We review past and recent progress in Nano-Imprint Lithography (NIL) methods to (nano-) structure inorganic materials from sol-gel liquid formulations colloidal suspensions onto a surface. This technique, first inspired by embossing techniques, was developed for soft polymer processing, as final or intermediate materials, but is today fully adapted hard with high dielectric constant, such metal...

INTRODUCTION The research made in this PhD thesis fits the current trend in the development of new advanced composite electrode materials with high performance and parameters. The composite materials has new physical and chemical properties that are not present in its components taken individually. The new electrode materials were obtained by combination of conducting polymers, such as polypyrr...

Because of their inherent rigidity and brittleness, inorganic materials have seen limited use in flexible thermoelectric applications. On the other hand, for high output power density and stability, the use of inorganic materials is required. Here, we demonstrate a concept of fully inorganic flexible thermoelectric thin films with Ca3Co4O9-on-mica. Ca3Co4O9 is promising not only because of its ...

PURPOSE The aim of the present study was to synthetize and characterize novel sol-gel organic-inorganic hybrid materials to be used for controlled drug delivery application. MATERIALS AND METHODS Organic-inorganic hybrid class I materials based on poly(epsilon-caprolactone) (PCL 6, 12, 24 and 50 wt%) and zirconia-yttria (ZrO2-5%Y2O3) were synthesized by a sol-gel method, from a multicomponent...

Introduction The deterioration process of inorganic materials induced by microorganisms, including glass, marble, concrete, sandstone, tufa, and metals, can cause various alterations such as crust formation on surfaces, change of hue, discoloration, and loss of materials, leading to structural damage (Figure 1). These severe problems are due to the excretion of aggressive metabolic products suc...
