Verkleinert man den Durchmesser von Fasern bis in den Nanobereich, so verändert man ihre Eigenschaften. Die offensichtlichste ist die Vergrösserung der Faseroberfläche, die sich zur Steuerung von Vorgängen an Oberflächen nutzen lässt – von der Benetzbarkeit über die kontrollierte Abgabe und Aufnahme von Geruchsstoffen…
Visible absorption and circular dichroism measurements of the title compounds, conducted in aqueous solution at neutral pH, showed that both ligands maintained their “glycine-like” configuration, i.e. they were bonded to Cu(II) via the amino nitrogen and carboxylato oxygen atoms, and formed bis-complexes.[1] This coor…
Bone tissue is a complex structure with the capacity to self-regenerate and responsible for different functions in our body. However, when bone integrity is disturbed, its self-regenerative capacity is lost. The available treatments are based on bone grafts and other bone substitutes which possess several limitations.…

This paper describes the evaluation of the mechanical properties and flame retardancy on bio-based polymer compounds of Poly(lactic acid) (PLA) and Polyamide 11 (PA 11). A compounding technology and mechanical properties of PLA and PA 11 using a compatibilizer were firstly studied to improve the thermal resistance and…
The article considers the to enhance the efficiency the thermoelectric heat pump by making the branches of semiconductor p- and n-type as nanofilms and creating conditions for the emergence of additional thermoeffect between the hot and cold junctions of dissimilar metals that will create a more efficient heat pumps w…
Conductive polymers have been studied extensively during recent years. Especially,poly(3,4-ethylenedioxythiophene) (PEDOT) have found many application areas and arebroadly considered one of the most promising conductive polymers. In order to broadenthe application field of PEDOT we have developed an azide functional p…
The thermo-oxidative degradation of PBT molded parts has already been evaluated in relation to mileage. However, in this study we attempted to evaluate thermo-oxidative degradation in relation to the product of thermal aging temperature and ageing time by applying time-temperature superposition principle law. The foll…
In order to improve the education, training and communication processes for informed behavior and decision-making related to ionizing radiation risk the European Commission launched in August 2013 a coordination and support action called EAGLE (http://eagle.sckcen.be) under FP7-EURATOM. The project aims at revealing a…
The brittle fracture of the isotactic polypropylene (i-PP) injection molded sheet in the falling weight impact test is caused by the cracks formed along the orientation direction of the surface layer. The fracture of the i-PP sheet takes place even at room temperature at low displacement. It was well known that the i-…
In order to enhance the accuracy of precision injection molding, the authors proposed the "precision injection molding by cooling rate control" which enhances accuracy by controlling the shrinkage of molded products, and are studying the mechanism for realizing high precision. To date, we have investigated the shrinka…
It is well known that melt-blending of polypropylene (PP) with polycarbonate (PC) without a third component has very poor mechanical properties. That is, the tensile properties of PP are seriously weakened by blending the tougher component (PC). We found that, by adding hydrogenated styrene-butadiene-styrene block cop…
The research is aimed at developing alternative tool from pack carburized low carbon steel. The tools were made from low carbon steel of 111,67 VHN using cutting machine and then sharpened. Carburizing process was conducted at temperature vary of 800, 850 and 900 0C for 1, 2 and 3 hours and then quenched into water an…
This article deals with implementation of Scanning Probe Microscopy (SPM) techniques to the characterization of crystalline silicon solar cells. Atomic Force Microscopy (AFM) is used for the characterization of solar cells texture, because it allows three dimensional imaging of surface structure [1]. Aim of this part…
Ce rapport en deux tomes détaille les résultats de l’évaluation, avec les règles de la DCE (Directive Cadre sur l’Eau), de l’élément de qualité phytoplancton dans les masses d’eau de la France métropolitaine. Cette évaluation est réalisée à partir des données acquises sur la période 2007-2012. Le tome 1 contient égale…
Recently, the use of bio-based nanomaterials has attracted much interest in medical applications due to their cytocompatibility, good moisture stability, good mechanical properties, hydrophilic surfaces and their ability to form porous structures. The aim of this work is to develop porous nanocomposites based on nanoc…

Used nuclear fuel contains radiotoxic elements with lifetimes in the range of 100 000 years. Although possibilities for recycling of the fuel exist, a final storage for the ultimate high-level waste will be necessary. In Sweden, a deep geologic repository will be constructed, in which the used fuel will be protected f…
