Anaerobic digestion is an environmentally-friendly process that breaks down biomass into simpler, more stable components, while simultaneously capturing energy in the form of a methane-rich biogas. Digesters are usually used to treat wastes, such as at municipal waste facilities, or from livestock farms. However, anaerobic digesters are not very reliable, suffering from occasional “digester upsets”. Consequently, anaerobic digestion is less attractive to industry as compared to other less environmental alternatives. The reason behind this unreliability lies in the complexities of anaero
The objectives of this proposed research are the development of a piezoelectric actuator system to assist nano machining by minimizing forces and the generation of nano-patterns to achieve the desired surface characteristics. The objectives shape the comprehensive technologies required to achieve flexibility, productivity and accuracy in manufacturing miniature systems through a judicious combination of experimental and analytical analysis.
Standing balance is controlled by several inputs, including vision, vestibular sense, and ankle proprioception Research studies in this field actively engage and manipulate these input mechanisms to examine their effects on the balance output, mainly muscle actuation in the lower limbs. While significant progress has been made, it is often difficult to isolate a single input and test its results on the output. The unique Robot for Interactive Sensor Engagement and Rehabilitation (RISER) has been developed in the UBC CARIS
In papermaking, a slurry of wood fibres, which are approximately 2 millimetres long and 30 microns in diameter, is drained through a forming fabric. In this drainage process the fibres get trapped by the fabric as the water drains through it. The actual drainage process is obviously highly complicated because the forming fabric geometry is complex, the wood fibres may interact with one another, and the wood fibres have variable properties. However, we may gain some understanding of dewatering by considering simplified versions of the process.
3D movies and videogames enjoy a rapidly increasing popularity. However, current display technology, especially for home theatres, still requires the viewers to wear assistive devices such as shutter glasses. We are developing 3D display technology that does not require such assistive devices. This technology uses micro-electromechanical elements and synchronized image content display.
There is an increasing demand for development of electric vehicle (EV) due to the serious energy shortages and environmental pollution. Advanced Lithium (Li) rechargeable batteries are the most promising power systems in commercial Hybrid EV. The main challenge is still the development of alternative material in terms of energy density, cycability, safety, and cost. In this proposed research, novel nanostructed material and catalysts will be developed to achieve these objectives for EV applications. This would help to make lithium batteries competitive with internal combustion engine.
The high throughput combinatorial testing for pharmaceutical applications requires fast methods for manipulating droplets in microfluidic systems. In this project, a microwave platform will be designed and employed for fast droplet heating, identification and detection. The use of extremely confined microwave energy makes heating, detecting, and identifying droplets possible. With the new platform it will be possible to control the temperature of each droplet separately.
