Composite panel walls with both combustible and non-combustible cores were subjected to fire resistance test to EN 1364-1. The results revealed that the combustible-core panels started emitting smoke on the unexposed side due to the presence of joints between panels. In some cases the smoke emission started early afte…
Preliminary fire experimental tests have been carried out on steel plates protected with intumescent coating. The tests evaluated and measured the heating of steel plates with various geometrical configurations: shape, size. A first test on an equal leg angle section showed interesting results with different coating e…
Abstract Der kathodische Korrosionsschutz (KKS) ist eine weitverbreitete Methode um Bauteile vor Bewehrungskorrosion zu schützen. Er hat sich im Verlaufe des letzten halben Jahrhunderts als ein bewährtes System für Schutz und Instandsetzung von Stahlbetonbauteilen insbesondere bei chloridinduzierter Korrosion etablier…
Catalytic combustion of diesel particulate matter was performed over a cobalt (II,III) oxide (Co3O4) catalyst in a thermogravimetric analysis system, at distinct heating rates and catalyst contents. Kinetic parameters were then estimated for several experimental conditions, based on the Flynn-Wall-Ozawa method. These…
The combination of the properties of graphene oxide (OG) and PVDF homopolymer makes their combined composite materials as multifunctional systems with great potential. Knowledge of the molecular structure is essential for better use. In this work, the degradation of PVDF polymer exposed to gamma irradiation in oxygen…
Plasma experiments conducted on the PF-1000 device generate the release of neutrons and ionizing radiation that are the source of immediate exposure to personnel. Neutron activation of materials in the research device and the surroundings is a source of ongoing radiation exposure to the same personnel. Having reported…
In order to further study the influence of factors on the braking torque of liquid-cooled eddy current retarder (ECR) with dual salient poles, this paper applies electromagnetic theory to deduce the braking power and calculation formulas of braking torque considering the structural features of ECR with dual salient po…
Polyvinyl chloride (PVC) is a common thermoplastic whichfinds widespread applications in the construction industryfor usage inceiling linings, flooring materials, electrical cables and roofing materials.Several fire requirements are put on these types of applications. For fire safety engineering and product developmen…
ABSTRACT With the growing number of therapeutic proteins on the market, effective delivery systems are receiving particular attention. In this study, biodegradable elastomers, intended for protein drug delivery and based on methacrylic tripoly(ε‐caprolactone‐co‐d,l‐lactide) cyclic ester with different ratios of ɛ‐capr…
The phase behavior of (PS-PIB)2-s-PAA miktoarm star terpolymers with varying volume fractions of PAA was investigated directly by transmission electron microscopy, atomic force microscopy, and small-angle X-ray scattering, and indirectly by thermogravimetric analysis and degree of water sorption. The microdomains of (…
We investigate nanocrystals of ternary compounds CdXHg1−XSe with 0<X<1 using a Raman scattering technique at room temperature. We obtained the correlation between nanocrystal (NC) chemical composition and the frequencies of CdSe-like LO and the HgSe-like TO and LO-modes. It is shown that the crystalline structure of t…
The magnetization change ΔM at the superconducting transition of LaIrSi3 has been measured in various magnetic fields H. The observed ΔM in H = 0 is within the range of the Meissner effect induced by the possible residual field, suggesting that the spontaneous magnetization, if it exists, is below the experimental acc…
This paper reports magnetic, magnetostrictive, and piezomagnetic experimental results performed on a pure iron and a Fe-B alloy, and associated modeling. Results allow a better understanding of the role of Fe2B phase in Fe-Al-B alloys.
Ferromagnetic electrodes covered with ultrathin carbon films are fabricated by chemical vapor deposition and rapid thermal annealing (RTA) to grow graphene and amorphous carbon on prepatterned Ni electrodes for testing their capacity to inject charges into a p‐type polymer semiconductor. Chemical and composition analy…
The goal of this research aimed to develop an accurate and reproducible textile-based optical fiber sensor for automotive seat occupancy. In our previous publication, the response of perfluorinated (PF) graded index (GI) polymer optical fibers (POFs) (62.5/750 and 62.5/490 μm) to bending and tensile loading was invest…
Polycrystalline tungsten samples were characterized and exposed to a pure H beam or mixed H/He beam containing 6% He in GLADIS at a surface temperature of 600 °C, 1000 °C, or 1500 °C. After 5400 s of exposure time with a heat flux of 10.5 MW m −2 , the total accumulated fluence of 2 × 10 25 m −2 was reached. Thereafte…
ZnO nanotapered arrays (NTAs) with successively modulated sharpness have been successfully demonstrated by a novel supersaturation-controlled hydrothermal method in zinc-NH3·H2O system. The filament-like, needle-like, sword-like, and pagoda-like ZnO NTAs with cone angle ranging from ~0°, 4.9 ± 1.5°, 20.4 ± 3.7° to 63.…
Large scale synchronous network-on-chip (NoC) requires complex clock tree design, which leads to a large area overhead and power consumption. Based on handshaking protocols, asynchronous NoC does not have global clock tree distribution, which results in a natural power saving mode without any explicit clock gating. Ho…
In the present work, the single crystal growth by solid-state crystal growth of (100−x)(K0.5Na0.5)NbO3–xSrTiO3, where x = 0,1,2,3 mol-%, has been examined in order to study the effect of SrTiO3 content on single crystal growth. Powders were prepared by the conventional mixed oxide method. <001> KTaO3 seed crystals wer…
