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 …

    Nov 21, 2015A typical 660-MW stator should drop around 10 mbar within 12 h. If the vacuum test results are unsatisfactory, a mixture of air and 20 per- cent (by volume) of a tracer gas should be pressurized in the winding. A leak search should then be performed, using an electronic gas detector.
