Silks are being reassessed as biomaterial scaffolds due to their unique mechanical properties, opportunities for genetic tailoring of structure and thus function, and recent studies clarifying biocompatibility. We report on the covalent decoration of silk films with integrin recognition sequences (RGD) as well as para…

Carbon dioxide is a clean and versatile solvent for the synthesis and processing of a range of materials. This review focuses on recent advances in polymer synthesis and processing using liquid and supercritical CO2. The synthetic techniques discussed include homogeneous solution polymerisation, precipitation polymeri…
Over the past twenty years, polypyrrole has appeared as the most extensively studied conducting polymer. However, despite the volume of work already done in this area, there has been little focus put on the mechanism of polypyrrole synthesis, especially concerning the most efficient method, electropolymerization. Nume…
Thin films of manganese dioxide were formed on nickel foils by electrodeposition and by both dip‐coating and drop‐coating with manganese dioxide suspensions (sols) and their subsequent gelation and calcination. The performance of these films as ultracapacitors was studied by cyclic voltammetry in the range 0.0–0.9 V (…

The behaviour of spin crossover compounds is among the most striking and fascinating shown by relatively simple molecular species. This review aims to draw attention to the various ways in which spin crossover phenomena are manifested in iron(II) complexes, to offer some rationalisation for these, and to highlight the…
A series of chitosan with different molecular weights obtained by γ-irradiation depolymerization and another series of deacetylated chitosan were synthesized. Several N,O-carboxymethylated chitosan and O-carboxymethylated chitosan were also produced. The above samples were characterized by Fourier transform infrared s…
A truly modern treatment of materials that can hold a magnetic field. Covers cutting-edge materials with many important technical applications. Includes examples and problems along with computer solutions.
The results of a systematic XPS study, under high controlled conditions, of different basic oxides of transition metals, alkali and alkaline-earth metals are presented; the XPS data of some hydroxides and peroxides are also reported. Variations of the O 1s binding energies are analysed and one point of interest is the…
Nanostructured Materials (NsM) are materials with a microstructure the characteristic length scale of which is on the order of a few (typically 1–10) nanometers. NsM may be in or far away from thermodynamic equilibrium. NsM synthesized by supramolecular chemistry are examples of NsM in thermodynamic equilibrium. NsM c…
El estudio comparativo de la cristalinidad de la illita calibrada en las escalas Kubler y CIS realizado en el presente articulo pone en evidencia las diferencias existentes entre los valores limite de la anquizona para ambas escalas. La adopcion de la escala CIS para la determinacion de la cristalinidad requiere la re…
Chitin- graft -poly(2-methyl-2-oxazoline)/poly(vinyl alcohol) (PVA) blends were characterized by means of analytical pyrolysis techniques such as temperature-programmed pyrolysis−mass spectrometry (TPPy−MS), TPPy−gas chromatography (TPPy−GC) and Py−GC mainly in terms of their miscibility and the site of the intermolec…
A partial monolayer of Au strongly modifies the kinetics of water adsorption and formation on the stepped Pt(335) surface. The effects are more than passivation. With a Au coverage of 0.7 ML as measured by Auger spectroscopy, saturation H and O adsorption are only 15% and 8.5%, respectively, of their values on bare Pt…

A phase field concept for interface motion in general multi-phase systems with anisotropic interfacial energy is studied. We allow the anisotropy to be even crystalline which leads to a polygonial Wulff shape. A sharp interface model which appears as the limit of small interfacial thickness is stated. Through a series…

The structure of micelles of an asymmetric polystyrene−polyisoprene (PS−PI) diblock copolymer has been studied in di- n -butyl phthalate (DBP), which is a slightly selective solvent for PS. The polymer has a molecular weight of 11 500 for the fully deuterated d -PS block and 48 500 for the PI block. Contrast variation…
Artificial photosynthetic reaction centers have been constructed on a protein surface by cofactor reconstitution, which mimic the function of photosynthetic organisms to convert light energy to chemical potential in the form of long-lived charge-separated states. They feature a ruthenium tris(2,2‘-bipyridine) moiety a…
