Experimental Simulation of Proppant Migration for Slick Water With Variable Viscosity During Fracturing

open access: yesGeofluids
The migration law of proppants in slick water during fracturing is of great significance for field fracturing. A large-scale visualized experimental device was utilized to test sand patterns for varying injection parameter combinations, and sensitivity ...

Preparation and Characterization of Hydrophobic-Associated Microspheres for Deep Profile Control in Offshore Oilfields

open access: yesInternational Journal of Polymer Science, 2018
Microspheres have excellent sealing performances such as injectivity, bridging-off, deep migration, and deformation performances, but their plugging effects are limited by the fast swelling rate and poor viscoelasticity.

Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy

open access: yesAdvanced Functional Materials, EarlyView.
This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.
