We demonstrated a liquid lens whose focal length can be controlled by an actuator. The lens cell is composed of elastic membrane, planar glass plate, a periphery sealing ring, and a liquid with a fixed volume in the lens chamber. Part of the periphery sealing ring is excavated to form a hollow chamber which functions as a reservoir. This hollowed periphery is surrounded by an exterior rubber me...

The transport of carbonate ions through a supported liquid membrane in the presence and absence of carriers has been explored. The liquid membrane used was the combined liquid cation and anion exchangers in toluene immobilized in the porous polypropylene support. The permeability coefficient (P) of carbonate ions transport from the source to receiving through membrane phase has been estimated. ...

As part of our continuous effort to elucidate the biochemical and immunological nature of human sperm surface antigens, monoclonal antibodies to human spermatozoa were generated by improved hybridoma techniques. Following immunizations with the membrane fraction of human spermatozoa and cell fusions, hybrid cells were cultured in a semi-solid HAT-selection medium to maximize the number of monoc...

To study the role of the signal sequences in the biogenesis of outer membrane proteins, we have constructed two hybrid genes: a phoE-ompF hybrid gene, which encodes the signal sequence of outer membrane PhoE protein and the structural sequence of outer membrane OmpF protein, and a bla-phoE hybrid gene which encodes the signal sequence as well as 158 amino acids of the structural sequence of the...

Colloidal rods immersed in a thermotropic liquid-crystalline solvent are at the basis of so-called hybrid liquid crystals which characterized by tunable nematic fluidity with symmetries ranging from conventional uniaxial or anti-nematic to orthorhombic [Mundoor et al., Science 360, 768 (2018)]. We provide theoretical analysis elastic moduli such systems considering interactions between individu...

A novel hybrid fuel cell is described using at least one electrode operating at high pH in an effort to use the high conductivity of Nafion and exploit the electrochemical advantages of high-pH operation. The electrochemical behavior of a hybrid anion exchange membrane (AEM)/proton exchange membrane (PEM) junction and corresponding fuel cell are presented. Two AEM/PEM junctions and fuel cells h...

An ionic liquid (IL) is a salt in the liquid state. In some contexts, the term has been restricted to salts whose melting point is below some arbitrary temperature, such as 100 °C. While ordinary liquids such as water and gasoline are predominantly made of electrically neutral molecules, ionic liquids are largely made of ions and short-lived ion pairs. These substances are variously called liqu...
