A new polymer/3D-foam-composite is presented for filling large gaps with high conformity and thermal conductivity, while rendering strong mechanical support.
We use the Dynamic Density-Functional Formalism and the Fundamental Measure Theory as applied to a fluid of parallel hard squares to study the dynamics of heterogeneous growth of non-uniform phases with columnar and crystalline symmetries. The hard squares are (i) confined between soft repulsive walls with a square sy…
A new synthetic route to prepare yttrium barium copper oxide superconductive fibers using electrospinning in conjunction with the polymerizable complex method was developed. The as-spun fibers exhibited wool-like tactility and were 5–7 µm thick. The fibers therefore exhibited sufficient flexibility to be fabricated in…

The development of targeted delivery systems releasing pharmaceutical agents directly at the desired site of action may improve their therapeutic efficiency while minimizing damage to healthy tissues, toxicity to the patient and drug waste. In this context, we have developed a bio-inspired microdevice mimicking the tu…
The upgrade of a PA/PS system based on the combination of reactive compatibilization of polymer components and their coupling with carbon nanoplatelets.
Stainless steels are iron-based alloys that contain a minimum of about 12% Cr. They have been classified by microstructure at room temperature. Two stainless steel grades 304 and 410L were studied in this paper. Hot rolling was performed on a Hille 100 experimental rolling mill under various reductions with considerat…
This recent work is to investigate the hardness and swelling behaviour of epoxidized natural rubber/recycled acrylonitrile-butadiene rubber (ENR 50/NBRr) blends. ENR 50/NBRr blends were prepared by two-roll mills with five different loading of NBRr from 5 to 35 phr. Results indicated that the hardness of ENR 50/NBRr b…
Micro porous gel type polymer electrolytes composed of 80 Wt% PVDF-HFP polymer - 20 Wt% LiBF4 salt in different concentrations of EC plasticizer (10Wt% - 70 Wt %) plasticizer have been synthesized by Solution cast technique. The effect of plasticizer in polymer-salt matrix, structural, morphological and ionic conducti…
A Pt@C–O catalyst with oxidized species of carbon and platinum obtained in two-phase synthesis exhibits regenerated CO anti-poisoning ability for MOR.
The stable slurry was prepared by ball-milling with a certain proportion of silica fume as silicon source,glucose as carbon source and metal niobium (Nb) as additives mixed with alcohol water. After the slurry was dried and pulverized, put the powder into a tubular furnace heated to 650℃ for 2h under nitrogen atmosphe…
In this study, CeO2 nanoparticles were modified by Fe3O4 and ZnO to enhance their sono- and sonophotocatalytic activity for degrading Methylene Blue dye pollutant. The molar ratio between Fe3O4, CeO2, and ZnO was 0.05:1:1, 0.1:1:1, 0.3:1:1, 0.5:1:1. The ternary Fe3O4/CeO2/ZnO nanocomposites with various molar ratios w…

The evolutions of texture, microstructure as well as mechanical properties of an Al-Mg-Si-Cu alloy during hot and cold rolling were investigated by TEM, EBSD and X-ray diffraction in this study. The results revealed that formation of sub-grain boundaries and //RD fiber texture after hot rolling is beneficial to the in…
Palm tree consists of different parts among which are the leaflet, rachis and fibers. All these parts constitute lignocellulose biomass components capable of producing value added end products. A kinetic study of thermal decomposition of UAE date palm tree of phoenix dicteylifera species was carried out using thermal…
We herein report an example of sequential dynamic higher structuralisation from disordered droplets into higher-ordered structures, resulting in the formation of a hydrogel. This is a potential model for understanding complicated biosystems in which lower-ordered structures evolve into higher-ordered structures that i…
It has been demonstrated that the microstructure and macrosegregation of ingot produced by direct chill casting would take remarkable effect on its deformation behavior. In the present study, the influence of casting speed and temperature on the microstructure and macrosegregation of AZ81 ingot prepared by a self-desi…
In the present work, innovative photocatalytic processes were developed for the abatement of harmful N-containing compounds, focusing on selectivity towards innocuous N2, to be applied for the treatment of waste waters to meet legislative specifications. The photocatalytic performance of the samples has been checked f…
Salen ligand synthesized from 2-hydroxybenzaldehyde and 2-hydroxy-1-naphthaldehyde was used as a palladium chelating ligand for the immobilization of the catalytic site. Mesoporous silica supported palladium catalysts were prepared by immobilizing Pd(OAc)2 onto a mesoporous silica gel through the coordination of the i…
Abstract Functional polyketones were chemically cross-linked for the softening of hard water, i.e. for the removal of the divalent cations Ca2+and Mg2+. Elemental analysis, FT-IR spectroscopy, solubility- and swelling-experiments were used to demonstrate the occurrence of the cross-link reaction. Testing the different…
