Profiles of gas holdup in a gas liquid countercurrent bubble column using electrical resistance tomography

open access: yes, 2007
In order to improve the performance of a countercurrent bubble column, radial variations of the gas holdup and mean holdups were investigated in a 0.160m i.d.

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

open access: yesAdvanced Healthcare Materials, EarlyView.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.

Gas Holdup Tool applications in production logging

open access: yes, 1998
The Gas Holdup Tool (GHT) has been developed to improve understanding of downhole flowing conditions and to expedite the evaluation of the reservoir. Less than 3 ft in length, GHT is a 1-11/16-in-OD through-tubing production logging tool, which directly ...

The effect of liquid phase properties on gas holdup in bubble column reactors

open access: yes, 1987
The effect of liquid phase properties on gas holdup in bubble column reactors was investigated within a large set of gas-liquid systems. Air was used as a gaseous phase in all experiments, liquid phases included distilled water and aqueous solutions of ...
