  • Publication number: 20180059412
    Abstract: The invention concerns a method for tuning at a targeted resonance wavelength at least one micro and/or nanophotonic resonator, the resonator having dimensions defining resonance wavelength of said resonator, the resonator being immersed in a fluid containing ions so that the resonator is surrounded by said fluid, wherein the method comprises a step of injecting light, having a light wavelength equal to the resonance wavelength, into the resonator, so that the injected light resonates within the resonator and triggers a photo-electrochemical etching process enabled by the surrounding fluid containing ions, said etching process being enhanced by the optical resonance which amplifies light intensity in the photonic resonator, the etching decreasing dimensions of the photonic resonator, hereby lowering and tuning the resonance wavelength of the photonic resonator.

  • Publication number: 20180036648
    Abstract: A system and method for distillation of a liquid sample at atmospheric pressure for the improved prediction of the heating necessary before the initial boiling point (IBP) of the sample is detected regardless of sample composition to ensure the IBP is observed within certain time constraints. A plurality of infrared (IR) sensors provides real-time temperature control in addition to a conventional measurement of vapor temperature. One IR-sensor monitors the liquid sample temperature in the distillation flask to obtain a corrected IBP time independent of the sample properties. Another IR-sensor monitors the temperature of the rising vapor column as the vapor rises up the neck of the distillation flask. Alternatively, an IR matrix may monitor the temperature of the rising vapor column. The system and method expand the scope of samples analyzed with improved signal, reproducibility, and test accuracy and still remain within the prescribed limits of a selected standard.
