Domain Wall Rebounds Driven by Competing Entropic and Spin‐Transfer Torques in Cylindrical Nanowires

Advanced Functional Materials, EarlyView.
Domain‐wall motion in cylindrical magnetic nanowires driven by nanosecond current pulses. Low current densities efficiently displace domain walls, whereas higher currents cause rebound at the wire ends. The effect results from the interplay between spin‐transfer torque and thermally induced processes, highlighting the role of thermal gradients in ...

Harnessing the Orientation of Columnar Discotic Liquid Crystals for Narrowband Blue Emission with Enhanced Out‐Coupling Efficiency Toward Improvement of SP‐OLEDs Performance

Advanced Functional Materials, EarlyView.
Solution‐processed OLEDs containing discotic liquid‐crystalline MR‐TADF emitters are reported. Supramolecular self‐assembly induces homeotropic columnar alignment, enforcing preferential horizontal orientation of the emitter transition dipole moment in spin‐coated films, which leads to an enhancement in the device light outcoupling efficiency while ...

Tissue Engineered Human Elastic Cartilage From Primary Auricular Chondrocytes for Ear Reconstruction

Advanced Functional Materials, EarlyView.
Despite over three decades of research, no tissue‐engineered solution for auricular reconstruction in microtia patients has reached clinical translation. The key challenge lies in generating functional elastic cartilage ex vivo. Here, we integrate synergistic cell‐biomaterial strategies to engineer auricular grafts with mechanical and histological ...

A Proposed Approach for Plastic Limit Determination Using the Drop-Cone Penetrometer Device

Journal of Engineering and Sustainable Development, 2008
The drop-cone method, in which a 30° cone of mass 80 g is allowed to penetrate into a soil sample at any moisture contents, was used to determine the plastic limit for more than 160 natural samples representing a wide range of soil type with different ...
