Scalar fields provide an intuitive picture of chemical bonding. In particular, the electron localization function (ELF) has proven to be highly valuable in interpreting a broad range of bonding patterns. The discrimination between enhanced or reduced elect ...
Two protocols of covalent attachment of proteins onto the calcite surface, viz. one using the metallochelat and second using the aminohexil, are elaborated. Single molecule force spectroscopy method has been used to test their efficiency and practical appl ...
In this work time resolved luminescence measurements on the red phase of 3BCMU are presented. These polydiacetylenes form an ordered and isolated one dimensional model system. This work is divided in two parts. First we present an excitation spectrum in ch ...
needed. By an optimized patterning of the evaporated indium film and the lid, surface hermetic bonding on wafer level is reached without exceeding 140 °C in any step of the procedure. Different designs of the indium metallization and lid were tested to imp ...

A review. The catalytic activation of C-C single bonds represents a major challenge in organometallic chem. Strained ring substrates occupy in this respect a privileged role as their inherent ring strain facilitates the desired metal insertion. Employing s ...
Metal-free org. dyes bridged by anthracene-contg. π-conjugations were designed and synthesized as new chromophores for dye-sensitized solar cells (DSSCs). Studies on the relation between the dye structure, photophys. properties, electrochem. properties and ...
Homonuclear helicates with rare-earth-metal(III) ions or heteronuclear derivatives with rare-earth-metal and aluminium or zinc centres are obtained in alkali-metal-templated selfassembly processes from isobutenylidene- bridged homoditopic bis(2-carb-Gamido ...
We have previously shown that the switch from N-cadherin to OB-cadherin expression increases intercellular adhesion between fibroblasts during their transition from a migratory to a fibrogenic phenotype. Using atomic force microscopy we here show that part ...
During wound healing and in a variety of fibrocontractive diseases, fibroblasts differentiate into contractile myofibroblasts by acquiring stress fibers and by expressing α-smooth muscle actin (α-SMA). Myofibroblasts of wound granulation tissue, in contras ...
Alkylation of 2-hydroxydibenzofuran with 3-chloro-3-methyl-1-butyne, followed by Claisen rearrangement, gave access to 3,3-dimethyl-3Hbenzofuro[3,2-f][1]-benzopyran. Several derivatives modified at the pyran 1,2-double bond were prepared, including the cor ...
