  • Nonstandard Errors

    • In statistics, samples are drawn from a population in a data-generating process (DGP). Standard errors measure the uncertainty in estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation across researchers adds uncertainty-nonstandard errors (NSEs). We study NSEs by letting 164 teams test the same hypotheses on the same data. NSEs turn out to be sizable, but smaller for more reproducible or higher rated research. Adding peer-review stages reduces NSEs. We further find that this type of uncertainty is underestimated by participants.

  • Deposition And Characterization Of Thin Films Based On Nanostructured Wo3 As Sensorial Elements For Detection O F H2S
  • 2020
  • Ingår i: REVISTA ROMANA DE MATERIALE-ROMANIAN JOURNAL OF MATERIALS. - : SERBAN SOLACOLU FOUNDATION. - 1583-3186. ; 50:3, s. 387-394
  • Tidskriftsartikel (refereegranskat)abstract
    • Thin nanostructured films are the state-of-the-art materials for detection of very low limits of toxic gases. The work presents a comparison between the properties of WO3 thin films obtained by two different deposition techniques: Advanced Gas Deposition (AGD) and DC Reactive Sputtering. Films have been characterized by XRD, SEM and XPS. WO3-based sensors have selective sensitivity in H2S detection at operating temperature of 200 degrees C and relative humidity specific to field applications. The potential interferences with CO2, SO2 and NH3 are negligible, highlighting the application potential of WO3.
