WebThe present work focuses on the chemical and electrochemical characteristics of binary mixtures of CHP and organic N-heterocycles as a model system. A set of binary mixtures composed of CHS and the N-heterocycles are prepared for comparison and the results are discussed in light of fundamental acid base chemistry. 2 Experimental 2.1 Materials ... WebOct 3, 2024 · Superprotonic phase transition in CsHSO4 allows fast protonic conduction, but only at temperatures above the transition temperature of 141 °C (Tc). Here, we preserve the superprotonic conductivity of CsHSO4 by forming a binary CsHSO4-coordination polymer glass system, showing eutectic melting. Their anhydrous proton conductivities below Tc …
