Advanced Science, EarlyView.We present a heat‐accelerated in situ crosslinking strategy to create an alginate gel foam for lithium‐ion battery fire suppression. At ambient temperature, the formulation maintains low viscosity for easy foam generation. After exposure to fire, δ‐gluconolactone hydrolysis accelerates, enabling rapid Ca2+ release from CaCO3 and rapid ionic ...

Modified gravity and cosmology
Physics Reports, 2012 In this review we present a thoroughly comprehensive survey of recent work on modified theories of gravity and their cosmological consequences. Amongst other things, we cover General Relativity, Scalar-Tensor, Einstein-Aether, and Bimetric theories, as well as TeVeS, f(R), general higher-order theories, Horava-Lifschitz gravity, Galileons, Ghost ...

Viscosity in Modified Gravity [PDF]
Entropy, 2012 A bulk viscosity is introduced in the formalism of modified gravity. It is shownthat, based on a natural scaling law for the viscosity, a simple solution can be found forquantities such as the Hubble parameter and the energy density. These solutions mayincorporate a viscosity-induced Big Rip singularity.

Galaxy Clusters and Modified Gravity
2021This section reviews the potential of galaxy clusters to probe the nature of the gravitational law and dark energy at large scales. Focusing on the predictions of the most popular theories beyond General Relativity, we discuss the key phenomenological implications, their confrontation with observations, along with the relevant current constraints ...

Modified teleparallel theories of gravity [PDF]
Physical Review D, 2015 We investigate modified theories of gravity in the context of teleparallel geometries. It is well known that modified gravity models based on the torsion scalar are not invariant under local Lorentz transformations while modifications based on the Ricci ...
