Gravitational collapse and formation of regular black holes: Dymnikova, Hayward, and beyond
European Physical Journal C: Particles and FieldsThe gravitational collapse of a star can lead to the formation of a regular black hole. However, a key factor in this process is the transition of ordinary baryonic matter into a substance that forms the de Sitter core.

Hot Spaghetti: Viscous Gravitational Collapse
, 2017 We explore the fate of matter falling into a macroscopic Schwarzschild black hole for the simplified case of a radially collapsing thin spherical shell for which the back reaction of the geometry can be neglected.

Gravitational collapse of depletion-induced colloidal gels.
Soft Matter, 2016 We study the ageing and ultimate gravitational collapse of colloidal gels in which the interparticle attraction is induced by non-adsorbing polymers via the depletion effect.

Where Does the Physics of Extreme Gravitational Collapse Reside [PDF]
, 2015 The gravitational collapse of massive stars serves to manifest the most severe deviations of general relativity with respect to Newtonian gravity: the formation of horizons and spacetime singularities.

Autonomous Spatiotemporal Regulation of Reversible Hydrogel Actuators by Chemical Reaction Networks
Advanced Materials, EarlyView.Hydrogel actuators with reversible response to thiols are developed using reversible binding of thiols to Michael acceptors. Autonomous spatiotemporal regulation of reversible movement of these hydrogels is achieved using thiol‐based chemical reaction networks containing both positive and negative feedback.

Quantum vacuum effects on the formation of black holes
Journal of High Energy Physics, 2023 We study the backreaction of quantum fields induced through the vacuum polarization and the conformal anomaly on the collapse of a thin shell of dust. It is shown that the final fate of the collapse process depends on the physical properties of the shell,

Nature‐Inspired Design Strategies for Efficient Atmospheric Water Harvesting
Advanced Materials, EarlyView.This review presents advances in bioinspired atmospheric water harvesting systems, emphasizing how structural motifs such as wettability gradients, directional transport, and hierarchical porosity have been translated into engineered fog‐collection and vapor‐sorption strategies for enhanced water uptake, accelerated transport, and energy‐efficient ...

Charged anisotropic spherical collapse with heat flow
European Physical Journal C: Particles and Fields, 2021 In this article, we study the shear-free gravitational collapse of a charged radiating star. The Einstein field equations of gravitational collapse for the charged stars are known to give rise to a high degree of non-linearity in the ordinary ...
