Enhancing Direct Solar Water Splitting via ALD of Multifunctional TiO2/Pt Nanoparticle Coatings With Engineered Interfaces to GaAs/GaInP Tandem Cells

open access: yesAdvanced Functional Materials, EarlyView.
Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.

Push-and-Twist Drillstring Assemblies [PDF]

open access: yes, 2017
Deep drilling using a rigid drillstring requires the assembly and disassembly of multiple drill pipes. The interfaces between these pipes provide a challenge for automation because they must transmit large drilling forces and movements while, at the same

The Social Production of Age, Space and Exclusion: Towards a More Theory‑Driven Understanding of Spatial Exclusion Mechanisms in Later Life

open access: yesSociální studia, 2018
Gerontology has for a long time been described as “data rich, but theory poor”. This is true for the study of spatial exclusion, too: in a recent scoping review on old‑age exclusion, Walsh and his colleagues called for more theoretical work in the field ...
