A research agenda for academic petroleum engineering programs

open access: yes, 1990
The development of a research agenda should be a direct way of portraying the scope of petroleum engineering, of identifying the critical technological issues faced by the profession,of elucidating the gaps between the existing research resources and the

Precision Lignocellulosic Biorefinery: Process Regulation From Corn Stover to Products

open access: yesAdvanced Science, EarlyView.
This study presents a precision biorefinery framework that transforms corn stover into high‐value bioproducts through whole‐process regulation. Mechanical fractionation separates feedstock into parenchyma‐rich short fibers and vascular‐bundle‐dominant long fibers.

A Viscous DES‐AAV‐Foxo1 Delivery System With High Transfection Efficiency for the Treatment of Corneal Endothelial Dysfunction by Restoring Mitochondria‐ER Contacts

open access: yesAdvanced Science, EarlyView.
High glucose triggers corneal endothelial dysfunction by impairing FOXO1‐mediated ITPR1 transcription, leading to disrupted mitochondria‐associated membrane (MAM) integrity and defective ER‐to‐mitochondria Ca2+ transfer. This study develops an innovative viscous DES‐AAV‐Foxo1 delivery system with enhanced transfection efficiency. This non‐invasive gene

Sulphur isotope abundances in petroleum and associated materials

open access: yes, 1958
journal articleA study has been made of the sulphur isotope ratios for petroleum from many different oil fields in the United States and Canada. The S34/S32 ratio for petroleum varies by about 4.5 per cent as compared with a total spread of about 9 per ...

A New Customizable Surfactant LLPS Strategy for Sustainable and Highly Efficient Radioactive Metal Ion Separation

open access: yesAdvanced Science, EarlyView.
A diluent‐free, customizable liquid–liquid phase separation (LLPS) platform enables highly efficient radioactive metal ion extraction and stripping. By encapsulating hydrophobic extractants into an ionic surfactant‐rich condensed phase, this LLPS system leverages synergistic electrostatic and coordination interactions.

Sticky Yet Slippery: Molecular Ordering Reconciles Bubble‐Surface Affinity With Ultralow Friction at the Nanoscale

open access: yesAdvanced Science, EarlyView.
By engineering the molecular order and thickness of PDMS layers, we reconcile the stickiness and slipperiness during bubble transport. AFM measurements and MD simulations further reveal how these nanoscale architectures tune hydrophobic interaction FHB and friction force f.
