WELCOME

Sci-Mind is a revolutionary new learning program for professional scientists who are seeking an enriching, flexible, customizable learning solution that will truly expand their knowledge.

We designed this page to provide all the latest news and developments on Sci-Mind™ for our contributors, stakeholders, and each other.

In 2012, we will debut the first two science topics in this program: Toxicology for the Scientist and Separation Science. Read more about Sci-Mind and then sign up to help.

As a contributor to a fast moving project, we know that it's important for you to have the latest information so that you can be most efficient with your time. So this site will help to ensure that everyone is up to date, regardless of how fast we're moving things along.

We know you are busy, but we want you involved and up to date.  Keep your finger on the pulse via the Sci-Mind™ Cork Board.

SCI-MIND CHALLENGE
Toxicology
Q. Organs from patients dying (or dead) from ingestion of poison hemlock plant material can be transplanted safely without risk of poisoning the organ recipient. True or False?
A. True. Some organs from humans dead or dying after ingestion of hemlock have been demonstrated as safe to transplant. Death in humans is caused by temporary respiratory paralysis leading to suffocation and death of cardiac and brain tissue, but paralysis usually wears off after 48-72 hours if the body is kept on artificial ventilation; the toxin is eliminated.
Separation Science
Q. Which mobile phase gives the best combination of increased efficiency and speed?

  • Nitrogen
  • Helium
  • Hydrogen
A. Hydrogen is the correct answer relative to Nitrogen and Helium because when HETP (height equivalent to theoretical plates or L/N) is plotted versus average linear velocity (x-axis) for different mobile phase gases, H2 maintains the lowest HETP (best efficiency) over the widest and highest range of flow rates. In other words, it has the flattest curve (see plot here).
