Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

Advanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

Engineering Aging: Approaches to Model and Deconstruct Biological Complexity

Advanced Materials, EarlyView.
The macro‐experiences of aging are the result of an accumulation of micro‐changes that occur over time. Abstract The disparity between the global increase in life expectancy and the steady decline in health outcomes with age has been a major driver for developing new ways to research aging.

Disruption of Sulfur Metabolism and Redox Homeostasis in Staphylococcus aureus Using Mechanically Robust Antibiofilm Ti‐Bi Alloys

Advanced Materials Interfaces, EarlyView.
Titanium (Ti) and bismuth (Bi) are selected as alloying elements for the preparation of the Ti‐Bi binary alloy system. Biofilm formation is found to be inhibited by bismuth through the disruption of sulfur metabolism and redox homeostasis, as well as through the direct downregulation of biofilm‐associated proteins.

Development of a quantitative assessment for abnormal flexor synergy index in patients with stroke: a validity and responsiveness study

Journal of NeuroEngineering and Rehabilitation
Background Arm-lifting movements (shoulder flexion) are essential for upper extremity rehabilitation after a stroke. Abnormal flexor synergy (elbow flexion) is frequently observed during shoulder flexion, impeding functional improvement.

4D Bioprinted Self‐Folding Scaffolds Enhance Cartilage Formation in the Engineering of Trachea

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A bilayer self‐folding scaffold, triggerable by humidity, is fabricated via 4D bioprinting for trachea engineering. An analytical model is derived to predict its radius of curvature, enabling its scalability. Cartilage progenitor cells seeded on the scaffold perceive scaffold final curvature and react to it, by enhancing the upregulation of pro ...

Event‐Driven Elongation Monitor for Soft Devices Using a Deformation‐Activated Piezoconductive Switch

Advanced Materials Technologies, EarlyView.
A stretchable, event‐driven strain sensor with low energy consumption is developed using positive piezoconductive composites. These composites remain insulative when relaxed, while they become conductive when stretched. Their electrical characteristics are modifiable by the nickel's weight ratio and cross‐sectional geometry. Strain‐induced switching is

Isoperimetric Partitioning: A New Algorithm for Graph Partitioning [PDF]

, 2003
Temporal structure is skilled, fluent action exists at several nested levels. At the largest scale considered here, short sequences of actions that are planned collectively in prefronatal cortex appear to be queued for performance by a cyclic competitive
