Understanding the transport characteristics and establishing a way to estimate potential gas flow is very important to guide shale gas reserve estimation and recovery schemes.
This combination of catalyst types and high gas flow rate revealed the potential for growing various SiNWs, including kinked SiNWs (with Au), ultra-thin SiNWs having diameters about 5 nm (with Ti), rough-surfaced SiNWs (with Mn), and ribbon-shaped SiNWs tens of microns in width (with Fe).
For the first time, the electrospray ionization (ESI) parameters of probe position, voltage potential, sheath gas flow rate, auxiliary gas flow rate, and ion transfer tube temperature were thoroughly studied and optimized for each phenol by a univariate approach.
Experimental design was applied to assess the effects of the LC ESI MS parameters (mobile phase flow rate, drying gas flow, nebuliser pressure and capillary potential) on the obtained signal and to optimize the values in order to provide maximum sensitivity and detectability.
Although electric potential and gas flow appear to have similar effects on the period-doubling bifurcation process for this system, the relative impact of electrostatic forces, as measured in terms of electric Bond number for conducting liquid and gas phases, is smaller.
By educating anesthesiologists and appropriate staff on environmentally preferred anesthetic choice and avoiding excessive fresh gas flow rates, the ozone depletion potential and greenhouse gas emissions of hysterectomies can be reduced 65 95% for abdominal and vaginal hysterectomies.
The optimal parameters were as follows: IonSpray voltage −4,500 V, interface temperature 200 °C, curtain gas flow rate 10 L/min, and declustering potential −75 V.
Here we describe a novel ion mobility experiment using countering potentials and gas flow fields as well as two cyclic ion confinement methods which operate in a mobility-selective manner.
In addition, we have proved the evidence of the "bulldozing effect (or pore blocking)" for air injection in light oil reservoirs, which has the potential of redirecting gas flow to improve sweep efficiency (Jia and Sheng 2016).
