Characterization and analytical techniques are methods used to identify, isolate or quantify chemicals or materials, or to characterize their physical properties. They include microscopy, light or radiation scattering, spectroscopy, calorimetry, chromatography, gravimetric and other measurements used in chemistry and materials science.
Due to their plasmonic properties, silver nanoparticles are promising across a vast range of applications, from physics instrumentation to biomedicine and environmental science. Here, the photon-to-heat conversion efficiency of individual nanoparticles is elucidated by designing and fabricating an ultra-sensitive bolometer with 26 pW power resolution.
The authors demonstrate 3D chemical imaging of organic and inorganic materials near or below one-nanometer resolution using multi-modal electron tomography, by fusing elastic and inelastic scattering signals.
Material properties prediction from a given microstructure is important for accelerated design but a comprehensive methodology is lacking. Here, a multi-method machine learning approach is utilized to understand the processing-structure-property relationship for differently processed porous materials.
A powerful technique with broad applications, operando X-ray absorption spectroscopy (XAS) is widely used but there is a lack of design and reporting standards. Focusing on water-splitting electrocatalysts, we propose best practices for the reproducibility, replicability and reliability of operando XAS studies.
To improve the usefulness of the Solar Cells Reporting Summary as a standalone report, we now ask authors of relevant manuscripts to include experimental details in the Summary, and we have updated some of the requested information.
Emily Draper explains how to design and build electrochemical equipment for neutron scattering experiments with simple, at-hand components and techniques.
Adopting standardized and reliable methodologies to accurately measure particle removal efficiency when developing fibrous materials for controlling airborne contamination is crucial. Here, the authors recommend best practices for experimental assessments and reporting to ensure a reliable evaluation of new airborne particle filtration media and technologies.
By tracking the electrochromic doping front, a hole-limited electrochemical doping mechanism is discovered in organic mixed ionic–electronic conductors.
