...) cryogel membranes were tested for their ability to stretch with uniaxial tension tests and for puncture strength with a modified ASTM method. Additionally, PVA cryogel covered stents were made by coating expanded bare metal stents. These covered stents were then hand-crimped onto a balloon catheter...

... is such that a liquid phase containing the dissolved microsphere matrix material reaches a continuous phase after a silicon membrane with micron-sized perforations, where microdroplets are formed. After the droplet is detached from the membrane, the solvent diffuses out of the droplets into a continuous phase leading...

...M. Gaumet; J. Xi; D. Barriet; R. A. Siegel Temperature and pH-sensitive ABC triblock polymers were prepared to form hydrogel membranes capable of changing their structure in response to environmental stimuli, allowing drug release, from a micro implantable device, in short and repetitive pulses. We...

...K-.Y. Song; U. Häfeli; B. Stoeber; M. Chiao; W. J. Zhang A novel method to generate uniform biodegradable microspheres for drug delivery applications has been developed. A liquid phase containing the dissolved microsphere matrix material reaches a continuous phase through a silicon membrane...

...Zhongping Huang; Weiming Zhang; Jianping Yu; Dayong Gao The nonuniformity of pore size and pore distribution of the current hemodialysis membrane results in low efficiency of uremic solute removal as well as the loss of albumin. By using nanotechnology, an anodic alumina membrane (ceramic membrane...
