Accuracy of ab initio methods in predicting the crystal structures of metals: review of 80 binary alloys [PDF]

Calphad 29, 163-211 (2005), 2005
Predicting and characterizing the crystal structure of materials is a key problem in materials research and development. We report the results of ab initio LDA/GGA computations for the following systems: AgAu, AgCd, AgMg, AgMo*, AgNa, AgNb*, AgPd, AgRh*, AgRu*, AgTc*, AgTi, AgY, AgZr, AlSc, AuCd, AuMo*, AuNb, AuPd, AuPt*, AuRh*, AuRu*, AuSc, AuTc ...

The Thermophysical Properties of TcO₂

Crystals
Technetium-99 is a highly radioactive isotope with a long half-life that is common in nuclear waste. It volatizes at a low temperature, which poses a significant challenge to the clean-up and containment processes.

Impeding 99Tc(IV) mobility in novel waste forms

Nature Communications, 2016
Technetium-99 retention in spinel-containing glass is a promising strategy for radioactive waste management, but volatility is still an issue. Here, the authors show that doping magnetite with 1st row transition metals enhances technetium retention by ...

Consecutive Case Series of Melanoma Sentinel Node Biopsy for Lymphoseek Compared to Sulfur Colloids [PDF]

, 2018
Introduction: Sentinel lymph node biopsy (SLNB) is an important adjunct in the staging of patients with melanoma. Preoperative lymphoscintigraphy (LS) with radiolabeled isotopes is essential to localize sentinel nodes for removal.
