Sentence examples for elevated hydrogen from inspiring English sources

Key parameters to ensure such desirable results are (i) the use of a shape-selective zeolite catalyst, such as ZSM-5 or ZSM-11, (ii) the application of relatively high reaction temperatures in the vicinity of 400 °C, and (iii) elevated hydrogen pressures around 6 MPa.

Besides hormone homeostasis, elevated hydrogen peroxide levels also trigger senescence (Bieker et al., 2012; Smykowski et al., 2010).

Isolated mitochondria from AD patients also show decreased complex IV activity as well as elevated hydrogen peroxide production [ 19].

Establishing tides in salt marsh studies is important because previous studies using permanently inundated plants documented reduced plant growth stemming from problems with flooded soils including altered redox potential (Armstrong et al., 1985) and elevated hydrogen sulfide concentrations (Mendelssohn and McKee, 1988; Portnoy and Valiela, 1997).

Much deepened hydrogenated layers (half of the specimen's thickness) with elevated hydrogen concentrations (6436 mg/m2) were acquired by employing the designed cyclic process.

A more promising approach is performing the TEM analysis at an elevated hydrogen back pressure rather than vacuum to stabilize the hydride phase.

The expression of HoxU is probably regulated independently by at least one of these promoters; this suggested that controlling expression of HoxU may provide significant insight for elevating hydrogen production, which proved correct since cloning only hoxU accounted for about half of the hydrogen produced by cloning hoxEFUYH.

Elevated levels of hydrogen sulfide [ 34] and increased CSE mRNA expression [ 5, 8] following LPS administration have been shown.

Although ethanol toxicity remains a concern, elevated concentrations of hydrogen and acetate in the treated zone suggest microbial activity (Mravik et al. 2003).

The rapid nucleation and growth of voids suggest elevated concentrations of hydrogen-vacancy defects near the dissolving surface.

The experiments changing the order of catalytic bed and Pd Ag membrane in the membrane reactor for steam reforming revealed that the elevated high pressures and hydrogen removal before catalytic steam reforming are advantageous for high hydrogen recovery.
