Strengthening the magnetic interactions in pseudobinary first-row transition metal thiocyanates, $\it{M}$(NCS)$_{2}$ [PDF]

open access: yesarXiv, 2020
Understanding the effect of chemical composition on the strength of magnetic interactions is key to the design of magnets with stronger exchange interactions. The magnetic divalent first-row transition metal (TM) thiocyanates are a class of chemically simple layered molecular frameworks.

Oxygen Doping Enables Tailored Built‐In Electric Fields in FeOCl/g‐C3N4 Heterojunctions for Enhanced Peroxymonosulfate Activation

open access: yesAdvanced Functional Materials, EarlyView.
Oxygen‐doping modulated g‐C3N4 support enables a strong built‐in electric field (BIEF) in FeOCl‐OCN.This enhanced BIEF induces the rearrangement of Fe(II)/Fe(III) in FeOCl, which subtly improves intermediates adsorption and also reduces the energy barrier of *O production, thereby achieving efficient PMS activation with 1O2 and Fe(IV)= O as the primary

Otto Billeter or How the Oldest [3,3]-Sigmatropic Rearrangement went to Neuchâtel, Part 2 Otto Billeter oder wie die älteste [3,3]-sigmatrope Umlagerung nach Neuenburg kam: Teil 2

open access: yesCHIMIA, 2000
The historical survey of the uncatalyzed, thermal rearrangement of thiocyanates into isothiocyanates is continued, starting with a review of Otto Billeter's scientific and social career in Neuchâtel. A specific look is taken at 1925 where Ludwig

Constructing chiral MOFs by functionalizing 4,2′:6′,4″-terpyridine with long-chain alkoxy domains: rare examples of neb nets [PDF]

open access: yes, 2016
Reactions of 4′-(4- n alkyloxyphenyl)-4,2′:6′,4″-terpyridines (alkyl = hexyl or nonyl) with CoIJNCS) 2 lead to three structurally characterized chiral 3D assemblies which adopt rare neb topologies.

Integration of Perovskite/Low‐Dimensional Material Heterostructures for Optoelectronics and Artificial Visual Systems

open access: yesAdvanced Functional Materials, EarlyView.
Heterojunctions combining halide perovskites with low‐dimensional materials enhance optoelectronic devices by enabling precise charge control and improving efficiency, stability, and speed. These synergies advance flexible electronics, wearable sensors, and neuromorphic computing, mimicking biological vision for real‐time image analysis and intelligent

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

open access: yesAdvanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.
