The paper describes the successful preparation of onion micelles by sequential combination of self-assembly of amphiphilic polyelectrolytes (PEs) in aqueous media and electrostatic coassembly of core–shell micelles formed in the first step with the oppositely charged double-hydrophilic copolymer. Experimental study an…
Refractory metals and their carbides possess extraordinary chemical and temperature resilience and exceptional mechanical strength. Yet, they are notoriously difficult to employ in additive manufacturing, due to the high temperatures needed for processing. State of the art approaches to manufacture these materials gen…
We present results of a theoretical study of a prototypical weak ferromagnet ${\mathrm{ZrZn}}_{2}$. We use the density-functional theory $(\mathrm{DFT})+\mathrm{dynamical}$ mean-field theory (DMFT) method to study the electronic and local magnetic properties. The obtained $\mathrm{DFT}+\mathrm{DMFT}$ electronic self-e…
To explore the connection between the architecture of poly(ether carbonate)s and certain physicochemical phenomena, the distribution of the length of oligomeric ether sequences was analyzed. Comparing experimental data with the expected distribution calculated with Monte Carlo methods revealed an unexpected preference…
Dynamic mechanical analysis (DMA) was used to investigate the viscoelastic behaviour of four species of wood, Scots pine, Gmelina, Obeche and Alstonia. Three frequencies (0.1, 1.0 and 10 Hz) were used over a temperature range of −150°C to +150°C. All the wood species showed tan δ peaks corresponding with secondary rel…
Optoelectronic photoelectrodes based on capacitive charge-transfer offer an attractive route to develop safe and effective neuromodulators. Here, we demonstrate efficient optoelectronic photoelectrodes that are based on the incorporation of quantum dots (QDs) into poly(3-hexylthiophene-2,5-diyl) (P3HT) and [6,6]-Pheny…
The study was intended to find in vitro antioxidant, cytotoxicity and safety profile of Polystichum braunii roots extracts and chemically characterise it by GC–MS and FTIR spectroscopy. Acute and sub-chronic (90-day oral repeated dose at 150, 300 and 600 mg/kg) toxicity studies of P. braunii methanol extract (PBME) we…
The effect of the addition of CeO2 to alumina-based washcoat slurry formulation on the methane steam reforming (MSR) reaction was investigated. Five Al2O3-CeO2-based washcoat slurries, differing from each other in the Al2O3/CeO2 ratio (nominal ratio equal to ∞, 0.042, 0.087, 0.250, 0.667) were prepared, dried and calc…
Abstract Due to the poor mechanical properties of traditional simulation models of the organic light-emitting device (OLED) bending area, this article puts forward a finite element model of 3D bending simulation of the OLED bending area. During the model construction, it is necessary to determine the viscoelastic and…
This paper investigates the effect of fiber laser surface modification of AISI 316L austenitic stainless steel on corrosion behavior. In the experiments, the fiber laser with center wavelength of 1062 nm was employed with various laser parameters of beam velocity and laser frequency. The laser-treated has performed on…
The internal friction of Cu50Zr50 metallic glass nano-pillars was investigated by using molecular dynamics simulations. An unusual non-monotonic variation of internal friction is revealed against the size of the specimen, which differs significantly from that of the bulk metallic glass. Meanwhile, by analyzing the rea…
Abstract Dynamic crack propagation in pressurized pipelines is usually investigated by means of lab-scale specimens due to its economic feasibility and material saving. More recently, new generation of pipeline steels have incredibly shown a combined fracture toughness and plastic strength capabilities with even more…
Electrochemical CO production from CO2 electrolysis has been considered the most economically viable approach among various candidate products. AuCu bimetallic alloys are currently receiving attention for their potential to tailor catalytic activity. Here, we synthesized a dilute AuCu alloy nanostructure with an AuCu…
The precise characterisation of the ground state absorption cross section around 800 nm for Nd:YAG from room temperature to liquid nitrogen temperature is presented. These results enabled the measurement of the energy transfer upconversion macroparameter over the same temperature range for 0.3at.%- and 0.6at.%-doped s…
Self-powered photodetectors have demonstrated potential for developing future wireless and implantable devices. Herein, we present a self-powered UV photodetector with an ultrahigh photoresponse based on vertically oriented and high crystalline quality n -type GaN nanorod arrays: poly(methyl methacrylate)/p-Si heteroj…
Abstract In offshore structures, pipelines and piping, there are various configurations where welds are often in close proximity to each other. TKY joints in offshore structures, welds of nozzles, tees, elbows and circumferential welds of piping in compact layouts are a few examples. Depending on their application, di…
Abstract Stimuli-responsive nanoparticles based on a reactive block copolymers (BCPs) of poly(ethylene glycol)-b-poly(2-vinyl-4,4-dimethylazlactone) (PEG-b-PVDMA) have been fabricated for loading and controlled release of molecular cargoes. Microphase segregation of PEG-b-PVDMA BCPs enables the construction of well-…
The effects of microstructural features on torsional ductility of cold drawn and annealed hyper-eutectoid steel wires were investigated. The patented wire rods were successively dry drawn to ε = 0.79 (54.7%) ~ 2.38 (90.7%). To examine the effects of hot-dip galvanizing conditions on torsional ductility, steel wires wi…

A strategy of efficient random lasing with resonant feedback based on a microemulsion comprising of BPLC, laser dye…
The AISI316 austenitic stainless steel die was prepared and nitrided at 673 K for 14.4 ks. Through this low temperature plasma nitriding, the AISI316 die was homogeneously hardened up to 1400 HV within its surface layer of 50 μm. This nitrided AISI316 die was utilized to print the tailored micropattern with nanotextur…
