Laser‐Based In Situ Diagnostics of Temperature and Material‐Growth Dynamics in Photothermal Laser Nanoprinting of ZnO

open access: yesLaser &Photonics Reviews, EarlyView.
This work elucidates the previously unknown thermal dynamics during sub‐micrometer photothermal laser printing of zinc oxide using a non‐invasive transmission‐based in situ measurement. The elevated temperatures are shown to be highly localized around the laser focal spot, reaching average temperature increases of about 113 K per mW of laser power ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

open access: yesVIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing

open access: yesActa Ophthalmologica, EarlyView.
Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.
