The Angular Propulsion Engine
BackgroundNumerous industry, such as but not limited to municipal solid waste management, and wastewater treatment generate a large number of waste gas streams. Carbon dioxide and methane are examples of waste gas generated from process steps including the combustion of fossil fuels and ethanol fermentation.Waste gas from these operations is flared,...

Biopsy Needle System to Prevent P. acnes Contamination
BackgroundInfections are a potentially devastating complication of any surgery. Amongst the most devastating are post-surgical joint infections caused by Propionibacterium acnes (P. acnes), now considered the major microbial cause of surgical implant failures. Without early diagnosis and intervention, these infections result in joint tissue necrosis...

Dual Purpose Upper and Lower Limb Rehabilitation Robot
BackgroundThere are 800,000 new cases of stroke in the United States and Canada each year. In cases of stroke, it is common for the upper and lower limbs to become weakened or paralyzed. Robotic rehabilitation systems have been developed to assist in the delivery of movement therapy to both the upper or lower extremities to maximize return of function...

Biological Nutrient Removal by Modified MBR System
Background:In response to increasingly stringent effluent nutrient criteria resulting from deteriorating surface water quality, biological nutrient removal (BNR) processes have become increasingly popular. In BNR processes, nitrogen and phosphorus can be removed simultaneously. These BNR processes employ a combination of anaerobic, anoxic and aerobic...

A Magneto-Rheological-Based Actuation System
Background:With current means of actuation, very few options exist that provide multiple degrees of freedom (DOF) and move independently without the addition of multiple motors. For instance, conventional means of safely actuating robotic devices involve the use of specially modified servo motors at each joint to control motion. In most applications...

A Magneto-Rheological-Based Clutch System for Robots
Background:The new frontier in the development of industrial automation lies in the area of small and medium enterprises where robots will be required to work in close proximity to human counterparts. Conventional means of safely actuating robotic devices involve the use of specially modified servo motors at each joint to control motion, in conjunction...

Sample Collection, Annotation, Archiving, Analysis and Distribution System (SCAAAD)
BackgroundCurrent data collection and archiving methods are time-consuming and error-prone. Field scientists and technicians must carry a wide variety of sampling devices that inherently lack the ability to communicate with each other - often relying on a pen-and-paper system of recording and annotation. Further, when they exit the field and return...

Formaldehyde-Free Phenolic Bio-Resins
BackgroundPhenol formaldehyde (PF) resins are synthetic polymers which have a market value of $10 billion globally per year. They are used in a wide variety of products, including coatings, adhesives, laminates, and engineered plastics. Comprising many household and industrial goods such as plywood, countertops, brake pads, and bearings. PF resins are...

Copper-based photovoltaic nanocrystals for thin-film solar cells
IntroductionIncreased environmental awareness promoted many countries to adopt renewable energy as the new power source. Solar energy tapped through photovoltaic (PV) technology has become the widely accepted source of power generation, as it operation generates no pollution, and no greenhouse gas emissions. Improving efficiency while reducing cost...
