New approach to evaluate the equivalent circulating density (ECD) using artificial intelligence techniques

open access: yesJournal of Petroleum Exploration and Production Technology, 2018
The equivalent circulation density (ECD) is a very important parameter in drilling high-pressure high-temperature and deepwater wells. ECD is a key parameter during drilling through formations where the margin between the pore pressure and the fracture ...

Nanofillers Reinforcing Biopolymer Composites for Sustainable Food Packaging Applications: A State‐of‐the‐Art Review

open access: yesAdvanced Functional Materials, EarlyView.
Biopolymers are sustainable, biodegradable alternatives to petroleum‐based plastics for food packaging. Its adoption is often limited by poor mechanical strength, barrier properties, and improved thermal stability through the incorporation of nanofillers.

Self‐supportive Three‐Way Photoelectrochemical System Achieving Uranium Recycling, Organic Oxidation, and Electricity Generation in Complex Waters

open access: yesAdvanced Functional Materials, EarlyView.
A self‐sustaining solar photoelectrochemical cell (SS‐PEC) is developed to recover uranium from aqueous UO22+ with concurrent organic oxidation and electricity production. The monolithical photoanode directly captures electrons from organic compounds, leading to the oxidation of organic compounds and the decomposition of uranium‐organic complexes ...

Oxidation consolidation characteristics of chromite pellets during the roasting process

open access: yes工程科学学报, 2016
The roasting consolidation characteristics of chromite pellets were systematically studied in this paper. The results show that preheating time has little effect on the compressive strength of preheating chromite pellets. Under the appropriate preheating
