Investigation of Tin Oxide Atomic Layer Deposition on the Performance of Evaporated Perovskite Solar Cells

open access: yesSmall, EarlyView.
Impact of co‐reactants and their doses utilized during the atomic layer deposition of SnOx on perovskite/C60 structures on the performance of p‐i‐n perovskite solar cells. ABSTRACT Although tin oxide (SnOx) layers grown using atomic layer deposition (ALD) are routinely employed in p‐i‐n perovskite solar cells (PSCs), the correlation between ALD process

Crucial Role of Magnetic Dipole and Anomalous Field Dependence in NiPS3

open access: yesSmall, EarlyView.
Torque magnetometry on the prototypical 2D anisotropic magnet NiPS3, together with relativistic density functional theory calculations, uncovers a distinct intrinsic magnetic anisotropy. The characteristic torque pattern, driven by a high‐field spin‐flop transition, reveals its magnetic response beyond standard XY or XXZ models and highlights the ...

Bimetallic Zn/Cu Metal–Organic Framework (MOF)/ Two‐Dimensional i‐MBene Hybrid Electrodes for Enhanced Supercapacitor Performance

open access: yesSmall, EarlyView.
A Zn/Cu MOF–i‐MBene hybrid electrode (ZC‐MYB) for supercapacitors is developed. The composite retained 81% of its specific capacitance after 9000 cycles, increasing it by 46% over ZC MOF and 5.6‐fold over i‐MBene. At 2 mV/s, the asymmetric ZC‐MYB/AC device produced 73.4 F/g.

Ceramic Raw Materials and Technological Choices in Iron Age Tyre (Lebanon): A Multiproxy, Fabric‐Based Approach

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents a systematically integrated, multiproxy characterisation of Iron Age ceramics from Tyre (Lebanon). Ninety‐nine ceramic samples from stratified Iron Age contexts on Tyre's Acropolis, together with a small Late Bronze Age and raw‐clay reference set, were analysed using petrography, microfossil identification, X‐ray ...

Similar or Different? Configurations of Authenticity Across Museum Types

open access: yesCurator: The Museum Journal, EarlyView.
ABSTRACT Authenticity is traditionally regarded as playing a crucial role in museums, science centers, and memorials. However, despite this fact, authenticity has very different meanings in different (institutional) settings. This complicates shared communications across museum practices.
