Remove Detrimental Solids from Recycled Old Drilling Fluids Using Oil-Based Drilling Fluid Flocculants

open access: yesZuanjingye yu wanjingye
Recycled old oil-based drilling fluids generally contain high concentrations of detrimental solids which result in performance deterioration of the drilling fluids. These detrimental solids can be removed through flocculation. In this study, an oil-based

Assessment of zonal isolation risk to changes in design parameters [PDF]

open access: yes, 2017
The Well Containment Screening Tool (WCST) focuses on well integrity evaluation after well control incident. The WCST favors a greater wall thickness and, hence, a narrower cementing annulus, potentially increasing the risk of cement loss.

Advanced Separators for Liquid and Quasi‐Solid Lithium Rechargeable Batteries: Design and Development

open access: yesAdvanced Materials, EarlyView.
This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...

A Tac1‐Expressing Brainstem Pathway Underlies the Pathogenesis of Trigeminal Neuralgia

open access: yesAdvanced Science, EarlyView.
A critical TG‐Sp5CTac1‐PBNTac1 pathway drives trigeminal neuropathic pain (TNP). Tac1‐expressing parabrachial nucleus (PBNTac1) neurons exhibit heightened responses to innocuous stimuli in TNP, and chemogenetic inhibition of these neurons effectively prevents TNP development.
