Simultaneous Determination of Ge, Se and Te in Geological Samples by Inductively Coupled Plasma-Mass Spectrometry

Yankuang ceshi, 2014
The analysis of Ge, Se and Te requires that samples be dissolved by two different acid systems of HNO3-HF-HClO4-H3PO4 and HNO3-HF-HClO4, and determined by Atomic Fluorescence Spectrometry (AFS) and Inductively Coupled Plasma-Mass Spectrometry (ICP-MS ...

CRYSTALLIZATION OF AMORPHOUS Ge IN Ge/Au, Ge/Ag BILAYER FILMS AND Ge-Au, Ge-Ag ALLOY FILMS

Acta Physica Sinica, 1986
In this article, as-evaporated and annealed samples of Ge/Au, Ge/Ag bilayer films and Ge-Au, Ge-Ag alloy films were investigated by TEM. In situ observations of Ge/ polyerystalline Au (p-Au) and Ge/p-Ag films during heating were also made by TEM. It is found that crystallization temperature Tc of amorphous Ge (a-Ge) in a-Ge/p-Au is much lower than Tc ...

Ge(2), Ge(1) and Ge-E′ centers in irradiated Ge-doped silica: a first-principles EPR study

Optical Materials Express, 2015
We present a first-principles investigation of Ge paramagnetic centers in Ge-doped vitreous silica (v-SiO2) based on calculations of the electron paramagnetic resonance (EPR) parameters. We infer, by analyzing g-values differences with respect to our Ge-E′ configurations, that the EPR signal of the Ge(2) center may arise from Ge forward-oriented (Ge-FO)

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.
