Fin geometry and pitch length optimization for forced convection in tubes a numerical study
Journal of Thermal EngineeringMany applications require smaller, faster, and more powerful electronic devices, leading to excess heat that needs to be removed from the system. Micro-finned tubes are a preferred method to increase the heat-transfer performance of cooling systems ...

Interaction between natural and forced convections at a sphere in a laminar flow regime
, 1988 The authors deal with the formulation and solution of a boundary value problem describing the influence of natural convection on forced convection during diffusion to a sphere in a laminar flow regime, the orientation of the natural convection being ...

Angled Nozzle Aerosol Jet Printing to Streamline Conformal Patterning of Electronics
Advanced Materials Technologies, EarlyView.A modular, angled aerosol jet printhead is demonstrated to streamline patterning on nonplanar surfaces, including 90° step edges and confined internal geometries. A detailed analysis of gravitational settling for a sheathed aerosol flow and deconvolution of oblique deposition and gravitational effects supports the versatility of this approach for ...

A Fully Lithography‐Free Fabrication Strategy for Organic Electrochemical Transistors
Advanced Materials Technologies, EarlyView.A fully lithography‐free fabrication strategy for organic electrochemical transistors (OECTs) is developed, eliminating the need for photolithography and other cleanroom‐based processes. By combining a laser‐cut polymer mask with a dual‐layer tape process, the proposed strategy enables simple and accessible fabrication, facilitating rapid OECT ...

Advanced Robotics Research, EarlyView.This article presents dielectric elastomer switch (DES) materials, based on composite thin films. Alignment of graphite flakes due to their physical confinement within the thin films lead to much stronger piezoresistive responses than bulk composites, while their durability exceeds that of conventional liquid‐based DES materials.

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.

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine
Advanced Robotics Research, EarlyView.This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.
