In Situ Generation of Gel Foam via Heat‐Accelerated Calcium Ion Release From Nano‐CaCO3 for Lithium‐Ion Battery Fire Suppression and Prevention

open access: yesAdvanced 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 ...

A Scalable Droplet Microfluidic Platform That Overcomes Large‐Cell Constraints for Long‐Term Plant Cell Culture and Embryogenesis Analysis

open access: yesAdvanced Science, EarlyView.
This work presents a large‐cell‐compatible droplet microfluidic platform that overcomes long‐standing barriers in plant cell culture by enabling high‐fidelity encapsulation, novel multilayer 3D droplet incubation for scalable long‐term culture, and support for the full developmental progression of large plant cells.

Modified gravity and cosmology

open access: yesPhysics 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]

open access: yesEntropy, 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

2021
This 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]

open access: yesPhysical 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 ...
