Biohybrid Crawling Robot With Spiral‐Spring Backbone and Inclined Legs for Enhanced Locomotion

Advanced Materials, EarlyView.
We present a biohybrid crawling robot integrating a muscle ring with a flexible skeleton combining two complementary structural elements. The spiral‐spring backbone enables large‐amplitude bending without compromising axial stability, while outward‐inclined legs with unequal front–rear lengths effectively convert deformation into directional strides ...

A Single‐Solvent Acetone Strategy for Surface Enhancement and Robust Bonding in PMMA Microfluidic Devices

Advanced Materials Interfaces, EarlyView.
A single‐solvent acetone strategy simultaneously restores laser‐ablated PMMA surfaces and enables high‐strength bonding for microfluidic device fabrication. The process produces smooth, optically clear channels, achieves bonding strengths up to 27.3 MPa, and forms leak‐free devices within 25 min, providing a rapid and accessible route to robust PMMA ...

Temporary immersion system : A new concept for use liquid medium in mass propagation

, 2005
Mass propagation of plants by tissue culture is labour intensive and costly. Gelling agents have many drawbacks: they are not inert medium components and do not enable easy automation for commercial mass propagation.
