Chapter 1 of 16: Attributes of a Good Scientist
To become good scientists, students must be passionate, hard working, curious and observant, but they must also be discriminating in choosing their research paths. (1 minute, 33 seconds)
Chapter 1 of 16: Attributes of a Good Scientist
To become good scientists, students must be passionate, hard working, curious and observant, but they must also be discriminating in choosing their research paths. (1 minute, 33 seconds)
Chapter 2 of 16: Anatomy of a Discovery
Schrock's initial discovery began when he was working at DuPont. His discovery opened up a whole new world of compounds with metal-carbon double bonds and, through his work at MIT, a completely new form of catalyst. (2 minutes, 44 seconds)
Chapter 3 of 16: Small Steps
Science is a series of steps. Asking simple questions often leads to complex discoveries. (44 seconds)
Chapter 4 of 16: Metathesis Dance
The process of metathesis is explained as a dance in which the dancers change partners. Chemical bonds, like dancers, break apart and come together in new pairs through this process. (1 minute, 37 seconds)
Chapter 5 of 16: Metathesis Masterclass
Schrock takes us through the metathesis process on the blackboard. (3 minutes, 20 seconds)
Chapter 6 of 16: History of Metathesis
Metathesis was discovered 50 years ago by Herbert S. Eleuterio. He was trying to make polypropylene, and he inadvertantly started this whole new field. (2 minutes, 5 seconds)
Chapter 7 of 16: Interest from Pharmaceutical Companies
Metathesis reactions are also very good at making interesting cyclic organic molecules, which is of great interest to pharmaceutical companies. Some of these drug candidates are almost on the market. (1 minute, 45 seconds)
Chapter 8 of 16: Industrial Polymers
Polymer developers are also using metathesis to create a variety of unique compounds. (43 seconds)
Chapter 9 of 16: Green Chemistry
Green chemistry is based on using less steps in a process, as well as using renewable materials and less energy. Processes involving metathesis reactions catalysed by Schrock's compounds are leading the way. (1 minute, 37 seconds)
Chapter 10 of 16: Renewable, Natural Chemistry
Natural precursors like cooking oils and a metathesis reaction can be used to create other natural products, like pheromones for pest control. This is not only very green in terms of production, but it means far less pes… (2 minutes, 32 seconds)
Chapter 11 of 16: Scientific Lineage
Schrock describes the ways in which scientific discovery builds on the work of other. He contends that science cannot be conducted in a vacuum, instead it is dependent upon scientists' constant communication with one ano… (1 minute, 24 seconds)
Chapter 12 of 16: Finding Scientific Solutions
There is still so much more to learn in science, but we require the right tools to do the work. Schrock contends that people don't really understand just what science has done for them. (1 minute, 33 seconds)
Chapter 13 of 16: Chaos in career choices
Your life is another chaotic experiment, you can never really see what else you might have done, and you will probably never get the same result twice. Schrock is happy with chemistry though, after all it is all around u… (57 seconds)
Chapter 14 of 16: Choosing Chemistry
Schrock went to Harvard to study physical chemistry, however, he was more interested in making molecules, and he therefore changed research groups to satisfy his curiosity. (1 minute, 7 seconds)
Chapter 15 of 16: Training the Next Generation
Schrock argues that it is important to alert students to the value of science at an early age. Helping students to appreciate that the contributions of science is a great accomplishment. (56 seconds)
Chapter 16 of 16: Worthy Science
You don't get Nobel Prizes for making an observation that you don't capitalize on, you must try to understand what you observe. That's where the great discoveries are found. (56 seconds)
Description
From his labs at MIT, Richard Schrock gives us the low down on the history of his discoveries and a simple breakdown of exactly what a metathesis reaction is.
