In Situ Liquid‐Cell Transmission Electron Microscopy Insights Into Lithium‐Ion Battery Materials Degradation: Challenges and Emerging Solutions

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
Lithium‐ion battery degradation arises from complex, localized processes during operation, limiting long‐term performance. In situ electrochemical liquid cell TEM provides unique access to these mechanisms. This review summarizes degradation phenomena revealed by liquid cell TEM, traces the evolution of the three main cell designs, compares their ...

Experimental and Computational Raman and SERS Study of Acid Blue 113

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 2, Page 239-254, February 2026.
The vibrational features of AB‐113 were investigated through experimental and theoretical analyses. SERS spectra showed enhanced responses under resonant excitation, especially at 532 and 632.8 nm, enabling identification limits as low as 1.0 × 10−8 mol L−1.

Two-Higgs-Doublet Models with CP violation [PDF]

open access: yes, 2002
We consider the Two-Higgs-Doublet Model and determine the range of parameters for which CP violation and Flavor Changing Neutral Current effects are naturally small.

Labour Dynamics, Factor Substitution and Capital Adoption in Sub‐Saharan African Agriculture

open access: yesJournal of Agricultural Economics, Volume 77, Issue 1, Page 183-204, February 2026.
ABSTRACT Ongoing structural transformations in many Sub‐Saharan African (SSA) economies are driving changes in labour inputs and wages, likely influencing smallholder agriculture and the direction of agricultural intensification processes. At the same time, the adoption of capital‐intensive technologies still remains puzzlingly low.

Measuring individual overpotentials in an operating solid-oxide electrochemical cell

open access: yes, 2010
We use photo-electrons as a non-contact probe to measure local electrical potentials in a solid-oxide electrochemical cell. We characterize the cell in operando at near-ambient pressure using spatially-resolved X-ray photoemission spectroscopy.

Toward eco‐sustainable afforestation in arid lands: key lessons from a 23‐year‐old arboretum of native and non‐native trees in Jordan

open access: yesRestoration Ecology, Volume 34, Issue 2, February 2026.
Abstract Introduction Afforestation is a key restoration strategy for mitigating land degradation and desertification in semiarid regions. However, evaluating the ecological impacts of tree species used for sustainable dryland restoration is crucial. For example, non‐native tree species may become invasive, with negative effects on native understory ...

Monetary Union in West Africa and Asymmetric Shocks: A Dynamic Structural Factor Model [PDF]

open access: yes
The Ghana cocoa market has been extensively liberalised over the period since the mid 1980s. Three issues have been prominent in microeconomic research on the effects of liberalisation on agriculture.
