Surface plasmon resonance in metallic nanoparticles is highly and shape dependent, which enables varius applications in photovoltaics, photonics, sensing and even medicine. Particularly we observe redshift in plasmon resonance with increasing nanoparticle size. We investigate nanoparticle size influence on plasmon resonance within theoretical and numerical approach and compare results with ...

In the core of Chemical Engineering is the reactor design that includes most of all scientific disciplines. The reactors, in general, are treated ideally. Unfortunately, it is observed in the real world a very different behavior from that expected. Thus, to characterize nonideal reactors is used, among others, residence time distribution function E(t). The aim of this present work is to ...

Cooling of high-power density electronic devices remains a challenge. Microfluidic heat-pipes with the potential of achieving ultra-high thermal conductivities offer a low-cost technology for cooling electronics. To achieve high thermal conductivity, it is critical to maximize the rate of liquid transport inside the heat pipe. We propose a novel array of microfabricated pillars to maximize liquid ...
Henrik Steepler earned his PhD in Computer Science in 1999 at Chalmers University, Sweden. Since 2003, he has been working at Microsoft on emerging markets like Security, Virtualization, and since 2007 on their High Performance Computing (HPC) initiative. He is now managing the partner network for Microsoft in Europe, the Middle East, and Africa around HPC.

The performance of biofilters relies on the presence of a sufficient amount of water in the biofilter material. And breakdown of filtration performance is often caused by inappropriate water content. The present study focuses on the drying dynamics within such filter, which are modelled as wetted porous media. Analyzing gas flow and water content we find that such systems exhibit instable ...

A 3D electro-conjugate heat transfer model was made to study an embedded microfluidic/TEG system (μF/TEG) system. An innovative embedded microfluidic/TEG system (μF/TEG) system is proposed which enables a device to be able to provide power to its cooling system eliminating external power input and resulting in energy efficient and more reliable heat removal system. The research identifies ...

Steam generators (SGs) are used in CANDU® nuclear reactors as heat exchangers to convert water into steam using heat generated in the reactor core. Ferrous trefoil broach support structures prevent excessive vibration of thousands of SG tubes. A probe that uses pulsed eddy current (PEC) technology has been designed for inspection of support structures, from within SG tubes, to detect and ...

Metal reed valves are used for flow rectification in electrohydraulic pumps driven by smart materials at high frequencies but it is difficult to predict their behavior when the surrounding fluid has considerable inertia and viscosity. Simulation of this phenomenon involves modeling the fluid-structure-interaction between the bending of the reed and the flow past the valve. In this model, we use ...

The rapid development of electronic devices leads to more demand for efficient cooling techniques. Porous media represent a convincing passive cooling enhancer due to its large contact surface area to volume ratio and intense mixing of ﬂuid ﬂow. In the present work, numerical studies have been investigated to study the heat transfer characteristics of aluminum porous metal foam subjected to ...

A computer controlled microwave exposure system and specialized applicators were constructed for the purpose of facilitating accurate observations of microwave radiation effects on uninfected and infected biological tissue in vitro and in vivo under different electromagnetic modalities and exposure configuration. To address diverse requirements, three different applicators were developed: a ...
