Abstract: The present invention relates to the synthesis fluorinated quaternary ammonium salts with active fluorinated acrylamide or acrylate group for polymerisation. The fluorinated quaternary ammonium salts can be used as a component for the preparation of immobilized internal electrolyte in maintenance free electrode, lipophilic agents in anion chemical sensor membranes and ionic dopants for conductive hydrogels.

Abstract: The present invention relates to a phosphate sensor (100) for detecting and measuring inorganic phosphate anions. The phosphate sensor (100) is characterised by a substrate (160), a conductor layer (140) disposed on the substrate, and a cobalt nanoparticles composite layer (120) disposed on the conductor layer (140). A method of forming the phosphate sensor (120) is also provided. Figure 1

Abstract: A refraction method and a compound lens is disclosed for concentrating solar beam in a non-imaging manner for its heat to be harvested and utilized, for example, for generating electricity with thermo-electric or thermocouple circuit when its hot junction is heated. Solar beam (S1), which may be collected over a wide span of the sun's movement without need for tracking, is first refracted with a first positive refractory element which may preferably be an asperical biconvex lens (11). The exiting, i.e. second solar beam (S2), at a still convergent angle is then refracted by a second negative refractory element which may preferably be a biconcave lens (12). The exiting, i.e. third solar beam (S3), converges upon a third positive refractory element, preferably another aspherical biconvex lens (13), which concentrates the exiting solar beam (S4) onto the predetermined heat collection surface area (120). The sum of all the curvature surfaces of the compound lens times the indices of refraction is about zero such that the field of focus is flat. Preferably, the sum of refractive powers of the first and third aspherical biconvex lenses is substantially counter-balanced by the refractive power of the second biconcave lens placed thereinbetween said first and third lenses.

Abstract: The present invention provides a method and system for applying ion-selective membrane on Ion-Sensitive Field Effect Transistor (ISFET) surface without involving a mask step. In one embodiment multi-purpose ISFET devices are first prepared at wafer level using a standard Complementary Metal Oxide Semiconductor (CMOS) fabrication process up to Metal I bond pad and ISFET gate window is open for ion sensing purposes. A retaining structure is applied 105 as a protective layer and to define the gate window opening prior to membrane cocktail application 107 by manually pipetting out through a pipette.

Abstract: The present invention relates to the syntheses of fluorinated acrylamides and amino acrylates. The fluorinated acrylamide IV, fluorinated acrylamide V and fluorinated amino acrylate VI can be used as precursor molecules for the preparation of fluorinated quaternary ammonium salts. The fluorinated quaternary ammonium salts can be used as immobilized internal electrolyte in maintenance-free reference electrode, immobilized lipophilic agents in anion chemical sensor membranes and ionic dopants for moisture-retaining conductive hydrogels.
