Fine lamellae solve this problem by shortening the diffusion distance between phases, but their high surface energy makes them unstable and prone to break up when annealing allows diffusion to progress. A deeper eutectic or more rapid cooling will result in finer lamellae; as the size of an individual lamellum approaches zero, the system will ...
Lamella, in cell biology, is also used to describe the leading edge of a motile cell, of which the lamellipodia is the most forward portion. [5] The lipid bilayer core of biological membranes is also called lamellar phase. [6] Thus, each bilayer of multilamellar liposomes and wall of a unilamellar liposome is also referred to as a lamella.
Lamellae can also describe the layers of atoms in the crystal lattices of materials such as metals. In surface anatomy, a lamella is a thin plate-like structure, often one amongst many lamellae very close to one another, with open space between. In chemical engineering, the term is used for devices such as filters and heat exchangers.
The lamellae vibrate within a frame or hoop 121.1 Clack idiophones or Cricri - The lamella is carved in the surface of a fruit shell, which serves as resonator. [6] Also known as galip nut snapper. [7] 121.2 Guimbardes and jaw harps - The lamella is mounted in a rod- or plaque-shaped frame and depends on the player's mouth cavity for resonance.
Lamella of osteon, the concentric circles around the central Haversian canals; Lamella (cell biology): (i) part of a chloroplast (thin extension of thylakoid joining different grana) (ii) the leading edge of motile cells, containing the lamellipodia; Lamella, a group of land crabs in the family Gecarcinucidae
Lamellae on a gecko's foot. In surface anatomy , a lamella is a thin plate-like structure, often one amongst many lamellae very close to one another, with open space between. Aside from respiratory organs, they appear in other biological roles including filter feeding and the traction surfaces of geckos .
"Sympathetic" lamella rotation: A lamella is able to rotate away from the tensile direction if it is sandwiched between two lamellae that are reorienting themselves towards the tensile direction. This can happen if the bonding between these lamellae is high. [9] Ψ refers to the angle between the tensile axis and the collagen fibril.
One example of how lamellar armour is laced together. Lamellar armour consists of small platelets known as "lamellae" or "lames", which are punched and laced together, typically in horizontal rows. Lamellae can be made of metal, leather cuir bouilli, horn, stone, bone or more exotic substances. Metal lamellae may be lacquered to resist ...
