A new chem. crosslinking scheme was utilized for the formation of degradable poly(ethylene glycol) hydrogels suitable for the delivery of protein drugs. An aq. soln. contg. a PEG-multiacrylate and solid particles of albumin was mixed with an aq. soln. cont ...
The molecular engineering of cell-instructive artificial extracellular matrices is a powerful means to control cell behavior and enable complex processes of tissue formation and regeneration. This work reports on a novel method to produce such smart biomat ...
The stop-effect, a drastic increase of the reaction rate when the feed concn. of a reactant is switched to zero, was studied for the dehydration of ethanol to ethylene on y- alumina at 180 and 200 DegC. Two basic models exist in the literature to describe ...
Polymer networks of poly(ethylene glycol) (PEG) in densely cross-linked matrices of acrylic acid (AA) and trimethylolpropane triacrylate were synthesized as biospecific cell adhesive substrates. Networks grafted with synthetic adhesion peptides produced su ...
Interspecies competitive effects on the degradation of two alkyl halides (1-bromo-2-chloroethane, BCA, and 1,1,2-trichloroethane, 1,1,2-TCA) and three vinyl halides (trichloroethylene, TCE; cis-dichloroethylene, cis-DCE; and trans-dichloroethylene, trans-D ...
Carrier-mediated drug delivery has emerged as a powerful methodology for the treatment of various pathologies. The therapeutic index of traditional and novel drugs is enhanced via the increase of specificity due to targeting of drugs to a particular tissue ...
The deactivation kinetics of catalysts for vinyl acetate (I) [108-05-4] manuf. from ethylene, AcOH, and O were studied in regard to product inhibition. Surface reactions were studied using models and a 2-parameter model was discussed which satisfactorily d ...
A gravimetric app. contg. catalyst particles (H2SO4 on silicate) is used to det. the ethylene [74-85-1] absorption rate during the prepn. of vinyl acetate [108-05-4] from ethylene and AcOH. The influence of the absorption process on the overall reaction at ...
We present polymeric hydrogel biomaterials that are biomimetic both in their synthesis and degradation. The design of oligopeptide building blocks with dual enzymatic responsiveness allows us to create polymer networks that are formed and functionalized vi ...
