Red soil for sediment capping to control the internal nutrient release under flow conditions

Lei Xia, Guo Liu, Chunmei Chen, Meiyan Wen, Yangyang Gao

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 6, doi: 10.1007/s11783-016-0886-2

Abstract: Red soil (RS) was firstly used as sediment capping material under flow conditions.RS capping can effectively reduce the N and P release from sediment.The N and P that were released were effectively controlled by RS capping.total N (TN), ammonium (NH -N), total P (TP) and soluble reactive P (SRP) of the overlying water by RS capping

Self-etching adhesives: possible new pulp capping agents to vital pulp therapy

Chun CUI, Xiu-Neng ZHOU, Wei-Min CHEN

Frontiers of Medicine 2011, Volume 5, Issue 1, Pages 77-79 doi: 10.1007/s11684-010-0104-8

Abstract:

Pulp capping is one of the solving for keeping vital pulp in the case of dentin caries, reversiblebacteria on the cavity walls or in the pulp was the major factor that leads to the failure of pulp cappingTraditional pulp capping agent, calcium hydroxide, may not prevent microleakage.

The effect of capping with natural and modified zeolites on the release of phosphorus and organic contaminants

Shujuan SUN, Lei WANG, Suiliang HUANG, Teng TU, Hongwen SUN

Frontiers of Chemical Science and Engineering 2011, Volume 5, Issue 3, Pages 308-313 doi: 10.1007/s11705-010-0561-2

Abstract: A microcosm system that included river sediment, water and different zeolite capping materials (naturalsurfactant-modified zeolite (SMZ), or aluminum modified zeolite (AMZ)) was designed to study the effect of cappingFor the same amount of the three capping materials, the efficiency of phosphorus inactivation was inWhen natural zeolite was used as the capping material, there was no effect on the release of pyrene andpyridine, whereas capping the sediment with SMZ or AMZ inhibited the release of pyrene and pyridine
