Virginia Tech researchers have developed ultra-thin heat protective coatings for rockets and microelectronics by studying hybrid organic/inorganic molecules. The coatings, which are less than two nanometers thick, offer improved fuel efficiency and weight reduction in space applications.
A recent study found that heating fluorinated polymers in a frying pan releases toxic chemicals, including ozone-destroying chlorofluorocarbons. The long-term environmental impact of these persistent compounds is still unknown.
A team of researchers from Penn State has successfully developed a polymer coating that adheres to the surface of optical glass, particularly phosphate glasses. This breakthrough enables new applications for these glasses in fields such as optics and photonics.
Scientists have fabricated erasable polymer multilayers that can be selectively destroyed by environmental stimuli, enabling controlled release of embedded compounds. These films have potential applications in medicine and materials science.
Researchers discovered that flexible polymers behave differently on surfaces compared to in bulk, with a stronger dependence on chain length. The study used two-photon fluorescence correlation spectroscopy to monitor individual molecule motions and found that chains 'entangle' with the surface, causing them to flatten.
Scientists from Boston University's Center for Polymer Studies use modern physics to analyze heartbeats, finding complex multifractal properties in healthy hearts. This discovery could help doctors diagnose cardiac disease more effectively, potentially avoiding the harm caused by medication aimed at eliminating variability.
Researchers create microscopic patterns on surfaces using microcontact printing, then build up layers of a polymer material over the pattern. The technique enables complex pattern creation and automation of the patterning process.
The implant is a button-sized polymer that releases hydromorphone over one to three months, providing steady pain medication. It could be used in developing nations where cancer rates are high but limited treatment options exist, and potentially as an alternative to oral methadone treatment for heroin addicts.
