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…

Kerusakan pada bagian permukaan hinge arm dapat menyebabkan kecelakaaan…
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…
The association of nanoparticles with polymer blends offers significant features beyond the advantages of polymer composites prepared by single homopolymer. Since the blends undergo phase separation due to incompatibility of the constituent polymers into various internal structures, the particles can be segregated int…
The effect of poly(tetrafluoroethylene)(PTFE) content as a filler on rheological and mechanical properties for polypropylene(PP)/corn starch (CS) composite was studied. Two kinds of PTFE were adopted. A small amount of virgin PTFE component inhibits the strain softening in uniaxial elongation viscosity for PP/CS compo…

Computational chemists frequently use molecular simulations in \ncomputer-aided drug design. As input, these simulations require \nmolecules that have been parameterised with atom charges. Typically, \nthese charges are obtained from complex quantum-mechanical calculations, \nwhich are only feasible for small molecule…

Nanoencapsulacao e um processo adequado para reduzir a degradacao de componentes instaveis. Neste estudo, nanoparticulas (NPs) de quitosana e trimetilquitosana com tripolifosfato foram utilizadas para encapsular vitaminas C, B9 e B12. Por meio de espectroscopia de UV-Visivel, o estudo de liberacao mostrou perfis difer…
Hydrogen has long been touted as an alternative fuel which could form the basis of a sustainable energy system: the hydrogen economy. This thesis advances the application of light metal amide materials in the realisation of this transformative potential. One of the most vexing technical challenges to the widespread ad…
Diplomová práce se zabývá měřením šumových charakteristik předzesilovače pro detektorovou infrastrukturu v elektronových rastrovacích mikroskopech. Proměřením různých modifikací předzesilovače je zjištěno, která z variant má pro dané zesílení největší signálový zisk a nízkou úroveň šumu s ohledem na dosahovanou rychlo…
Táto práca sa zameriava na štúdium relaxačného správania polymérnych skiel. Ako typický zástupca polymérnych skiel bol zvolený polymetylmetakrylát. Relaxačné procesy boli študované pomocou dynamickej mechanickej analýzy a ako doplnková metóda bola použitá diferenciálna skenovacia kalorimetria. V termomechanických spek…
