Calcium Phosphate ceramic has been widely used in bone tissue engineering due to its excellent biocompatibility and biodegradability. However, low mechanical properties and biodegradability limit their potential applications. In this project, hydroxyapatite (HA) and calcium phosphate bioglass were used to produce porous tri-calcium phosphate (TCP) bioceramic scaffolds. It was found that porous ...

Activated sludges are an inoculum source commonly used in biodegradation studies, as wastewater treatment facilities constitute an entry point to the environment for many chemicals. In this paper, the main issues relating to the use of activated sludge in biodegradability tests are presented. Special attention is also devoted to discussing the factors affecting both the activity of the microbia...

dye removal from effluents of textile industries of iran was investigated through biodegradabilitymethod and membrane technology . basic, reactive,disperse and acidic dyes were selected, based onusage rate in iran. the zahen - welenze method (iso 9888) was applied to study the biodegradabilityof dyes. results showed the final cod and dye removal (%r) as (%61,% 57), (%73, %76), (%25, %14),and (%...

The biodegradation probability program for Microsoft Windows (BIOWIN) models have been developed by the Syracuse Research Corp. (SRC) on behalf of the US EPA since the 1980s. Most BIOWIN models estimate the probability of rapid aerobic biodegradability. BIOWIN7 is the exception as it estimates the probability of rapid anaerobic biodegradability in the presence of heterogeneous microorganisms. A...

Progress on biodegradable aromatic/aliphatic copolyesters based on aliphatic and aromatic diacids, diols and ester monomers was reviewed. The aromatic/aliphatic copolyesters combined excellent mechanical properties with biodegradability. Physical properties and biodegradability of copolyesters varied with chain length of the aliphatic polyester segment and atacticity of copolyesters. The proces...

Point-of-care testing is a rapidly evolving yet complex field. As your POCT program grows, take the time to understand the regulations, as they are important to ensuring patient safety. The regualtions established CLIA are designed to ensure consistent and reliable laboratory results that can accurately impact patient care. When beginning your look into POCY, first identify what labs can direct...

The construction, characterization and surgical application of a multilayered iron oxide-based macroporous composite framework were reported in this study. The framework consisted of a highly porous iron oxide core, a gelatin-based hydrogel intermediary layer and a matrigel outer cover, which conferred a multitude of desirable properties including excellent biocompatibility, improved mechanical...
