Development of an Ultralight with a Ducted Fan

Acta Polytechnica, 2012
This paper introduces the UL-39 project, an ultralight aircraft with a ducted fan, and some of the problems that have arisen in the course of its development. Several problems with the design of a non-traditional aircraft of this kind are mentioned, e.g.

Biologically‐Inspired Melt Electrowriting for the Generation of Highly Biomimetic Functional Myocardium

Advanced Functional Materials, EarlyView.
In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.

Vivid Structural Coloration in Transparent MXene‐Cellulose Nanocrystals Composite Films

Advanced Functional Materials, EarlyView.
Vivid structural coloration in reflectance and high transparency in transmittance modes are observed in biopolymer‐layered composite films. The ultrathin multilayered structures have unique optical appearance, near‐infrared bandgap, and strong optical reflection caused by alternating MXene and cellulose nanocrystals layers with high refractive index ...

Inertial measurement unit-based real-time feedback gait immediately changes gait parameters in older inpatients: a pilot study

Frontiers in Physiology
The effect of gait feedback training for older people remains unclear, and such training methods have not been adapted in clinical settings. This study aimed to examine whether inertial measurement unit (IMU)-based real-time feedback gait for older ...

Advances in Radiative Heat Transfer: Bridging Far‐Field Fundamentals and Emerging Near‐Field Innovations

Advanced Functional Materials, EarlyView.
This review synthesizes the evolution of radiative heat transfer, emphasizing the transition from far‐field to near‐field regimes. Traditional frameworks, such as Planck's law, are revisited alongside modern innovations like fluctuational electrodynamics. Applications span nanoscale thermal management, energy harvesting, and thermophotovoltaic systems.
