Systematic and Collaborative Approach to Problem Solving using X-ray Photoelectron Spectroscopy

Collaborators from the UK, France, Germany, Canada, Denmark and the USA – including our technical manager, Dr David Morgan – have published a recent article in Applied Surface Science Advances [1], highlighting the methodology developed from many years of interaction between junior and senior X-ray Photoelectron Spectroscopy (XPS) practitioners using […]

Photoemission of Solvated Electrons

Buttersack et al. have recently published what seems to be the first photoemission experiments on solvated electrons.1 Solvated electrons occur when group 1 metals are dissolved in certain solvents, the most popular is liquid ammonia. Once a standard undergraduate chemistry experiment, dropping a lump of sodium into liquid NH3, cooled […]

In Situ Irradiated X-ray Photoelectron Spectroscopy on the Ag-Zn0.5Cd0.5S Core–Shell Structure and the Hydrogen Production Activity

Shen-wei Bai, Hui Mei,*Gang-qiang Zhu, Ming-gang Zhang, Wei-zhao Huang and Lai-fei Cheng DOI: https://doi.org/10.1021/acssuschemeng.0c01085 In this paper, the authors develop a Ag core – Zn0.5Cd0.5S semiconductor shell nanoparticle for the photocatalytic production of hydrogen from water (Figure 1). The aim was to develop a nanocomposite which may utilise the intrinsic […]
