Abstract:
Eine Vorrichtung umfasst ein Substrat, das eine Aussparung aufweist und eine Vielzahl von Partikeln, die in der Aussparung angeordnet sind. Ein erster Anteil der Partikel ist mittels einer Beschichtung zu einer porösen Struktur verbunden. Ein zweiter Anteil der Partikel ist nicht mittels der Beschichtung verbunden. Der erste Anteil von Partikeln ist näher an einer Öffnung der Aussparung angeordnet als der zweite Anteil von Partikeln, so dass ein Entweichen des zweiten Anteils von Partikeln aus der Aussparung durch die Öffnung verhindert wird.
Abstract:
The invention relates to a device (10) comprising a substrate (12), which has a recess (14), and a plurality of particles, which are arranged in the recess (14). A first portion of the particles (16) is connected by means of a coating so as to form a porous structure (22), and a second portion of the particles (18) is not connected by means of the coating. The first portion of particles (16) is arranged closer to an opening (19) of the recess (14) than the second portion of particles (18) such that a loosening of the second portion of particles (18) out of the recess (14) through the opening (19) is prevented.
Abstract:
A test method and test apparatus is provided that employs a microfluidic device to characterize properties of a fluid. The microfluidic device has a first inlet port, an outlet port, and a microchannel as part of a fluid path between the first inlet port and the outlet port. While generating a flow of the fluid through the microchannel of the microfluidic device, fluid pressure at the first inlet port of the microfluidic device is measured and recorded in conjunction with varying the controlled temperature of the microchannel of the microfluidic device to characterize the properties of the fluid that flows through the microchannel of the microfluidic device. The properties of the fluid can relate to the clathrate hydrate formation condition of the fluid at the pressure of the flow through the microchannel of the microfluidic device.
Abstract:
Systems and methods for synthesizing chemical products, including active pharmaceutical ingredients, are provided. Certain of the systems and methods described herein are capable of manufacturing multiple chemical products without the need to fluidically connect or disconnect unit operations when switching from one making chemical product to making another chemical product.
Abstract:
A microreactor for photoreactions (101) includes a housing upper part (102), a lid plate (103) made of a material that allows transmission of light, a flow path plate (104) made of a material that suppresses light reflection and has a high thermal conductivity, and a housing lower part (105). Light is applied through a window of the housing upper part (102) and the lid plate (103) to a flow path (109) of the flow path plate (104). The lid plate (103) made of the material that allows transmission of light and the flow path plate (104) made of the material that suppresses light reflection and has a high thermal conductivity are welded each other to form an integrated body.
Abstract:
A microchannel structure including a dispersed-phase introduction channel which communicates with a dispersed-phase introduction inlet; a continuous-phase introduction channel which communicates with a continuous-phase introduction inlet; a discharge channel which communicates with a discharge outlet; a fine-particle formation channel; and a plurality of branch channels for dispersed-phase introduction which are microchannels; wherein one end of the fine-particle formation channel in a fluid traveling direction communicates with the continuous-phase introduction channel whereas the other end thereof communicates with the discharge channel; and wherein a side part of the dispersed-phase introduction channel and side part of the fine-particle formation channel communicate via the plurality of branch channel for dispersed-phase introduction.
