Impact of the anisotropy of fracture toughness on the propagation of planar 3D hydraulic fracture

open access: yes
Sedimentary rocks often exhibit a transverse isotropy due to fine scale layering. We investigate the effect of the anisotropy of fracture toughness on the propagation of a planar 3D hydraulic fracture perpendicular to the isotropy plane: a configuration ...

From Agro‐Industrial Waste to Functional Packaging Using Antimicrobial and Mechanically Reinforced Starch Foams With Melon Seed and Rosemary

open access: yesJournal of Applied Polymer Science, EarlyView.
Agro‐industrial waste was upcycled into biodegradable starch foams reinforced with melon seed and rosemary flours, yielding sustainable food packaging with enhanced mechanical performance, selective antimicrobial activity, and rapid biodegradation. ABSTRACT The demand for sustainable alternatives to petroleum‐based packaging has promoted starch‐based ...

Duration of hydraulic fracture containment by tougher bounding layers

open access: yes
The vertical growth of engineered hydraulic fractures above the formation of interest, toward potentially environmentally sensitive layers, is a primary design constraint in hydraulic fracturing well stimulation.

Enabling Bioprocess Upscaling Prediction Through Hybrid Modelling and Transfer Learning Under Small‐Data Scenarios

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Accurate prediction of bioprocess scale‐up is critical for accelerating the deployment of novel and sustainable biomanufacturing systems. However, this remains challenging as multi‐scale data is expensive to generate and mechanistic understanding is often incomplete, leading upscaling decisions to rely heavily on empirical expertise.

Elucidating the Interplay Between Structure and Electrochemical Behavior in Lignin‐Based Polymer Electrolytes for Potassium Batteries

open access: yesBattery Energy, Volume 4, Issue 2, March 2025.
Three biobased membranes are synthesized by crosslinking oxidized Kraft lignin with poly(ethylene glycol) diglycidyl ether of increasing molecular weights. After incorporation of solvated potassium salts, potassium batteries including these biobased gel polymer electrolytes are able to deliver a maximum specific capacity at 0.05 A g−1 as high as 130 ...

Hydraulic Fracture in Highly Permeable Rock

open access: yes, 2019
Models of hydraulic fractures in conventional reservoirs assume that Carterâ s leak-off law â the leak-off rate is proportional to the inverse of the square root of the time elapsed since exposure to fracturing fluid â is applicable.

Buddy Wire–Augmented Intravascular Lithotripsy in Refractory Calcified Coronary Lesions: A Five‐Case Series

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Heavily calcified coronary lesions remain a major challenge in percutaneous coronary intervention (PCI), often limiting the effectiveness of intravascular lithotripsy (IVL). We report a five‐case series in which IVL failed to achieve adequate lesion modification but was successfully augmented by the addition of one or more buddy wires.
