Removal of aniline from water by an Fe(II)-nano-FeO@PAC heterogeneous catalyst in a Fenton-like process.

Aniline is a toxic chemical, and in many industries it is degraded by Fenton processes. In this study, an Fe(II)-nano-FeO@PAC heterogeneous Fenton catalyst (MFC) was prepared with a coprecipitation and impregnation method, which is simple, efficient and cost effective. The results of the magnetic performance tests showed that the MFC has typical ferromagnetism properties.

Ex vivo fat graft preservation: effects and implications of cryopreservation.

There are a variety of recommended methods for harvesting, treating, and utilizing autologous fat grafts. Previous work with the MTT assay illustrated that various preimplantation handling techniques had minimal effect on the viability of fat samples. This assay was used to test the viability of harvested fat samples after being stored for up to 8 days in a variety of conditions.

Human adipocyte viability testing: a new assay.

Background: Surgical experience and anecdotal data on the most effective method of harvesting, preparing, and injecting autologous fat grafts are inconsistent and conflicting. Because the limitation of fat grafting is its resorption, understanding how various handling techniques affect adipocyte survival is crucial to optimizing its long-term survival.

Objective: We sought to develop a method for assaying fat viability in its clinically used form and then to test several common techniques used in fat grafting for their effects on the viability of the fat.
