Mechanism of enhanced coalbed methane desorption regulated by fracturing fluid imbibition in deep coal seams

Petroleum Exploration and Development
Low-salinity fracturing fluids tend to induce ion migration, alter wettability, and cause fluctuations in gas desorption efficiency when penetrating deep coal seams. Taking the No.

Scaling of Imbibition Front Dynamics in Heterogeneous Porous Media

Geophysical Research Letters, 2020
We report a quantitative study on the dynamics of countercurrent imbibition in fractured rock samples with the application of CO2 geosequestration, as the rock matrix is saturated with CO2 and brine exists in the adjacent microfracture. Direct pore‐scale

Mechanistic Understanding and Three‐Dimensional Tuning of Fluid Imbibition in Silica‐Coated Cotton Linter Paper Sheets [PDF]

, 2022
Paper‐based microfluidic devices are used in point of care diagnostic, sensor technology or lab‐on‐a‐chip devices. Although a number of studies has been reported, only relatively few paper‐based diagnostic tools are available on the market.

Avalanches in strong imbibition

Communications Physics, 2022
Drainage and imbibition in porous media are two opposite fluid displacement scenarios with remarkably different underlying mechanisms. Here, the authors demonstrate that strong imbibition in porous media shows features of self-organized criticality ...

Abnormal Phenomena and Mathematical Model of Fluid Imbibition in a Capillary Tube

Energies, 2022
At present, the imbibition behavior in tight rocks has been attracted increasing attention since spontaneous imbibition plays an important role in unconventional oil and gas development, such as increasing swept area and enhancing recovery rate. However, it is difficult to describe the imbibition behavior through imbibition experiment using tight rock ...

Biphasic Co‐Delivery of Curcumin and 5‐FU using 3D‐Printed Dissolving Microneedles for Skin Cancer Therapy

Advanced Healthcare Materials, EarlyView.
Using pixel‐aware digital light processing, the authors created high‐resolution, dissolvable microneedles from a PEGDA/VP matrix. These microneedles encapsulate curcumin and 5‐fluorouracil and dissolve in the skin, co‐delivering drugs directly to tumours.
