We prepared the bioactive liquid crystal (LC) droplets by decorating an oligopeptide at the LC/aqueous interface to stabilize the LC droplets. These LC droplets can be used to detect proteases through the specific cleavage of protease on an oligopeptide leading to a bipolar-to-radial transition of LC configuration inside the droplets.

This study introduces liquid crystal (LC) Janus droplets. We describe a process for the preparation of these droplets, which consist of nematic LC and polymer compartments. The process employs solvent-induced phase separation in emulsion droplets generated by microfluidics. The droplet morphology was systematically investigated and demonstrated to be sensitive to the surfactant concentration in...

Numerical simulations are performed to determine the angular dependence of MIe scattering cross-section intensities pure water droplets and pollutants such as contaminated black carbon a function wavelength incident laser light, complex refractive index, size scatterer. Our results show distinct features when varying various parameters, thereby allowing identification particle with specific app...

This report is concerned with theoretical demonstration of the spontaneous emulsification which has been observed in a soft contact of nitrobenzene with water without surfactant [K. Aoki, M. Li, J. Chen, T. Nishiumi, Electrochem. Commun. 11 (2009) 239]. The demonstration is based on the model of spherical oil droplets with any size in equilibrium. The droplets are composed of the smallest dropl...

BACKGROUND Although insecticidal aerosols have been widely accepted for household use, the discharged amount should be maintained at minimum levels because they contain volatile organic compounds. Hence, it would be valuable to develop a technique whereby insecticide droplets adhere efficiently to an insect's body. The present study was undertaken in order to clarify how differences in the mode...

Insects often release noxious substances for their defence. Larvae of Zygaena filipendulae (Lepidoptera) secrete viscous and cyanogenic glucoside-containing droplets, whose effectiveness was associated with their physical and chemical properties. The droplets glued mandibles and legs of potential predators together and immobilised them. Droplets were characterised by a matrix of an aqueous solu...

Transport model of droplets injected axially or transversely into a plasma jet is presented. The droplets contain a ceramic precursor that precipitates in the vaporizing droplets. Droplet temperature and solute concentration distributions were predicted to estimate precipitation zones based on a homogeneous nucleation hypothesis. Effects of droplet size, injection velocity and injection angle w...

Abstract A method was proposed for preparing multiple emulsions based on a double parallel-crank mechanism. The dispersed phase flows into the glass capillary, and capillary driven to make circular motion via connecting crank structure. Then, external shears through mechanism prepare water in oil (W/O) droplets, process of generation droplets simulated by CFD. effects rotating speed, diameter, ...

Abstract The ALICE Collaboration measured three- and four-pion Bose-Einstein correlations (BECs) for Pb-Pb collisions at the Large Hadron Collider (LHC). It is speculated that observed significant suppression of multi-pion BECs owing to a considerable degree coherent pion emission in these collisions. Here, we study BEC functions granular sources with pion-emission droplets. We find intercepts ...

In this paper, we present TLBfind, a GPU code for simulating the hydrodynamics of droplets along with dynamic temperature field. TLBfind hinges on two-dimensional multi-component lattice Boltzmann (LB) model concentrated emulsion finite-size evolving in thermal convective state, just above transition from conduction to convection. The droplet concentration system is tunable and at core lies pos...
