Ultrasonic Rainbow: A Meta‐Transducer for Frequency‐Selective Elastic Wave Control via Dithering‐Based Wavenumber Tuning

Advanced Intelligent Systems, EarlyView.
A piezoelectric meta‐transducer generates an ultrasonic rainbow, steering guided elastic waves to different angles according to frequency. A dithering‐based binary electrode design enables a closer realization of the target wavenumber filter, improving directional purity and suppressing unwanted lobes. Numerical and experimental validation demonstrates

Pre‐Curved Everting Robots With Embedded Steering Intelligence Fabricated by CO2 Laser Welding

Advanced Intelligent Systems, EarlyView.
Design and experimental demonstration of a laser welded growing robot for anatomically guided navigation. The robot follows an aortic arch phantom entering the branchiocephalic branch through steering by design. The figure shows the physical phantom setup, CAD defined weld geometry and full robot eversion.

Sustainable Palm Oil Extraction and Trends in the Use of Green Technologies: State‐of‐the‐Art and Future Directions

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Palm oil, which is extracted from the mesocarp of the fruit of the Elaeis guineensis Jacq. palm tree, is the most widely produced vegetable oil in the world. The extraction of this substance typically utilizes the conventional pressing method, a technique that is advantageous due to its low operating cost and simplified process.

Influence of Fat Oil Binding Capacity on Shelf‐Life and Consumer Acceptance of a Chocolate‐Based Model System

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In chocolate‐coated products, oil migration can lead to chocolate softening and discoloration, filling hardening, and reduced consumer acceptance. This study examined three fats (soy‐, palm‐, and palm‐kernel (PK) based), crystallized under different conditions (cooling rate and high intensity ultrasound (HIU)) with differing oil binding ...

Thermal Black‐Infused Polyurethane Rigid Foams: Novel Formulations Toward Higher‐Performance and More Sustainable Insulation

Journal of Applied Polymer Science, EarlyView.
Thermal black improves polyurethane foam structure and stability. It helps the foam rise smoothly while promoting the formation of smaller, more uniform cells. The foam keeps its strength and insulation performance while reducing shrinkage. Its clean production and easy processing make it a sustainable, cost‐effective option for high‐performance ...

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

The Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Effects of oropharyngeal neuromuscular stimulation on the volumetric enlarged and reduced tongue base in minipigs

The Anatomical Record, EarlyView.
Abstract Hypoglossal nerve or tongue protruding muscle stimulation is a current treatment option for obstructive sleep apnea. Thus, the present study analyzed 3D deformations of the volumetric enlarged and reduced tongue base upon oropharyngeal neuromuscular stimulation.
