Predictive Registry Optimization of Molecular Adsorbates on Solid Surfaces

open access: yesAngewandte Chemie, EarlyView.
Local C–H “spikes” from a π‐conjugated backbone lock into graphene “pockets”. A geometric registry score turns images obtained by scanning tunneling microscopy at the solid/liquid interface into atomic‐scale adsorption models, enabling assignment of surface atropisomers in large π‐conjugated molecules.

“Yo te sé peña a peña y rama a rama”: la cultura geo-botanica di Antonio Machado ed il suo interesse per gli esemplari “nimios” della natura

open access: yesAltre Modernità, 2013
The landscape plays a leading role in the poetry of Antonio Machado (1875–1936), whose “simple love of Nature” is innate, inherited within his family environment and cultivated during his formative years at the Instituciόn Libre de Enseñanza.

2D Co‐Mo‐Hydroxide‐Based Multifunctional Material for the Development of H2‐Based Clean Energy Technologies

open access: yesAdvanced Materials, EarlyView.
2D α‐Co(OH)2 interleaved with Mo species displays an appealing dual functionality for the production and use of green hydrogen.Mo incorporation greatly benefits the electrochemical behaviour in Oxygen Evolution Reaction for H2 production, while the magnetocaloric response at liquid H2 temperature paves the way for alternative cryogenic refrigerants ...

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

open access: yesAdvanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

ShuTu: Open-Source Software for Efficient and Accurate Reconstruction of Dendritic Morphology

open access: yesFrontiers in Neuroinformatics, 2019
Neurons perform computations by integrating inputs from thousands of synapses—mostly in the dendritic tree—to drive action potential firing in the axon. One fruitful approach to studying this process is to record from neurons using patch-clamp electrodes,
