Superimposed Sacrificial Texturing to Enhance the Optical Performance in Thin‐Film Solar Cells

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Sacrificial texturing method using controlled etching of undoped zinc oxide and indium‐doped tin oxide generates microscale and nanoscale textures on glass. Roughness on two different scales is superimposed to create a new texture capable of broad‐spectrum scattering, which is utilised in thin‐film silicon solar cells to enhance optical performance ...

Assessing the Mixing Quality of Hetero‐Aggregates: Applying Mixing Theory to STEM‐EDX Elemental Maps

open access: yesParticle &Particle Systems Characterization, EarlyView.
This study introduces a quantitative method to assess the mixing quality of carbon black‐silica hetero‐aggregates formed in spray flames. Using STEM‐EDX mapping and concepts from mixing theory, the approach characterizes intra‐ and inter‐aggregate homogeneity and particle clustering, enabling precise, composition‐independent evaluation of hetero ...

Quantification of Alkali‐Fluoride Nanoparticle Dissolution in Aqueous Media as a Function of Crystallinity and Surface Modification

open access: yesParticle &Particle Systems Characterization, EarlyView.
Fluoride release kinetics from uncoated and coated β−NaYF4$\ubeta-{\rm NaYF}_4$ and LiYF4${\rm LiYF}_4$ in aqueous solutions are quantified using an ion‐selective electrode coupled to a dialysis compartment. TEM/DLS/ICP‐OES and speciation‐aware modeling complement the fluoride release results.

On the compatibility of single‐scan terrestrial LiDAR with digital photogrammetry and field inventory metrics of vegetation structure in forest and agroforestry landscapes

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The single‐scan approach to terrestrial laser scanning (TLS) and the self‐terrain‐normalized form of drone‐based digital aerial photogrammetry (DAP) offer practical options for rapid assessment of the vegetation structure in tropical landscapes.

Microscale Templating of Functional Particles Using Self‐Limiting Electrospray Deposition

open access: yesSmall, EarlyView.
Self‐limiting electrospray deposition (SLED) uses trapped charge in a growing film to redirect incoming material and produce highly targeted and uniform sprays. Here, nanoparticles are added to sprays to functionalize pre‐patterned electrodes and other devices.
