In order to help understand the wide scatter in the reported fatigue properties reported for bulk metallic glasses, the roles of free volume and residual stress in affecting the fracture and fatigue behavior of a Zr44Ti11Ni10Cu10Be25 bulk metallic glass were examined. Different residual stress and free volume states were achieved by annealing below the glass transition temperature.

A significant untapped renewable energy source exists in the world's oceans: it is estimated that if 0.2% of the oceans' untapped energy could be harnessed, it could provide power sufficient for the entire world. This presentation discusses the opportunities for ocean wave power to become a new, reliable and clean source of affordable renewable energy. Wave energy research and developments at Oregon State University (OSU) will be presented, in addition to the developing opportunities for the State of Oregon to become a leader in wave power.

Acknowledging that lecture-based teaching methods are insufficient at promoting significant conceptual gains for students in the introductory college science course is only the first step toward increasing students' understanding. Researchers at the Center for Astronomy Education (CAE) at the University of Arizona have been developing and evaluating the effectiveness of learner-centered instructional materials that put students in an active role in the classroom.

Integrated spintronic biochip platforms are being developed for portable, point-of-care diagnostic applications. The platforms consist of a microfluidic unit where the bioassay takes place, an arraying and detector chip consisting of target arraying current lines and integrated magnetoresistive sensors, and electronic control and readout boards. Probe biomolecules are immobilized by microspotting over sensor sites, and target biomolecules, labeled with magnetic nanoparticles are arrayed over the probe sites ( magnetically assisted hybridization).
