growth and physiology responses of phragmites australis to combined drought Flooding Condition in inland saline alkaline marsh northeast china
Ecological Engineering, 2017Co-Authors: Bolong Wen, Fei Yang, Fuyi YangAbstract:Abstract As a special ecosystem in western Songnen Plain, Northeast China, Phragmites australis saline-alkaline marsh degrade to saline meadow or even alkaline spots progressively, due to the interruption of the water supply. It was the basis to restore the saline-alkaline marsh successfully, that understanding the responses of P. australis to Flooding in dried saline-alkaline marsh. Pot experiments were conducted to explore an optimum Flooding time for restoring inland saline-alkaline marshes by determining the changes in the growth and physiology of P. australis in response to five different combined drought-Flooding treatments (DF04, DF13, DF22, DF31 and DF40). The results showed that the long-term Flooding without drought Condition (DF04) was not the most favorable Condition for the largest effective accumulation of plants biomass, although it gave rise to the highest population height. The combined drought-Flooding treatment that drought in one month and Flooding in subsequent three months (DF13) was proved as the optimum Flooding time, not only obtaining the largest biomass, but also effectively reducing the sodium ion absorbed by plant shoots. Subsequently, the accumulation of sodium ion in plant shoots increased significantly with the delay of Flooding from DF22 to DF40 treatments, and the significant enhanced photosynthetic activity implied the evident physiological responses to drought stress.

effect of thickness and hydrophobic polymer content of the gas diffusion layer on electrode Flooding level in a pemfc
Journal of The Electrochemical Society, 2005Co-Authors: Trung Van NguyenAbstract:The effect of thickness and wetproof level of the gas diffusion layer on electrode Flooding and cell performance was investigated. Three types of gas diffusion media were tested: SGL SIGRACET carbon papers, with and without a microporous layer, and Toray TGPH carbon paper without a microporous layer. Overall, it was found that SGL carbon paper with the microporous layer gave the best fuel cell performance even at low air stoichiometries. It was also found that adding poly(tetralluoroethylene) (PTFE) to the gas diffusion layer could enhance gas transport and water transport when a cell operates under Flooding Condition, but excessive PTFE loading could lead to a high Flooding level in the catalyst layer. It is our opinion that a combination of hydrophobic pores for gas transport and hydrophilic pores for liquid water transport within the macroporous layer is needed. It is also our opinion that the optimal ratio of hydrophobic and hydrophilic pores depends on the pore size and its distribution. Finally, it was observed that without the microporous layer, thinner gas diffusion materials were more sensitive to liquid water accumulation than the thicker ones.
