The compact-GC platform is a MEMS-based analytical module for the purge&trap pre-concentration and (gas)-chromatographic separation of a sample. The two analytical MEMS (pre-concentrator and GC column) are interconnected by means of a MEMS microfluidic manifold. The microfluidic manifold interconnects the analytical MEMS, but it also acts as injector through the integrated micro-valves.
The innovative manipulation device - micro-gripper - allows the gripping by vacuum of micro-components and integrates a novel system to support their release. The manipulation of millimetric and sub-millimetric components can present several issues, often negligible at the macro-scale.
Molecular doping (MD) is a doping method based on the use of liquid solutions. The dopant precursor is in liquid form and the material to be doped is immersed in the solution. During the immersion process, the molecule containing the dopant atom is deposited on the surface of the material forming a self-assembled monolayer, that is, ordered and compact. Through a subsequent heat treatment, the molecule decomposes and the dopant diffuses.
We propose a portable chemical analysis system capable of identifying chemical substances at trace concentrations (sub-ppm), even in case of a complex matrix of interfering species.
The invention consists of a method and apparatus for the delivery at low pressure (equal to or less than 10-7 Torr) of monoatomic fluorine for reaction with surfaces in an ultra-clean environment. Thanks to the low pressure values involved in the proposed method, the risks associated with the use of fluorine are reduced to a minimum.
This invention comprises an interrogation and readout differential method for chemical sensors based on Surface Plasmon Resonances (SPR). The integration of the SPR sensing unit (chip or other), as intermediate reflecting element of a Fabry-Perot (FP) optical resonator, is the starting point for the application of this method.
The invention consists in a special regulation method of the horizontal axes of operating and rubbing wheels of a centerless grinding machine coupled with an opportune blade profile, allowing a continuous regulation of blade rest angle (angle between tangent to blade profile at the contact point with the work piece and the horizon, denoted by γ) and workpiece height (denoted by hw), without requiring blade substitution and/or manual regulations.
The proposing team that works at CNR ISTEC has recently patented a technology for the production of the Smart Polycrystals (SP), i.e. transparent YAG-based ceramic polycrystals (Y3Al5O12) variably doped with rare earths ions and transition metals ions. The SPs solve the problem of the reduction of the efficiency in the solid state laser systems caused by the inhomogeneous heating of the single crystals during the emission process.
The proposed device is a semi-transparent screen that allows simultaneous viewing of what is beyond the screen and the images projected onto its surface. It consists of two thin glass plates with reflective elements arranged as microlenses, embedded in a resin. The projector's light is reflected by the elements towards the user's eye, while external light passes through the transparent layers without distortion. The transparency and brightness of the screen can be adjusted by modifying the reflective elements.
The working principle of VTTJ is extremely simple. Two parts (at least one with tube shape) are screwed one into the other with a mechanical interference that creates a metallic seal. One part presents a cylindrical slot, the other presents a conical ring, whose diameter is slightly larger than the one of the cylindrical slot. When the two parts are screwed together, a plastic deformation occurs in the mechanical interference region.
