Temperature measurement of nanoparticles (NPs) under heating is an important technique in order to achieve potential applications such as photothermal cancer therapy and nanofabrication. We implemented the method to estimate the local temperature of a laser-heated gold NP on glass substrate in various surrounding media by applying the light scattering spectroscopy. We discuss experimental results ...

Even though sonochemical reactors have been studied extensively for decades, there is limited data on their characterization when the volume of the sample is fixed. The Acoustics Module and COMSOL Multiphysics® software are used to resolve the pressure field. The validated numerical model will be used to compare different configurations; changing the Height (H), diameter (D) of the reactor and ...

Electroporation is an increase of the cell membrane permeability due to the formation of aqueous pores in it when the cell is under the influence of an intense electric field . The formation of such pores in the membrane can be used to enhance the uptake of chemotherapeutic drugs into the cell in a cancer treatment known as electrochemotherapy . In some cases the direct experimental ...

Introduction: Flexures are low-cost bearings that are capable of providing motion guidance with high repeatability and low friction (Figure 1). However, applications of flexure bearings are often limited by their low range. This is because motion guidance in flexures is provided by bending/flexing of members; thus, range is limited by the bending stiffness. As the bending stiffness can be ...

Introduction Electromagnetic stimulation is a common therapy to support bone healing in cases of avascular necrosis or pseudarthrosis. An electrostimulative screw implant (Asnis III s-series screw in Figure 1) is used to stimulate bone regeneration in the treatment of femoral head avascular necrosis. To enable positive outcome of the treatment, optimal positioning of the electric implant is ...

Solders are typically used to join similar or dissimilar metals, referred to as substrates. In some cases solders are also used to join completely different classes of materials. For example, a joint between copper busbar and silicon solar cell represents a set of dissimilar substrates. In the formation of a solder-substrate couple, the system must have been subjected to at least a single ...

Pumping liquids at small scales is challenging because of the principle of reversibility: in a viscous regime, the flow streamlines through a fixed geometry are the same regardless of flow direction. Recently we developed a class of microfluidic pump designs based on tilted flexible structures that combines the concepts of cilia (flexible elastic elements) and rectifiers (e.g., Tesla pump). We ...

COMSOL Multiphysics® software has been used in computational geodynamics for years. Because very high pressure in the mantle even significantly compressed the mantle up to ~40%, it is crucial to consider the mantle compressibility in computational geodynamics. COMSOL Multiphysics allows consideration of mantle compressibility using the CFD Module and I benchmarked COMSOL Multiphysics using ...

Polymer sheets are widely used for glazing and roofing structural applications. The primary design requirements of these polymeric sheets are to resist uniformly distributed wind loading. Conventional building materials such as steel and glass plates are relative stiffer compared to polymeric sheets. The deflection of high stiff plates is about an order lower than polymeric plates. Polymeric ...
