Development of the web-based NIST X-ray Photoelectron Spectroscopy (XPS) Database

Data Science Journal, 2006
The first Web-based version of the NIST X-ray Photoelectron Spectroscopy Database (XPSDB) is described. The current database, built from a relational database management system (RDBMS), contains critically evaluated data with over 19,000 line positions ...

A Review of Transient Characterization Techniques for Quantum Dot Light‐Emitting Diodes

Advanced Physics Research, EarlyView.
This review surveys transient characterization techniques for quantum dot light‐emitting diodes, including TRPL, TREL, TA, and E‐TA. These methods resolve carrier‐selective dynamics across multiple time scales, enabling direct analysis of charge injection, exciton formation and recombination, efficiency roll‐off, and device degradation.

Tracking primary thermalization events in graphene with photoemission at extreme timescales

, 2015
Direct and inverse Auger scattering are amongst the primary processes that mediate the thermalization of hot carriers in semiconductors. These two processes involve the annihilation or generation of an electron-hole pair by exchanging energy with a third

Defect engineering for highly efficient and stable perovskite top cells for Si tandems

Bulletin of the Korean Chemical Society, EarlyView.
Defect passivation in wide‐bandgap perovskites is essential for enabling high‐efficiency and stable perovskite/Si tandem solar cells. Bulk, surface, and buried‐interface passivation strategies focus on suppressing nonradiative recombination, ion migration, and halide segregation, thereby clarifying critical design principles for next‐generation tandem ...

Oxophilicity‐Driven Potential Window Engineering Enables Scalable and Low‐Emission Paired Electrosynthesis on Asymmetric CuOx@Ag Platform

Carbon and Hydrogen, EarlyView.
An asymmetric CuOx@Ag electrocatalyst platform enables paired electrochemical valorization of glycerol and 4‐nitrophenol, while effectively decoupling both half‐reactions from OER and HER. Ag‐mediated surface engineering expands the potential window and boosts reaction selectivity, achieving > 90% Faradaic efficiencies at both electrodes.

Tribological Behaviour of Bonded Solid Lubricant Film in Air and in Vacuum

Communications, 2000
The friction tests of inorganic bonded composite solid lubricant films (WS2, graphite, BN) were performed in laboratory air and in 10-4 Pa vacuum. The wear traces and transfer films were characterized by scanning electron microscopy (SEM), and Auger ...

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...
