A literature review of analytical techniques for materials characterisation of painted textiles - Part 1: categorising painted textiles, sampling and the use of optical tools [PDF]

open access: yes, 2017
Many types of painted textile are represented in museum collections. Their flexibility, draping qualities, and heterogeneous, layered nature make painted textiles complex objects to conserve. What do we know about their materials and making?

The Newly Discovered Pathway for Oxygen Evolution Reaction: In‐Situ/Operando Characterization Techniques for Catalyst Development

open access: yesCarbon Energy, EarlyView.
This study introduces a newly discovered oxide path mechanism (OPM) for the oxygen evolution reaction (OER), emphasizing the role of in‐situ and operando characterization techniques in unraveling catalyst behavior under realistic conditions. The integration of advanced spectroscopic methods provides new mechanistic insights for the design of highly ...

Multi-Element Analysis by Portable Total Reflection X-ray Fluorescence Spectrometer

open access: yesAnalytical Sciences, 2013
Multi-element solutions containing the 11 elements S, K, Sc, V, Mn, Co, Cu, Ga, As, Br and Y were analyzed by a portable total reflection X-ray fluorescence (TXRF) spectrometer. The excitation parameters (glancing angle, operational voltage and current) and sample amount were optimized for the portable TXRF in order to realize the smallest possible ...

Nanocellulose‐Induced “Surface‐Lock” Engineering: Curbing the Dissolution of MnO2 for High‐Performance Zn–MnO2 Flexible Electrodes

open access: yesCarbon Energy, EarlyView.
The study designed the nanocellulose‐induced “surface‐locking” strategy to stabilize the interface between MnO2 and a carbon‐based substrate. The dissolution of MnO2 was prominently curbed by imparting C–O–Mn bonding and optimized wettability. Zn–MnO2 batteries were endowed with outstanding cyclic stability and improved capacity.

Intrinsically Ultrahigh‐Rate Charging Capability of Conversion Reaction Cathodes and Its Origin: A Mechanism Study on FeS2

open access: yesCarbon Energy, EarlyView.
Origin of the ultrahigh‐rate charge capability of FeS2: FeS2 demonstrates exceptional high‐rate charging capability, delivering 92% capacity retention at 10 C and maintaining as much as 60% capacity retention even at 30 C. This originates from an ultrahigh apparent diffusion coefficient involving both Li+ and Fe2+.
