A BaO infiltrated La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) cathode shows remarkable tolerance and resistance towards chromium via the formation of BaCrO4 instead of SrCrO4 on the electrode surface, preventing the excess Sr deficiency at the A-site of LSCF perovskite and thus mitigating the Cr poisoning effect.
We study the correlation of wetting properties and corrosion rates on hydrophobized cast iron. Samples of different surface roughnesses (abraded by sandpaper) are studied without coating and with two types of hydrophobic coatings (stearic acid and a liquid repelling spray). The contact angles and contact angle hystere…
We demonstrate the impact of reducing agents for Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD) of WS2 from WF6 and H2S precursors. Nanocrystalline WS2 layers with a two-dimensional structure can be obtained at low deposition temperatures (300-450 °C) without using a template or anneal.
Nitrogen and sulfur atom co-doped carbon dots can be used as a photosensitizer for high-performance photoelectrical conversion devices.
The sensitivity of OECT-based epinephrine sensors has been dramatically improved by modifying carbon nanomaterials on the Pt gate electrodes.
High temperature solid oxide cells (SOCs) are attractive for storage and regeneration of renewable energy by operating reversibly in solid oxide electrolysis cell (SOEC) and solid oxide fuel cell (SOFC) modes. However, the stability of SOCs, particularly the deterioration of the performance of oxygen electrodes in the…
Incorporation of nanohydroxyapatite (nHAP) within a chitosan (CS)/silk fibroin (SF) nanofibrous membrane scaffold (NMS) may provide a favorable microenvironment that more closely mimics the natural bone tissue physiology and facilitates enhanced osteogensis of the implanted cell population. In this study, we prepared…
We investigated how the presence of one anion effects the overall ZnO growth in the presence of another anion.
We describe biodegradable bridged silsesquioxane (BS) composite nanomaterials with an unusually high organic content (ca. 50%) based on oxamide components mimicking amino acid biocleavable groups. Unlike most bulk BS materials, the design of sub-200 nm nearly monodisperse nanoparticles (NPs) was achieved. These enzyma…
Octahedral Fe 3 O 4 nanoparticles show a wide size range for high SAR values to be used as an excellent thermal seed for magnetic hyperthermia cancer treatment.
An efficiently designed microstructure leads to a record ZT value in p-type half-Heusler compounds.
A flexible all-solid-state supercapacitor was demonstrated with a flexible Ag nanoparticle current collector prepared by an R2R printed and laser annealing process.
We study the stochastic nature of primary nucleation and how it manifests itself in a crystallisation process at different scales and under different operating conditions. Such characteristics of nucleation are evident in many experiments where detection times of crystals are not identical, despite identical experimen…
A simple two-step seed-mediated method has been developed to synthesize chitosan supported Cu@Ag core–shell nanoparticles with superior bactericidal efficacy.
Pure chitosan membranes present insufficient mechanical properties and a high swelling ratio, which limits their application in biomedical field. In this study, silk microfibers were obtained by chemical hydrolysis, and a novel type of chitosan/silk microfiber (CS/mSF) blended membrane was reported and its multiple ph…
Gold-coated diarylethene crystals exhibited photoreversible bending upon alternating irradiation with ultraviolet (UV) and visible light. The bending behavior can be well explained by the extended bimetal model, which we propose here. Moreover, we have demonstrated that it can be used as an actual electrical circuit p…
The reinforcement of sulfur-vulcanized natural rubber using cellulose nanofibers (CNFs) was investigated.
MoS2@CuO heterogeneous structure nanoflowers were synthesized through a two-step hydrothermal method for the first time. The valence band offset (VBO) and conduction band offset (CBO) of the MoS2@CuO heterojunction, and the bases for the design of the heterogeneous structure were determined by X-ray photoemission spec…
A model of the catalytic reaction mechanisms for CO + O 2 and NO + CO for a two phase intergrowth and coexistence CuO–CeO 2 catalyst.
We developed a simple high-throughput colorimetric assay to detect glucose based on the glucose oxidase (GOx)-catalysed enlargement of gold nanoparticles (AuNPs). Compared with the currently available glucose kit method, the AuNP-based assay provides higher clinical sensitivity at lower cost, indicating its great pote…
