Effects of Mg on Microstructure and Solidification of a Hypereutectic Zn–8 wt.%Al Alloy
Advanced Engineering Materials, EarlyView.An appreciable set of results involving thermal data, microstructure, chemical composition, and microstructural growth laws is reported for ZnAlMg alloys. Such results demonstrate that ZnAlMg alloys have high potential for applications in automotive self‐lubricating components, batteries, and electrical systems.

The High Energy View of FR0 Radio Galaxies
Galaxies, 2019 A new class of low-power compact radio sources with limited jet structures, named FR 0, is emerging from recent radio-optical surveys. This abundant population of radio galaxies, five times more numerous than FR Is in the local Universe (z < 0.05 ...

Direct Imaging of a Toroidal Magnetic Field in the Inner Jet of NRAO 150
Galaxies, 2016 Most formation models and numerical simulations cause a helical magnetic field to form, accelerate and collimate jets in active galactic nuclei (AGN). For this reason, observational direct evidence for the existence of these helical magnetic fields is of

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies
Advanced Functional Materials, EarlyView.Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Coupling of Underexpanded Twin-Jets
, 2020 Aircraft jet engines produce thrust by exhausting a jet of high velocity gas. The jet produces a large portion of the overall aircraft noise once it leaves the engine and interacts with the surrounding air. This noise is enhanced if two jets (or engines)

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots
Advanced Functional Materials, EarlyView.This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

Chitin‐Derived Carbon‐Metal Functional Materials
Advanced Functional Materials, EarlyView.Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.
