Study on the Optimal Reaction Temperature and Sampling Weight for Measurement of Carbon and Nitrogen Isotope Ratio by Elemental Analyzer-Isotope Ratio Mass Spectrometer

Yankuang ceshi, 2018
Carbon and nitrogen isotopes are essential tools to study paleoclimate, palaeoenvironment, and ecosystem. At present, carbon and nitrogen isotopes are commonly determined by Elemental Analyzer-Isotope Ratio Mass Spectrometer (EA-IRMS).

Engineered Protein‐Based Ionic Conductors for Sustainable Energy Storage Applications

Advanced Materials, EarlyView.
Rational incorporation of charged residues into an engineered, self‐assembling protein scaffold yields solid‐state protein films with outstanding ionic conductivity. Salt‐doping further enhances conductivity, an effect amplified in the engineered variants. These properties enable the material integration into an efficient supercapacitor.
