Longer Acting Injectable: Continuous, Linear Release of a Progestin Contraceptive From an Oxidized Porous Silicon Host

open access: yesAdvanced Healthcare Materials, EarlyView.
Progestin drugs are loaded into a mesoporous silicon dioxide host by melt‐infiltration. Drugs that decompose at or close to their melting point can be loaded by the addition of cholesterol, which acts as a melting point suppressor. High mass loading of the drug is achieved, and dissolution of the composite is controlled by the nanoscale properties of ...

An In Situ Curing, Shear‐Responsive Biomaterial Designed for Durable Embolization of Microvasculature

open access: yesAdvanced Healthcare Materials, EarlyView.
NeoCast is a next‐generation, solvent‐free, non‐adhesive liquid embolic designed for indications where deep occlusion is desired (e.g., tumors and chronic subdural hematoma). This novel agent offers ideal embolic properties: injectability, controllability, excellent visibility, and biocompatibility.

Laboratory Study on Core Fracturing Simulations for Wellbore Strengthening

open access: yesGeofluids, 2019
The lost circulation in a formation is one of the most complicated problems that have existed in drilling engineering for a long time. The key to solving the loss of drilling fluid circulation is to improve the pressure-bearing capacity of the formation.

Effects of Drilling Fluid Rheological Properties on Drill Cuttings Transport [PDF]

open access: yes, 2010
During well drilling process, drill cuttings were produced. Drill fluid (or mud) has been used to remove the drill cuttings that are produced in the well by transporting it to the surface.
