Excited‐State Proton Transfer in Push‐Pull N‐Methyl Pyridium Reversible Super‐Photoacids Ruled by Intramolecular Hydrogen‐Bond‐Like Interactions

Chemistry – A European Journal, EarlyView.
Push‐pull A+‐π‐D N‐methyl pyridinium derivatives were found to act as efficient reversible superphotoacids. Upon excitation, they undergo a fast ESPT but recombine with the released proton when the excitation is turned off. In the ortho isomers, intramolecular hydrogen‐bond‐like interactions between the hydroxyl group and the ethenic hydrogen are ...

Heat Capacity and Absolute Standard Entropy of the High Temperature Polymorph of Calcium Boranate and Thermodynamic Calculations Regarding its Decomposition and Rehydrogenation

ChemPhysChem, EarlyView.
The decomposition route and rehydrogenation ability as well as the behavior in the low temperature range of β‐Ca(BH4)2 synthesized by a metathesis reaction are investigated based on heat capacity measurements over a broad temperature range using two different calorimetric techniques.

Cocrystals and Solvates are Not the Same: A Network Perspective

ChemPhysChem, EarlyView.
Based on network analysis, cocrystals and solvates cannot be treated the same. Cocrystals and solvates are two kinds of multicomponent crystals. Cocrystals consist of solid compounds, while solvates consist of a mixture of solid and liquid compounds. This work addresses the question of whether cocrystals and solvates can be treated the same or need to ...

Rethinking Dispersion in Nanotechnology: Biopolymer Nanostructures as Green Enablers of Functional Integration

ChemPlusChem, EarlyView.
Resorting to new nanotechnology may solve nanotechnological challenges. In this perspective, it is highlighted that some nanomaterials coming from Nature are an incipient revolution, not only by their excellent properties per se, but also because these could be tools to turn the processing and applications of “classical” nanomaterials into fully ...

Multianalytical Study of Amuletic and Talismanic Islamic‐African Paper Manuscripts in the Slovene Ethnographic Museum

ChemPlusChem, EarlyView.
The image illustrates a multi‐technique analysis of Islamic‐African manuscripts from the nineteenth to twentieth centuries. It highlights methods like microscopy, hyperspectral imaging, FTIR, LIF, Raman, LIBS, and furnish analysis used to study paper fibers, inks, and dyes—revealing a blend of local and trade materials and a rich fusion of Qur’anic and
