Self-assembled monolayers (SAMs) on gold derived from the direct adsorption of thioacetic acid S-decyl ester (C10SAc) and thioacetic acid S-octadecyl ester (C18SAc) were compared to the corresponding SAMs derived from the analogous adsorption n-decanethiol (C10SH) and n-octadecanethiol (C18SH). All SAMs were characterized using ellipsometry, contact angle goniometry, polarization modulation inf...

Self assembly provides a simple route to organise suitable organic molecules on noble metal surface by using long chain organic molecules with various functionalities like -SH,-COOH,-NH2 , Silanes etc. These surfaces can be used to build up interesting nano level architectures. Self assembly is an interesting process for biological relevance because it provides a novel approach to complex struc...

Silver nanolayers were sputtered on polytetrafluoroethylene (PTFE) and subsequently transformed into discrete nanoislands by thermal annealing. The Ag/PTFE composites prepared under different conditions were characterized by several complementary methods (goniometry, UV-visible spectroscopy, X-ray photoelectron spectroscopy, and atomic force microscopy), and new data on the mechanism of Ag laye...

Ttiis is a useful book, in which the place of cortisone and other steroid drugs in the treatment of the rheumatic diseases is reviewed. The book falls naturally into two parts. The first section conisists of five chapters, and is concerned with the use of cortisone in rheumatoid arthritis. The second section consists of two chapters, the first of which decribes the general use of cortisone in d...

When the heart begins to contract, blood will be flowing into the chest as before, but the systolic pulse will not have reached the vessels at their outlets from the chest. The total result will therefore be that at this instant more blood will be within the chest than was the case before the commencement of systole, and in consequence of this air will leave the chest. As soon, however, as the ...

Acro-cardio-facial syndrome (ACFS) is a rare genetic disorder characterized by split-hand/split-foot malformation (SHFM), facial anomalies, cleft lip/palate, congenital heart defect (CHD), genital anomalies, and mental retardation. Up to now, 9 patients have been described, and most of the reported cases were not surviving the first days or months of age. The spectrum of defects occurring in AC...

The Cardio-vascular Tissues aimed for clinical use are submitted to the European Regulation (Directives 2004/ 23EC, 2006/17EC and 2006/86EC) to assure high level of tissue quality and security. The European Directive was transposed into the Member state legislation and Standards, specific to their needs and possibilities. The Cardio-vascular tissues are recovered in the operating theatre or ano...
