In the present research, the D-(+)-Glucose–confined water nanodroplets with mean size in the range of 6-11 nm were synthesized at D-(+)-Glucose different concentrations by AOT reverse micelles (RMs) method as a function of mass fraction of droplet (MFD) at the constant water-to-surfactant molar ratio ( W=40). The dynamic light scattering of the nano-sized water droplets containing the D-(+)-Glu...

The interaction between xylan and cellulose microfibrils is important for secondary cell wall properties in vascular plants; however, the molecular arrangement of xylan in the cell wall and the nature of the molecular bonding between the polysaccharides are unknown. In dicots, the xylan backbone of β-(1,4)-linked xylosyl residues is decorated by occasional glucuronic acid, and approximately one...

The mode of neocarzinostatin-chromophore (NCS-chr)-apo-neocarzinostatin (apo-NCS) interaction in neocarzinostatin (NCS) complex has been described. The NCS-chr release from the NCS complex in the presence of various reagents, which destroy the high-order structure of the protein under various pH conditions, was examined. We found that (i) sodium dodecylsulfate, Nonidet P 40, 8 M urea, and 2-pro...

Abstract Hydrophilic polymer coatings on artificial implants generate excellent tribological properties. The friction properties of are affected by salt ion factors. Herein, the atomic force microscopy (AFM) was used to show that superlubricity achieved between poly(vinylphosphonic acid) (PVPA)-modified Ti6Al4V and polystyrene (PS) microsphere probe lubricated with monovalent solutions (LiCl, N...

purpose: to compare the optical properties of hydrophilic and hydrophobic intraocular lenses (iols) containing uv-absorber and to determine their chemical composition. methods: optical properties of different foldable hydrophilic and hydrophobic as well as non-foldable hydrophobic polymethylmetacrylate (pmma) iols were evaluated in three powers of 15, 22 and 25 diopters. optical properties were...

polyacrylonitrile (pan) membranes with nano-porous surface and high hydrophilicity were fabricated by addition of polyoxyethylene (40) nonylphenyl ether (igepal) as an additive in the casting solution. the membranes were prepared from pan/igepal/1-methyl-2-pyrrolidone (nmp) via phase inversion induced by immersion precipitation technique. pure water was used as coagulation medium. the effects o...

Zwitterionic peptides emerge as a class of highly effective antifouling material in wide range applications such biosensors, biomedical devices, and implants. We incorporated neutral amino acid spacers with different hydrophobicities, including serine (Ser), glycine (Gly), leucine (Leu), into zwitterionic lysine–glutamic repeating units investigated the structure performance peptide brushes by ...

BACKGROUND Following the terror attack on Utøya on 22 July 2011, the Norwegian Directorate of Health recommended a proactive model of follow-up in the municipalities. According to this model, crisis teams were to rapidly contact the survivors, and all survivors were to be assigned a fixed contact person in the municipality. The aim was to ensure early assistance and continuity of follow-up. In ...

A facile method to prepare a polar stationary phase for hydrophilic interaction chromatography (HILIC) was proposed by coating polyvinyl alcohol onto silica particles (PVA-Sil). A water or organic solvent-insoluble permanent PVA coating on the silica particle surface can be formed simply by dipping silica particles into a hot PVA solution and then settled from this solution, leaving a thin laye...
