Abstract: A new approach is presented to reduce encrustation of catheters by the application of nanoparticles. It is demonstrated that the negatively surface charged nanoparticles produce coating films comprised of long-range domains in which the nanoparticles are self-assembled into a mosaic-like order, showing a relatively small tendency to agglomerate.

Abstract: Novel compounds having a functionalized group capable of binding to a solid substrate; a photoactivatable group capable of generating a reactive group upon exposure to light and being for binding a screenable moiety; and a polymer capable of forming a monolayer on a solid substrate, and having the functionalized group and to the photoactivatable group attached thereto and processes for the preparation thereof are disclosed. Further disclosed are arrays of screenable moieties (e.g., nucleic acids, proteins, carbohydrates, substrates, chelating agents and many more) prepared using these novel compounds.

Abstract: The present invention provides a method for producing carbon structures by laser irradiation, the method comprising: (i) providing a substrate, at least a portion of whose surface being covered with a sample comprising one or more thermally degradable organic compounds, said sample being in the form of homogeneous solution, suspension or emulsion; (ii) irradiating said covered surface portion locally by applying a focused laser beam, thus resulting in local deposition of carbon, and (iii) repeating step (ii) by moving either the laser beam or the sample, thus creating a desired pattern of carbon structures. The present invention further provides carbon structures produced by the method of the invention.

Abstract: The present invention relates to a process for the resolution of DL-racemic mixtures of compounds which crystalize in the form of a conglumerate. Both, the D and L-enantiomers are obtained according to the invention in a industrially feasable process by adding chiral enantioselective polymers to the supersaturated solution of the racemat to inhibit crystalization of one enantiomer. Next a DL-racemic mixture of said compound is suspended in about twice the amount of the crystallized enantiomer. Consequently, the opposite enantiomer could be recovered by said suspension by physical separation.

Abstract: The invention relates to a process for the kinetic resolution of D,L-racemic mixtures of racemates crystallizing as conglomerates. Resolution is effected from supersaturated solutions of these which is carried out in the presence of a polymer bound inhibitor of crystallization of the one form, resulting in the preferred crystallization of the one form, and when the other form is desired - in the presence of such inhibitor for the other form. Amongst racemic mixtures amenable to this process are amino acids. The process can be carried out in a two-compartment device, where the compartments are separated by a membrane which is permeable to the constituents of the racemate, while it is impervious to the polymer-bound inhibitor for the crystallization of one of the racemic forms.
