Miniaturized enzymatic biofuel cells (EBFCs) converting biological energy into electrical energy by using enzyme-modified electrodes are considered as a candidate to power implantable medical devices and portable electronics. In this study, modeling of the EBFC system has been conducted using finite element analysis b…

The fabrication of functional hybrid materials that preserves and combines the properties of their building blocks is a central issue of nanosciences. Among the different classes of nanomaterials, carbon nanotubes are promising for electronics, catalysis and composite applications. Within the context of sustainable de…
Luminescent silicon nanoparticles, apart from their potential use in optoelectronics or photovoltaics, are also very promising for biological applications, as fluorescent labels, biological sensors, drug-delivery systems or scaffolds for various tissues. Aqueous or isotonic colloidal solutions of stable, nontoxic and…
The following topics are dealt with: automotive electronics; SiP; microwave devices; substrate and interposers; optoelectronics devices; edge devices; BEOL; printed electronics; thermal management; integrated circuit interconnection; advanced packaging; 3DIC packaging; and power electronics integration.
Ceramic particles with high hardness and thermal stability can be used to fabricate in situ carbide particulate-reinforced iron-matrix surface composites with high macro-hardness while retaining high toughness. This paper describes a general process by which in situ carbide particulate-reinforced iron-matrix surface c…
Significance and Use 3.1 The gaskets covered by this practice can be used on, but are not limited to, equipment constructed of the following materials: (a) stoneware, (b) glass and glass-lined, (c) tantalum (solid and lined), (d) titanium (solid and lined
All papers published in this volume of IOP Conference Series: Materials Science and Engineering have been peer reviewed through processes administered by the proceedings Editors. Reviews were conducted by expert referees to the professional and scientific standards expected of a proceedings journal published by IOP Pu…
Recent developments in vertical integration schemes such as 3D-NAND have introduced a significant need for fast oxide slurries. Balancing low defectivity and high planarization with extremely large bulk oxide removals is crucial. Ceria-based slurries with fine-tuned chemistries are well suited to meet these demands. M…
In order to clarify the effect of water adsorption on fuel cell cathode catalysis surface, we have investigated electronic structure of Pt and Pt-Co nano-particles with O2 adsorption and O2/H2O co-adsorption by in situ XAFS and in situ hard X-ray photoelectron spectroscopy (HAXPES). First, the electronic structure cha…
The present work clarifi es the infl uence of the cleanliness and the micro hardness on the machinability differentiation of carburising steel grades with different contents of sulfur.Future work will report on the infl uence of grain size by using SEM-EBSD on the machinability of the same steels.Further details can b…
Low cost and high durability are considered as the main challenges in mass scale commercialization of the low temperature fuel cells. Anion exchange membrane fuel cells (AEMFC’s) have attracted tremendous attention because of their promising characteristics to overcome some of the critical problems associated with pro…
Finding low cost methods of storing renewable power is a key obstacle facing wider use of solar and wind technologies. Creation of combined solar cells and batteries or supercapacitors has recently received attention, but thus far energy densities have been low. In this work the highest volumetric and areal energy den…
Cover Caption: The present work clarifies the influence of the cleanliness and the micro hardness on the machinability differentiation of carburising steel grades with different contents of sulfur. Future work will report on the influence of grain size by using SEM-EBSD on the machinability of the same steels. Further…
Significant effort has gone into developing novel metal precursors for Atomic Layer Deposition (ALD). This effort has been primarily driven by the industry need for new high K materials and metals films. The need for novel oxidants and sources of nitrogen has been largely ignored. This paper focuses on delivery of anh…
Oxidation is a key process step in semiconductor device fabrication. Oxides are widely used in the production process as gate dielectrics, interfacial layers for high-k deposition, pad oxides, sacrificial oxides, screen oxides, protection oxides etc. Even though the used oxide thicknesses become thinner the thermal bu…
Struktol has launched novel processing additive Struktol® HT 750, the first in a new series of additives for diamine crosslinked polymers such as ethylene acrylate (AEM) and polyacrylate (ACM) elastomers and hydrogenated nitrile rubber (HNBR). Such polymers are a challenge because their physical properties are often c…
The economy of concrete made it historically one of the most preferred construction materials for the establishment of our modern infrastructural system (Aïtcin 2000). However, normal concrete presents deficiencies like the low strength developed in comparison to the weight and the brittleness. Among the achievements…
The present paper is concerned with the mechanism of cavitation erosion. A theoretical model for the formation of a single pit produced by a microjet produced by a collapsing cavitation bubble is presented and the model developed to give the average surface slope of the eroded surface as a function of fluid velocity a…
Thermal expansion mismatch among the materials used in a Solid Oxide Cell (SOC) generates in-plane strain within the SOC layers during the cooling process following sintering. These residual stresses induce cell curvature for asymmetric cells, challenging the stacking process, but more importantly they may also result…
