NMR Spectroscopy for Studying the Selective Etching of Ti3AlC2 to Ti3C2Tx MXene Using Hexafluorosilicic Acid

open access: yesSmall Methods, EarlyView.
27Al NMR spectroscopy is introduced as a method to detect the etching of Ti3AlC2 to Ti3C2Tx MXene. Soluble aluminum species produced during etching were identified by sampling the etching supernatant during the reaction. Using a combination of 27Al and 19F NMR spectroscopies, a new acid etchant, hexafluorosilicic acid, was shown to be free of HF or ...

Converting Binary Floating‐Point Numbers to Shortest Decimal Strings: An Experimental Review

open access: yesSoftware: Practice and Experience, EarlyView.
ABSTRACT Background When sharing or logging numerical data, we must convert binary floating‐point numbers into their decimal string representations. For example, the number π might become 3.1415927. Engineers have perfected many algorithms for producing such accurate, short strings.

Epistemological Implications of a System—Theoretical Understanding for Sustainability Models

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT In the sense of the Sustainable Development Goals (SDGs), global efforts to create a sustainable society will not be sufficiently successful under the current geopolitical and socio‐economic trends. For this reason, recent sustainability research has increasingly focused on systemic coherence, the subject of cognition, and psychological and ...
