Abstract The lowest energy structures for all of the eight‐vertex [M]CB6H7 {[M] = CpFe, CpRu. Co(CO)2, Rh(CO)2, (Me3P)2Fe(H), (Me3P)2Ru(H)}, [M]C2B5H7 {[M] = CpMn, CpRe, Cr(CO)3, Mo(CO)3}, and [M]2C2B4H6 ([M] = CpFe, CpRu) systems having 16 skeletal electrons were found by density functional theory to be capped pentag…
For many excellent graphene derivatives, tailoring the material properties is crucial to get a broader application. In the present work, a series of fluorinated graphene oxide (FGO) with various oxidation degree were synthesized using a modified Hummers method at different reaction temperatures. The structure and prop…
This study investigated the application of pressure on the superconducting properties of a thallium-based cuprate, namely Tl2Ba2Ca2Cu3O9-δ (Tl-2223). The superconducting transition temperature (Tc) and the critical current density (Jc) were studied by applying ~1 GPa of pressure. This hydrostatic pressure was applied…
The study presented in this paper is part of the technological surveillance performed at the Electricité De France (EDF) Research and Development (R&D) Center, in the Pericles department, and investigates the feasibility of modeling in-vessel melt retention (IVMR) phenomena for small modular reactors (SMR) with the mo…
Stimuli-responsive materials are attracting extensive interest as they offer the opportunity to transform external inputs such as light into a functionality by control at the molecular level. As a result, a large number of molecular building units have been developed that enable switching between two or more states. S…
The intrinsic sampling method (ISM) is a powerful tool that allows the exploration of interfacial properties from molecular simulations by fitting a function that represents the local boundary between two phases. However, owing to the non-physical nature of an "intrinsic" surface, there remains an ambiguity surroundin…
The qualitative behavior of charged particles in a vacuum is given by Earnshaw's theorem, which states that there is no steady configuration of charged particles in a vacuum that is asymptotically stable to perturbations. In a viscous fluid, examples of stationary configurations of sedimenting uncharged particles are…
Aim.The study was conducted for the characteristics of the morphoimmunohistochemical status of the implant from polylactic acid (PLA) located in the dermis. Materials and methods.The study was performed on rats (30 individuals) with subdermal administration of the drug in a volume of 0,05 ml. The results were evaluate…
Field and laboratory gamma measurements were performed for surface, adit, and core samples from Gabal Abu Dabbab albite granite Ta-Nb-Sn mining area, which is located some 50 km northwest of Marsa Alam city within the central Nubian Shield of Egypt. The field measurements were taken by portable RS-230 γ-ray spectrom…
Clays during lithogenesis change the composition, structure and properties, including physicochemical. The result of the thermal analysis was thermograms, on which four peaks of loss of bound water mass were established. These peaks in the author's interpretation are presented as different types of bound water in clay…
Abstract We demonstrate here that under a mild condition (aqueous solution, pH 7, 50 °C, 6 MPa O 2 ) gold nanocrystals (AuNCs) can catalyze the oxidation of 1‐phenylethane‐1,2‐diol to 2‐hydroxy‐1‐phenylethan‐1‐one selectively. And the yield can reach 87% when 94% the reactant is converted. Through comparing with diffe…
Abstract In this paper, three new kinds of phosphonium-based room temperature ionic liquids (ILs) [Ph3PCH3][CH3(CH2)8COO] (MTPP-D), [Ph3PCH3][CH3(CH2)10COO] (MTPP-L), and [Ph3PCH3][CH3(CH2)12COO] (MTPP-M) were synthesized using triphenylphosphine, dimethyl carbonate and carboxylic acids as raw materials. The viscosity…
In this paper we describe an algorithmic method to imitate geometries of soft magnetic composites. We use microscope images to determine some of the most important geometric characteristics of the material and optimize the algorithm such that the measured and simulated characteristics are in agreem ent. We compute the…
Thorium can be introduced into the energy vector in combination with high-grade plutonium (HG-Pu). Excellent neutron economy of heavy-water moderator allows use of mixed ThO2/HG-PuO2 fuel in heavy-water reactors with high efficiency, leading to the exploitation of large world thorium reserves and extending the availab…
Four novel salicyloylhydrazone derivatives and their terbium(III) complexes were synthesized and characterized. The thermal analysis results showed that the terbium(III) complexes possessed good thermal stability. The fluorescence research results showed that the terbium(III) complex substituted by phenyl possessed th…
This work is dedicated to an experimental research of strength and resistance characteristics of axially loaded concrete filled steel tube elements of self-stressing concrete, including high-performance concrete. Labcrete specimens of circular section 112 mm in diameter and 1000 mm in length were used in experiments.…
Non‐functionalized and n‐alkyl‐functionalized siloxane‐silsesquioxane resins (S4SQ) were synthesized and characterized to confirm their structure and properties. Polypropylene (PP) composites with S4SQ resins as fillers were prepared by the melt blending. The influence of the kinds and amounts of fillers on the struct…
This paper reports a facile, economical and surfactant free synthesis of three-dimensional hierarchical ZnCo 2 O 4 microspheres with water as medium. The scanning electron microscopic images demonstrated the evolution of hierarchical structure from solid sphere. Moreover, three dimensional microcubes were grown on ACF…
Abstract The hydrogen‐release reaction of a complex transition metal hydride, LaMg2NiH7, composed of La3+, 2×Mg2+, [NiH4]4− and 3×H−, was studied by thermal analyses, powder X‐ray, and neutron diffraction and inelastic neutron scattering. Upon heating, LaMg2NiH7 released hydrogen at approximately 567 K and decomposed…
Biological samples are radiation-sensitive and require imaging under low-dose conditions to minimize damage. As a result, images contain a high level of noise and exhibit signal-to-noise ratios that are typically significantly smaller than 1. Averaging techniques, either implicit or explicit, are used to overcome the…
