Self-assembly of porphyrin molecules can be controlled kinetically to form structures with lengths extending from the nano- to the micrometer scale, through a programmed solvent-diffusion process in designed microflow spaces. Temporal solvent structures generated in the microflow were successfully transcribed into mol…
An important component in hybrid atomistic-continuum (HAC) modeling of liquids is the proper termination of the atomistic subdomain (ΩA). When the HAC model is based on the Schwarz domain decomposition method, the total number of particles in ΩA is conserved using specular boundaries in an overlap region, where inform…
Partial discharge (PD) diagnostics is one of the most widely used tool to assess the insulation condition of insulated power cables and which facilitates informed maintenance planning leading to the extension of the service life of such ageing assets. PD occurs with varying intensity due to circuit loading and weather…
The geometric structure of woven fabric affects the appearance and physical properties and can be used to predict the weavability of the fabric. An accurate description of the structure is beneficial to predict the characteristics and the appearance of the woven fabric. The purpose of the study is to build an accurate…
In this work, we performed density functional calculations to investigate the adsorption and diffusion of hydrogen on Ni‐loaded graphene and single layer graphene oxide (SLGO). We evaluated the feasibility of hydrogen spillover in the presence of Ni4 cluster and the role of oxygen‐containing groups. Our calculations i…
Abstract A silica–alumina (SiO2–Al2O3) surface possessing both In3+ cations and an amine base has been prepared. Surface‐functionalized SiO2–Al2O3 was characterized by solid‐state 29Si MAS, 13C CP/MAS, and 27Al 2D MQ/MAS NMR spectroscopy; X‐ray photoelectron spectroscopy; and elemental analysis. The bifunctional surfa…
OBJECTIVE: To identify the original plant of "Daibaijie", commonly used Dai herb. METHOD: The literature review, morphology and anatomy, pharmacognosy, molecular biology, chemistry were used to analysis. RESULT: Daibaijie's historical scientific name, Dregea sinensis Hemsl., was mistakenly given "Daibaijie" and D. sin…
The growth of SiOx nanowires (NWs) with intense white emission is reported. Due to carbon monoxide gas being used as a dopant precursor, carbon-doped under-stoichiometric silicon dioxide NWs are obtained. The doping of the NWs is studied by means of x-ray photoelectron spectroscopy, which allows to assess the presence…
In this work, we report the successful development of a cement-rubber reactive composite with reversible mechanical properties. Initially, the composite behaves like rubber containing inert filler, but when exposed to water, it increases in volume and reaches a stiffness that is intermediate between that of hydrogenat…
We report an unusual robust ferromagnetic order above room temperature upon amorphization of perovskite [YCrO3] in pulsed laser deposited thin films. This is contrary to the usual expected formation of a spin glass magnetic state in the resulting disordered structure. To understand the underlying physics of this pheno…
Nature's functional surfaces are typically hierarchical multiscale structures. There are several techniques for producing such artificial structures on polymers but their mass production is not straightforward. We present here a simple and versatile method for manufacturing hierarchical multiscale polymer surface patt…
We have studied a range of pseudo-ternaries derived from the parent compound PrMn2Ge2, substituting for each constituent element with a smaller one to contract the lattice. This enables us to observe the magneto-elastic transitions that occur as the Mn-Mn nearest neighbour distance is reduced and to assess the role of…
Successful commissioning in the 1954 of the World’s First nuclear power plant constructed at the Institute for Physics and Power Engineering (IPPE) in Obninsk signaled a turn from military programs to peaceful utilization of atomic energy. Up to the decommissioning of this plant, the AM reactor served as one of the ma…
We propose a scheme to determine the energy-band dispersion of quasicrystals that does not require any periodic approximation and directly provides the correct structure of the extended Brillouin zones. From the gap labelling viewpoint, this allows us to transpose the measurement of the integrated density of states wi…
A nondestructive method was developed for grafting and retrieving polymer brushes from single-walled carbon nanotubes (SWCNT)s based on mussel-inspired chemistry. Thermo-responsive polymer brushes were grafted on SWCNTs by coating the tubes with polydopamine as a reactive underlayer and sequential surface-initiated at…
A facile method for synthesizing crystalline lithiated amines by ball milling primary amines with LiH was developed. The lithiated amines exhibit an unprecedented endothermic dehydrogenation feature in the temperature range of 150-250 °C, which shows potential as a new type of hydrogen storage material. Structural ana…
Nanostructured silicon‐based materials are good candidates for thermoelectric (TE) devices due to their low thermal conductivity, customizable electrical conductivity, and reduced cost. Generally, nanostructured TE bulk materials are obtained through compaction and sintering at high temperature (>1000 °C) of silicon n…
Surface-enhanced Raman spectroscopy takes advantage of plasmonic substrates that sustain resonances at tunable frequencies with a reproducibly extraordinary field enhancement. Low-cost and large-scale fabrication of these substrates is further required. Here, we present stacked large-scale arrays of strongly coupled g…
Tuning the properties of palladium nanoparticles using different protecting ligand shells is an important step toward the application-orientated design of nanoparticles for nanoelectronics and catalysis. We present a density functional theoretical characterization of Pd 13 and Pd 55 metal cores protected by only thiol…
Long-chain branched poly(ether sulfone)s (PESs) were synthesized via self-polycondensation of AB2 macromonomers. The linear PES oligomers synthesized by self-polycondensation of 4-chloro-4′-(4-hydroxyphenyloxy)diphenyl sulfone were terminated with 4-(3,5-methoxyphenoxy)-4′-fluorodiphenyl sulfone to form AB2 macromonom…
