Microfluidic chips are widely used in the field of biopharmaceuticals, chemical synthesis, separation, and purification. Different requirements are asserted by different applications on the bonding processes of the microfluidic chips. In this paper, the easy-disassembly leak-tight encapsulation of the PDMS microfluidic chip was studied. A bonding method based on selective oxygen plasma treatment of...
A novel secondary optical design for LED lamps with high color rendering indices (CRI) and adjustable correlated color temperature (CCT) is proposed. RGB LED cells are assembled in a three dimensional manner together with a set of beam mixers. Perfect light mixing is resulted by optimizing the structural parameters of the reflectors and beam mixers. A supplement amber LED is used for light compensation...
