Background Hi! My name is Caitlin, I’m one of the mechanical leads for the junior Chem-E Car (CEC) team. I’m also the president of UBC Dance Horizons, part of a dance team, and helping to plan a case competition for the Oil and Gas initiative, on top of taking 7 courses. A question I get a lot is “How are you not dying?”. So here is my take on how to do all the things you love and not die.
Chem-E-Car’s New Fuel Cell Division While the chemical team is building clocks and electrical team is making a new stopping mechanism, the fuel cell team is here to ensure that the car has the power to move! This year, UBC Chem-E-Car’s Junior Battery team has expanded to incorporate a new fuel cell division. Several universities have had overwhelming success using fuel cells in their cars, and we’re hoping to cash in on this as well.
Open positions: We are looking for enthusiastic UBC students to help with the team’s finances and sponsorship activities. Email us and let’s chat! firstname.lastname@example.org Backstory Last summer, we received an interesting e-mail from the UofT Chem-E-Car team. They’ve just officially launched as a design team and wanted to know more about our team’s financial structure. Here’s what we shared with them. Department Funding We maintain a very close and important relationship with UBC’s Chemical & Biological Engineering department.
Introduction In the “Chem-E-Car Reaction Mechanism” article, Jayg and Josh talk about the iodine clock reaction and how a light-dependent resistor (LDR) is part of the stopping mechanism. The LDR changes electrical resistance depending on how much light is hitting it; as light intensity increases, resistance drops, and vice versa. Theoretically, if we shone light on an LDR in an iodine solution as its colour went dark, light intensity as measured at the LDR’s surface would fall.
*Disclaimer: What’s brewing, figuratively, not literally. The lab is not food safe, NO FOOD OR DRINKS IN THE LAB! Introduction As you may have read in part one, our team is working on an app to automate the brewing of craft beer. To understand the homebrewing process we made a batch of Pacific ESB, an ale that is light with a crisp bitter aftertaste. We made a few mistakes throughout the process (BURNT GRAINS) but learned from those mistakes to make the second batch better.
Reflections 2016 has been a very exciting year for the Chem-E-Car team. We have presented our work in more than 7 conferences, with topics ranging from the clean energy industry (Generate 2016) to chemical engineering innovation (CHBE Engineering Research Day). From these events, we have won 5 different awards. Notably, we placed 1st among 41 teams from all over the world for our poster presentation at the American Institute of Chemical Engineers (AIChE) 2016 Student Conference in San Francisco.
Introduction The Iodine Clock reaction is the official stopping mechanism for the 2016-2017 Junior Chem-E-Car design team. The reaction involves a color change with an Iodine indicator to signal the stopping mechanism, via a light dependent resistor. Through calibration, the reaction time can be determined by the ratio of Potassium Iodide and Sodium Thiosulfate. The correlation between time and ratio is linear; therefore, the Iodine Clock is a simple and effective stopping mechanism for the motor.
Prologue Casually during our regular weekday meeting, Siang and Thanos discussed the idea of having two teams from Chem E Car present posters at the annual Generate conference hosted by Clean Energy BC. We decided to be that second team. With less than a month away, we had to choose a topic, become experts in that topic and design a poster in hopes of winning the competition and $500 prize money.
Introduction With the Student AIChE/CACHE National Mobile Device APP Competition around the corner, our team has been working hard in exploring different ideas to showcase our creativity in a practical design. As part of our lab course field trips, many of us have visited local breweries to gain a general overview of how the general brewing process works. Keeping this in mind, we decided to try something that none of us have done before: creating an app to automate the brewing of craft beer.
