Glass of beer and can

March 22, 2011

A Seminar on the Science of Beer

They may have been Puritans, but beer was their choice of beverage to bring on a voyage to America.

Beer was safer than water because it had been boiled, not for safety, but to bring out bitterness, flavor and aroma. It’s one of a chain of processes that convert raw ingredients into the world’s most widely-consumed alcoholic beverage.

It turns out that beer requires a surprising amount of science.

molecular tug of war

Molecular tug-of-war could lead to new materials

Tug-of-war isn’t just for play. In the chemistry world, the game could identify a Saran-wrap-like material that instantly heals microscopic tears in its own structure.

skin cells

Sidewalks of skin cancer

New, high resolution images suggest that the location and amount of skin pigments could tell pathologists whether a mole has turned cancerous.

Skin cells contain two kinds of pigments or melanins: pheomelanin, which is reddish or yellow, and eumelanin, which is dark and brownish.

merged molecules

Tangling the microscopic ladder

If a ladder had more than one rung at each step, it would look awkward and would be a bit dangerous to climb. Ladders in the microscopic world were thought to be similar in structure, having only one particle, or rung, in each step in the lattice of a crystal.

But theorists have conceived of structures where multiple particles could sit at one lattice site and have now simulated how these structures might form and behave for a range of temperatures, pressures and densities.

nanotube

November 19, 2010

All wrapped up

It’s not easy being a nanontube. Yes, the small-scale carbon structures are enticing because of their unworldly, strength, quantum mechanical and lectrical properties. But the tubes have issues. First, they’re almost always in bundles, making them difficult to manipulate. And they really only like to live in water;in any other medium, their alluring characteristics disappear.

Life as a Freshman Researcher

Many freshmen enter college with no idea what they want to do with their life. Not Anand Kornepati (KORN-nuh-pah-ti), a Trinity ’14 student who has long since decided on his future in the medical field.
