A Stretchable, Mechanically‐Interlocked Polyrotaxane Hydrogel for Wearable Motion and Electrophysiological Monitoring

Advanced Science, EarlyView.
A mechanically interlocked polyrotaxane hydrogel integrates sliding macrocycles within a covalent network, yielding skin‑like softness, high stretchability, robust adhesion, and stable ionic conductivity. This multifunctional interface enables simultaneous high‑fidelity monitoring of human motion and epidermal electrophysiological signals (ECG/EMG ...

Cotton Recruits Soil‐Derived Delftia tsuruhatensis to Suppress Aphid Detoxification Via Salicylic Acid‐Mediated Defense

Advanced Science, EarlyView.
This study systematically reveals a complex interactive network involving plants, microbes, and insects, elucidating the ecological and molecular mechanisms by which cotton enhances its resistance to aphids through the active recruitment of the beneficial soil bacterium Delftia tsuruhatensis.

Severe Plastic Deformation

2020
This chapter presents the production of light alloys (Ti-Mg) by severe plastic deformation. Alloys with different Mg content were synthesized by high-pressure torsion straining, technique that allows to obtain ultrafine-grained materials in both equilibrium and nonequilibrium, changing the chemical, thermodynamic, and mechanical properties of the ...

Severe Plastic Deformation - A Review

Materials Today: Proceedings, 2018
Abstract Severe plastic deformation is one of the methods widely used for producing a fine-grained structure throughout the volume. Different SPD methods have been used for producing a fine-grained and ultra-fine grained structure which effectively alters the microstructure and in turn improve the properties.

Severe Plastic Deformation of Steels

BHM Berg- und Hüttenmännische Monatshefte, 2008
In order to demonstrate the structural changes in steels during severe plastic deformation (SPD), Armco iron, a ferritic steel P800 and a pearlitic rail steel S900A are subjected to a high pressure torsion (HPT) deformation process. The microstructural evolution, the changes in microhardness and the flow stress behaviour are investigated.

The Role of Hydrostatic Pressure in Severe Plastic Deformation

Advanced Engineering Materials, 2003
AbstractThe contribution presents several experimental examples which show that the presence of an enhanced hydrostatic pressure—as compared to conventional large deformation modes—is one of the main features of severe plastic deformation (SPD). At the example of systematic high pressure torsion experiments with Cu at room temperature, strength ...

Paradoxes of Severe Plastic Deformation

Advanced Engineering Materials, 2003
AbstractSevere plastic deformation (SPD) can lead to emergence of microstructural features and properties in materials which are fundamentally different from the ones well known for conventional cold deformation. In particular, the instances of unusual phase transformations resulting in development of highly metastable states associated with formation ...

Severe Plastic Deformation of Amorphous Alloys

Materials Science Forum, 2008
The structure and mechanical properties of amorphous alloy Ni44Fe29Co15Si2B10 after severe plastic deformation (SPD) in Bridgman chamber at the different temperatures (77 and 298 K) have been studied. It is shown that the early stages of the SPD of amorphous alloy cause a noticeable decrease in microhardness HV and significant changes in the physical ...
