Simple Estimation and Application of the Differential Resistance of a Photovoltaic Module at its Maximum Power Point

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The modulating light irradiation method can estimate the target cell voltage in a working photovoltaic module without electrical contact. This method requires the differential resistances (DRs) of the target cell and module to quantitatively estimate the voltage.

The Stripping Method for X‐Ray Spectral Correction in ISO 4037‐1 Narrow Spectra Series (N10‐N150)

X-Ray Spectrometry, EarlyView.
ABSTRACT Spectrometry is an important tool for the characterization of X‐ray beams in ionizing radiation metrology. However, the use of solid‐state spectrometers for accurate measurements requires correction of spectral distortions caused by the interaction between photons and the detector.

High‐pressure and high‐temperature polymorphism of Na2CO3 up to 10 GPa

Acta Crystallographica Section B, EarlyView.
Two new high‐pressure phases, ϵ and ϵ‐II, observed during in situ experiments, complete the high‐pressure phase diagram of Na2CO3 and show that both the incommensurate γ phase and the ϵ phase are stable over a wider pressure–temperature range under mantle‐relevant conditions.We report two new high‐pressure polymorphs of sodium carbonate, ϵ and ϵ‐II ...
