Rate of penetration of a fluid into a porous body

Journal of Colloid and Interface Science, 1976
Abstract The rate of penetration of a liquid hydrocarbon or an alcohol into a glass capillary is more rapid if the capillary has been outgassed, than if its surface is covered with a duplex film of the liquid. The increase in rate is as large as 10%.

Mucus penetration enhanced lipid polymer nanoparticles improve the eradication rate of Helicobacter pylori biofilm.

Journal of Controlled Release, 2019
The resistance of Helicobacter pylori (H. pylori) to conventional antibiotic treatments becomes prevalent recently. The biofilm formation was found to be highly correlated with the antibiotic resistance of H. pylori in the last decades.

How To Improve Rate of Penetration In Field Operations

Proceedings of SPE/IADC Drilling Conference, 1996
Abstract A method has been developed that identifies which factors are controlling rate of penetration (ROP) in a particular group of bit runs. The method uses foot-based mud logging data, geological information, and drill bit characteristics, to produce numerical correlations between ROP and applied drilling parameters or other ...

Increased Rate of Penetration Through Automation

SPE/IADC Drilling Conference and Exhibition, 2011
Abstract Drilling lags behind other industries in the implementation of automation. One reason for this is the variability of drilling operations and uncertainty in knowing what is being drilled at any given time. A closed-loop system that continually monitors drilling parameters and drilling performance in real time and constantly ...

A novel vibration drilling tool used for reducing friction and improve the penetration rate of petroleum drilling

Journal of Petroleum Science and Engineering, 2018
A novel self-resonating oscillator which can be used for reducing the friction between drill-pipe and borehole wall and improving the rate of penetration is proposed.

Rate of Penetration of Phosphate into Muscle Cells

Acta Physiologica Scandinavica, 1940
Summary.Labelled sodium and labelled phosphate are injected simultaneously into the lymph sack of the frog and the distribution of the radioactive sodium and the radioactive phosphate between plasma and muscle of equal weights is determined. A constant partition ratio of the radioactive sodium is obtained after the lapse of about 20 minutes.

Influence of surface characteristics on the penetration rate of electrolytes into model cells for lithium ion batteries

Journal of Adhesion Science and Technology, 2019
Filling of cells with liquid electrolytes is the time-determining step in the production of lithium-ion batteries (LIBs). The influencing factors are not completely understood and need further research. The adhesion of the solid components, i.e.
