Lines of Flight: Everyday Resistance along England’s Backbone [PDF]

open access: yes, 2009
The visual and the cultural impact of ‘social industry’ has made a permanent impression on the landscape and on individual minds, whether for ill or for good, particularly in the Peak and Pennines region of northern England.

Precursor Mineral Phases of Forming Mollusk Shell Nacre: A Study of Hydrated Samples

open access: yesAdvanced Functional Materials, EarlyView.
Mineral, organic phase, and water are the essential components in mollusk shell nacre formation. Their interplay is not well understood, because the hydrated material is difficult to observe at high resolution, under close to native conditions. Forming nacre is studied using environmental and cryo‐electron microscopy and hydrated ACC phases, together ...

Atomically Revealing Bulk Point Defect Dynamics in Hydrogen‐Driven γ‐Fe2O3 → Fe3O4 → FeO Transformation

open access: yesAdvanced Functional Materials, EarlyView.
In situ TEM uncovers the atomic‐scale mechanisms underlying hydrogen‐driven γ‐Fe2O3→Fe3O4→FeO reduction. In γ‐Fe2O3, oxygen vacancies cluster around intrinsic Fe vacancies, leading to nanopore formation, whereas in Fe3O4, vacancy aggregation is suppressed, preserving a dense structure.

Mechanical Response of Soft Rock Roadways in Deep Coal Mines Under Tectonic Stress and Surrounding Rock Control Measures

open access: yesApplied Sciences
This study focuses on how rocks respond mechanically and how to keep them stable when soft rock roadways are under deep tectonic stress. It does this through a combination of theoretical analysis, numerical simulations, and field applications. We created

OCTOID: A Soft Robotic System Featuring Programmable Shape Morphing and Dynamic Structural Coloration

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by octopuses, actuating legs based on soft materials are fabricated with programmed chiroptical properties and mechanical behaviors to achieve dynamic color modulation and reversible shape morphing, and these legs are developed into a modular OCTOID system.

A Single‐Metal‐Doped Nanoplatform for Ferroptosis‐Driven cGAS‐STING Pathway Activation in Hepatocellular Carcinoma Immunotherapy

open access: yesAdvanced Functional Materials, EarlyView.
The cGAS‐STING pathway boosts HCC antitumor immunity but lacks specific activation. Nanoplatform ZMRPF induces HCC ferroptosis via lipid ROS, releasing mtDNA. It synergizes with ZMRPF‐released Mn2⁺ to activate cGAS‐STING, amplifies antigen‐presenting cell activity, reverses HCC immunosuppression, and enables robust systemic antitumor immunity ...

Monitoring-Based Assessment of Deformation Behavior and Support Effectiveness in a Deep Hard Rock Drift

open access: yesApplied Sciences
To reveal the real deformation behavior and control mechanism of surrounding rock in hard rock drifts under deep high-stress conditions, a systematic study was conducted involving engineering geological investigation, in situ monitoring of surrounding ...

Preliminary Canopy Removal Experiments in Algal Dominated Communities Low on the Shore and in the Shallow Subtidal on the Isle of Man [PDF]

open access: yes, 1985
The algal dominated communities immediately above and below the low-water spring level on a moderately exposed Manx shore were investigated by canopy removal experiments. Fucus serratus, Laminaria digitata and L. hyperborea were removed.

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...
