Valencia pectinmethylesterase (PME) fractions, B-PME, containing 36 and 13 kDa protein bands and U-PME, containing a 36 and 27 kDa protein bands, were used to de-esterify original pectin (O-Pec) from 73% degree of esterification (%DE) to 63% (B-Pec) and 61% DE (U-Pec), respectively. Most O-Pec eluted from ion exchange chromatography at low salt concentration and a smaller component eluted at hi...

2D metal monochalcogenides have recently attracted interest for photoelectrochemical (PEC) applications in aqueous electrolytes. Their optical bandgap the visible and near-infrared spectral region is adequate energy conversion photodetection/sensing. large surface-to-volume ratio guarantees that charge carriers are photogenerated at material/electrolyte interface, where redox reactions occur, m...

A number of different approaches have been used in the stabilization of small band gap n-type semiconductors against photocorrosion in photoelectrochemical (PEC) cells. Such stabilization is necessary in the design of practical cells for conversion of solar energy to electricity, and is of critical importance in photoelectrosynthetic systems where the photogenerated holes produce species (e.g. ...

stress and residual stress are the main problems in the operating performance of materials. they are the principal causes of material failure and can affect life time of component. however measurement or predictions of them are typically difficult. two common non-destructive methods, x-ray diffraction and ultrasound are not reliable methods for subsurface residual stress measurements and destru...

Interconnection network is a decisive component of parallel and distributed computer systems. With the merits of simplicity and eeciency, 2-dimensional (2-D) mesh has been a popular choice of large MIMD interconnection networks. Mesh, however, has its known weaknesses in scalability and connectivity. Packed Exponential Connections (PEC) is a newly proposed network which is designed to improve t...

The photoelectrochemical (PEC) responses of electron-irradiated 66-phenyl-C61-butyric acid methyl ester (PCBM)/TiO2 electrodes were evaluated in a PEC cell. By coating PCBM on TiO2 nanoparticle film, the light absorption of PCBM/TiO2 electrode has expanded to the visible light region and improved the PEC responses compared to bare TiO2 electrode. The PEC responses were further improved by irrad...

Porcine enteric calicivirus (PEC) is associated with diarrhea in pigs, and to date it is the only cultivable enteric calicivirus (tissue culture-adapted [TC] PEC/Cowden). Based on sequence analysis of cDNA clones and reverse transcription-PCR products, TC PEC/Cowden has an RNA genome of 7,320 bp, excluding its 3' poly(A)(+) tail. The genome is organized in two open reading frames (ORFs), simila...

Parietal epithelial cells (PEC) are major constituents of crescents in crescentic glomerulonephritis. The purpose of these studies was to establish an immortalized PEC cell line with similar characteristics to PEC in vivo for use in future mechanistic studies. Glomeruli were isolated from H-2Kb tsA58 transgenic mice (ImmortoMouse) by standard differential sieving, and several candidate PEC cell...

Plasmonic nanostructures are highly used for sensing purposes since they support plasmonic modes which make them highly sensitive to the refractive index change of their surrounding medium. Therefore, they can also be used to detect changes in optical properties of ultrathin layer films in a multilayer plasmonic structure. Here, we investigate the changes in optical properties of ultrathin film...
