Supramolecular assemblies achieve nontrivial structures but there is no general framework to link their formation to molecular properties. Here the authors propose a model that relates molecular geometry and interactions to nanoribbon formation, validated by cryo-electron microscopy.

Welcome to the Nature Communications Editors’ Highlights webpage on inorganic, nanoscale and physical chemistry. Each month our editors select a small number of Articles recently published in Nature Communications that they believe are particularly interesting or important.
The aim is to provide a snapshot of some of the most exciting work published in the area of inorganic, nanoscale and physical chemistry at Nature Communications.

Tracking multiple components of a nuclear wavepacket in photoexcited Cu(I)-phenanthroline complex using ultrafast X-ray spectroscopy
Nonadiabatic excited state processes involve mixing of electronic and nuclear wavefunctions, which are difficult to disentangle. Here the authors explore by time-resolved X-ray absorption near edge structure the wavepacket dynamics of a copper(I)-phenanthroline complex, resolving different vibrational modes.
Ferroelectric fatigue degrades ferroelectric properties upon polarization cycling, but its underlying chemistry is poorly understood. Here, the authors show by multimodal chemical imaging that fatigue in PbZr0.2Ti0.8O3 thin films is associated with Cu + ions migration from the electrode into the film structure.
Polyethers are ubiquitous in our daily lives, and display counterintuitive solubilities in water. Here the authors show, by ultrafast spectroscopies and computations, that solubility does not depend on steric factors but on the interaction of water molecules with the polymer’s charge distribution
Radiosensitisers are believed to interfere with cancer cells by dissociating upon interaction with electrons. Here the authors observe instead that the dominant path for nitroimidazolic radiosensitisers involves formation of a non-dissociated radical anion, prerequisite for their accumulation in tumour cells.
The band gap of metal halide perovskites can be tuned by changing composition, but the underlying mechanism is not well understood. Here the authors determine, by experiments and theoretical analysis, the energy levels of all primary tin- and lead-based perovskites, relating them to the levels of the composing ions.
Solutions of proteins and other molecules can host puzzling, solute-rich inclusions of mesoscopic dimensions. Here the authors report a mechanism by which mesoscopic clusters can nucleate and ripen, requiring that the solute form long-lived complexes, with implications for biologically and industrially relevant systems.
Efficient electron transfer across hydrogen bond interfaces by proton-coupled and -uncoupled pathways
Thermal electron transfer across hydrogen bond remains largely unexplored. Here the authors demonstrate that electron self-exchange through hydrogen bonds is highly efficient and can proceed either via the known proton-coupled pathway or an overlooked proton-uncoupled pathway
High-flux ultrafast extreme-ultraviolet photoemission spectroscopy at 18.4 MHz pulse repetition rate
Space charge effects can distort the results of photoelectron spectroscopic measurements, and usually limit the allowable photon flux in an experiment. Here, the authors present an 18.4 MHz repetition rate high harmonic source in the 25–60 eV range, with a large count rate improvement over state-of-the-art attosecond setups under identical space charge conditions.
Observation of dissociative quasi-free electron attachment to nucleoside via excited anion radical in solution
Radiation-induced low-energy electrons in solution are implicated in DNA damage, but their relaxation dynamics are not well understood. Here the authors observe how quasi-free electrons dissociate glycosidic bonds via an excited nucleoside anion radical, whereas solvated electrons reside on the nucleoside as a relatively stable anion radical.
