MnAs thin films present a phase coexistence of regularly arranged ferromagnetic (α) and paramagnetic (β) stripes below the Curie temperature when grown onto GaAs(100) substrates. In this letter, we report the observation of a magneto-structural phase transition induced by magnetic field on MnAs nanoribbons below the C…
Yarn traversing with counter rotating blades is a well-established method of traversing the yarn, employed on several commercial winding machines. This method is mainly suitable for shorter traverse strokes and does not have positive control on yarn during traversing (especially at traverse extremes) as compared to ot…
The physical properties of mercury films on partially hydrogenated imperfect graphene are studied by means of molecular dynamics at 300 K. Films prepared on the basis of three various types of the atomic interaction potential for mercury and other constant interaction potentials are considered. It is shown that the on…
Physicochemical and molecular properties of complexes formed by aminoglycoside antibiotics, including neomycin, gentamicin, kanamycin, and amikacin, in the form of bases and carboxyl- or sulfo-comprising copolymers of acrylamide or N-(2-hydroxypropyl)methacrylamide have been studied. The toxicity of complexes in vitro…
Microwave and power electronics based on GaN enables the performance of systems and their safe operating area to be driven to ‘extremes’. One of the major issues that then arises is thermal management. This includes heat transfer limitations across interfaces, however also the need of incorporating novel high thermal…
Threefold symmetric rigid-core molecules with an internally grafted poly(ethylene oxide) (PEO) chain were synthesized, and their self-assembled structures were characterized using differential scanning calorimetry, TEM, and 1D and 2D X-ray scatterings in the solid state. The tripod compounds based on short PEO chains…
Hydrogenated rosin/polyacrylate composite miniemulsions-based pressure sensitive adhesives were synthesized by in situ miniemulsion polymerization method. The effect of HR amount on the monomer conversion rate, particle size and its polydispersity, coagulum rate, Zeta potential, and stability of the composite miniemul…
A new acoustic absorbing/cushioning composite is fabricated by thermoplastic polyurethanes honeycomb structure – thermoplastic polyurethane honeycomb cushion and grid, and composite nonwoven in this study. Composite nonwoven is composed of different layers of polyester/polypropylene nonwoven and polyester nonwoven. Re…
This paper presents an electrical-thermal-reliability co-design technique for TSV-based 3D-ICs. Although TSV-based 3D-IC shows significant electrical performance improvement compared to traditional 2D circuit, researchers have reported strong electromigration (EM) in TSVs, which is induced by the thermal mechanical st…
Fe nanoparticles (∼10 nm), used to grow carbon nanotubes (CNTs), have an outstanding ability to catalyze the dehydrogenation of LiAlH4 . The CNTs help connect Fe and LiAlH4 and create microchannels among the composite, thus promoting the release of hydrogen. Inspired by these results, a supercritical-CO2 -fluid-assist…
Accurate determination of both fundamental and optical gap is necessary for designing molecules relevant for organic photovoltaics. Here, we study how range-separated density functionals reproduce frontier orbital energies, HOMO (highest occupied molecular orbital)–LUMO (lowest unoccupied molecular orbital) gaps, and…
Automobile beam steel with high strength is the development trend of the automotive industry. With the development of heavy-duty vehicles, low cost automobile beam steel both with high strength and high toughness need to be developed. V-N microalloying method combined with thermal mechanical controlled process has a s…
To study the influence of soft magnetic phase coating on magnetic properties of hard/soft phase nanocomposite materials, the coating of soft magnetic FeCo on hard magnetic SmCo5nanochips was performed via a sonochemical process. First, anisotropic hard magnetic SmCo5nanochips were prepared by surfactant-assisted high-…
The molecular dynamics of flax-reinforced ethylene–propylene–diene monomer (EPDM) composites, with increasing quantities of flax (EPDM 0 –EPDM 20 ), was investigated by dynamic mechanical analysis. Multifrequency experiments were also performed in order to distinguish between the relaxation and the kinetic events. Als…
Controlled/living radical homopolymerization of isobornyl acrylate and its copolymerization with styrene with reversible chain transfer via the addition-fragmentation mechanism in the presence of benzyl dithiobenzoate have been studied. It has been shown that the (co)polymerization proceeds through living chains, a re…
An integrated model based on finite-element method has been proposed to examine the mechanical and thermal responses of strips and work-rolls in tandem and reverse cold rolling operations. The model has been developed such that the influence of various process parameters, such as lubrication, rolling speed, frictional…
We present a multiscale model, based on molecular dynamics (MD) and kinetic Monte Carlo (kMC), to study the aggregation driven growth of colloidal particles. Coarse-grained molecular dynamics (CGMD) simulations are employed to detect key agglomeration events and calculate the corresponding rate constants. The kMC simu…
This review summarizes the experimental kinetic data on the polymerization of various monomers mediated by reversible addition-fragmentation chain-transfer agents of various classes and the results of model experiments illustrating the conditions under which the products of termination of radical intermediates may be…
The reaction of copper(II) perchlorate with the hydrochloride salt of 3,6,9,15-tetra-azabicyclo[9.3.1]penta-deca-1,11,13-triene (L1) in acetonitrile forms two macrocyclic complexes that can be characterized: [L1CuIICl][ClO4] (1) and [L1CuIICl]2[CuCl4] (2). The structural, electronic, and redox properties of these comp…
In this paper, we present the effect of ferrite percentage content and electric current intensity passing through the electromagnet coil on magnetic properties (saturation induction, residual induction, and coercive field) of magnetic staple yarns. Also, we present a method for obtaining magnetic yarns by direct coati…
