Aluminophosphate zeolite is an artiicial material which shows strange hydrophilic-ity. We have been investigating the reason by quantum mechanics, and found that the hydrophilicity of this zeolite depended on the local geometric deformation, and speculated that the site-speciic hydrophilicity might be explained by diierences in the stiiness of the local deformation determined by the location wi...

Lithium niobate crystal surfaces become superhydrophilic after ultraviolet laser irradiation. The crystal surface hydrophilicity, which was assessed by the contact angle of a sessile drop of de-ionized water, was found to undergo a transition from mildly hydrophobic contact angle E 50° to a superhydrophilic state E 5° . Patterning of the hydrophilicity at the micron and submicron ranges has bee...

A method is presented for locating protein antigenic determinants by analyzing amino acid sequences in order to find the point of greatest local hydrophilicity. This is accomplished by assigning each amino acid a numerical value (hydrophilicity value) and then repetitively averaging these values along the peptide chain. The point of highest local average hydrophilicity is invariably located in,...

Hydrophilicity analysis of the surface properties of proteins continues to be an important means for understanding the interactions that occur between proteins and other macromolecules. We have shown that the procedure of Hopp and Woods is useful in developing synthetic peptide immunogens and for understanding the relationship of protein sequence and folding to the interactions between macromol...

Molecular dynamics simulations were performed for CO2 dissolved in water near silica surfaces to investigate how the hydrophilicity and crystallinity of solid surfaces modulate the local structure of adjacent molecules and the nucleation of CO2 hydrates. Our simulations reveal that the hydrophilicity of solid surfaces can change the local structure of water molecules and gas distribution near l...

Abstract Effect of retanning on the thermal stability leather is eliciting increasing attention. However, relationship between hydrophilicity agents and heat resistance corresponding mechanism remain unclear. Herein, phenolic formaldehyde syntans (PFSs) were selected as models to explore effect retanned leather. The was closely correlated hydrophilic group content (sulfonation degree) PFSs. As ...

Recently the potential of enzymes for surface hydrophilisation and/or functionalisation of polyethyleneterephthalate (PET) and polyamide (PA) has been discovered. However, there was no correlation between enzyme class/activity (e.g. esterase, lipase, cutinase) and surface hydrolysis of these polymers and consequently no simple assay to estimate this capability. Enzymes active on the model subst...
