  2. Spherical cap - Wikipedia

    en.wikipedia.org/wiki/Spherical_cap

    In geometry, a spherical cap or spherical dome is a portion of a sphere or of a ball cut off by a plane. It is also a spherical segment of one base, i.e., bounded by a single plane. If the plane passes through the center of the sphere (forming a great circle ), so that the height of the cap is equal to the radius of the sphere, the spherical ...

  3. Laboratory flask - Wikipedia

    en.wikipedia.org/wiki/Laboratory_flask

    Schlenk flask, which is a spherical flask with a ground glass opening and a hose outlet and a vacuum stopcock. The tap makes it easy to connect the flask to a vacuum-nitrogen line through the hose and to facilitate the carrying out of a reaction either in vacuum or in an atmosphere of nitrogen.

  4. Catabolite activator protein - Wikipedia

    en.wikipedia.org/wiki/Catabolite_activator_protein

    Catabolite activator protein (CAP; also known as cAMP receptor protein, CRP) is a trans-acting transcriptional activator that exists as a homodimer in solution. Each subunit of CAP is composed of a ligand -binding domain at the N-terminus (CAP N , residues 1–138) and a DNA-binding domain at the C-terminus (DBD, residues 139–209).

  5. Microparticle - Wikipedia

    en.wikipedia.org/wiki/Microparticle

    Microparticle of spherical shape without membrane or any distinct outer layer. Note : The absence of outer layer forming a distinct phase is important to distinguish microspheres from microcapsules because it leads to first-order diffusion phenomena,

  6. Capsid - Wikipedia

    en.wikipedia.org/wiki/Capsid

    Such a structure is composed of a cylinder with a cap at either end. The cylinder is composed of 10 elongated triangular faces. The Q number (or T mid ), which can be any positive integer, [ 19 ] specifies the number of triangles, composed of asymmetric subunits, that make up the 10 triangles of the cylinder.

  7. Capsule (geometry) - Wikipedia

    en.wikipedia.org/wiki/Capsule_(geometry)

    A two-dimensional orthographic projection at the left with a three-dimensional one at the right depicting a capsule. A capsule (from Latin capsula, "small box or chest"), or stadium of revolution, is a basic three-dimensional geometric shape consisting of a cylinder with hemispherical ends. [1]

  8. Spherical segment - Wikipedia

    en.wikipedia.org/wiki/Spherical_segment

    In geometry, a spherical segment is the solid defined by cutting a sphere or a ball with a pair of parallel planes. It can be thought of as a spherical cap with the top truncated, and so it corresponds to a spherical frustum. The surface of the spherical segment (excluding the bases) is called spherical zone. Geometric parameters for spherical ...

  9. Dewetting - Wikipedia

    en.wikipedia.org/wiki/Dewetting

    The surface of the liquid has the shape of a spherical cap, due to Laplace pressure S = γ SG − γ SL − γ LG {\displaystyle S\ =\gamma _{\text{SG}}-\gamma _{\text{SL}}-\gamma _{\text{LG}}} where γ SG is the solid-gas surface tension , γ SL is the solid-liquid surface tension and γ LG is the liquid-gas surface tension (measured for the ...
