Energy squeeze: Squeezing silicone polymers produces chemical energy but raises doubts about implant safety

Scientists turned to squeezed polymers and free radicals in a search for new energy sources. They found both promise and problems. The researchers demonstrated that radicals from compressed polymers generate significant amounts of energy that can power chemical reactions in water. They also discovered that a silicone polymer commonly used in medical implants releases a large quantity of harmful free radicals when the polymer is under only a moderate amount of pressure.

To revert breast cancer cells, give them the squeeze

Academics / General Science : Science Daily (2 years ago)

Researchers have found that compression can guide malignant breast cells back to a normal growth pattern. The findings demonstrate the influence of mechanical forces on a cell's destiny. Read Post

Silicone liquid crystal stiffens with repeated compression

Academics / General Science : Science Codex (2 years ago)

HOUSTON – (April 29, 2013) – Squeeze a piece of silicone and it quickly returns to its original shape, as squishy as ever. But scientists at Rice University have discovered that the liquid crystal phase of silicone becomes 90 percen... Read Post

Squeezing Polymers Produces Chemical Energy But Raises Doubts About Implant Safety

Health : Medical News Today (3 years ago)

A polymer is a mesh of chains, which slowly break over time due to the pressure from ordinary wear and tear. When a polymer is squeezed, the pressure breaks chemical bonds and produces free radicals: ions with unpaired electrons, fu... Read Post
