Performance of LLBC-based rotor blade for low speed wind turbine
MATEC Web of Conferences, 2018 The development of wind turbine attracts more attention as a renewable energy that supports green technology. Layer Laminated Bamboo Composite (LLBC) is a bio-composite with bamboo base material which is abundant material and has a relatively lower price.

Bio‐Inspired Gradient Coatings Enhance the Leading Edge Erosion Resistance of Wind Blades
Advanced Science, EarlyView.Rain‐induced erosion of the wind turbine blade leading edge poses a critical challenge to maintenance and operation. Here, we propose a bio‐inspired approach for erosion protection utilising a platelet‐reinforced polyurethane coating with a graded through‐thickness architecture.

Determination of wind turbine far wake using actuator disk [PDF]
, 2014 The growth in size of wind turbines over the last years is significant. The rotor diameter becomes somehow comparable to atmospheric boundary layer at the land surface. In this case the assumption of uniform velocity of upcoming wind cannot be valid. The

Double Helix Structure for Stable Flexural Actuation in Soft Robotics
Advanced Intelligent Systems, EarlyView.This work introduces a double‐helical architecture for soft robotic actuators that enhances twisting resistance, increases output force, and minimizes undesired deformation. Actuators driven by shape‐memory alloy wires exhibit a roughly fivefold higher torsional/flexural stiffness ratio and 50% greater force output.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Efficient removal of liquid aerosols from compressed gas streams is essential in chemical and energy processes. Conventional separators relying on a single mechanism (inertial or centrifugal) struggle to capture both fine and coarse droplets simultaneously.
