Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture

Advanced Healthcare Materials, Volume 15, Issue 16, 24 April 2026.
This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Ultra‐Thin Soft Pneumatic Actuation for Minimally Invasive Neural Interfacing

Advanced Materials Technologies, Volume 11, Issue 7, 6 April 2026.
Parylene C is a common polymer in bioelectronics, favored for its biological and chemical inertness. However, this makes bonding layers of Parylene C together very challenging. Here it is a laser to selectively weld layers of Parylene C to create high‐pressure fluidic actuation devices.

Manufacturing of PP‐Based Composite Sandwich Panels via Simultaneous Foaming and Skin‐Core Bonding

Polymer Composites, Volume 47, Issue 3, Page 2349-2362, 10 February 2026.
One‐step CO2 physical foaming process for manufacturing thermoplastic sandwich panels: in‐situ expansion of a foaming‐grade PP core and fusion bonding with PP/glass fiber composite skins. ABSTRACT Sandwich panels are skin‐core‐skin structures commonly used in aerospace applications due to their high strength‐to‐weight ratio and flexural stiffness.

Predication of Kerf Width and Surface Roughness in Waterjet Cutting using Neural Networks

Journal of Physics: Conference Series, 2019
Abstract Abrasive waterjet cutting is one of the unconventional methods used to cut some of the difficult to cut materials. In certain materials this method has proved to give better results compared to the conventional methods. In this model the water jet cutting is done on hastelloy using the three parameters which are abrasive mass ...

Sharp Force Trauma and Chop Mark Identification Bias: Experimental Evidence on the Effects of Bone Morphology, Cortical Thickness, and Ax Material

International Journal of Osteoarchaeology, Volume 36, Issue 1, Page 88-100, January/February 2026.
ABSTRACT Sharp force trauma (SFT) is the main criterion used to identify chop mark butchery in zooarchaeology, yet its reliability as a diagnostic feature has not been systematically tested. Chop marks reflect both cutting and fracturing processes and exhibit characteristics of both sharp and blunt trauma.
