Comparison of alternative neutral detergent fiber methods to the AOAC definitive method by Mary Beth Hall, David R. Mertens

“…The current definitive method for NDF treated with amylase (aNDF) is AOAC Official Method 2002.04 performed on dried samples ground through the 1-mm screen of a cutting mill with refluxing and then filtration through Gooch crucibles without (AOAC−; reference method) or with (AOAC+) a glass fiber filter filtration aid. …”

The Impact of BiF₃ Doping on the Yb³⁺ to Yb²⁺ Reduction during the LiYF₄:Yb³⁺ Crystal-Growth Process by Amir Khadiev, Niyaz Akhmetov, Stella Korableva, Oleg Morozov, Alexey Nizamutdinov, Vadim Semashko, Maksim Pudovkin, Marat Gafurov

“…Here, we report on the opportunity to suppress Yb³⁺ to Yb²⁺ dopant-ion reduction in LiYb_xY_1−xF₄ mixed crystals during growth processes, using the Bridgmen–Stocbarger technique in graphite crucibles in vacuum. This was carried out by the additional doping of the LiF-YF₃-YbF₃ powder mixture with 1% of BiF₃ additive. …”

Luminescence Properties of Y₃F[Si₃O₁₀]:<em>Ln</em>³⁺ (<em>Ln</em> = Eu, Tb, Er) with <em>Thalenite</em>-Type Host Lattice and Crystal St... by Marion C. Schäfer, Michael Petter, Ingo Hartenbach, Ralf J. C. Locke, Shuang Zhang, Claudia Wickleder, Thomas Schleid

“…With Tm₃F[Si₃O₁₀], a new representative of the <i>Ln</i>₃F[Si₃O₁₀] series could be synthesized by the reaction of Tm₂O₃, TmF₃ and SiO₂ (molar ratio: 1:1:3), applying an excess of CsBr as a fluxing agent in gas-tightly sealed platinum crucibles for eight days at 750 °C, and designed to yield Tm₃F₃[Si₃O₉] or Cs₂TmF[Si₄O₁₀]. …”

Scintillation and radioluminescence mechanism in β-Ga2O3 semiconducting single crystals by A.J. Wojtowicz, M.E. Witkowski, W. Drozdowski, M. Makowski, Z. Galazka

“…At the same time, residual Fe and Ir are ubiquitous uncontrolled impurities leached from the Ir crucibles used to grow large bulk crystals by the Czochralski method.For these experiments, we selected four samples cut from the Czochralski grown 2-cm diameter β-Ga2O3 single crystal boules; one with a reduced Fe content, two unintentionally Fe- and Ir-doped (UID) with lower and higher Fe content, and one doped with Mg.We find that steady-state radioluminescence spectra measured at temperatures between 10 and 350 K are dominated by the UV emission peaking at about 350–370 nm. …”
