Liquid Crystalline Elastomers in Soft Robotics: Assessing Promise and Limitations

Advanced Robotics Research, EarlyView.
Liquid crystalline elastomers (LCEs) are programmable soft materials that undergo large, anisotropic deformation in response to external stimuli. Their molecular alignment encodes directional actuation in a monolithic structure, making them long‐standing candidates for soft robotic systems.

Enhancing the Ultrasonic Welding of Wood Using 3D Printed Lignin Energy Directors

Advanced Science, EarlyView.
Sustainable manufacturing for lightweight structures using ecofriendly materials will be key to reducing material consumption and lowering carbon footprints. Here, an approach is presented to weld wood using ultrasonic vibrations with material at the joint interface to direct energy.

Buckling Loads and Effective Length Factor for Non-Prismatic Columns

Journal of Engineering, 2017
Based on a finite element analysis using Matlab coding, eigenvalue problem has been formulated and solved for the buckling analysis of non-prismatic columns. Different numbers of elements per column length have been used to assess the rate of convergence

Edible Pneumatic Battery for Sustained and Repeated Robot Actuation

Advanced Science, EarlyView.
This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

DQ thermal buckling analysis of embedded curved carbon nanotubes based on nonlocal elasticity theory

Latin American Journal of Solids and Structures
To investigate the thermal buckling of curved carbon nanotubes (CCNTs) embedded in an elastic medium, nonlocal elasticity theory is employed in combination with the theory of thin curved beams.

Degradable and Recyclable 3D‐Printed Pheromones Delivery System Reinforced by Metal Coordination Cross‐Linking for Efficient Pest Trapping

Advanced Science, EarlyView.
This study presents a 3D‐printed carrier for the slow release of insect pheromones. Reinforced by lignosulfonate and Fe³⁺ coordination in a cellulose acetate matrix, it enables sustained release for up to six weeks with remarkable trapping efficacy. Featuring soil degradability and recyclable re‐printing capability, this carrier provides a sustainable ...
