This chapter gives an overview of the importance of nanostructures, including nanocrystals and nanoporosity, in relation to specific properties achievable. The properties dealt with in this chapter comprise bioactivity, anti-bacterial properties, microleakage, haemocompatibility, and controlled drug delivery. 8.1 Nano…
Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.
In ihrer Zuschrift auf S. 9016 ff. beschreiben K. Sugiyasu, M. Takeuchi et al. die Mikrophasentrennung in Polythiophen-Copolymeren mit nichtfunktionalisierten und abgeschirmten Blöcken. π-π-Stapelung der nichtfunktionalisierten Blöcke führt zu einem Ensemble gestapelter und isolierter Polythiophene.
The nervous system has numerous functions including coordination and regulation of homeostasis of systems such as the respiratory, digestive, circulatory, and endocrine systems to name a few. The nervous system also mediates movement and provides mechanisms for sensory perception. In addition, innate and acquired beha…
The electrochemical organic memristive device with polyaniline active layer is a stand-alone device designed and realized for reproduction of some synapse properties in the innovative electronic circuits, including the neuromorphic networks capable for learning. In this work, a new theoretical model of the polyaniline…

The share of unreacted cement in the compacted body, initially zi, is under the assumption that no cement is hydrated during the compaction, as follows: zi = z0(1 – y) (7.1) Since the volume share of cement that the water y can hydrate is zh = y/k (7.2),the fraction of unhydrated cement after hydration will be z = zi…
Devido aos problemas ambientes causados pelos plásticos sintéticos, existe atualmente uma busca pela substituição desses materiais por materiais biodegradáveis. O estudo em relação a compósitos e nanocompósitos formados por materiais biodegradáveis e matrizes sintéticas vem crescendo nos últimos anos. Tem-se demostrad…
We present a formalism for understanding the elecromagnetism of metasurfaces, optically thin composite films with engineered diffraction. The technique, diffractive interface theory (DIT), takes explicit advantage of the small optical thickness of a metasurface, eliminating the need for solving for light propagation i…
The recent discovery of Dirac semimetals represents a new achievement in our fundamental understanding of topological states of matter. Due to their topological surface states, high mobility, and exotic properties associated with bulk Dirac points, these new materials have attracted significant attention and are belie…

The energy bands, charge and spin density distributions of topological Dirac semimetal (TDS) nanostructures are numerically calculated based on the tight-binding low-energy effective Hamiltonian. Anisotropic finite size effects are found in these systems, which is attributed to the different electronic and spin struct…
V diplomskem delu smo predstavili obnovo jeklenih konstrukcij v 400 kV redudantnem in transformatorskem stikaliscu Nuklearne elektrarne Krsko, ki je del celotnega stikalisca ob jedrski elektrarni. V uvodu smo predstavili jeklo kot material, napad korozije na jeklo, spa-janje jeklenih konstrukcij, vplive za nastanek ko…
The Focus of this research is on mathematical analysis of life of gears and reducing noise frequency of gears due to change of material from C-45 to 19mncr5.Calculations for gears life was done with the help of Lewis equation and Buckingham formula.Basically life of a gear is depending upon the stress, more the stress…
Poly(N-isopropylacrylamide) (PNIPAM) belongs to a class of stimuli-responsive materials known as “smart” polymers. When cast in the form of a hydrogel, PNIPAM’s lower critical solution temperature (LCST) of 32°C serves as a threshold for volumetric change. For solution temperatures below LCST, PNIPAM hydrogels exist a…
Magnetic shape memory alloys are a class of shape memory alloys, and therefore exhibit a thermoelastic martensite phase transformation between symmetric and asymmetric crystalline states induced by appropriate temperature and/or stress changes. Shape memory alloys are able to recover strain when stress is applied, whi…
