We present a study of shearfree gravitational collapse using cylindrically symmetric spacetimes whose interior is a non-rotating dissipative fluid bounded by a cylindrical hypersurface beyond which is an Einstein-Rosen vacuum exterior. We consider th

MXenes stand out from other 2D materials because they combine very good electrical conductivity with hydrophilicity, allowing cost-effective processing as thin films. Therefore, there is a high fundamental interest in unraveling the electronic transp

The exact Friedman solution to the field equations of General Relativity (GR) describing an homogeneous and isotropic universe together with its linear and higher-order perturbations are the theoretical roots of the current standard model of cosmolog

In a recent series of papers new exact analytical interior spacetimes sourced by stationary rigidly rotating cylinders of fluids have been displayed. A fluid with an axially directed pressure has been first considered, then a perfect fluid, followed

This study investigated (Ru-)Mo2C (MXene) materials for ammonia thermo-catalytic synthesis under atmospheric or moderate pressure. Under a H2-N2 (3:1) flow, the Mo2C MXene phase showed limited activity in ammonia synthesis at atmospheric pressure at

Mo2Ti2C3Tx MXene materials, bare or loaded with strongly anchored single Pt atoms, were investigated using various methods, including STEM, XPS, XAS and DFT calculations. Upon Pt impregnation, the delaminated Mo-rich MXene surface undergoes partial o

In an important series of articles published during the 70's, Krasi\'nski displayed a class of interior solutions of the Einstein field equations sourced by a stationary isentropic rotating cylinder of perfect fluid. However, these solutions depend o
