The exciting functionalities of natural superhydrophilic and superhydrophobic surfaces served as inspiration for a variety of biomimetic designs. In particular, the combination of both extreme wetting states to micropatterns opens up interesting applications, as the example of the fog-collecting Namib Desert beetle sh…
The discovery of the striking aggregation-induced emission (AIE) phenomenon has opened a new avenue for smart light-emitting materials. Herein, a new AIE luminogen (AIEgen), 1,1,2,2-tetrakis(4-((E)-2-(pyridin-2-yl)vinyl)phenyl)ethene (TP2VPE), has been designed and synthesized by introducing the vinylpyridine motifs i…
Abstract In this paper, a novel freestanding core‐branch negative and positive electrode material through integrating trim aligned Fe 2 O 3 nanoneedle arrays (Fe 2 O 3 NNAs) is first proposed with typical mesoporous structures and NiCo 2 O 4 /Ni(OH) 2 hybrid nanosheet arrays (NiCo 2 O 4 /Ni(OH) 2 HNAs) on SiC nanowire…
Two-dimensional birnessite has attracted attention for electrochemical energy storage because of the presence of redox active Mn 4+ /Mn 3+ ions and spacious interlayer channels available for ions diffusion. However, current strategies are largely limited to enhancing the electrical conductivity of birnessite. One key…
Abstract Isolated single atomic site catalysts have attracted great interest due to their remarkable catalytic properties. Because of their high surface energy, single atoms are highly mobile and tend to form aggregate during synthetic and catalytic processes. Therefore, it is a significant challenge to fabricate isol…
In view of serious environmental concerns with traditional Pb-based piezoelectrics, the search for new Pb-free alternatives has intensified recently. A thorough investigation of structure-property relationships in Pb-free piezoelectrics is desired in order to design new material compositions with high electromechanica…
A cryogenic permanent-magnet undulator (CPMU) with a 15-mm period length is being constructed for the TPS. Field measurements of this undulator will be performed with a Hall probe at cryogenic temperatures, for which a field strength and temperature-dependent calibration system is necessary. This system consists of a…
Polymers that allow the adjustment of Shape-Memory properties by the variation of physical parameters during programming are advantageous compared with their counterparts requiring synthesis of new material. Here, we explored the influence of hydrolytic (physical) aging on the Shape-Memory properties of the polyetheru…
Electronic states in the upper part of the bandgap of reduced and/or hydrogenated n-type rutile TiO2 single crystals have been studied by means of thermal admittance and deep-level transient spectroscopy measurements. The studies were performed at sample temperatures between 28 and 300 K. The results reveal limited ch…
ABSTRACT Stable superhydrophobic surface based on low‐density polyethylene (LDPE)/ethylene–propylene–diene terpolymer (EPDM) thermoplastic vulcanizate (TPV) was successfully fabricated by using etched aluminum foil as template. The etched aluminum template consisted of micropores and step‐like textures, was obtained b…
ABSTRACT The hybrid of bamboo charcoal (BCC) and silica‐reinforced styrene‐butadiene rubber was prepared by a modified sol–gel method of hydrolyzing tetraethoxysilane over an acid catalyst. The fracture surface of the samples after tensile test was characterized by field emission‐scanning electron microscopy. The tens…
Abstract Glass fibre reinforced polymers (GFRPs) have been widely used as one of the main electrical insulating structures for superconducting magnets. A new type of GFRP insulation material using cyanate ester/epoxy resin as a matrix was developed in this study, and the samples were irradiated by Co-60 for 1 MGy and…
Abstract
An advanced thermal interface material comprised of dense and orderly arrays of 10‐µm high Cu nanosprings with tunable normal and shear compliance, lateral stability due to spring intertwining, and thermal resistance below 1 mm 2 KW −1 is presented. The Cu nanospring films possess the compliance of soft polymers but u…
The application of bioscouring in cotton knitted fabrics should be improved owing to being a time-consuming process. In order to accelerate the bioscouring rate and shorten the bioscouring process, a repeated padding method is used on cotton knitted fabrics. The effect of the repeated padding with pectinase was studie…
A 2-stage model validation strategy for the previously developed solid oxide fuel cell model using the data from custom-designed experiments is presented. The strategy is based on the identification of model structural and parametric errors. In the preliminary validation, the causes that can result in the voltage erro…
Abstract This paper presents the results of studies on the preparation of cellulosic membranes, from a solution in 1-ethyl-3- methylimidazolium acetate (EMIMAc), using the phase inversion method. Initially, the membranes were obtained by coagulation of the polymer film in water and primary alcohols (methanol, ethanol,…
Using lysozyme as a crystallization model, existing intermediate clusters and aggregates have been previously identified as fractal systems using light scattering techniques. However, this has not been confirmed with neutron or X-ray scattering directly. In this work, we attempt to deepen our knowledge of the role of…
Controlled growth of circular single-crystalline graphene domains has been achieved by atmospheric pressure chemical vapor deposition (APCVD) using solid copper as substrate, thereby demonstrating that the shape of the graphene grains can potentially be precisely tuned by optimizing growth parameters. Scanning electro…
We show that polycrystalline $\mathrm{GeS}{\mathrm{b}}_{2}\mathrm{T}{\mathrm{e}}_{4}$ in the fcc phase (f-GST), which is an insulator at low temperature at ambient pressure, becomes a superconductor at elevated pressures. Our study of the superconductor-insulator transition versus pressure at low temperatures reveals…
