A series of novel functionalised dumbbell-shaped bifullerenes in which two [5.0] pentakis-adducts of C60 are covalently connected by cyclic bismalonates were synthesised. These dimeric compounds, carrying various combinations of hydrophilic and hydrophobic addends, self-assemble in aqueous solution towards supramolecular architectures of different structural complexity as observed by cryogenic ...

Adhesion interactions during hematogenous dissemination of Candida albicans likely involve a complex array of host and fungal factors. Possible C. albicans factors include changes in cell surface hydrophobicity and exposed antigens that have been shown in static adhesion assays to influence attachment events. We used a novel in vitro shear analysis system to investigate host-pathogen interactio...

Studies have been carried out on the adsorption properties of plasma fibronectin (FN) on hydrophobic and hydrophilic surfaces. The hydrophobic and hydrophilic surfaces used were nonwettable bacteriological dishes and wettable tissue culture dishes, respectively. At low plasma FN concentrations, there was more plasma FN binding to hydrophobic surfaces than to hydrophilic surfaces. Under these co...

Co-adhesion between oral microbial pairs (i.e. adhesion of a planktonic microorganism to a sessile organism adhering to a substratum surface) has been described as a highly specific interaction, mediated by stereochemical groups on the interacting microbial cell surfaces, and also as a non-specific, critical colloid-chemical interaction. In a colloid-chemical approach, microbial co-adhesion is ...

AIM To evaluate the incidence of postoperative posterior capsular striae (PCS) and its influence on posterior capsular opacification (PCO) in patients implanted with two types of lens material. SETTING Tertiary eye care center in central rural India. STUDY DESIGN A prospective, observational, nonrandomized study. MATERIALS AND METHODS The study included 1247 patients having age-related ca...

The adhesion of methyl ricinoleate droplets to cells of the yeast Yarrowia lipolytica was investigated. A new cytometric method, relying on the double staining of fatty globules with Nile Red and of cells with Calcofluor, enabled us to quantify methyl ricinoleate droplet adhesion to cells precultured on a hydrophilic or on a hydrophobic carbon source. In this last case, droplet adsorption was e...

Core-shell microcapsules with combined features of hydrophilicity and hydrophobicity have become much popular. However, the assembly biocompatible edible materials in hydrophilic-hydrophobic core-shell is not easy. In this work, based on electrostatic interactions, we prepared controllable calcium alginate (ALG)-zein particles different shapes sizes using hydrophilic ALG hydrophobic zein by a t...

Surfaces that exhibit hydrophobic and hydrophilic characteristics are essential when developing Lab-onChip technologies. The availability of a droplet to be maneuvered on a surface develops from hydrophobic surface characteristics, while non-protein fouling characteristics are found in hydrophilic surfaces. By combining these traits, an ideal surface can be produced for biomedical applications....

Recovery of both latent heat and condensate from boiler flue gas is significant for improving boiler efficiency and water conservation. The condensation experiments are carried out to investigate the simultaneous heat and mass transfer across the nanoporous ceramic membranes (NPCMs) which are treated to be hydrophilic and hydrophobic surfaces using the semicontinuous supercritical reactions. Th...

Bacteria adhere to almost any surface, despite continuing arguments about the importance of physico-chemical properties of substratum surfaces, such as hydrophobicity and charge in biofilm formation. Nevertheless, in vivo biofilm formation on teeth and also on voice prostheses in laryngectomized patients is less on hydrophobic than on hydrophilic surfaces. With the aid of micro-patterned surfac...
