Advanced Science, EarlyView.A CCM‐based architectural strategy is introduced for high‐temperature PEM fuel cells, enabling MPL‐free carbon paper gas diffusion layers via decal‐transfer processing. By co‐engineering the CCM, GDL, and a G‐foam flow field, oxygen transport is enhanced while phosphoric‐acid leakage is suppressed, resulting in high power density and stable operation ...

The Coracohumeral Ligament and Its Fascicles: An Anatomic Study
Journal of Functional Morphology and KinesiologyBackground: The coracohumeral ligament (CHL) is inserted in the coracoid process, from which it extends laterally and caudally, blending with the tendinous insertions of the subscapularis muscle and the supraspinatus muscle, with a third intermediate ...

On the exceptional damage-tolerance of gradient metallic materials [PDF]
, 2020 An experimental study is described on the fracture toughness and micro-mechanisms associated with the initiation and propagation of cracks in metallic nickel containing marked gradients in grain size, ranging from ∼30 nm to ∼4 μm.

Advanced Science, EarlyView.Hierarchical PP–LSR107–BaTiO3 nanocomposite films are fabricated by one‐step extrusion and stretching for roll‐to‐roll manufacture, combining high energy storage and processing flexibility. LSR107 surrounds BaTiO3‐rich regions, locating amorphous PP, decreasing defects, and introducing deep traps that homogenize the electric field and suppress charge ...

Automatic analysis of magnetic resonance (MR) sequences for the diagnosis of ligament lesions [PDF]
, 1999 To date the diagnosis of carpal instabilities due to ligament lesions relies upon a qualitative examination of the patient's wrist. This paper presents a novel system where sequences of magnetic resonance images (MRI) are automatically analysed to ...

Advanced Science, EarlyView.A quasi‐periodic Dart‐Kite (QDK) metastructure with a golden‐ratio‐constrained strong–weak bond network simultaneously enhances strength, toughness, and damage tolerance. Its distributed topology enables predictable, tailorable crack paths for precise fracture control and stable mechanics, demonstrating a high‐performance, controllable architecture ...

Sports Medicine and Arthroscopy Review, 2019 Posterior cruciate ligament injuries may occur as an isolated injury or in combination with other ligaments in the multiple-ligament injured knee. Caution must be exercised in chronic posterior cruciate ligament injuries since the MRI may demonstrate a normal-appearing posterior cruciate ligament even when there is significant laxity on clinical ...

Advanced Science, EarlyView.Current technologies for spinal cord optogenetic stimulation rely on external power sources and face reliability constraints in freely behaving animals. Here, a fully implantable, battery‐powered optoelectronic device is introduced, enabling operation in any selected environment with wireless recharging for months‐long stimulation.
