Development of hard X-ray photoelectron spectroscopy in liquid cells using optimized microfabricated silicon nitride membranes. [PDF]
J Synchrotron RadiatWe have developed and successfully tested new environmental liquid cells for HAXPES studies using specially designed thin, low‐stress silicon nitride membranes (15 to 25 nm thickness). The novel aspect is the fabrication of the membranes considering the geometry of the experimental setup, the dimensions of the beam and the use of platinum stripes to ...

Chemie Ingenieur Technik, EarlyView., 2023 Let us consider an alternative perspective on climate change: The sum of solar radiation and heat generated by human activity result in a net energy input of 1.96 times that of the Sun on the Earth's surface. The expanding global population is expected to exacerbate this issue. Potential solutions are proposed, including replacement and heat recycling.

Analysis of the escape in systems with four exit channels
Mathematical Methods in the Applied Sciences, Volume 46, Issue 1, Page 1032-1044, 15 January 2023., 2023 In this paper, we have performed a numerical investigation of the escape of a particle from two different dynamical systems with the same number of exit channels. We have chosen specific values of the parameters of the systems so that the openings of the potential well in both systems are approximately of the same size.

The Astrophysical Journal, 2023 The mechanism by which galaxies stop forming stars and get rid of their interstellar medium (ISM) remains elusive. Here, we study a sample of more than 2000 elliptical galaxies in which dust emission has been detected.

Isolated compact elliptical galaxies: Stellar systems that ran away [PDF]
Science, 2015 Galaxies stripped down and evicted It is easy to imagine that the relatively small and dense compact elliptical galaxies once had more to them. Especially when massive galactic neighbors are seen nearby that may have robbed them of their matter, but ...

Why there are no elliptical galaxies more flattened than E7: Thirty years later [PDF]
Serbian Astronomical Journal, 2006 Elliptical galaxies are modeled as homeoidally striated Jacobi ellipsoids (Caimmi and Marmo 2005) where the peculiar velocity distribution is anisotropic, or equivalently as their adjoint configurations i.e.

Phenomenological approach to the modelling of elliptical galaxies: The problem of the mass-to-light ratio [PDF]
Serbian Astronomical Journal, 2007 In this paper the problem of the phenomenological modelling of elliptical galaxies using various available observational data is presented. Recently, Tortora, Cardona and Piedipalumbo (2007) suggested a double power law expression for the global ...

Intrinsic alignments of disc and elliptical galaxies in the MassiveBlack-II and Illustris simulations [PDF]
, 2015 We study the shapes and intrinsic alignments of disks and elliptical galaxies in the MassiveBlack-II (MBII) and Illustris cosmological hydrodynamic simulations, with volumes of $(100h^{-1}Mpc)^{3}$ and $(75h^{-1}Mpc)^{3}$ respectively.
