Effects of Statically Electric Fields on Freezing Parameters and Microstructures of Button Mushrooms (Agaricus bisporus)

Background and Objectives: Freezing under statically electric fields is one of the novel freezing methods to improve the quality of frozen products by controlling the nucleation process. The objective of this study was to investigate effects of freezing under electrostatic fields on the freezing parameters and microstructures of frozen button mushrooms. Materials and Methods: Mushroom samples w...

Dynamics of droplet motion under electrowetting actuation.

The static shape of droplets under electrowetting actuation is well understood. The steady-state shape of the droplet is obtained on the basis of the balance of surface tension and electrowetting forces, and the change in the apparent contact angle is well characterized by the Young-Lippmann equation. However, the transient droplet shape behavior when a voltage is suddenly applied across a drop...

Electrowetting films on parallel line electrodes.

A lubrication analysis is presented for the spreading dynamics of a high permittivity polar dielectric liquid drop due to an electric field sustained by parallel line electrode pairs separated by a distance R(e). The normal Maxwell stress, concentrated at the tip region near the apparent three-phase contact line, produces a negative capillary pressure that is responsible for pulling out a thin ...

Nonthermal ice nucleation observed at distorted contact lines of supercooled water drops.

Ice nucleation is the crucial step for ice formation in atmospheric clouds and therefore underlies climatologically relevant precipitation and radiative properties. Progress has been made in understanding the roles of temperature, supersaturation, and material properties, but an explanation for the efficient ice nucleation occurring when a particle contacts a supercooled water drop has been elu...

Production of Ice Nucleation Deficient (Ice-) Mutants of the Epiphytic Strains of Erwinia herbicola

To mutate the Ice Nucleation Active (INA) gene in Erwinia herbicola strains, Tn-5 transposon carried by Psup2021 plasmid was used. This plasmid was transferred to the bacterial cells by electroporation. Electrotransformation was carried out for 2.5 ms at 1800 v and 1 mm distance between the electrodes. Polymerase chain reaction was used for determination of presence or loss of INA gene, using a...
