Tailored Frequency Conversion in Nonlinear Subwavelength Grating Metaslabs
Laser &Photonics Reviews, EarlyView.Subwavelength gratings are introduced as a tool for flexible, accurate control of phase matching (PM) in integrated optical frequency converters. Implemented in partially etched GaAs metaslab waveguides, tuning of the second‐harmonic PM wavelength by up to 100 nm is achieved, with wider ranges predicted by simulations.

Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Magnetic Resonance in Medicine, EarlyView.Abstract Purpose To combine large field‐of‐view abdominal 1H$$ {}^1\mathrm{H} $$ and quantitative sodium ( 23Na$$ {}^{23}\mathrm{Na} $$) MRI in the same position at 7 T to enable the quantification of the tissue sodium concentration via 23Na$$ {}^{23}\mathrm{Na} $$ MRI and the anatomical assignment in 1H$$ {}^1\mathrm{H} $$ images without repositioning

Magnetic Resonance in Medicine, EarlyView.Purpose Hyperpolarized (HP) carbon‐13 (13C) MRSI provides real‐time information about metabolic processes but lacks high temporal and spatial resolution. This study introduces a multi‐echo–balanced steady‐state free precession (ME‐bSSFP) method with a 3D radial readout trajectory in a spiral phyllotaxis pattern as a method for non‐Cartesian HP 13C MRSI

ChemistryOpen, EarlyView.A capillary plasma jet is used to generate H2O2 in situ to fuel enzymatic hydroxylation reactions. H2O2 production is tuned by adjusting the water vapor in the feed gas to accommodate unspecific peroxygenase from Agrocybe aegerita. Together, enzyme immobilization and an active prevention of product inhibition and H2O2 buildup increase enzyme ...
