Sb2Se3 Thin Films for Doping the Absorber in CdTe Solar Cells

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 3, Page 326-335, March 2026.
This study introduces for the first time a new doping route for CdSeTe/CdTe solar cells: A thin Sb2Se3 layer is deposited on the absorber, diffusing Sb into CdTe via subsequent CdCl2 treatment. With this approach, Sb‐doped devices reach efficiencies as high as conventional Cu‐doped cells, while showing much greater stability under accelerated ...

3D imaging of neuronal inclusions and protein aggregates in human neurodegeneration by multiscale x‐ray phase‐contrast tomography

open access: yesBrain Pathology, Volume 36, Issue 2, March 2026.
x‐ray phase‐contrast tomography enabled three‐dimensional, label‐free visualization and quantification of protein aggregates in neurodegenerative diseases with isotropic submicrometer resolution. The study revealed distinct electron density patterns in Lewy bodies, Hirano bodies, granulovacuolar degeneration, and amyloid plaques, highlighting their ...

How Well Do We Know VPDB—Part 2: Interlaboratory Assessment of Existing δ13CVPDB Reference Materials

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 4, 28 February 2026.
ABSTRACT Rationale In January 2024, the IAEA experts meeting endorsed both δ13C scales that are currently used within the scientific community: the Vienna Peedee belemnite (VPDB) δ13C scale defined by NBS 19 with a value of +1.95‰ exactly, and the VPDB‐LSVEC scale defined by NBS 19 and the lithium carbonate LSVEC with a value of −46.60‰ exactly ...

Multi‐Stimulus Triggered Programmable Transformation of Molecular Motor Based Chiral Supramolecular Polymers in Water

open access: yesAngewandte Chemie, Volume 138, Issue 7, 9 February 2026.
We report aldehyde motor–based chiral supramolecular polymers that exhibit light and chemically driven dual responsiveness in water. The supramolecular polymers show transformation and amplification of multi‐state chirality into diverse geometries, offering dynamic control of supramolecular chirality and architectures. Abstract A notable characteristic

Mechanical, Thermal, and Morphological Properties of PA/NBR TPVs: Influence of Processing Conditions and Recyclability

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 8, February 20, 2026.
Dynamic vulcanization at higher shear rates refines PA/NBR morphology, reduces domain size, and maintains mechanical performance after reprocessing. ABSTRACT Thermoplastic vulcanizates (TPVs) of polyamide 6 and nitrile butadiene rubber (PA/NBR) present excellent mechanical properties but traditionally suffer from performance loss during re‐melt ...
