Systems and methods taught herein enable simultaneous forward and side detection of light originating within a microfluidic channel disposed in a substrate. At least a portion of the microfluidic channel is located in the substrate relative to a first side surface of the substrate to enable simultaneous detection paths with respect to extinction (i.e., 0°) and side detection (i.e., 90°). The location of the microfluidic channel as taught herein enables a maximal half-angle for a ray of light passing from a center of the portion of the microfluidic channel through the first side surface to be in a range from 25 to 90 degrees in some embodiments. By placing at least the portion of the microfluidic channel proximate to the side surface of the substrate, a significantly greater proportion of light emitted or scattered from a particle within the microfluidic channel can be collected and imaged on a detector as compared to conventional particle processing chips.

The invention relates to a microfluidic system based on active control of flow resistance and balancing pressures in microfluidic channels and an improved method for disposable microfluidic devices and cartridges for use in, but not limited to, in-vitro diagnostics. The microfluidic system and device of the invention does not utilize mechanical moving parts to control the fluid flow and has no external fluidic connection to the instrument or fluidics controller.

Disclosed is a method for preparing β-phenylethanol. The method comprises the following steps: (1) reducing a catalyst in a reactor in advance; (2) introducing pre-heated hydrogen gas to warm the reactor to a predetermined temperature; and (3) introducing a raw material styrene oxide to perform a hydrogenation reaction so as to obtain the β-phenylethanol. The catalyst is Ni—Cu/Al.sub.2O.sub.3 nanosized self-assembled catalyst. The reactor is an ultrasonic field micro-packed bed reactor. The method of the present invention enables the selectivity of the β-phenylethanol to reach 99% or more.

The present invention relates to a device for the photocatalytic reduction of a substance with a structured reaction plate and/or a structured housing, wherein the reaction plate has, at least in some regions, a surface which contains a material with negative electron affinity and which can be electronically excited with radiation having a wavelength of ≥180 nm.

The present invention relates to a microfluidic flow process for making monomers, monomers made by such processes, and methods of using such monomers. In such process, microfluidic reaction technology is used to synthesize cyanation reaction products orders of magnitude faster than is possible in batch and continuous syntheses. The aforementioned process does require strictly regulated, highly toxic cyanogen chloride. Thus the aforementioned process is more economically efficient and reduces the environmental impact of thermosetting resin monomer production, and produces thermosetting resin monomers in greater purity than obtained through typical processes.
