Abstract: A microfluidic device includes a substrate and a microfluidic channel, wherein the microfluidic channel is configured to form a fluid pathway for allowing a fluid sample comprising particles to flow along the microfluidic channel; and a single transducer provided on the substrate for producing an acoustic travelling wave that propagates on the substrate surface towards an interaction region associated with the microfluidic channel as the fluid sample is flowing through the microfluidic channel. The microfluidic channel comprises three channel portions having three orientations, respectively, that are different from each other with respect to a direction of the propagation path of the travelling acoustic wave in the interaction region, the three channel portions arranged to produce fluid wavefronts based on substrate-propagated acoustic waves such that the fluid wavefronts and subsequent substrate-propagated acoustic wavefronts interfere with one another to generate periodic acoustic force fields in the fluid sample for manipulating the particles.

Abstract: In one embodiment, the invention relates to a carbon-based boron removal medium with hydroxyl groups and amine group, and in particular, to a method for forming the carbon-based boron removal medium. In a specific embodiment, nitrogen-doped (“N-doped”) graphene oxide is synthesized by a simple two-step process: (1) oxidation of graphite to graphene oxide, and (2) nitrogen-doping (“N-doping”) the graphene oxide to form the amine group. The resultant N-doped graphene oxide can efficiently remove boron from aqueous solutions. In another embodiment, a method of sensing or detecting the presence of boron in an aqueous solution by using a boron sensing medium comprises at least two hydroxyl groups and at least one pyridinic nitrogen or pyrrolic nitrogen or quaternary nitrogen (i.e. pyridoxine, in particular vitamin B6). The boron ions in the solution would form a highly ionized complex, which can cause significant increase in electrical conductivity of the solution, which can then be used to measure the concentration of boron in said solution.
