Activation of Stainless Steel 316L Anode for Anion Exchange Membrane Water Electrolysis

2023

The increased emphasis on renewable energy has resulted in a surge of R&D efforts into hydrogen and battery research. The intensive electrochemical environment surrounding the anodic oxygen evolution reaction (OER) has plagued both the activity and stability of the catalytic layer, substrate and porous transport layer, ultimately affecting both these industries. Herein, we report the benefits of potential cycling (PC) a 316L stainless steel felt porous transport layer (PTL) for use in anion exchange membrane water electrolysis. The PC increased surface roughness and created a CrFe5Ni2-OxHy layer through the oxidation of iron as shown by SEM, EDS, XPS, XRD and Raman spectroscopy. Post-PC tes…

Studies of transition-edge sensor physics : thermal models and noise

2011

This thesis focuses on studying the noise in transition-edge sensors (TES). More specifically, the aim is to find an explanation for the observed excess noise that is limiting their performance and has been troubling the TES field in recent years. Several theories have been put forth but a definitive answer is still missing. In the early stages of this thesis work a novel theory was presented for the noise in a special TES geometry. In our theory the excess noise is caused by correlated fluctuations of superconductivity at the phase boundary between normal and superconducting states. Data from more recent experiments does not give solid support for the theory and in this thesis the validity…

Modelling the Electromechanical Impedance Method for the Prediction of the Biomechanical Behavior of Dental Implant Stability

2015

Abstract We propose the electromechanical impedance (EMI) technique to assess the stability of dental implants. The technique consists of bonding a piezoelectric transducer to the element to be monitored. Conventionally, electromechanical admittance is used to diagnose structural damage. In this study, we created a 3D finite element model to mimic a transducer bonded to the abutment of a dental implant placed in a host bone site. We simulated the healing after surgery by changing the Young's modulus of the bone-implant interface. The results show that as the Young's modulus of the interface increases, the electromechanical characteristic of the transducer changes.

CS 29497-004 abundances

2017

We report an abundance analysis for the highly r-process-enhanced (r-II) star CS 29497-004, a very metal-poor giant with solar system Teff=5013K and [Fe/H]=-2.85, whose nature was initially discovered in the course of the HERES project. Our analysis is based on high signal-to-noise ratio, high-resolution (R~75000) VLT/UVES spectra and MARCS model atmospheres under the assumption of local thermodynamic equilibrium, and obtains abundance measurements for a total of 46 elements, 31 of which are neutron-capture elements. As is the case for the other ~25 r-II stars currently known, the heavy-element abundance pattern of CS 29497-004 well-matches a scaled solar system second peak r-process-elemen…

Gaia-ESO Survey. Trumpler 23

2017

Trumpler 23 is a moderately populated, intermediate-age open cluster within the solar circle at a R_GC_~6kpc. It is in a crowded field very close to the Galactic plane and the color-magnitude diagram shows significant field contamination and possible differential reddening; it is a relatively understudied cluster for these reasons, but its location makes it a key object for determining Galactic abundance distributions. New data from the Gaia-ESO Survey enable the first ever radial velocity and spectroscopic metallicity measurements for this cluster. We aim to use velocities to isolate cluster members, providing more leverage for determining cluster parameters. Gaia-ESO Survey data for 167 p…

Managing collapsed boundaries in global work

2023

Global workers have long contended with the challenges of working across geographical, temporal, and cultural boundaries enabled by communication technologies. However, the global work research has rarely intersected with the literature on work–home boundary management—which has been brought to the forefront due to the forced move to remote work during the Covid-19 pandemic. Drawing on a qualitative field study of 55 in-depth interviews with global workers from a large organization headquartered in the Nordics, we found that global workers drew on sociomaterial affordances to manage both global work and work–home boundaries through strategies of boundary support and boundary collapse. Altho…

Monialaisen ohjauksen rakentuminen ohjaustilanteissa: onko monialainen ohjaus monialaista?

2022

Monialaisia ohjauspalveluita perustellaan niiden myönteisillä vaikutuksilla asiakkaisiin, työntekijöihin ja mukana oleviin palveluntuottajiin, mutta monialaista ohjausta koskeva empiirinen ja teoreettinen tutkimusnäyttö on toistaiseksi vähäistä. Tarkastelemme artikkelissamme sitä, miten eri tavoin monialaista ohjausta toteutetaan toiminnan tasolla. Aineiston muodostaa vuosina 2018–2019 kerätty havainnointiaineisto nuorten ohjaus- ja neuvontapalveluja tuottavan Ohjaamon ohjaustilanteista (n = 68). Kysymme, millaisiin erilaisiin tekoihin monialainen ohjaus jäsentyy ohjauksen työmuodon ja ammatillisten toimintatapojen perusteella, joita olivat ohjaajien lukumäärä, ohjauksen tavoite, ohjauksen …

The relationship between working alliance with peer mentors and eating psychopathology in a digital 6‐week guided self‐help intervention for anorexia…

2021

Objective: The quality of working alliance (WA) is associated with treatment outcomes across several types of psychiatric disorders and psychological interventions. This study examined the role of WA with peer mentors (people with lived experience of illness) and student mentors (graduated psychology students) in a 6-week, digital, guided self-help (GSH) intervention for anorexia nervosa. Method: Ninety-nine patients rated weekly, for 6 weeks: (a) eating psychopathology using the short version of the Eating Disorder Examination Questionnaire (EDE-QS) and (b) WA with a student mentor (n = 14) or a peer mentor (n = 10). WA was assessed by asking patients the extent to which they felt comforta…
