A fluidic device (10) is described. The fluidic device (10) comprises the first part (110) and the second part (120). The first part (110) comprises a first inlet (111) and a first outlet (112), mutually spaced apart. The second part (120) comprises a first chamber (121) arranged to contain a predetermined first amount A1 of a first fluid F1 therein and a first wall portion (122) arranged to contain, at least in part, the first fluid F1 in the first chamber (121). The fluidic device (10) is arrangeable in a first configuration, wherein the first part (110) is fluidically isolated from the first chamber (121). The fluidic device (10) is arrangeable in a second configuration, wherein the first inlet (111) and the first outlet (112) are fluidically coupled via the first chamber (121), whereby increasing a first pressure P1 in the first chamber (121) via the first inlet (111) urges at least a part of the predetermined first amount A1 of the first fluid F1 through the first outlet (112).

A fiber laser having an optical cavity that has an optical fiber and a curved mirror for imaging light leaving the fiber back into the fiber. The optical fiber has a round trip dispersion loss of less than 200000 fs2. The round trip length of the optical fiber is less than 2.3 m.
摘要:
The invention provides a method of reducing metal ions (3, 204) present on a substrate (100) comprising contacting the metal ions with a material (2, 201, 202) capable of reducing the metal ions to metal atoms (6, 9) upon exposure to visible light, and exposing the material to visible light (1) whereby to generate metal atoms from the metal ions.
摘要:
The invention provides a method of printing a textile comprising polyester, or a full-chrome, semi-chrome or vegetable-tanned leather, with a vat or a sulfur dye, comprising inkjet printing a solubilised vat dye or a solubilised sulfur dye onto the textile or the leather.
摘要:
An optical parametric oscillator (OPO) comprises a resonant cavity for signal light, and an optically non-linear medium disposed in the resonant cavity for converting pump light into the signal light, wherein the resonant cavity is arranged so that in operation signal light is repeatedly output from and returned to the optically non-linear medium along a signal light path in a continuously repeating cycle, and the OPO comprises delay means for extending the time taken for signal light output from the optically non-linear medium in operation to return to the optically non-linear medium along the signal light path.
摘要:
A method of sealing a leak of fluid from a container comprises introducing a solute to a body of fluid within the container. The solute is selected so as to be soluble in the fluid at the expected conditions prevailing inside the container, and insoluble when the pressure experienced by the fluid is reduced at the site of a leak.
摘要:
This invention provides a method for fabricating geometrical diamond/matrix composites where all or a part of surfaces of the matrix are covered with a diamond film, and to fabricate hollow diamond shells using the composites where a part is uncoated with a diamond film. Hollow diamond shells were prepared by etching out of the matrix soluble with chemicals through an opening, a zone on the matrix, uncoated with diamond film. By changing the shape and the size of the geometrical matrixes, various kinds of diamond/matrix composites and diamond shells in shape and in size can be fabricated. The sizes available are between 200 nm and 2 mm.
