Dual‐Functional Ingestible Passive Capsules for High‐Throughput Intestinal Sampling with Sealed Containment and Targeted Drug Delivery

Advanced Robotics Research, EarlyView.
To address challenges in high‐throughput intestinal sampling with sealed containment and target drug delivery, we developed a dual‐functional ingestible passive capsule with a dual‐triggered control system based on pH‐response and mechanical actuation.

A Superlubricated Magnetically Steerable Microcatheter with Integrated Optical and Fluidic Channels

Advanced Robotics Research, EarlyView.
A magnetically steerable microcatheter with integrated optical and fluidic channels is developed for multifunctional navigation in tortuous anatomical environments. A surface‐grafted hydrogel coating enables low‐friction actuation. The device demonstrates stable light and fluid delivery during magnetic manipulation, offering a compact platform for ...

Modifying Glucose Metabolism Reverses Memory Defects of Alzheimer's Disease Model at Late Stages

Advanced Science, EarlyView.
Using spatial transcriptomics, we show that ferul enanthate (SL‐ZF‐01) reverses episodic‐like memory deficits in aged, but not young, Alzheimer’s disease (AD) mice. SL restores glucose metabolism and Glucose Transporter 1/3 expression via an ‘Aging‐AD‐Rescue’ pattern, rescuing deficits seen in aged AD mice.

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 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.

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.
