Highly Entangled Bottlebrush Polymer Networks

open access: yesAdvanced Materials, EarlyView.
Bottlebrush polymers are difficult to entangle, enabling ultrasoft yet brittle networks. We report highly entangled bottlebrush elastomers that remain ultrasoft (∼1 kPa) yet stretch to ∼1800% and exhibit exceptional fatigue resistance. Their intrinsic fatigue strength—fatigue threshold normalized by modulus—surpasses that of highly entangled linear ...

A Porous Interfacial Photothermal Layer of Fused Core–Shell Carbon‐Polymer Nanospheres for Directional Salt Crystallization and Zero‐Liquid‐Discharge

open access: yesAdvanced Materials, EarlyView.
A hierarchical hydrogel evaporator with a thin, porous photothermal layer of fused core–shell carbon‐polymer nanospheres enables ultrafast interfacial solar evaporation with minimized heat loss and sufficient water supply. Directional advection‐dominated brine transport, coupled with Marangoni‐driven interfacial flow, drives salt away from the active ...

Combination of 3D and 2D Small and Wide Angle X‐Ray Scattering Imaging Reveals Diminished Bone Quality in the Superior Human Femoral Neck Cortex

open access: yesAdvanced Materials, EarlyView.
Combined 2D and 3D X‐ray scattering imaging is used to analyse nanostructural properties in the inferior and superior cortex of 78 human femoral necks from 44 donors. The methodology allows for increased interpretation of nanostructure in a statistically relevant dataset, revealing nanostructural differences in anatomical locations critical to clinical

Evolution‐Driven Bio‐Composite Aerogels for Self‐Adaptive Thermal Regulation and Energy Storage

open access: yesAdvanced Materials, EarlyView.
Inspired by nature's multiphase integration, a single chitosan (CTS)–metal chloride (MCl3) coordination precursor is engineered to enable sequential material and functional evolution. The resulting metal ion‐coordinated chitosan (CTS–M) aerogels exhibit humidity‐adaptive thermal insulation for battery safety, while carbonization yields conductive ...

Microfacies control on geomechanical properties of unconventional carbonate reservoirs: insights from a middle jurassic outcrop analogue in Saudi Arabia

open access: yesJournal of Petroleum Exploration and Production Technology
The interplay between depositional and diagenetic processes controls the distribution of geomechanical properties in carbonate rocks. Understanding the distribution of geomechanical properties in rocks is crucial for analyzing the behavior of ...

An Ion‐Based Strategy Toward Synergistic Surface Functionalization Combining the Osteogenic Properties and NIR‐Mediated Antibacterial Activity of PEEK

open access: yesAdvanced Materials, EarlyView.
A multifunctional bioactive PEEK‐based implant (Mn@p/MBG‐SPEEK) is engineered to combat implant‐associated infections while promoting osteogenesis. The hybrid surface activates PI3K/Akt/mTOR and AP‐1 signaling pathways for osteogenic differentiation, while Mn coordination induces electronic coupling that narrows the HOMO‐LUMO energy gap and enhances ...

Meniscus‐Guided Interfacial Ring‐by‐Ring Assembly for In Situ Fabrication of Tubular Hydrogels

open access: yesAdvanced Materials, EarlyView.
A tubular hydrogel fabrication method leveraging the meniscus effect at the oil‐water interface is presented. UV irradiation across the concave surface of the photocurable hydrogel precursor induces the formation of ring‐like hydrogel structures. Sequential ring‐by‐ring assembly within microchannels enables the construction of arteriole‐scale hydrogel ...
