The new Me 2 Si-bridged [1]ferrocenophane ([1]FCP) with one i Pr group in α position on a Cp ring was synthesized in an enantiopure ( S p - 4 ) and a racemic form ( rac - 4 ). The molecular structure of rac - 4 was determined by single-crystal X-ray analysis (tilt angle α = 20.15(14)°). Experimental and calculated mol…
The 2-D rotating magnetic field is demonstrated in electrical steel sheets, which are widely used in iron cores of motors, etc. In addition, the magnetic properties of a motor iron core are strongly affected by the compressive stress in the laminated direction induced by welding, bolt bundles, etc. In order to investi…
Abstract Harvesting the properties of nanosheets is not only crucial from a fundamental perspective, but also for the development of novel functional devices based on 2D nanosheets. Herein, we demonstrate the processing of organically modified TBAxH1−xCa2Nb3O10 nanosheets into photonic thin films and study their color…
New advanced numerical computer model enabling accurate simulation of fragmentation parameters of large Length over Diameter (L/D) explosively driven metal shells has been developed and validated. The newly developed large L/D multi-region model links three-dimensional axisymmetric high strain high strain-rate hydroco…
The directed self-assembly (DSA) of block copolymers (BCPs) is a potential solution for patterning critical features for integrated circuits at future technology nodes. For this process to be implemented, there needs to be a better understanding of how the template guides the assembly and induces subsurface changes in…
Abstract We studied the dependence between properties and synthesis method for PEGylated ZnS nanoparticles. Thus, we proposed the PEGylation of ZnS nanopowder, in non-aqueous medium, by a facile one-pot synthesis in very mild conditions, as an alternative for the chemical precipitation of PEGylated ZnS in an aqueous s…
This work investigates the high-pressure structure of freestanding superconducting $({T}_{c}=4.3$ K) boron-doped diamond (BDD) and how it affects the electronic and vibrational properties using Raman spectroscopy and x-ray diffraction in the 0--30 GPa range. High-pressure Raman scattering experiments revealed an abrup…
The charge densities, band structure, density of states, dielectric functions of Si-doped [Formula: see text]-Ga2O3 have been investigated based on the density functional theory (DFT) within the hybrid functional HSE06. The heavy doping makes conduction band split out more bands and further influences the band structu…
Abstract BACKGROUND Several layered double hydroxides (with Mg:Al ratio varying from 2:1 to 4:1) were prepared by a co‐precipitation method at constant pH value. The activity of laboratory prepared samples was compared with that of industrially prepared layered double hydroxides with the same Mg/Al ratio in aldol cond…
Various covalent decorations and structural transformations of a series of R–C(CH 2 OH) 3 triol ligands on Co II /Co III -centered Anderson–Evans polyoxomolybdates were studied in aqueous and/or organic solution. Single-crystal X-ray structural analysis demonstrated that four manners, including (1) double-sided χ/χ-is…
The thermoelectric properties (electrical conductivity, Seebeck coefficient, and power factor) of single layer transition metal dichalcogenides (MoS 2, MoSe 2, WS 2, and WSe 2 ) are investigated theoretically on the basis of ab initio quantum transport using the Landauer Büttiker formalism. The often used rigid band m…
The aim of this paper is to present research findings on the measurements of mechanical, morphological, and thermal properties of Roselle fiber-reinforced thermoplastic polyurethane composites. The Roselle fiber/thermoplastic polyurethane composites were prepared with fibers of different sizes such as 125 µm and lower…
Vibration of an embedded nanocomposite curved microbeam is investigated based on the modified couple stress theory and Timoshenko beam model. The microbeam is reinforced by single-walled carbon nanotubes (SWCNTs) considering agglomeration effects. The structure is subjected to axial magnetic field. Applying Hamilton's…
The effects of carbon fiber amount and length were studied on the flame retardant, thermal, and mechanical properties of the intumescent polypropylene composites. The flame retardant properties of the intumescent polypropylene-based composites were investigated using limiting oxygen index, vertical burning test (UL-94…
Solid-state luminophores operating in the near-infrared (NIR) region may have applications in sensing, communication, and medicine. We report environmentally protected solid-state NIR-emitting luminophores fabricated by embedding CdHgTe colloidal quantum dots (QDs) into a NaCl matrix, with remarkable photo- and therma…
Sewage sludge is repeatedly applied as fertilizer on farmland due to its high nutrient content. This may lead to a significant increase of silver nanomaterials (AgNM) in soil over years. Therefore, our aim was to investigate the ecotoxicity and fate of AgNM under environmentally relevant conditions in outdoor lysimete…
Understanding competitive adsorption relationship among various ambient gases is important in adsorbing-material development for capturing environmentally harmful gas. For example, environmental interfering factors (e.g., moisture) can affect the competitive gas-molecule adsorption that needs to be clarified. Due to a…
Nickel (Ni) metallization of polyimide (PI) was performed using a solution-based process including imide-ring opening reactions, the implanting of Ni ions, the reduction of catalytic Ni nanoparticles, and the electroless deposition of a Ni film. The start-up imide-ring opening reaction plays a crucial role in activati…
Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences has achieved the industrialization of the first generation catalysts for coal to ethylene glycol for the first time in 2009. However, there are still lots of aspects to be improved, such as high noble metal loading and toxic Cr in cat…
ABSTRACT Graphene nanosheets‐filled epoxy composites (GNS/Epoxy) were prepared at different filler loading levels from 0.25 to 3.00 wt %. A fast dispersion method as short as 5 min is employed to disperse GNS in epoxy matrix, which was enough for the homogeneous dispersion of GNS with the help of high ultrasonic frequ…
