Two‐dimensional CoOOH as a Highly Sensitive and Selective

Two‐dimensional CoOOH as a Highly Sensitive and Selective

Jan 25, 2018The authors report that cobalt oxyhydroxide (CoOOH) nanoflakes possess intrinsic oxidizing ability to directly oxidize 3,3′,5,5′-tetramethylbenzidine (TMB) to form a blue colored product (oxTMB) even in the absence of H2O2 and oxygen. In the presence of ascorbic acid (AA), less of the blue product is formed because AA reduces oxTMB. These findings constitute a new scheme for …

  • Using an Infrared Sensor for Reliable Methane Gas Monitoring
    Using an Infrared Sensor for Reliable Methane Gas Monitoring

    A filter in front of the detector blocks out light that is not at the desired wavelength, so the detector measures the attenuation at the specified wavelength only, which is used to determine the concentration of methane present. IR sensors have several advantages over other gas detection technologies: IR sensors have a built-in failsafe system, which comes from the fact that small signals represent high concentrations of gas, while in other sensors …
