To further explore the effect of Ni3S2@C-4 on the hydriding reaction of MgH2, the Johnson–Mehl–Avrami–Kolmogorov (JMAK) and Arrhenius equations were employed to calculate the apparent activation energy (Ea). The JMAK equation can be written as follows [12,18]:(1)ln[−ln(1−f(t...
Furthermore, the adsorption isotherm of SO4 2− by Mg−Al oxide obeyed the Langmuir equation. The maximum adsorption amount was 2.0 mmol g−1, or 4.0 meq g−1, indicating that Mg-Al oxide has a large capacity for uptake of SO4 2− from H2SO4.Tomohito Kameda...
Unweighted fitting of Equation (1) to the collected data yields: 𝜂𝑠 =−0.16(𝜂𝑓)0.49+0.90ηs =−0.16(ηf)0.49+0.90 (2) with r2 = 0.75 (when considering uncertainties on individual values of 𝜂𝑓ηf). This line asymptotically approaches 𝜂𝑠ηs≈ 0.8 as 𝜂𝑓ηf...
The equation matches the Langmuir isotherm if the value of β is equal to 1. When the value of the parameter aR·Ceβ is much greater than 1, the equation fits the Freundlich isotherm. The ratio KR/aR determines the degree of adsorption....
points among intervention-arm patients. None of the patients in the standard arm were able to achieve the study’s primary end point (post-dialysis systolic blood pressure <140 mmHg for four weeks). The 2 drop-outs reported in the intervention arm were due to hyperkalemia (>5.5 mEq/L)....
