Electrophoresis of polyelectrolyte‐adsorbed soft particle with hydrophobic inner core

open access: yesELECTROPHORESIS, EarlyView.
Abstract This article deals with the electrophoresis of hydrophobic colloids absorbed by a layer of polymers with an exponential distribution of the polymer segments. The functional groups present in the polymer layer further follow the exponential distribution.

Time-dependent behaviour of an M/M/3 heterogeneous server queueing system with multiple vacations subject to system disaster

open access: yesMathematics in Applied Sciences and Engineering
This research paper investigates the dynamic behaviour of a heterogeneous three-server queuing model with multiple vacation. The model also accounts for the possibility that a disaster could occur during busy periods or on vacation, in which case the ...

All-optical mode conversion via spatially multimode four-wave mixing

open access: yesNew Journal of Physics, 2016
We experimentally demonstrate the conversion of a Gaussian beam to an approximate Bessel–Gauss mode by making use of a non-collinear four-wave mixing (4WM) process in hot atomic vapor.

Collimating three-axicon zoom system for interferometric Bessel beam side lobe cancellation

open access: yesOptical and quantum electronics
Optical Bessel beams are used in numerous applications like fluorescence microscopy, material processing and optical trapping. These applications require Bessel beams having a central core with defined full width at half maximum and a defined axial ...

Dielectrophoresis Tutorial: Inspired by Hatfield's 1924 Patent and Boltzmann's Theory and Experiments of 1874

open access: yesELECTROPHORESIS, EarlyView.
ABSTRACT The first patent to describe dielectrophoresis (DEP) as a means and process to separate particles from a mixture was granted by the US Patent Office to Henry Stafford Hatfield in 1924. The novel methods of sample preparation and designs of electrode geometry covered by the patent's disclosures and claims describe the basis for most present‐day

New Stability Criteria for Event-Triggered Nonlinear Networked Control System with Time Delay

open access: yesComplexity, 2019
This note focuses on the stability and stabilization problem of nonlinear networked control system with time delay. To alleviate the burden of transformation channel and shorten the dynamic process simultaneously, an improved event-triggered scheme is ...

Microwave Assisted Fluidized Bed Spray Soaking and Gelatinization for Whole Grain Rice Fortification

open access: yesFood Frontiers, EarlyView.
Spray soaking of micronutrient solution (0.106 mg/ml) with the pre‐optimized processing condition resulted in a gain in iron content (21.25 mg of iron/kg), non‐significantly impacting its quality. ABSTRACT Extruded fortified rice kernel often differs in its physicochemical, soaking, and cooking properties from regular rice and is not preferred due to ...

Extrapolation Boundary Conditions for 2‐D Smoothed Particle Hydrodynamics

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
This paper introduces novel inflow, outflow, and wall boundaries for the WCSPH method. Utilising innovative concepts from finite volume methods, fluid properties of sequential dynamic particles with varying distances to boundaries are extrapolated to ghost and wall particles using first‐order Taylor series expansion.

Orbital angular momentum transformation of optical vortex with aluminum metasurfaces

open access: yesScientific Reports, 2019
The orbital angular momentum (OAM) transformation of optical vortex is realized upon using aluminum metasurfaces with phase distributions derived from the caustic theory.
