Fabrication of a Stable, Low‐Cost, Patient‐Specific, Brain Phantom with Ventricles for Ultrasound Imaging

Advanced Engineering Materials, EarlyView.
Patient‐specific brain phantoms can replace animal trials, aid presurgical training, and enable in silico disease research on cerebrospinal fluid and ventricles. This study presents a method to create ventricular brain phantoms from three‐dimensional magnetic resonance images brain scans, resulting in durable, tunable, reproducible models that mimic ...

Cardiac repolarization abnormalities and neurally mediated syncope: overlooked aspects in the diagnosis of pheochromocytoma

International Journal of Arrhythmia
Background Pheochromocytoma is a rare catecholamine-producing tumour originating from adrenal chromaffin cells. Classic clinical presentation includes headache, diaphoresis and palpitation.

Multimaterial Approach to Improve the Mechanical Properties of a Novel Modified Auxetic Reentrant Honeycomb Structure

Advanced Engineering Materials, EarlyView.
A multimaterial approach is introduced to improve upon auxetic structures by combining two different polymers into the same reentrant honeycomb structure via additive manufacturing. The deformation behavior as well as the resulting Poisson's ratio are thereby improved significantly.

Vacuum‐Formed Composites Based on a Polyolefin and a High Content of Biomass‐Waste Fillers

Advanced Engineering Materials, EarlyView.
It is shown here that by the use of a very ductile polymer matrix, it is possible to vacuum‐form products that contain up to 25% of hard biofillers with still ductile properties. The results are promising and opens up for the use of engineered biocomposites derived from industrial side‐stream biofillers in vacuum‐formed products. A strategy to increase

Antimicrobial Titanium–Copper Alloys: The Role of Microstructure in Arc‐Melted Compositions

Advanced Engineering Materials, EarlyView.
Copper‐containing titanium alloys show promise in combating orthopedic implant infections. This study explores the influence of heat treatment on Ti‐11.5Cu and Ti‐33Cu alloys, revealing that larger Ti2Cu precipitates (≈5 μm) enhance antimicrobial efficacy through increased surface contact. Results suggest contact sterilization is the primary mechanism,

High‐Temperature Oxidation of the CrFeNi Medium‐Entropy Alloy

Advanced Engineering Materials, EarlyView.
The oxidation behavior of equiatomic CrFeNi MEA is a key issue that determines this material's suitability for high‐temperature application. The understanding of long‐term behavior is even more crucial than short‐term corrosion effects. The alloy is exposed to synthetic air at 1000, 1050, and 1100 °C for 24, 100, and 1000 h and systematically compared ...
