• Recombination from polar InGaN/GaN quantum well structures at high excitation carrier densities 

  Christian, G. M.; Schulz, Stefan; Kappers, M. J.; Humphreys, C. J.; Oliver, R. A.; Dawson, P. (American Physical Society, 2018-10-02)

  In this paper we report on the emergence of a high energy band at high optically excited carrier densities in the low temperature photoluminescence spectra from polar InGaN/GaN single quantum well structures. This high ...
• A review of wearable solutions for physiological and emotional monitoring for use by people with autism spectrum disorder and their caregivers 

  Taj-Eldin, Mohammed; Ryan, Christian; O'Flynn, Brendan; Galvin, Paul (MDPI, 2018-12-04)

  The goal of real-time feedback on physiological changes, stress monitoring and even emotion detection is becoming a technological reality. People in their daily life experience varying emotional states, some of which are ...
• Revisiting conversion reaction mechanisms in lithium batteries: lithiation-driven topotactic transformation in FeF2 

  Karki, Khim; Wu, Lijun; Ma, Ying; Armstrong, Mark J.; Holmes, Justin D.; Garofalini, Stephen H.; Zhu, Yimei; Stach, Eric A.; Wang, Feng (American Chemical Society, 2018-11-20)

  Intercalation-type electrodes have now been commonly employed in todayâ s batteries due to their capability of storing and releasing lithium reversibly via topotactic transformation, conducive to small structural change, ...
• Activation of CO2 at chromia-nanocluster-modified rutile and anatase TiO2 

  Nolan, Michael; Fronzi, Marco (Elsevier B.V., 2018-11-27)

  Converting CO2 to fuels is required to enable the production of sustainable fuels and to contribute to alleviating CO2 emissions. In considering conversion of CO2, the initial step of adsorption and activation by the ...
• Comparing thermal and chemical removal of nanoparticle stabilizing ligands - effect on catalytic activity and stability 

  Collins, Gillian; Davitt, Fionán; O'Dwyer, Colm; Holmes, Justin D. (American Chemical Society, 2018-11-16)

  The use of stabilizers is an essential part of colloidal catalyst preparation, however their impact on catalytic behavior is challenging to elucidate. This report evaluates three commonly used nanoparticle (NP) stabilizing ...
