Fracturability Index for Optimal Well Placement and Fracture Positioning

, 2014
The early detection of "sweet spots" for oil/gas well site selection and fracturing in shale reservoirs is a challenge for many operators. Most of the time, unique parameters are utilized (i.e.

Mechanical Programming of PEGDA‐β‐CD Polyrotaxane‐Based Hydrogels via Host–Guest Molecular Recognition

Advanced Functional Materials, EarlyView.
A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...

Freeze‐Thaw Engineered Dual Conductivity Polymeric Binder Stabilizes Large‐Volume‐Change Lithium–Ion Battery Anodes

Advanced Functional Materials, EarlyView.
This work developed an all‐aqueous freeze‐thaw strategy to create a dual‐conductive PVA/P3KBT binder for high volume‐change lithium–ion battery anodes. The resulting binder system strengthens the electrode structure, supports ion and electron transport, and accommodates repeated volume changes, reducing cracking and improving long‐term cycling ...

Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials

Advanced Functional Materials, EarlyView.
Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...

Preferential Interfacial Engineering of Hydrogels via Interdigitated Nanoparticle Assembly

Advanced Functional Materials, EarlyView.
Robust surface functionalization of hydrogel surfaces is performed via interdigitated metal nanoparticle assembly, inducing strong affinity with the hydrogel matrix. The partially exposed nanoparticle domains act as interfacial nanobridges that mediate both chemical and physical bonding with diverse materials, including small molecules, fluorous ...
