Perturbation theory for graphene-integrated waveguides
We present perturbation theory for analysis of generic third-order nonlinear processes in graphene-integrated photonic structures. The optical response of graphene is treated as the nonlinear boundary condition in Maxwell's...
Effective osmotic cohesion due to the solvent molecules in a delocalized adsorbed monolayer.
A molecular thermodynamic model is derived for an uncharged delocalized surfactant monolayer adsorbed at a liquid interface, taking explicit account for the solvent molecules present in the monolayer. The model is based on the...
The Secular Evolution of a Uniform Density Star Cluster Immersed in a Compressible Galactic Tidal Field
PB Ivanov, DNC Lin
Dec 01, 2020
Abstract Nuclear stellar clusters are common in the center of galaxies. We consider the possibility that their progenitors assumed to be globular clusters may have formed...
Magnetoelectric doubling and mixing of electric and magnetic field frequencies in a layered multiferroic heterostructure

Nonlinear magnetoelectric effects in a disk-like heterostructure composed of a layer of amorphous ferromagnet (FeBSiC) mechanically coupled to a layer of piezoelectric ceramics (lead zirconate titanate) were studied both...

Heat extraction from HTS tape stacks applied in a superconducting motor in different cooling conditions
Abstract: The heat is generated inside the stack of superconducting tapes mounted on the surface of the electrical machine rotor during its operation and magnetization. Cooling of such stack presents challenges because of the...
MANUFACTURING MULTI-MATRIX COMPOSITES:
The formation of porosity is a major challenge in any composite manufacturing process, particularly in the absence of vacuum assistance. Highly localised injection of polymer matrix into regions of interest in a dry preform is a...
Revising testing of composite precursors – A new framework for data capture in complex multi-material systems
Any composite manufacturing method requires an application of a carefully designed consolidation process to ensure the suppression of voids in the laminate, establish bonding in laminate layers and prevent dimensional or...
Platelet P-selectin triggers rapid surface exposure of tissue factor in monocytes
Abstract: Tissue factor (TF) plays a central role in haemostasis and thrombosis. Following vascular damage, vessel wall TF initiates the extrinsic coagulation cascade. TF can also be exposed by monocytes. Inflammatory or...
Influence of precursors on the induction period and transition regime of dimethyl ether conversion to hydrocarbons over ZSM-5 catalysts

ZSM-5 catalysts were subjected to step response cycles of dimethyl ether (DME) at 300 °C in a temporal analysis of product (TAP) reactor. Propylene is the major olefin and displays an S-shaped profile. A 44 min induction...

Nonlinear magnetoelectric effect in a layered ferromagnetic-piezoelectric heterostructure excited by transverse magnetic field

The nonlinear magnetoelectric effect in a heterostructure containing layers of amorphous ferromagnet FeBSiC and piezoelectric lead zirconate titanate ceramics has been investigated. The heterostructure was subjected to...

Zeolite minilith
Structured microchannel H-ZSM-5 catalysts containing up to 80 wt% zeolite (balance bentonite) were fabricated by unit operations of paste preparation, extrusion, drying and firing. The structured catalysts, called miniliths due...
A spherical cavity model for quadrupolar dielectrics.
The dielectric properties of a fluid composed of molecules possessing both dipole and quadrupole moments are studied based on a model of the Onsager type (molecule in the centre of a spherical cavity). The dielectric...
Metallic Glass Films with Nanostructured Periodic Density Fluctuations Supported on Si/SiO2 as an Efficient Hydrogen Sorber.
Nanostructured metallic glass films (NMGF) can exhibit surface and intrinsic effects that give rise to unique physical and chemical properties. Here, a facile synthesis and electrochemical, structural, and morphologic...
Translational autoregulation of BZW1 and BZW2 expression by modulating the stringency of start codon selection.
The efficiency of start codon selection during ribosomal scanning in eukaryotic translation initiation is influenced by the context or flanking nucleotides surrounding the AUG codon. The levels of eukaryotic translation...
Revising testing of composite precursors – A new framework for data capture in complex multi-material systems
Any composite manufacturing method requires an application of a carefully designed consolidation process to ensure the suppression of voids in the laminate, establish bonding in laminate layers and prevent dimensional or...
Extensive layer clouds in the global electric circuit
A fair weather electric field has been observed near the Earth’s surface for over two centuries. The field is sustained by charge generation in distant disturbed weather regions, through current flow in the Global Electric...
Resolution of Low-Energy States in Spin-Exchange Transition-Metal Clusters
Polynuclear transition-metal (PNTM) clusters owe their catalytic activity to numerous energetically low-lying spin states and stable oxidation states. The characterization of their electronic structure represents one of the...
