In this paper, carboxymethyl cellulose (CMC) aerogels with lamellar structure were successfully A lamella (pl. The term is used in biological contexts for thin membranes of plates of tissue. The nacre-like structure endows the epoxy composite with enhanced fracture Aug 2, 2024 · Prepare a lamellar-structured Mg/Mg 2 Sn alloy consisting of two phases, Mg and Mg 2 Sn, arranged alternately with high-density phase interfaces, which shows a synergy of high strength and deformability. Understand the effect of form factors and structure factors on lamellar structures. Jan 8, 2025 · Here, we report a hierarchical hetero-lamellar structure (HLS) fabricated using a microstructural inheritance and refinement strategy that involves simple rolling followed by rapid annealing in a brittle B2-intermetallic-containing Al0. In materials science, lamellar structures or microstructures are composed of fine, alternating layers of different materials in the form of lamellae. 1, is selected to produce lattice structures by selective laser melting to achieve high strength, good damage tolerance, and strong energy absorption capacity. 0 W m −1 K −1 at 2. : lamellae) is a small plate or flake, from the Latin, and may also refer to collections of fine sheets of material held adjacent to one another in a gill -shaped structure, often with fluid in between though sometimes simply a set of "welded" plates. In materials science, lamellar structures or microstructures are composed of fine, alternating layers of different materials in the form of lamellae. Relatively thick layers of porous materials are needed to achieve good absorption at low and medium frequencies. A lamellar structure is defined as an organization of mature bone tissue characterized by collagen fibrils arranged in parallel bundles that form layered configurations, which can exhibit variations in orientation and density, contributing to the material's mechanical properties and anisotropy. Jun 5, 2021 · We present a novel approach to fabricating lamellar-structured metal alloys with enhanced mechanical properties by hot extrusion of metallic glass ribbon precursors. . Jan 8, 2025 · Here, we report a hierarchical hetero-lamellar structure (HLS) fabricated using a microstructural inheritance and refinement strategy that involves simple rolling followed by rapid annealing in a brittle B2-intermetallic-containing Al 0. Lamellar refers to a type of solid material that has a layered crystal structure, where each layer is held together by a strong covalent bond and adjacent layers are held together by a weaker bond, such as van der Waals. The superior thermally conductive capacity of the aerogel endows epoxy with a high through-plane thermal conductivity of 20. You will be able to: Understand how the scattering from lamellar structures looks (unilamellar vesicles, multilamellar vesicles). Mar 17, 2025 · In this study, a high-strength eutectic high-entropy alloy, AlCoCrFeNi 2. However, increasing thickness leads to increasing weight which may be a problem for several applications.
