Paradigmatic quantum spin liquid has been in the past closely linked to the high-temperature superconductivity. Here we focus on a layered 1T-${\mathrm{TaS}}_{2}$, which has recently emerged as a surprising candidate for a quantum spin liquid on a triangular lattice. Upon doping 1T-${\mathrm{TaS}}_{2}$ with Se, the $^…
All-dielectric nanostructures have attracted attention for highly efficient light manipulation. Higher Q-factor Fano resonance can be excited due to the rich phenomenology of optical modes supported by high-index dielectric materials with low intrinsic material loss, including both electric and magnetic multipolar Mie…
The crossover from a Berezinskii-Kosterlitz-Thouless (BKT) rough surface to a Kardar-Parisi-Zhang (KPZ) rough surface on a vicinal surface is studied using the Monte Carlo method in the non-equilibrium steady state in order to address discrepancies between theoretical results and experiments. The model used is a restr…
Rotaxane dendrimers with hyperbranched macromolecular interlocked structures and size modulation capacity demonstrate drug binding and release ability upon external stimuli. Mass spectrometry imaging (MSI) can offer the high-throughput screening of endogenous/exogenous compounds. Herein, we reported a novel method to…
Abstract The electrode‐passivating species, phenol, was electrochemically determined by using semicircular sweep voltammetry on a basal‐plane pyrolytic graphite (BPPG) electrode. The electrode fouling caused by the polymerization of phenol was prevented at low concentrations by introducing a second species, 4‐amino‐2,…
We report the atomic- and nanosecond-scale quantification of kinetics of a shock-driven phase transition in Zr metal. We uniquely make use of a multiple shock-and-release loading pathway to shock Zr into the $\ensuremath{\beta}$ phase and to create a quasisteady pressure and temperature state shortly after. Coupling s…
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…
