Qualitative Analysis of Biogas by Raman Spectroscopy: Effect of Pressure on Major Components

Journal of Raman Spectroscopy, EarlyView.
Raman spectra of major and selected minor biogas components were studied under pressures up to 100 bar. Pressure‐induced shifts and band broadening were quantified for methane, carbon dioxide, and nitrogen, while Raman spectra of ammonia and hydrogen sulfide are presented in the context of biogas quality monitoring.

Sensor Arrays With Integrated Track and Hold Circuits Manufactured on Glass

Journal of the Society for Information Display, EarlyView.
The integration of track and hold circuits into current or light sensor arrays based on thin‐film devices on glass allows the recording of all sensing elements at the same time. This enables the recording of dynamic situations, overcoming the disadvantage of low bandwidths or low photosensor response times.

Functional Effects of the Pioneer Fern Dicranopteris on Soil Fertility and Its Spatial Patterns in Degraded Hilly Landscapes

Land Degradation &Development, EarlyView.
ABSTRACT Vegetation recovery is vital for reversing soil degradation in subtropical red soil regions. This study evaluates the role of the pioneer fern Dicranopteris in enhancing soil fertility and its spatial variability across degraded hills in South China.

Toward Highest Frequency, Phase‐Sensitive Electric Field Sensing Enabled by Plasmonic Circuits

Laser &Photonics Reviews, EarlyView.
An electromagnetic field sensor using an optical sensor head for distortion‐free, high‐sensitivity measurements with potential for high‐frequency operation is presented. The frequency response is enabled by an antenna‐integrated plasmonic modulator. The sensitivity is calculated, and optimizations to obtain thermal‐background‐limited sensitivity are ...
