New method to test fireproofing material

harminka — Fri, 03 Oct 2008 06:53:10 -0500

In a high-temperature blaze, how well does a fireproofing material shield a building’s important steel structures from heat? Answering this question has been surprisingly difficult, but it is important information for builders selecting high-performance fire-resistive materials and for scientists conducting computer simulations that investigate fires.

Oregon physicists find possible electron switch

A water repellent developed by researchers at the Department of Energy's Oak Ridge National Laboratory outperforms nature at its best and could open a floodgate of commercial possibilities.

Thermoelectric materials are 1 key to energy savings

harminka — Wed, 21 Nov 2007 12:31:04 -0600

Breathing new life into an old idea, MIT Institute Professor Mildred S. Dresselhaus and co-workers are developing innovative materials for controlling temperatures that could lead to substantial energy savings by allowing more efficient car engines, photovoltaic cells and electronic devices.

Probing rare material spin state at NIST

harminka — Sat, 15 Sep 2007 13:00:51 -0500

A team of international physicists that includes researchers from the National Institute of Standards and Technology (NIST) has found experimental evidence of a highly sought-after type of arrangement of atomic magnetic moments, or spins, in a series of materials.

New pathways from outside cell-to-cell nuclei discovered

harminka — Sat, 11 Aug 2007 01:43:47 -0500

A team of Brooklyn College researchers has shattered a long-held belief that no direct pathway exists between material outside of a cell and the cell nucleus. (The cell is the smallest metabolically functional unit of life.)
