PCM: GCC Design Studio at MSU

The prize from the American Institutes of Architects (AIA) awared $100,000 in research funding for the team, which in addition to Portland State University professor of architecture, Sergio Palleroni, includes Bryan Bell, executive director of Design Corps; Roberta Feldman, professor at the University of Illinois at Chicago; and David Perkes, AIA, director of Gulf Coast Community Design Studio at Mississippi State University. Theirs was one of nearly 500 proposals considered for the prize, which is given every two years.  Read more...

PCM: blood vessel repair

The polymer technique was five times faster than the traditional hand-sewing method, the researchers say. It even worked on superfine blood vessels, just 0.2 millimeters wide, which would not work with a needle and thread. The team monitored test subject rats for up to two years after the polymer suturing, and found no complications.  “This new technology has potential for improving efficiency and outcomes in the surgical treatment of cardiovascular disease,” the authors say.

Perlite as a PCM

Properties of PCM that are desirable for residential use include: (1) A melting temperature above 25°C (77°F), (2) material is low cost, (3) not toxic, corrosive, or hydroscopic, and (4) commercially available in sufficient quantities for producers to incorporate into ordinary building materials.
Researchers have identified a number of materials that meet most of the specifications. For example, paraffin compounds (linear crystalline alkyl hydrocarbons) are commercially available from petroleum refining or polymerization. Some manufacturers have demonstrated processes that successfully incorporate paraffin beads into wallboard. However, more research is needed before the technology can be marketed.  Read more ....

PCM: Cooling Homes

MIT's Technology Review reports on paraffin wax capsules could use the cold of evening to cool rooms in the day.  Building materials that absorb heat during the day and release it at night, eliminating the need for air-conditioning in some climates, will soon be on the market in the United States.
