We show how orbital-free molecular dynamics can be regarded as the limit of quantum molecular dynamics at high temperature for the calculation of the equation of state of carbon. As a result, we construct an approach that allows to reproduce the quantum molecular dynamics equation of state of carbon at high temperatur…
The redistribution of ions in light-emitting electrochemical cells (LECs) plays a key role in their functionality. The direct quantitative mapping of ion density distributions in operating realistic sandwich-type devices, however, has not been experimentally achieved. Here we operate high-performing [Super Yellow/trim…
The elusive γ phase of trimesic acid (TMA, 1,3,5-benzenetricarboxylic acid) has been prepared by recrystallization of commercial α-TMA in acetic acid. This process yields a modified γ-TMA phase that contains guest acetic acid solvent molecules with an approximate stoichiometry of γ-TMA·1HAc. According to 1 H NMR and c…
Molybdenum (Mo) is the most commonly used material as back contact in thin-film solar cells. Adhesion of Mo film to soda-lime glass (SLG) substrate is crucial to the performance of solar cells. In this study, an optimized bilayer structure made of a thin layer of Mo on an ultra-thin chromium (Cr) adhesion layer is use…
The fatigue properties of EP/A356 aluminium matrix syntactic foams were measured. Four different type of syntactic foam were produced in order to determine the relation between the density and the fatigue properties. The density range was set to be between 0.7 – 1.1 g/cm 3 . The measured values indicated that, both th…
Abstract The nanohybrids of noble metal (M=Ag, Au, Pd, Pt, and Ru) nanoparticle‐decorated rhenium disulfide nanosheets (ReS2 NSs) were demonstrated as excellent catalysts towards the reduction of aromatic nitro compounds. The M/ReS2 nanohybrids were synthesized by facile hydrothermal method and characterization result…
In this paper have been proposed theoretical bases for formation one-dimensional contours of the first order smoothness, passing through k in advance given points, including requirements to the contour in general, and the contour’s arcs in particular, as well as representations for tangents in extreme and intermediate…
Abstract We report the findings of a study into the suitability of copper (I) thiocyanate (CuSCN) as a hole-transport layer in inverted photovoltaic (PV) devices based on the black gamma phase (B-γ) of CsSnI3 perovskite. Remarkably, when B-γ-CsSnI3 perovskite is deposited from a dimethylformamide solution onto a 180–1…
Covalent organic networks derived from surface‐mediated self‐assembly of 1,3,5‐tris(4‐bromophenyl)benzene into two‐dimensional networks on Au(111) have been studied by scanning tunneling microscopy (STM) and by X‐ray spectroscopic methods. High resolution soft X‐ray photoemission spectroscopy (SXPS) using synchrotron…
Lactate detection with electrochemical biosensors is a fundamental part of the sensing and biosensing research field. Together with glucose detection, this topic attracted scientist attention since the 60s. Lactate is a metabolite involved in many processes among several fields of application, from food degradation, t…
Chemical speciation of the soil solution is an important tool to identify Al species related to phytotoxicity. In some Brazilian acid soils, the Al extractable by the KCl 1.0 mol L -1 solution (Al-KCl) exceeds 10 cmol c kg -1 and even then, in some situations, it does not cause toxicity to the plants. This study aimed…
Abstract Oxime, whose dynamic nature was reported to be switchable between ON/OFF by tuning the acidity, is employed in a novel type of dynamic covalent approach that is amenable to use in water for self‐assembly of purely organic molecules with complex topology. In strongly acidic conditions, the dynamic nature of ox…
A novel metal–organic compound [Fe (ox)(phen)]n (phen = 1,10‐Phennannthroline, ox = oxalate acid) has been hydrothermally synthesized and structurally characterized by X‐ray single‐crystal diffraction, X‐ray diffraction, IR, UV–vis diffuse reflectance spectroscopy and X‐ray photoelectron spectroscopy. The compound cry…
It is vital that cellular- and tissue-based products (CTPs) used for wound treatment do not provoke autoimmunity. In this study, the immunogenic response to extracts of 2 CTPs of piscine and porcine origin was assessed in the collagen-induced arthritis model. Male DBA/1J mice were divided into 4 groups, each composed…
Abstract Molybdenum disulfide has drawn persistent interest as a promising nonprecious electrocatalyst alternative to Pt for the hydrogen evolution reaction (HER). However, the MoS2 catalytic efficiency is still lower than the Pt‐based catalysts owing to insufficient active sites with more inert basal planes. Herein,…
Abstract In order to improve the performance of localized surface plasmon resonance (LSPR) sensors, lattice plasmons of plasmonic nanoparticle (NP) arrays are often used. The lattice plasmon sensors based on coupling between LSPR of each NP and diffraction of the NP array generally have a higher ability to detect loca…
S/cm (30 °C, 30% relative humidity), as determined from dielectric relaxation spectroscopy, despite their highly crosslinked nature. Temperature-dependent conductivities demonstrate a dependence on polymer glass transition, with free-ion concentrations impacted by various ions' Lewis acidity/basicity and ion mobilitie…
Gas phase photoelectron spectroscopy (Rydberg Fingerprint Spectroscopy), TDDFT calculations and low temperature STM studies are combined to provide detailed information on the properties of the diffuse, low-lying Rydberg-like SAMO states of isolated Li@C60 endohedral fullerenes. The presence of the encapsulated Li is…
This article describes the synthesis of anionic polymer brushes and their mineralization with calcium phosphate. The brushes are based on poly(3-sulfopropyl methacrylate potassium salt) providing a highly charged polymer brush surface. Homogeneous brushes with reproducible thicknesses are obtained via surface-initiate…
This study explored the influence of different emulsification layers as mono- and bilayers on lipid digestion by using in vitro and in vivo digestion methods. The monolayer emulsion of rapeseed oil contained whey proteins and the bilayer emulsion, whey proteins and carboxymethyl cellulose. The in vitro digestion using…
