PRISMS: remote high resolution in situ multispectral imaging of wall paintings

open access: yes, 2008
The non-invasive monitoring and examination of wall paintings in grotto sites, tombs and buildings is particularly important since these paintings are often extremely vulnerable. Traditionally, inspection of wall paintings at high resolution (i.e.

Constructing Cu/Cu2O Heterogeneous Interface for Efficient Urea Electrosynthesis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
In this study, a Cu/Cu2O heterogeneous interface with dual active sites is prepared for electrocatalytic CO2 and NO3− coupling to urea. The catalyst shows high yield rates of 1156.63 mmol g−1 h−1 and FE of 29.67% at −1.0 V (vs RHE), which is significantly higher than Cu and Cu2O, highlighting the advantages of heterogeneous interface synergistic ...

Boosting Photocatalytic H2O2 Synthesis Over HKUST‐1 MOFs‐Derived Hollow HKUST‐1@CuFePBA@CuS Heterojunctions

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
Photoelectron transfer mechanism and photocatalytic O2‐to‐H2O2 reduction process over hollow HS@CuFe@CuS heterojunction photocatalysts. Recently, photocatalytic synthesis of H2O2 has received much attention. However, the photocatalytic activity of photocatalysts is generally limited due to multiple factors, such as insufficiency of photoelectrons, low ...

Synthesis and Characterization of MnO2 nanoparticles mediated by Raphia hookeri seed

open access: yesJournal of Nigerian Society of Physical Sciences
In this study, managanese dioxide nanoparticles (MnO2-NP) was synthesized. Raphia hookeri seed was used as a bioreductant for the synthesis of MnO2-NPs. The biosynthesized MnO2-NPs was investigated for their reaction, structure and morphology.

On the Photo‐Oxidation of Organic Photovoltaic Materials: The Case of PTQ10 and PM6 Blends With Y6‐12

open access: yesSolar RRL, Volume 10, Issue 11, 15 June 2026.
Wantz et al. reveal how donor–acceptor interactions govern light‐induced degradation in organic solar cells. PTQ10 is destabilized, whereas PM6 is partially stabilized by Y6‐12. Crystallinity suppresses photo‐oxidation while modulating performance, defining key design principles for efficient, long‐lived organic photovoltaics.
