Effects of vegetation, season and temperature on removal pollutants in experimental floating treatment wetlands [PDF]
, 2010 The research and interest towards the use of constructed floating wetlands for (waste)water treatment is emerging as more treatment opportunities are marked out, and the technique is applied more often. To evaluate the effect of a floating macrophyte mat

In-situ X-ray spectroscopy of the electric double layer around TiO2 nanoparticles dispersed in aqueous solution: Implications for H2 generation [PDF]
, 2019 We report an experimental observation of a significant amount of hydroxide (OH–) created upon water dissociation and subsequently trapped around TiO2 nanoparticles dispersed in NH4OH aqueous solution. The hydroxide species is identified and quantified by

Stablity Study on CODMn, NO3-, NH4+ in Groundwater
Yankuang ceshi, 2014 CODMn, NO3- and NH4+ are important indicators to nitrite, nitrate and ammonia pollution in groundwater. There are significant differences between geological industry standards and national-international standards about the storage ways and time for these

Crystal Nucleation by Laser-Induced Cavitation\ud [PDF]
, 2011 High-speed and high-resolution photography have been used to investigate the relationship between creation, expansion, and collapse of a vapor cavity induced by a 6 ns laser pulse and the subsequent nucleation of crystals.
