College Chemistry Department by Kathleen Sampson‚ a Ph.D. Candidate at the University of Toronto. Sampson presented about the intersections of chemistry and engineering in regards to innovating new materials to produce solar energy. Sampson discussed organic solar cells‚ a type of solar energy technology that converts sunlight into electricity using “Earth-abundant‚ carbon-based materials” according to her lecture. These solar cells are cheaper to manufacture compared to current practices and could be

Short Poetry Paper Organic poetry generally seems to be the most common type of poetry. To me‚ they are the easiest to come by‚ but aren’t always the easiest to understand simply because they are taken straight from random thoughts of the poet and jotted down on paper‚ a napkin‚ or any kind of canvas available to that poet. Although they don’t have much planning and are difficult to decipher‚ it is possible. When Patricia Smith wrote “What It’s Like to Be a Black Girl (for Those of You Who Aren’t)”

I have very few memories of the day that I obtained my first concussion in the spring of my sophomore year at Tulane. I was feeling stressed that day‚ I had an Organic Chemistry quiz the next morning and was squeezing in study time between classes and diving practice. At practice‚ thoughts of Organic Chemistry were distracting me from my work out; I remember leaving the board‚ and then seeming to reappear on the pool deck with my coach barking at me in a language I did not understand. I just stared

were used to determine the melting point. 6. The bicarbonate extract was acidified with concentrated HCl. A piece of litmus paper showed that it was acidic. 7. The benzoic acid was extracted by shaking it with25ml portions of dichloromethane. The organic extracts were collected in a pre-weighed Erlenmeyer flask and evaporated on the steam bath. The mass of Benzoic acid produced was determined. RESULTS (i) Naphthalene: 0.85g; Benzoic acid: 0.71g (ii) The melting point of Naphthalene: 80-89º

project was conducted to test the effectivity of organic and synthetic fertilizers when apply on okra plant. It also aims to test whether‚ which is better to use between the two fertilizers. In order to conduct the study‚ we have used okra seeds‚ polyethylene bag‚ and dried leaves as organic fertilizer‚ synthetic fertilizer‚ synthetic fertilizer‚ and natural soil. We have planted each polyethylene bag with 3 seeds of okra‚ labeled it as Setup A (Organic fertilizer)‚ Setup B (Synthetic Fertilizer)‚ And

Experiment No. 1: MELTING POINT AND BOILING POINTS OF ORGANIC COMPOUNDS ABSTRACT The properties of organic compounds depend on their chemical structures. Intermolecular forces of attraction affect physical properties such as melting and boiling point. Through the Thomas Hoover apparatus‚ the melting point of 8 test compounds was determined. Salicylic acid exhibited the highest melting point while naphthalene‚ the lowest. The stronger the intermolecular forces of attraction‚ the higher the melting

Do we live in a world where violent resistance is no longer a realistic option to oppose an oppressive regime? The Kenny reading showed that non-violence is a path that can lead to regime change. Why is that? Is it because a non-violent struggle is morally superior to a violent one‚ and is therefore difficult to oppose? After all‚ it’s difficult to justify violence against those who struggle without violence‚ for human rights‚ justice and democracy‚ things most people desire. To repress them would
