Reactores nucleares.

open access: yes, 1961
Sabemos que existen unas partículas sin carga eléctrica, llamadas neutrones, que pueden penetrar en el núcleo de los átomos venciendo la barrera de potencial eléctrico que existe alrededor de dichos núcleos. Dichas partículas son capaces, en determinados casos, de romper, de dividir, el niicleo atómico con que chocan, en dos ...

An ATP‐Mediated Antibiotic β‐Peptide Nanofiber That Kills Multidrug‐Resistant Bacteria via a Multistage Mechanism

open access: yesAdvanced Science, EarlyView.
The 3K‐AP system forms infinite supramolecular fibrils that undergo controlled degradation into shorter fragments upon enzymatic hydrolysis. Multitechnique imaging reveals a stepwise bacteriolytic mechanism involving bacterial entrapment, disassembly into lethal constructs, and associated extracellular vesicle release, highlighting the dynamic ...
