with the peak power loads on divertor targets will be unacceptable high for the given choice of plasma facing materials, namely Be and W. The JET first wall and divertor plasma facing components, currently made of carbon fibre-composite, will be substituted by similar plasma facing components made of beryllium and tun…
Objective To investigate the effect of penetration enhancers on the percutaneous absorption of artesunate,and provide a reference for the development of artesunate transdermal delivery systems.Methods Penetration enhancers(in different concentrations) were incorporated into a 25% w/w artesunate matrix patch formulatio…
Reaction of aqueousmetal (Ni(II),Co(II), Cd(II), Zn(II), Cu(II) andMn(II)) nitrate/ acetate solution with an aqueous solution mixture of hydrazine and 2-hydroxy - 1- naphthoic acid yielded the complexes with formula, (N2H5)2[M{C10H6(COO)(O)}2(H2O)2] whereM(II) = Ni, Co, Cd, Zn, Cu and Mn in the pHrange of 4-7 and [M(N…
The paper approaches the environment issue in the context of welding fabrication processes.The introduction presents, synthetically, the place and dimension of welding in the manufacturing industry.Negative aspects regarding the image of welding due to the impact on the environment are identified.The driving factors a…
Vrste konstrukcijskih polimernih materijala. rednosti, nedostaci i karakteristicna svojstva. Specificnosti konstruiranja s polimernim materijalima. Primjeri konstrukcijskih primjena.
This paper discusses the formation of complex geometry electrode structures on piezoelectric ceramic substrates using nanosecond pulsed laser ablation. Optical microscopy, scanning electron microscopy and surface profiling are used to examine the impact of the laser ablation process onto the substrate material. The in…
The synergistic combination of polymers and inorganic compounds via sol-gel process has attracted great attention, by manipulating structure at molecular level, for developing new materials with desired properties.These new hybrid materials could have a controllable combination of the benefits of polymers (flexibility…
Welding residual stress is occurred after welding process. Tensile residual stress is one factor of PWSCC. Repair welding usually happened during the manufacturing welding process. Repair welds cause strong tensile residual stress. In PWR, Repair weldments made by Alloy 82/182 is susceptible to PWSCC caused by tensile…
CalciummodifiedBaTiO3 (BT) ferroelectric systemwas synthesized by partial precipitation route. For single perovskite phase and dense grain morphology formation 9000Cand 13000C temperatureswere optimized as calcination and sintering temperatures, respectively. Dense packing of grains with average grain size i¾13.3i…
A water-emulsified terpinene-maleic ester type epoxy resin (TME) was prepared by phase-inversion emulsification,and a self-designed emulsifier prepared by TME modified with PEG was used as reactive emulsifier in this emulsion. The relationship between conductivity and micro-morphology in the emulsifying process was an…
The present tendency of the mining industry to design and evolve their production systems to minimise the use of water has resulted in the need for an assessment of efficient paste and thickened tailings disposal sites. This paper proposes a dimensionless variable and a length model for slow laminar Bingham flows. Res…
With the increasing environmental concern, replacing the traditional non-biodegradable synthetic materials for biodegradable products is the challenge for many researchers and companies. Starch is considered one of the most promising natural polymers for packaging application because of its renewability, biodegradabil…
The pressure-dependent structural properties under hydrostatic pressure up to 120 GPa and the decomposition under uniaxial compression along the b lattice vector up to 40 GPa of nitromethane molecular...
We introduce a general class of mixture models to study water uptake, degradation, erosion, and drug release from degradable polydisperse polymeric matrices. The mathematical model is based on a finite number of constituents describing the polydisperse polymeric system, i.e. each representing collection of chains whos…
One of the main issues regarding the design of LFR is the corrosion-erosion behaviour of materials in contact with high temperature and high velocity lead, such as pump impeller and bearing materials. Those materials will worked in Lead at about 480°C with a velocity relative to impeller blade in the magnitude of 10m/…

In order to fully exploit the potential of polymer electronics, large-area/low-cost processing technologies are necessary. In this paper, we investigate the feasibility of air atomizing spray technology for large-area/low-cost fabrication of organic electronic and optoelectronic thin-film devices based on solution-pro…
