Study of merocyanine photoacidity by SERS technique
openLe specie molecolari che subiscono reversibilmente la dissociazione dei protoni acidi in seguito a stimolazione elettromagnetica (i.e. luminosa) vengono chiamate “fotoacidi”.

Oberflaechenverstaerkte Ramanspektroskopie (SERS) an Cyaninfarbstoffen
, 1995 The influence of the molecular structure of cyanine dyes on their SERS behaviour has been studied using colloidal silver and gold as well as silver electrodes as the solid substrate.

Angewandte Chemie, EarlyView.LiMn2O4${\rm LiMn}_2{\rm O}_4$ is of high interest for sustainable energy storage and conversion. Its mixed‐valence Mn3+${\rm Mn}^{3+}$/Mn4+${\text{Mn}}^{4+}$ structure drives site‐specific behavior at aqueous interfaces, featuring proton‐generating Mn4+${\text{Mn}}^{4+}$ centers and electron‐rich Mn3+${\rm Mn}^{3+}$ sites that render the surrounding ...

Angewandte Chemie, EarlyView.This review highlights an emerging anticancer approach integrating platinum agents into photodynamic therapy (PDT) and photoactivated chemotherapy (PACT) systems, further augmented by cancer cell membrane‐ and organelle‐targeting. By directing photoactivated platinum complexes from nontargeted distribution to cancer cells or defined subcellular sites ...

Angewandte Chemie, EarlyView.Click‐to‐release (C2R) chemistry is redirected from payload liberation toward ligand‐directed covalent protein labeling through a transient dihydropyridazine methide (DHP‐methide). This concept opens the way to dual‐functional systems combining covalent target engagement with controlled effector release.

Angewandte Chemie, EarlyView.Mesopore geometry programs the working‐state interface of Fe single sites during nitrate electroreduction. Hexagonal channels reorganize interfacial water and accompany the reversible evolution of isolated Fe─O4‐like sites toward Fe─O─Fe‐like motifs, promoting successive hydrogenation toward NH3 with a Faradaic efficiency of 99.1%.

Gain‐of‐Function Engineering of the NifEN Scaffold Into a Self‐Assembling Nitrogenase
Angewandte Chemie, EarlyView.From scaffold to enzyme: Systematic engineering of the cofactor maturation scaffold NifEN reconstructs the P→M electron relay along with cofactor coordination and proton gating at the S2B site, converting NifEN into a functional nitrogenase capable of ATP‐dependent N2 reduction both in vitro and in vivo.

Generally speaking, Spanish historians (and, of course, the foreign hispanists who, in such matters, trail after them) have not found it useful to read and profit from historians who are defined as "nationalist" (Le., who question the existence of a single and/or simple "Spanish nation" from the narrative perspective of other alleged "national entities"

Angewandte Chemie International Edition, EarlyView.A pyridine‐containing ligation auxiliary eliminates a major bottleneck of peptide ligation chemistry. The extended range of applicable pH values (2.0–7.5) in the ligation reaction helps to avoid epimerization. Native chemical ligation (NCL) proceeds at virtually any junction, including reactions at β‐branched amino acids, as well as O‐glycosylated or O‐
