Dye sensitized solar cells (DSSCs) have received tremendous attention as alternative photon harvesting devices. While the sintered TiO2 nanoparticle network attached with dye molecules achieves efficient photon absorption, the electrons have to diffuse through the long TiO2 network to ... En savoir plus

The production of polymer fibers is done by drawing raw material (preform) in a vertical cylindrical furnace whose heated walls radiantly heat the preform. The wall temperatures are very high and the dominant heat transfer to the fiber is by radiation with little effect from the ... En savoir plus

Partial differential equations (PDEs) govern many phenomena in nature. Solving optimization problems which comprises the solution of large number of PDEs, is expensive concerning time and memory. Therefore, to reduce the solution cost, original problem is transformed to a corresponding ... En savoir plus

The swelling behavior of human intervertebral disc is strongly influenced by chemical changes in the surrounding environment. Swelling of IVD is governed by various physical phenomena, including chemical and electric potential based transport, electrical charge balance, and swelling due ... En savoir plus

In a nuclear reactor, the containment is the last barrier for the release of radioactivity during severe accident conditions. Containment material can be concrete or steel or steel-lined concrete. Steel containments have a high load bearing capacity and a high degree of leak tightness at ... En savoir plus

Flow measurement of molten metals is a formidable task considering the hostile conditions. Many electromagnetic methods have been evolved for measurement of flow of conductive medium. The Lorenz force velocimetry is promising considering its non-intrusive nature. The Lorenz force ... En savoir plus

An artificial hand is the one that replaces the hand lost through trauma, disease, or congenital conditions. The proposed design is to simulate a sensor, used in prosthetic hand so as to measure the pressure required to hold the object, using COMSOL Multiphysics®. The physical parameters ... En savoir plus

Despite of the existing successful clinical applications, however, the interaction, i.e. artificial sensing, between the robot and the patient is still very limited. With the help of various cameras, vision is almost the only feeling that a robot can have. In order to imitate the human ... En savoir plus
