Junior Engineering Science

Week 1 July 8–12 Week 2 July 15–19 Week 3 July 22–26
Pharmaceutical Engineering: Designing Drug Delivery Automotive Engineering Solar Energy: Materials & Cells

Engineering science is an intensive area of study that encompasses a broad range of sciences, mathematics, engineering sciences and design. The Junior Engineering Science stream is designed for students who have a definite interest in engineering and science and want to know more about the theoretical knowledge that builds engineering practice. This course stream is designed to give participants a better understanding of the theory behind some of the most important aspects of engineering. This year’s junior courses will investigate concepts in automotive engineering, pharmaceutical science and solar energy. You will explore engineering fundamentals and theoretical science in hands-on experiments that solve real-world problems.

J-ENG SCI-1 | Pharmaceutical Engineering: Designing Drug Delivery

Week 1 (8–12 July 2013)

That pill you just took for your headache contains 325 milligrams of acetaminophen, yet it weights 3.5 grams. What are its other ingredients and what role do they play? By making and testing commonly used drug delivery systems, this course will investigate the importance of the “non-medicinal ingredient.” Molecular and cellular concepts from chemistry and biology will be integrated to illustrate how engineers can make small changes to formulations to alter the effectiveness of a medication. The latest innovations in pharmaceutical science will also be used to highlight the collaborative effort of scientists and engineers in improving medicine around the globe.

Instructor: Lynda Mao

J-ENG SCI-2 | Automotive Engineering

Week 2 (15–19 July 2013)

The modern mass-produced vehicle is bursting at its seams with advanced technology. Many common features found in ordinary cars today were initially developed for competition race cars. This course aims to strip these vehicles to their bare components and illustrate how their systems work together. We will examine the internal combustion engine from the inside out. Through consideration of pressure dynamics, students will learn how power is generated. By dissecting the components of a car’s chassis, students will develop an understanding of how power travels from the engine to the wheels. We will examine physical concepts such as torque and friction. We will also consider handling characteristics in terms of braking and suspension systems. Finally, participants will learn about single- and multi-vehicle aerodynamics, as well as optimal driving patterns on the track. Students will employ their understanding to build working models of various components of the powertrain, culminating in the construction of a radio-controlled car.

J-ENG SCI-3 | Solar Energy Materials and Cells

Week 3 (22–26 July 2013)

Electricity has been central to the growth and prosperity of human societies. However, the human population is expanding: by the year 2050, projections indicate there will be 9 billion people on the planet. How will we meet the electricity needs of these people? Solar energy has long been regarded as an ideal form of alternative energy. Currently, only 0.4% of land is required to meet today’s need for electricity. In this course, students will learn about the fundamentals of solar cells, including semiconductor devices, introductory quantum mechanics and solar cell operation. Next generation technologies such as thin-film, quantum-dot and organic solar cells will be discussed. Practical aspects include a mini-solar car challenge and construction of blueberry nanocrystalline titanium dioxide solar cells. Students will also tour the Kortright Center for Conservation, BlueSky Solar Racing (U of T’s solar car team) and the Advanced Photovoltaics & Devices Lab. The course will incorporate the latest information on novel third-generation solar cell technologies and state-of-the-art characterization equipment. It will also feature a comparative analysis of different electricity generation sources including solar, wind, geothermal, nuclear, hydro and coal to allow students to think critically about the environmental and cost implications of different electricity generation sources.
