A Novel Polyvinyl Alcohol‐Based Hydrogel with Ultra‐Fast Self‐Healing Ability and Excellent Stretchability Based on Multi Dynamic Covalent Bond Cross‐Linking

open access: yesMacromolecular Materials and Engineering, 2023
A novel self‐healing poly(vinyl alcohol) (PVA)‐based hydrogel is developed by cross‐linking PVA chains through multi dynamic covalent bonds by use of a small cross‐linker composed by 4‐formylphenylboric acid (FPBA) and lysine (Lys).

Unraveling beam self-healing

open access: yes, 2017
We show that, contrary to popular belief, non only diffraction-free beams may reconstruct themselves after hitting an opaque obstacle but also, for example, Gaussian beams.

Self healing of vacancy defects in single layer graphene and silicene [PDF]

open access: yes, 2013
Self healing mechanisms of vacancy defects in graphene and silicene are studied using first principles calculations. We investigated host adatom adsorption, diffusion, vacancy formation and revealed atomistic mechanisms in the healing of single, double ...

Enhanced self-healing capacity in cementitious materials by use of encapsulated carbonate precipitating bacteria : from proof-of-concept to reality [PDF]

open access: yes, 2013
In this study, two bacteria-based self-healing systems were developed for the proof-of-concept and approach to a realistic self-healing. A self-healing system with glass capillaries and silica sol gel carried bacterial cells was first built.
