They used also enclosed DBD reactor driven by 2 kHz square-type sign of 6 kV voltage and 50% duty cycle achieving WCA of 116°. 3.3.3 Fluorosilane precursors Such precursors are easily dissociated in the plasma forming coatings with a strong –Si-O-Si- linking and enhanced hydrophobic...

The results demonstrated that the HN-CNT anode shows a much higher specific capacity of 494 mAh/g than CNTs, and still delivers the discharge capacity of 397 mAh/g in the 100th cycle (only 266 mAh/g for CNTs). Moreover, HN-CNTs display better rate capability than CNTs (30). Sign in...
Using Fe-speciation, redox-sensitive trace element (TE), and nitrogen isotope geochemical data, we show that there was an active N-cycle, primary productivity, oxygen production, and an oxygenated atmosphere with at least pockets of oxygenated ocean water, despite extreme environmental stress....

Simple models should then be used to propose assumptions for their structure. It is especially the case for the weathered zone of crystalline basements. The free-surface aquifer is controlled by chemical weathering reactions and by percolation processes. For example, in the case of non-limiting ...
Transcripts of the connected ammonium assimilating GS/GOGAT cycle did not follow the same pattern and were mainly unchanged by stress treatment. The chloroplast GS2 even tended to be generally transcriptional up-regulated (Additional file 5: Table S4). There was no uniform picture for amino acid ...
The buffer potential of the basic volcanic rock leads to the formation of harmonious humus states, so that in the case of deposition of up to 15 kg per hectare and year a new type of material cycle was formed, which was associated with the formation of the humus class clay brown dust. ...
The bigger picture Electrolyzing CO2 into value-added chemicals by using renewable electricity provides an elegant way to re-balance the anthropogenic carbon cycle. Integrated with the zinc dissolution/deposition reaction, CO2 electroreduction reaction can be applied in aqueous Zn-CO2 batteries (AZCBs)...
The intercalation of Li+ of the first cycle begins at around 2.0 V vs. Li/Li+; the curve exhibits a slope plateau at 0.8 V which arises from the combination of Li ions adsorption on the structural defects in basal planes of the graphene layers and the formation of solid electrolyte...
