Collapse pressures of biodegradable stents

Biomaterials, 2003
Biodegradable stent prototypes were produced from poly L-lactic acid polymers with different molecular weights. The effects of molecular weight, drug incorporation and stent design on the collapse pressure of the stents were evaluated. While molecular weights did not show a significant effect on the collapse pressure of the stents, drug incorporation ...

Cake Collapse in Pressure Filtration

Langmuir, 2001
Aqueous dispersions of latex particles have been aggregated by addition of Ca2+ ions and then filtered in a pressure filtration cell. The filtration cakes have been examined through small-angle neutron scattering, void volume fraction measurements, and permeate flux measurements.

Collapse pressures of bilayered biodegradable stents

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2006
AbstractBiodegradable helicoidal stent prototypes made up of layers of poly‐L‐lactic acid (PLLA) and poly(L‐lactic‐co‐glycolic acid) (PLGA) polymers were fabricated by temperature conditioning the stents at different stages of fabrication. The process incorporated elastic memory, or self‐expandability in the stent, which is desirable to minimize stent ...

Superlubricity Enabled by Pressure-Induced Friction Collapse

The Journal of Physical Chemistry Letters, 2018
From daily intuitions to sophisticated atomic-scale experiments, friction is usually found to increase with normal load. Using first-principle calculations, here we show that the sliding friction of a graphene/graphene system can decrease with increasing normal load and collapse to nearly zero at a critical point.

Capillary Negative Pressure Measured by Nanochannel Collapse

Langmuir, 2010
A new method is presented to measure capillarity-induced negative pressure. Negative pressures of several bars have been measured for five different liquids (ethanol, acetone, cyclohexane, aniline, and water) over a range of surface tension. Capillary negative pressure was measured in 79 +/- 3 nm silica nanochannels on the basis of the determination of

Vessel growth and collapsible pressure-area relationship

American Journal of Physiology-Heart and Circulatory Physiology, 1997
The role that the pattern of vessel wall growth plays in determining pressure-lumen area (P-A) and pressure-compliance curves was examined. A P-A vessel model was developed that encompasses the complete range of pressure, including negative values, and accounts for size given the fixed length, nonlinear elastic wall properties, constant wall area, and
