The ice skates worn by this year's hockey players, figure skaters and speed skaters are vastly different from what were once used. Melissa Hines, the Director of the Cornell University Center for Materials Research, and Sam Colbeck, a retired scientist from the U.S. Army Cold Regions Lab, explain how innovations in boot and blade design help skaters perform better than ever before.

Friction always creates heat. Brakes and tires depend on friction to work, but more friction isn’t always better. In the engine, friction is never good and engine builders use everything from oil to high-tech coatings to get a little extra horsepower.

Addressing the Challenge of Truly Large Scale Photovoltaics

submitted by: RASEIBoulder
Addressing the Challenge of Truly Large Scale Photovoltaics: the Industrial and Thermodynamic Potentials of Organic Solar Cells In order for photovoltaic systems to ultimately provide a considerable fraction of the world’s energy needs they will need to meet a number of stringent performance metrics regarding their cost, efficiency, and robustness. In addition, they will need to be manufactured with very high throughput methods in order to realize the enormous production scales...

All Obstacles Removed ... the Journey Continues for Brain Cancer Patient

submitted by: mdanderson
Aidan Immroth lost his battle to brain cancer in November of this year, but at the end of his brief 13 years on this earth, Aidan accomplished something really huge -- actually as big as an elephant -- a painting using a live elephant as the canvas that is! Part of the Pediatric Education and Creative Arts Program at MD Anderson Children's Cancer Hospital, Aidan had a vision to paint a real elephant and it became reality through the help of Ian Cion, MD Anderson Children's Cancer Hospital's...

Re-evaluating The Hubbert Curve And The Global Petroleum Revolution: A New Era - Details

submitted by: RASEIBoulder
Summary: Why have the predicted global oil and natural gas shortages and demise of civilization by 2010 related to these vanishing supplies not occurred? The static view has created a pessimistic outlook based on historical perspective such as the Hubbert curve analysis which results in the inescapable and inevitable depletion that will result in catastrophic consequences for civilization. A new paradigm, a dynamic or petroleum system view demonstrates a different and more optimistic...

Energy Efficiency In Buildings And Heat Supply Solutions: A German Perspective For The Nuclear Shutdown

submitted by: RASEIBoulder
Beginning with some background information on the unique German position regarding the energy supply eliminating any nuclear power by 2022 but enforcing the use of renewable energy sources, the challenges for both the building and the power generation sector will be highlighted. The talk will introduce opportunities to improve energy performance of buildings by new and innovative HVAC concepts as well as for increasing the penetration of renewable and environmental energy sources for heat...

The folding and binding landscape of ankyrin repeat proteins

submitted by: icamvid

Elizabeth Komiups gives a talk at the RPP08 conference about the I?B? / NF-?B complex. She discusses the interface between the two proteins, the stabilization of the complex by "hotspots", and the folding of I?B? upon binding.
