightwave technologies are expected to be applied in a wide range of emerging optical fields such as q-plates, one of the most attractive devices in this research area, prepared by controlling the high-resolution alignment patterning of liquid crystals. Here, we present a simple and direct fabrication tech…
Sunflower stalks could be an alternative raw material for use in the particleboard industry since the requirements of P1 general purpose boards for use in dry conditions and P2 boards for interior fitment for use in dry conditions are easily satisfied. Acetylation of sunflower stalks is found to greatly improve the th…
Multifunctional materials have become the development trend of current material preparation.
