Advancements in Understanding the Physicochemical Properties of Reticular Materials: An In Situ and Operando Spectroscopic Perspective

open access: yesAdvanced Materials, EarlyView.
This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

Recent Advances in Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

Photocatalytic Alkylation of C(sp3)−H Bonds Using Sulfonylhydrazones**

open access: yesAngewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
Herein, we report the realization of an alkyl‐alkyl cross‐coupling reaction, which combines N‐sulfonyl hydrazones and C(sp3)−H donors through a diarylketone‐enabled photocatalytic hydrogen atom transfer and a subsequent fragmentation of the obtained alkylated hydrazide.

Toward Direct Laser Writing of Dual‐Layer Metasurfaces with the Plasmonic Phase‐Change Material In3SbTe2

open access: yesAdvanced Optical Materials, EarlyView.
A simple optical programming technique is developed for fabricating plasmonic nanoantennas in a dual‐layer metasurface by crystallizing the plasmonic phase‐change material In3SbTe2 from the top and through the substrate with a subsequent reamorphization step.

The Plimpton 322 Tablet and the Babylonian Method of Generating Pythagorean Triples [PDF]

open access: yesarXiv, 2010
Ever since it was published by Neugebauer and Sachs in 1945, the Old Babylonian tablet known as Plimpton 322 has been the subject of numerous studies leading to different and often conflicting interpretations of it. Overall, the tablet is more or less viewed as a list of fifteen Pythagorean triplets, but scholars are divided on how and why the list was
