Preparing Asphaltene-based Carbon Fibres by Electrospinning for Optoelectronic Applications

Currently, most electrodes used for optoelectronic application are coated with metal oxides as a conductive substrate, but are expensive to produce. There have been many studies on finding a cheaper and flexible alternatives such as graphene. Asphaltenes are polyaromatic hydrocarbons defines by their solubility class that has a similar structure to graphene. Asphaltenes are found in crude oil, tar sands and coal, but create several problems in the oil industry and are considered a waste due to its tendency to aggregate.

Artificial Intelligence and Machine Learning in the Interpretation of Wide-Complex Tachyarrhythmia

Wide-Complex Tachyarrhythmia (WCT) is an abnormality in which the heart rate is elevated and QRS complex duration is increased. An electrocardiogram (ECG) is a simple and quick test used to review heart functioning, so ECG images can be used to determine whether a patient is having an abnormal heart rhythm such as WCT. A WCT diagnosis based on the ECG can be difficult as it can take a lot of time and considerable expertise to make an accurate interpretation.

Organic cathode materials for alkali-ion batteries

Clean renewal energy sources, such as hydro, wind, and solar energies, have been receiving increasing demands for sustainable societal developments. Due to their intermittent nature, rechargeable batteries are required for the storage of these renewal energy sources. Current rechargeable batteries constructed with conventional inorganic cathode materials have restricted energy densities, along with sustainability issues.

Synthesis of CO2-Based Polymers for Carbon Capture - Phase II

Carbon dioxide is produced from the combustion of fossil fuels and as a by-product of many chemical processes. The increasing concentration of CO2 in the atmosphere has now been decisively linked to global climate change. The use CO2 as a carbon-building block has attracted much attention due to its low cost, ease availability, and its potential to substitute fossil fuel-based feedstocks, in addition to the clear positive environmental effect of removing it from the atmosphere.

Non-Invasive Real-time Glucose-Monitoring Smart Textiles

You may have heard of monitoring heart rate in a smartphone using lasers for measurement. Now think of having the wristband or some other wearable gadget and your health status is monitored in your smartphone or your doctors' cloud. Glucose is one of these parameters that can be measured by this wearable device but the challenge is measuring the concentration of glucose in sweat which is almost 1000 times lower than the glucose in the blood. Our group could measure these ultra-low levels of glucose in synthetized sweat.

From pipeline inspection data to insight

To ensure oil and gas pipelines operate safely, instrumented inspections and assessments are completed on a recurring frequency. A common and valuable inspection method is In-line inspection (ILI). This form of inspection uses a measurement device (ILI tool) that is propelled through the pipeline by product flow and the tool identifies and sizes anomalous conditions along the inside and outside walls of the pipeline that could affect the pipes ability to contain the product.

State-of-the-art Battery Cycle Life Extension

The ever-growing demand for energy storage, especially with high density and low-cost, has both academia and industry research communities working hard to develop and optimize energy storage technologies. Among the top energy storage technologies are Lithium metal batteries (LMBs) which have an exceptionally high specific capacity (3860 mA h g?1) in comparison to that of the conventional graphite-based LiC6 batteries (372 mA h g?1).

Microstructure Evolution and Thermomechanical Fatigue of Service-Exposed Coke Drum Materials

There is a growing demand when it comes to the repairing of the coke drum since most of the current in-use coke drums has been in service for decades. This study will develop a new methodology to assess the microstructure evolution and thermal mechanical properties of service-exposed coke drums. The focus of experiments of this project involves high temperature fatigue test to evaluate the fatigue life of the material. Through the studying, the evolution of microstructure evolution will be better identified and understood, providing the foundation of the analysis in the future.

Biphasic CO2 extraction/stripping of bioactive compounds from fermentation overlays

Recent studies have shown that cannabinoids can control chronic pain and muscle spasms as well as other diseases related to chemotherapy, AIDS and epilepsy, therefore it is very important to investigate about cannabinoids. However, it is very difficult to strip it out cheaply from the triglyceride oil while securing high purity and high concentration level; and this challenge may limit its use for medical purposes. The proposed solution to tackle the problem is to develop a liquid (CO2)-liquid or (scCO2)-liquid extraction process using unique counter-current extraction column.

Bioprocessing strategies for enhanced production of heme in Escherichia coli

Ardra Inc. has sustainably produced many high-purity chemicals that are used for various flavor, perfume, and cosmetic applications. Combining industrial/business expertise provided by Ardra with academic/research skills provided by Dr. C. Perry Chou’s lab, we are aiming to effectively produce high-value heme compound using engineered E. coli host organism. Major efforts will be dedicated toward engineering of this bacterium by adopting synthetic biology, metabolic engineering, and bioprocessing strategies to facilitate large-scale bio-based production of heme.
