3-D printing processes, which use drop-on-demand inkjet printheads, have great potential in
designing and prototyping magnetic materials. Unlike conventional deposition and lithography,
magnetic particles in the printing ink can be aligned by an external magnetic field to achieve both
high permeability and low hysteresis losses, enabling prototyping and development of...
A comparison was made of Al₂O₃ films deposited on Si via prompt inorganic condensation (PIC)
and atomic layer deposition (ALD). Current–voltage measurements as a function of annealing
temperature indicate that the solution-processed PIC films, annealed at 500°C, exhibit lower
leakage and roughly equivalent breakdown strength in comparison to ALD films....
Over the past several decades, quality climate information has become extremely valuable to environmental decision makers, yet little is known about how this information is distributed within a social network of professionals. This study focuses on a climate knowledge network associated with a NOAA Climate Impacts Research Consortium (CIRC) study...
To determine if a storm event (i.e., high winds, large volumes of precipitation) could
alter concentrations of Vibrio vulnificus and V. parahaemolyticus in aquacultured oysters
(Crassostrea virginica) and associated surface water and sediment, this study followed a
sampling timeline before and after Hurricane Irene impacted the Chesapeake Bay estuary in...
The current work sought to develop predictive
models between time-weighted average polycyclic aromatic
hydrocarbon (PAH) concentrations in the freely dissolved
phase and those present in resident aquatic organisms. We
deployed semipermeable membrane passive sampling devices
(SPMDs) and collected resident crayfish (Pacifastacus
leniusculus) at nine locations within and outside of the...
A method for measuring the magnetostriction of thin films using a vibrating sample
magnetometer is described. We describe the design of a custom sample holder to apply an
adjustable bending stress to the sample during measurement and observe the resulting change in
the M-H loop.
A novel patterning technique that creates magnetization patterns in a continuous magnetostrictive
film with surface acoustic waves is demonstrated. Patterns of 10 μm wide stripes of alternating
magnetization and a 3 μm dot of reversed magnetization are written using standing and focusing
acoustic waves, respectively. The magnetization pattern is size-tunable,...
Many public opinion surveys indicate that patients desire an open dialogue on spirituality/religion with their physicians. What role does spirituality play in the physician/patient relationship and in what contexts do these conversations arise? What do physicians think about the appropriateness of such discussions? Because the role of spirituality in clinical...
