In-vitro toxicity study of poly(alkylphenol) as vulcanizing agent
In this study, cytotoxicity of various novel poly(alkylpehnol) derivatives which, one of constituent for vulcanizing agent, could be adjusted in medical elastic rubber applications were investigated under various conditions of cytotoxicity test. By MTT-assay which according to ISO 10993-5 regulation, we could figure out cell viability of mouse fibroblast in various sample conditions. Furthermor...
متن کاملSelf-healing concrete with a microencapsulated healing agent
We have developed a concrete material exhibiting self-healing properties and corrosion inhibition. This system involves a sodium silicate solution stored in polyurethane microcapsules present in the concrete matrix. The sodium silicate, released when the capsules are ruptured by propagating cracks, reacts with the calcium hydroxide in cement and produces a C-S-H gel that partially heals the cra...
متن کاملUpscaling the production of microencapsulated pancreatic islets.
Presently used single-needle air-driven droplet generators are incapable of producing sufficient numbers of islet-containing droplets in a sufficiently short time-period to allow for successfully grafting alginate-poly-L-lysine encapsulated islets in large animals or humans. We have designed an air-driven multineedle droplet generator, which increases the production rate by simultaneously produ...
متن کاملResponse of captive skunks to microencapsulated tetracycline.
A captive striped skunk (Mephitis mephitis) study was conducted between February and June 2004 at the United States Department of Agriculture, Animal and Plant Health Inspection Service, Wildlife Services National Wildlife Research Center, Fort Collins, Colorado, USA. The main objective was to determine the percentage of adult striped skunks that were marked after consuming placebo oral rabies ...
متن کاملAutonomic healing of PMMA via microencapsulated solvent
Fully autonomous, room temperature self-healing in PMMA is achieved for the first time through the use of microcapsules containing a solvent. Linear PMMA is embedded with microcapsules (ca. 300 mm) containing a liquid anisole solvent core and a small amount of linear PMMA polymer for healing of crack damage. Specimens containing a range of concentrations of microcapsules were fracture tested an...
