Abstract A novel design of a biodegradable carrier for drug delivery was established by constructing a supramolecular assembly of drugs and polymer backbones without any covalent bonds. A biodegradable polyrotaxane was synthesized in which α‐cyclodextrins (α‐CDs) as drug carriers were threaded onto poly(ethylene glyco…
We have studied the \ensuremath{\beta} relaxation of the density autocorrelation for a two dimensional model fluid via molecular dynamics (MD) simulation. We have found that correlated motions composed of many particles occur in the time scales of about 20 times the time scales of the thermal oscillations, which corre…
Electrochemomechanical polymer actuators were fabricated by using the electro-deposited poly-aniline film. Using LASER displacement meter, we can easily get the in-situ observation of the displacement and the cyclic voltammogram[1]. At the redox reaction from leuco-emeraldine salt to emeraldine salt(ES), PANI film sho…
Analytical solutions of and experimental results on the oxidation kinetics of carbon in a pore are presented. Reaction rate, reaction sequence, oxidant partial pressure, total system pressure, pore/crack dimensions, and temperature are analyzed with respect to the influence of each on an overall linear‐parabolic rate…
Human monocytes isolated from peripheral venous blood were assayed for their ability to adhere to various polymers. The culture supernatants were also assayed for the cytokines, interleukin-1 beta (IL-beta), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha). The polymers evaluated for adherence and cyt…

Abstract Diblock copolymers composed of poly(ε‐caprolactone) and poly(L‐lactide) were synthesized via sequential living ring‐opening polymerization of ε‐caprolactone and L‐lactide in dichloromethane initiated by Y 5 (μ‐O)(O i Pr) 13 (yttrium isopropoxide). A series of diblock copolymers was synthesized with ε‐caprolac…

Abstract Salting‐out phase equilibria are reported for lysozyme and α‐chymotrypsin from concentrated ammonium‐sulfate solutions. Supernatant and dense‐phase protein concentrations and the resulting protein partition coefficients are given as a function of solution pH and ionic strength. Phase equilibria with a trivale…
This article reports the fabrication of thick films of lead zirconate titanate (PZT) on platinum-buffered silicon substrates by screen printing. Crack-free films, up to 12 μm on a single pass, show a dielectric permittivity of 200, tangent losses of 0.05, remanent polarization of 2.5 μC/cm2, and coercive field of 40 k…
We have studied the effect of the polymer tilt angle for pretilt angle generation in nematic liquid crystal, 4-cyano-4 ′ -n-penthylbiphenyl (5CB) on rubbed polyimide surfaces. The polymer tilt angle was determined by measuring induced optical retardation produced in rubbed polyimide (PI) surfaces by rubbing. We sugges…
