Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

Advanced Functional Materials, EarlyView.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

Development of a Drilling Simulator to Achieve Drilling Optimization

, 2023
In summary, drilling simulation, a set of physic-based models run through time or depth steps to mirror events in the drilling rig, is the backbone of all field testing of technologies or procedures. If a model has been validated using drilling simulation, the risk of wasted field trial is lowered significantly.
