Relating the combinatorial materials chip mapping to the glass-forming ability of bulk metallic glasses via diffraction peak width

Ze Liu, Cai Chen, Yuanxun Zhou, Lanting Zhang, Hong Wang

Summary: This study attempts to address the gap in cooling rates between thin film deposition and bulk metallic glass (BMG) casting by correlating the glass-forming range (GFR) determined from combinatorial materials chips (CMCs) with the glass-forming ability (GFA) of BMG. The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.

Summary: Even small changes in physicochemical properties of nanoforms (NFs) can influence their environmental fate and hazard. Testing and characterizing each individual NF will not be feasible due to the large number of new materials being developed. Targeting the most relevant form of the NF for a given exposure is important for efficient risk assessment. In aquatic systems, functional fate processes play a key role in determining the exposure relevant form of NFs. Grouping of NFs and read-across based on functional fate pathways can be justified by considering the shared fate and hazard profile. A new Integrated Approaches to Testing and Assessment (IATA) is presented, focusing on dissolution, dispersion stability, chemical transformations, and the contribution to toxicity from particles and dissolved components. This IATA can be used as a template for future in vivo kinetic assessments.
