The extraordinary properties of reconfigurable soft materials are used to drive the resonance properties of noble metal nanoparticles, using an approach that puts a bridge between soft matter and plasmonics. Gold nanoparticles have been dissolved in a cholesteric liquid crystal and then infiltrated in a micro-periodic…
Microstructure Evolution During Plasma Electrolytic Oxidation and Its Effects on the Electrochemical Properties of AZ91D Mg Alloy, Ryu, Hyun Sam, Mun, Seong-Jae, Lim, Tae Seop, Kim, Hong-Chan, Shin, Kwang-Seon, Hong, Seong-Hyeon
In order to investigate the brittle-striation formation mechanism of a low carbon steel JIS S10C fatigued in a hydrogen gas environment, fractographic observations of the visualized fracture phenomena during some processes of brittle-striation formation were conducted. The following results were obtained. A striation…
The local morphology of the interface electrolyte/anode of solid oxide fuel cells has a strong effect on the electrochemically active triple-phase boundary length. Therefore, the electrical performance is expected to be enhanced by nanostructuring this interface. This study focuses on the anode functional layer (AFL)…
Polyurethane (PU) closed cell foam samples with different densities were tested under loading and unloading compression tests at different temperatures and strain rates. Quasi-static compression tests were performed using the Lloyd LR5K Plus instrument at strain rates ranges from 0.033–0.267 s−1. Tests were conducted…
One of the key issues in the development of the modern duplex stainless steels was the introduction of nitrogen as an alloying element. This was made possible by e.g. the AOD process and has meant that the problems with earlier grades regarding weldability could be solved. The prime reason for the lower weldability, n…
A facile supramolecular approach to prepare surface functionalized silver nanoparticle conjugates has been established and their enhanced molecular recognition features have been explored to demonstrate the uptake and stimulus responsive release of a phototherapeutic porphyrin dye, the TMPyP.
A simple, versatile and reproducible method for the preparation of hybrid inorganic–organic magnetic nanocolloids based on phospholipids and preformed magnetic nanoparticles has been proposed. Superparamagnetic hydrophilic and hydrophobic iron oxide nanoparticles (SPION) of similar size are synthesized as a first step…
This communication demonstrates a straightforward continuous-flow method for efficient exohedral functionalisation of carbon nanotubes which affords soluble samples in a much shorter time over conventional batch processing.
The morphology-selective synthesis of well-aligned Cu2-xSe nanostructures including nanosheets, nanoribbons, and heterostructures on copper substrate has been achieved by a simple hydrothermal route; the micropatterned assembly of Cu2-xSe nanostructures has been realized using a copper grid to direct the growth on pre…
V1-x Ti x O2 films were prepared on glass substrates by excimer-laser-assisted metal organic deposition (ELAMOD) and thermal MOD processes. The VO2 phase was successfully formed in the range of x = 0–0.35 at 300 °C in air using the ELAMOD process. This is a big advantage in terms of fabrication process for glass or or…
By combining both triptycene and multifunctional phthalocyanine components within a polymer of intrinsic microporosity (PIM), a polymer network of apparent BET surface of 806 m2 g−1 was obtained that appears to possess a highly rigid structure as determined from the shape of its nitrogen adsorption isotherm, which is…
The ability of a biological system to drive the formation of a microstructure as complex and ordered as the molluscan shell is of immense interest to the fields of nanotechnology and biomedicine. Although recent studies have greatly expanded our knowledge of the genes involved in shell formation, the mechanism by whic…
A novel varistor-composite synthesis for the fabrication of high breakdown voltage ZnO varistors has been successfully developed. It involves coating ZnO nanoparticles with SiO2 through the hydrolysis of tetraethyl orthosilicate (TEOS) and the subsequent coating of additives on the core of the SiO2-coated ZnO particle…
We report on the synthesis and investigation of self-assembly properties of new benzylidenehydrazine based compounds, namely N-(2,3,4-tridodecyloxybenzylidene)-3,4,5-N′-trialkoxybenzoylhydrazines. They were confirmed to exhibit wide ranges of room temperature hexagonal columnar liquid crystalline phases (Colh) as evid…
We report the synthesis and characterization of a series of para-halo-phenoxy-boronsubphthalocyanines (BsubPcs). Across this series, a crystal polymorph of p-bromophenoxy-BsubPc (α-BrPhO-BsubPc) contains a clear and discernible π–Br interaction directing crystallization into a motif not previously seen for phenoxy-Bsu…
The influence of slow heating rates: 2, 5, 10 and 30?C/min (0.033, 0.083, 0.166 and 0.50℃/s) on the β phase decomposition of Ti-5Al-5Mo-5V-3Cr (Ti-5553) during continuous heating were characterized by differential scanning calorimetry (DSC) analysis, light microscopy, scanning electron microscopy, X-ray diffraction an…
We have documented the fabrication of manganese dioxide (MnO 2 ) thin‐film electrochemical capacitor (EC) prototypes with dual‐planar electrode configuration. These EC prototypes exhibited good capacitive behaviors in mild Na 2 SO 4 aqueous electrolyte. Enhanced capacitive behaviors of EC prototypes were observed upon…
Three edible coating formulations, namely methyl cellulose (MC)-glycerol, sodium carboxymethyl cellulose (Na-CMC) - glycerol and hydroxypropylmethyl cellulose (HPMC) - stearic acid-glycerol with three concentrations of main edible components, MC (2, 3.5 and 5% w/v), Na CMC (0.1, 0.8 and 1.5% w/v) and HPMC (2, 4 and 6%…
