On strongly indefinite systems involving fractional elliptic operators [PDF]
arXiv, 2017 In this paper we discuss the existence and regularity of solutions of strongly indefinite systems involving fractional elliptic operators on a smooth bounded domain $\Omega$ in $\R^n$.

Frequency Dependence of the Dielectric Constants and of the Reflectivity for HfO2 and ZrO2 from First-Principles Calculations [PDF]
, 2006 We present, in this work, our theoretical results for the phonon dispersions and the frequency dependence of the reflectivities and the dielectric constants of ZrO2 and HfO2 in the monoclinic phase. The results show the importance of the lattice contribution for the evaluation of the static dielectric constant.

Recycling of Polyurethane via Mechanocatalytic Methanolysis/Hydrolysis
ChemSusChem, EarlyView.In this study, it is shown that up to 86% of soluble polyol can be recovered from the hydrolysis of polyurethane using a ball milling‐assisted process below 100 °C in the presence of NaOH, a small amount of H2O and a Cu/MgAlOx co‐catalyst. Polyurethane (PU) is the 6th most produced plastic on a global basis, and thus one of the most important targets ...

Ab initio Calculations of the Vibrational Modes of MnAs and Ga1-xMnxAs [PDF]
, 2006 In this work, we present our theoretical results for the equation of state and the phonon dispersions of MnAs, as well as the Mn concentration dependence of both the lattice parameter and the phonon frequencies of the cubic GaMnAs alloys. The results are in good agreement with the experimental results whenever this comparison is possible.

The Depositional Record, EarlyView.Abstract We very much appreciate the comments of André; Pestilho and Agustin Mors on our paper discussing the early diagenesis of the Pre‐salt carbonates (Barra Velha Formation, BVF) in the Santos Basin (Gomes et al., 2024). We welcome the opportunity to respond and to clarify our interpretations concerning dolomite formation, diagenetic timing and ...
