Highly purified sodium channel protein from the electric eel, Electrophorus electricus, was reconstituted into liposomes and incorporated into planar bilayers made from neutral phospholipids dissolved in decane. The purest sodium channel preparations consisted of only the large, 260-kD tetrodotoxin (TTX)-binding polypeptide. For all preparations, batrachotoxin (BTX) induced long-lived single-ch...

CLIC-1 is a member of a family of proteins related to the bovine intracellular chloride channel p64 which has been proposed to function as a chloride channel. We expressed CLIC-1 as a glutathione S-transferase fusion protein in bacteria. The fusion protein was purified by glutathione affinity, and CLIC-1 was released from its fusion partner by digestion with thrombin. After further purification...

this paper is dedicated to propose an algorithm in order to generate the certain isomers of some well-known fullerene bases. furthermore, we enlist the bipartite edge frustration correlated with some of symmetrically distinct innite families of fullerenes generated by the oered process.

Planar and channel waveguides in ZnS single crystal are fabricated by 6.0 MeV C ion implantation with fluences of 5 × 1014 1 1015 ion/cm2 at room temperature. The optical modes for the planar measured using a prism coupler well-known m-line method. near-field light intensity profiles end-face coupling setup 633 nm 1539 nm. reflectivity calculation method finite difference beam propagation used ...

The BCL-2 family of proteins is composed of both pro- and antiapoptotic regulators, although its most critical biochemical functions remain uncertain. The structural similarity between the BCL-XL monomer and several ion-pore-forming bacterial toxins has prompted electrophysiologic studies. Both BAX and BCL-2 insert into KCl-loaded vesicles in a pH-dependent fashion and demonstrate macroscopic i...

Ion implantation in optical materials is increasingly used in fabrication of optical waveguides of micrometric dimensions. Implantation has been proved to form planar and channel waveguides in YAG single crystals [1, 2]. Planar waveguides are obtained by homogeneous irradiation of the crystal surface with He or H ions at a given energy (in the MeV range), while mask technique has to be used to ...

Phospholipid vesicles fuse with a planar membrane when they are osmotically swollen. Channels in the vesicle membrane are required for swelling to occur when the vesicle-containing compartment is made hyperosmotic by adding a solute (termed an osmoticant). We have studied fusion using two different channels, porin, a highly permeable channel, and nystatin, a much less permeable channel. We repo...

The purified NmpC outer membrane protein from Escherichia coli, when incorporated into planar lipid bilayers, gave rise to channels with a single-channel conductance of 1.8 nS in 1 M KCl. This suggests that the NmpC protein is a porin.

This paper presents a comparison of the density performance-degrading near-interface traps (NITs) in most commonly available 1200 V commercial N-channel SiC power metal–oxide–semiconductor field-effect transistors (MOSFETs). A recently developed integrated-charge technique was used to measure NITs with energy levels aligned conduction band, which degrade MOSFET’s performance by capturing and re...

This paper investigates the short channel effects (SCE) of recently proposed Singular Point Source MOS (S-MOS) SiC MOSFET. The study was carried out using 2D and 3D TCAD simulations for a planar, trench S-MOS 1200V MOSFETs IV output characteristics up to under circuit transient conditions. device shows no SCE rated voltage when compared reference planar devices which exhibit strong SCE. is due ...
