Melanin biopolymers are currently the focus of growing interest for a broad range of applications at the cutting edge of biomedical research and technology. This Special Issue presents a collection of papers dealing with melanin-type materials, e.g., polydopamine, for classic and innovative applications, offering a stimulating perspective of current trends in the field. Besides basic scientists...

Cellulose represents the most abundant renewable and biodegradable polymeric material on earth. Due to its low cost and functional versatility, cellulose has been a key feedstock for the production of chemicals with various properties and applications over the past century. In 2000, the world produces 187 million tons of wood pulp annually. Most of it is used as raw material in the production o...

In the past few years, spiropyran has emerged as the molecule-of-choice for the construction of novel dynamic materials. This unique molecular switch undergoes structural isomerisation in response to a variety of orthogonal stimuli, e.g. light, temperature, metal ions, redox potential, and mechanical stress. Incorporation of this switch onto macromolecular supports or inorganic scaffolds allows...

In the article we intend to present some recent achievements in the chemistry and physics of 3d and f electron mixed valence systems based on the Prussian blue in the field of molecular magnetism. Prussian blue is sometimes considered as the first coordination compound and in the paper we would like to demonstrate how it is possible to obtain completely new results based on the old one compound.

Self-assembly has emerged as a promising technique for fabrication of novel hybrid materials and nanostructures. The work presented in this thesis has been focused on developing nanoscale materials based on synthetic de novo designed polypeptides. The polypeptides have been utilized for the assembly of gold nanoparticles, fibrous nanostructures, and for sensing applications. The 42-residue poly...

in literature about inflation targeting, main factor is interest rate. in new surveys, price of some assets as housing is important in inflation targeting. iran inflation targeting is based on money changes and is not based on interest rate and housing price. in this paper, we want to survey problems of wrong policy of iran policy makers. we reveal that, using rate of deposit profit and growth ...
