|A study of flow behavior in the absence of gravity! - November 2nd, 2016|
Microgravity environment offers a unique opportunity to study flow behavior in the absence of gravity. Different experiments were designed by Dr. Ziad Saghir and conducted on board the Space Shuttle, Unmanned FOTON satellite and recently on board the International Space Station by Canadian astronaut Bob Thirsk (pictured). At this event Dr. Saghir, will provide a discussion of his exceptional 14 years of experience conducting research on board different space vehicles.
In particular, he will discuss his recent efforts in the field of oil recovery. An accurate simulation of the various forms of mass flux is an important part of oil exploration and optimal oil recovery. The diffusion and thermodiffusion coefficients of binary hydrocarbon mixtures have been measured and analyzed in detail elsewhere, as one step forward. He measured the separation in a ternary hydrocarbon mixture of tetrahydronaphthalene, isobutylbenzene, and dodecane at five different compositions due to thermal gradients, and determined the Soret and diffusion coefficients of this mixture. The thermodiffusion experiment was conducted by means of a Mach-Zehnder Interferometer (MZI) using two wavelengths and in a low gravity environment on board the International Space Station (ISS).

|A historical perspective on the evolution of high-temperature materials and processing technologies for aircraft engines - October 19th, 2016|
"Over his existence man has developed equipment to satisfy his needs." – Chester T. Sims, General Electric Company.
Modern aircraft engines present some of the most challenging working environments for metallic materials – the temperature of combustion gas entering the turbine exceeds the melting point of the white hot rotating blade alloy!
From the conception of high-temperature materials based on austenitic stainless steels in the 1930s to the latest generation of single crystal Ni-base superalloys used in Rolls-Royce Trent 1000 engines, we have come a long way as metallurgists to understand the science and master the art of crafting some of the best-behaved materials in the engineering field. In this talk Dr. Linruo Zhao will walk the audience through a historical journey of significant discoveries through the decades such as:
All these discoveries and historical milestones have contributed to the engineers being able to design gas turbines that can function at faster speeds, at higher temperatures, more efficiently with extended service lifetimes. Understanding the past is incredibly important when understanding where to push science forward in the future!

|Additive Manufacturing (3D Printing) vs. Forging - May 4th, 2016|
Is direct digital manufacturing a threat to forging? That is the question this presentation will explore.
Over the past decade many direct digital manufacturing or additive manufacturing technologies have been investigated with some being technically and commercially viable to make a shape. This presentation will identify the known current direct digital manufacturing technologies which compete with forging part manufacture and forging die manufacture.
The presentation will identify the activities surrounding this technical community. For instance the ASTM F-42 Committee was recently formed to standardize additive manufacturing technology with its first standard, ASTM F2792-10. Several Additive Manufacturing (AM) technologies are available to produce metal parts. Whether or not these parts will compete with forgings remains to be seen. As fit-check prototypes, perhaps yes; as fatigue resistant, fracture tolerant parts, perhaps no.
It is advised that the forging industry continue to monitor AM sector to keep pace with these evolutionary or even revolutionary advances.

|'Smart' Nanomaterials for Cancer Therapy - March 2nd, 2016|
Materials science contributes to cancer treatment breakthroughs! Recent developments in nanotechnology has provided new tools for cancer therapy and diagnosis: gold nanoparticles are being used as radiation dose enhancers and anticancer drug carriers in cancer therapy.
Dr. Chithrani and her team has shown for the first time that cancer drug loaded gold nanoparticles can reach the nucleus (i.e. the brain and most desirable target in cancer therapy) of cancer cells to enhance the therapeutic effect dramatically.
In chemotherapy, smart delivery of highly toxic anticancer drugs through packaging using nanoparticles will reduce the side effects and improve the quality and care of cancer patients.
Recent advancement in nanomaterial characterization techniques will facilitate mapping of nanomaterial distribution within biological specimens to correlate the radiobiological effects due to treatment. Fate of gold nanoparticles within biological tissues can be probed using techniques such as TEM (transmission electron microscopy) and SEM (Scanning Electron Microscopy) due to their high electron density.
Gold nanoparticle mediated combined chemoradiation would provide promising tools to achieve personalized and tailored cancer treatments in the near future.
Join us on March 2nd for the latest news on the role materials science is playing in cancer research!

|Forensic engineering vs. failure analysis - What is the difference?|
The forensic engineering analysis of product failures has matured significantly over the past two decades in Canada. Recently, PEO became the first Canadian regulator to undertake development of guidelines and best practices for the professional practice of forensic engineering in a consistent, unbiased and ethical manner.
‘Forensic engineering’ is primarily concerned with determination of cause and assisting with the determination of (i) liability and (ii) award of damages in litigation cases. ‘Failure analysis’ will be categorized as a subset of forensic engineering practice. Accordingly, clear establishment of scope, objectives and costs of an investigation with potential clients is paramount for advancing the practice and will be discussed.
In any case, a comprehensive product failure investigation necessitates the identification and analysis of all relevant contributing factors. Accordingly, the forensic engineer is usually faced with the task of having to rank or eliminate contributing factors to determine causality. Using a few instructive case studies, this presentation will demonstrate procedures on how contributing factors in a product failure analysis investigation can be quantified to assist the client with determination of liability in an unbiased manner.

|Quality Assurance Activities for Corrosion Resistant Membranes in Pressure Vessels
Apr 1st, 2015
The operating conditions of several process vessels in the hydrometallurgical sector are so severe that engineers employ carbon steel with corrosion-resistant cladding such as titanium, zirconium and tantalum; high nickel alloy weld overlay; or the use of corrosion resistant membranes. Corrosion resistant membranes may be constructed of halogenated synthetic rubbers, vinyl ester resins, fluoropolymers, bituminous mastic, or homogeneously bonded lead.
The quality and integrity of such membranes is of the utmost importance to the safe operation and 20+ years of service life for such vessels. A number of these membranes have been working in acid leach reactors, pressure oxidation autoclaves, hydrogen sulphide (H2S) precipitation reactors, pressure letdown vessels, and off-gas cyclones.
Murray Pearson will review the quality control activities undertaken for several recently completed and on-going hydrometallurgical projects, including pre-qualification, validation testing, material verification, contamination control, discontinuity (holiday) testing, non-destructive examination and assisted/enhanced visual inspection.
While it is not possible to cover all of the quality control activities associated with the installation of corrosion resistant membranes mentioned, some of the important performance-based quality control criteria and standard methods for evaluating membrane installation prior to putting it into actual service will be highlighted.

|Biomaterials – Where Are We Now and Where Are We Heading?
- Jan 14th, 2015
Society has spent centuries preventing iron corrosion, making aluminum more malleable and casting brass without cracking. These three structural materials have advanced society more so than anyone studying these materials in their infancy could have ever predicted. The time has come now to add another material to that list. The next structural material that needs to be studied is calcium phosphate.
It sounds strange, however when you take the time to pause and think, calcium phosphate is more important to us than steel, aluminum and brass combined. Calcium phosphate is the material that composes human bone and acts as the structural material for our bodies.
We all, at least vaguely, understand the advances in structural materials which exist outside of the body, however how much do we really understand about the structural materials that reside within our body? And what do we do when those structures fail? With our aging society and increasing desire to live longer, fuller lives, the next societal revolution is coming from biomaterials and our ability to make replacements that integrate better, and last longer. New manufacturing technologies and advanced characterization techniques are opening up new possibilities for the bionic man of the 21st century.
If you’re wondering what we have done as a society with biomaterials, and where we are heading, you will not want to miss Dr. Kathryn Grandfield’s discussion on the topic.
Kathryn Grandfield - Assistant Professor Materials Science and Engineering
