This lecture was formerly titled Lubricin: Alleviating the Effects of Dry Eye.
Abstract
Dry eye is an affliction where the tear film of the eye is unable to protect the cornea epithelium. One suspected cause of this condition is a deficiency of mucin, a protein that is thought to enhance wettability and reduce friction experienced during blinking. We report on the development of a model for mucin deficient dry eye and an investigation of the ability of lubricin, a heavily glycosylated protein, to restore lubricity and low friction during simulated blink events.

Professor Frank Gu discusses taking global solutions for sustainability from the lab into business. Conducting research and training of highly skilled researchers have long been a central focus of universities. A roadmap to bring knowledge created in an academic lab to a practical application can be a convoluted and challenging process. In this talk, Professor Gu will discuss the advantages of fostering industry partnerships, cultivating entrepreneurship, and creating business models and technology development roadmaps in bringing research solutions closer to commercialization.

Dr. Afsaneh Fazly, Research Director, Samsung Toronto AI Centre
Abstract: Wouldn’t we all love to seamlessly communicate and interact with our cell phones, smart watches, and even our home appliances? This is indeed the holy grail of AI: to build machines and systems that can think, behave, and communicate in a way that is indistinguishable from human intelligent behaviour (the Turing test). The AI community has long realized that effectively and truly passing the Turing test is extremely difficult, if not close to impossible. As such, for the past few decades, AI researchers have focused on solving fundamental problems in separate sub-fields of AI, such as computer vision, computational linguistics, machine learning, planning, and reasoning (to name a few). With the recent advances in these areas, we are finally at a point where we can bring the puzzle pieces of AI together to build wholistic multi-faceted and multi-modal systems that actually work in practise, hence the recent surge in industry investment and interest in AI. In this talk, I will first give a high-level overview of how AI research is key to the success of an innovative company such as Samsung. I will then go over some of our efforts at the Samsung AI Centre in Toronto around building multi-modal communication and understanding systems that will pave the way for next generation human–machine interaction.
Bio: Dr. Afsaneh Fazly is currently a Research Director at the Samsung Toronto AI Centre, leading a team of outstanding scientists and engineers on a variety of projects at the intersection of vision and language. Afsaneh has extensive experience in both academia and the industry, publishing award-winning papers, and building strong teams solving real-world problems. Her research draws on many subfields of AI, including Computational Linguistics, Cognitive Science, Computational Vision, and Machine Learning. She strongly believes that solving many of today’s real-world problems requires an interdisciplinary approach that can bridge the gap between machine intelligence and human cognition. Prior to joining Samsung Research, Afsaneh worked at several Canadian companies where she helped build and lead teams of scientists and engineers solving a diverse set of AI problems. Prior to that, she was a Research Scientist and Course Instructor at the University of Toronto, where she received her PhD from.

Title: “Alternative Lixiviants to Cyanide – The Thiosulphate Experience”
Hosted by Professor Vladimiros Papangelakis
Abstract
The use of cyanide in the recovery of precious metals, particularly gold, has been practiced for nearly 150 years, because of its efficiency, selectivity to gold and easiness to use. The major impetus in seeking alternative lixiviants to cyanide arises from the environmental hazards posed by the toxicity of cyanide, with numerous environmental groups throughout the world actively pursuing a ban on its use. On a few occasions, cyanide use is uneconomic due to certain characteristics of the gold ore, such as high content of organic carbon, copper, and sulphur.
Thiosulphate is currently considered the most attractive alternative to cyanide for leaching gold due to its low toxicity and its potential use on carbonaceous ores that cannot be readily treated by conventional cyanidation. This presentation reviews the development of the ammoniacal thiosulphate leaching process for gold and silver extraction and discusses the underlying leaching mechanism, thermodynamics, thiosulphate stability and gold recovery options. The chemistry of the ammonia-thiosulphate-copper system is complicated. However, we found that by maintaining suitable Eh and pH and by controlling the concentrations of thiosulphate, ammonia, copper and oxygen in the leach solution, high gold extraction can be achieved with low reagent consumption:
The thiosulphate technology was selected by Barrick Gold Corp. to process very refractory gold ores in Nevada, USA. In November 2014, the Goldstrike mine in Nevada poured its first gold bar produced using their patented thiosulphate leaching technology, with a technology team led by the presenter. This milestone marked the industrial beginning of a new process developed to extract gold from double refractory ores that could not be treated via the traditional cyanidation/carbon-in-leach (CIL). The arduous path of technology development and commercialization will also be discussed.

The Green Chemistry Initiative is hosting Dr. Pavani Cherukupally from Imperial College London as part of its online Seminar Series on Thursday, April 22 from 10-11 am. Dr. Cherukupally’s talk is titled: Sponges for wastewater reclamation, resource recovery, and infectious disease prevention.
Abstract: According to the United Nation’s Sustainable Development Goals 2030, there is a need for affordable, sustainable technologies to combat global water, environmental, and public health challenges. For example, the international oil industry produces over 100 billion liters of oil contaminated wastewater annually. The residual crude oil in these effluents is hazardous to the environment and valuable crude oil loss. On the other hand, antibiotic-resistant bacteria are estimated to cause 10 million deaths and $100 trillion in medical costs per year by 2050. In this talk, I will discuss a new sponge-based adsorption technology used to reclaim oily wastewater, reuse sponges, and recover residual crude oil from wastewater to improve circular economy metrics in the oil industry. Also, I will discuss sponges’ design for removing and killing bacteria in the water to provide safe water in medium- and low-income countries like Rwanda. Due to the excellent performance and cost-efficacy, the sponges could contribute to reforming water policies and accessible to people across the world.
