Molecular Dynamics Simulation Study on Nanoelectromechanical Oscillator based on Graphene Nanoflake
Recently graphene has also been highlighted as an ideal lubricant for microelectromechanical systems (MEMSs) and nanoelectromechanical systems (NEMSs), where ‘traditional’ lubricants no longer function normally. Atomic-scale graphene can be fabricated using micro- mechanical chop crack, [...]
Analysis of Gate-Length Dependence of Lags and Current Collapse in Field-Plate AlGaN/GaN HEMTs
We make 2-D transient simulations of field-plate AlGaN/GaN HEMTs with a semi-insulating buffer layer, where a deep acceptor above the midgap is considered. We particularly study how the gate lag, drain lag and current collapse [...]
Analysis of Breakdown Characteristics in Field-Plate AlGaN/GaN HEMTs: Dependence on Deep-Acceptor Density in Buffer Layer
We make a two-dimensional analysis of field-plate AlGaN/GaN HEMTs with a Fe-doped semi-insulating buffer layer, and studied how the deep-acceptor density in the buffer layer NDA and the field-plate length LFP affect the breakdown voltage [...]
Analysis of Breakdown Voltage of AlGaN/GaN HEMTs with High-k Passivation Layer and High Acceptor Density in Buffer Layer
AlGaN/GaN HEMTs are now receiving great interest for application to high-power microwave devices and high power switching devices. To improve the breakdown voltage, the introduction of field plate is shown to be effective, but it [...]
Tension prediction using web moving speed and natural vibration frequency
The characterization of web dynamics is critical for web handling and process control of roll-to-roll (R2R) manufacturing systems. One such critical characterization parameter is the tension in a moving web, which ultimately determines the efficacy [...]
Robot Axis Control Using a Differential Learning Algorithm
The motion control of robotic arms using brushless DC motors has been implemented using various mechanisms, including a model predictive controller (MPC), a fuzzy controller and supervised machine learning methods. In order to provide a [...]
Synthesis of polyaniline catalyzed by soybean peroxidase immobilized in halloysite nanotubes
Alvarado-Canché C., López-Martínez J., Romero-García J., Ledezma-Pérez A., De León-Santillán A., Gallardo-Vega C., Centro de Investigación en Química Aplicada, MX
Polyaniline is one of the most extended studied conducting polymer because of its simple synthesis, low cost, high conductivity and excellent environmental stability. Synthesis of this inherently conducting polymer can be carried by several methods, [...]
PVA cryogels obtained by biomimetic synthesis of polyaniline using hematin supported on halloysite nanotubes as catalyst
Jiménez-Cárdenas P., De León-Santillán A., Gallardo-Vega C., Centro de Investigación en Química Aplicada, MX
We studied the biomimetic synthesis of polyaniline as an alternate route to prepare electrical conductive cryogels (ECC), unique structures that combine intrinsic conductivity and hydrogel properties. For that purpose, hematin a natural porphyrin with peroxidase-like [...]
A Learning-based Approach to Cover Short-term Camera Failure in a Monocular Visual Inertial Odometry System
Localization and navigation have multiple established methods in sensing and fusion algorithm. Previous studies use different sensors such as Global Navigation Satellite System (GNSS) and Global Inertial Navigation System (GINS) using GPS and an inertial [...]
