Processing and Mechanical Characterization of Compression-Molded Ultrahigh Molecular Weight Polyethylene Biocomposite Reinforced with Aluminum Oxide
Abstract: Ultrahigh molecular weight polyethylene (UHMWPE) has been widely used as a bone implant material in orthopedic surgical applications in trauma due to its low coefficient of friction, good biocompatibility, and excellent wear and corrosion resistance properties in comparison to other polyolefins. But, due to the formation of wear debris, implants loosen and fail after 12–15 years of implantation. In order to enhance lifespan, the role of alumina (Al2O3) reinforcement on …

Thermo-physical Properties of Asphalt Predicted using Molecular Dynamics Simulation
Abstract: This study is an essential step to get thermo-physical properties of asphalt using molecular dynamics simulation. It deals with the validity of dreiding force field for asphalt binder model. Both all atom and united atom models of asphalt are considered in my study to find the better model for MD simulation applying dreiding force field potential function. The potential energy values at different time steps are compared to get the …

Synthesis, Characterization and Photocatalytic Activity of Bismuth Doped Titanium Dioxide under Different Light Sources
Abstract: 800x600 Photocatalysis is a recognized approach where light energy is employed to excite the semiconductor material and produce electron-hole pairs. These electron-hole pairs eventually involves in the detoxification of pollutants (in air or water) & water splitting. TiO2 photocatalyst shows poor activity in visible light due to its wide band gap (3.2 eV), which restricts its use under Sun light. In the present work, photocatalytic activity of TiO2 was enhanced …

Developing Molybdenum Doped Zinc Oxide Nanoparticles’ Sensors for Quality Assessment of Black Tea
Abstract: Zinc oxide is a well-established sensor material for detection of various organic molecules. In a quest of developing a sensor array for quality assessment of black tea, developing pure and molybdenum doped nanocrystalline ZnO-based sensors. The effect of changing the sintering duration and time has been studied. FESEM, EDS and XRD characterisations confirmed the formation of wurzite nanocrystals of approximately 20 nm. The 2% molybdenum doped ZnO (calcined at 500 …

Design of Feedback Loop for Ultra-sensitive Nano-g Resolution MEMS Tunneling Accelerometer
Abstract: The tunneling accelerometer often used for attitude control of micro and nano satellite can be operated both in open loop circuit as well as close loop circuit. Closed-loop operation improves the overall sensor linearity, dynamic range, and bandwidth. The interface circuitry in a closed-loop device reads the sensor signal and uses feedback to maintain the proof mass in a null position in a stable manner. In this paper we present …
