TL;DR: In this paper, it was shown that the addition of silica additives to a solution of liquid glass leads to an increase of the number of silicate modules in the liquid glass.

TL;DR: In this paper, the authors investigated the structure of maximal subgroups of GL n (D ) that are radical over the center of D. The results generalize previous results pertaining to the centrally finite case.

TL;DR: In this article, a simple core-shell model with a constant thickness of the surface layer was proposed to study mixed ferrites nanoparticles with structure formula Me1−xZnxFe2O4 (Me = Co, Ni, Cu, Mn) appropriated for self-controlled magnetic hyperthermia (SMHT) for in vivo and in vitro applications.
Abstract: In this paper, we study mixed ferrites nanoparticles with structure formula Me1−xZnxFe2O4 (Me = Co, Ni, Cu, Mn) appropriated for self-controlled magnetic hyperthermia (SMHT) for in vivo and in vitro applications. We discuss in details the influence of the size d, the Zn-ion concentration x on the magnetic characteristics: saturation magnetization MS, coercivity HC, effective anisotropy Keff and specific absorption rate (SAR). From a theoretical point of view we investigate monodispersed, non-interactive, single-domain spherical magnetic nanoparticles (MNPs). We propose a simple core–shell model with a constant thickness of the surface layer. We explain the behaviour of SAR as a function of size and dopping based on two thermal heating mechanisms: the mechanism leading to dynamic hysteresis loops of superparamagnetic origin and the heating mechanism via conventional metastable hysteresis. We investigate also a thermal heating efficiency based on the Zn-ion concentration. We show that whether SAR decreases (increases) when doping increases depends on whether the nanoparticle diameter d is smaller (larger) than the particle size dmax for which SAR has a maximum value. The numerical results are in qualitative agreement with many experimental data.

TL;DR: In this paper, a combined biofilm and activated sludge process was used to enhance biological nitrogen and phosphorus removal in domestic wastewater, where fibrous carriers were packed in an anoxic tank for the attached growth of denitrifying bacteria and the sludge of the clarifier was returned to the anaerobic tank to release phosphate.
