The consentaneous model of the financial markets exhibiting spurious nature of long-range memory

open access: yes, 2018
It is widely accepted that there is strong persistence in the volatility of financial time series. The origin of the observed persistence, or long-range memory, is still an open problem as the observed phenomenon could be a spurious effect.

Metal‐Organic Frameworks Facilitating Complexation for Long‐Cycle Zinc‐Bromine Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The organic ligands (imidazole and benzimidazole) from the decomposed zinc ZIF‐62 is proposed to further improve the Br2 complexing ability of the mature complexing agent (i.e., N‐methyl‐N‐ethyl pyrrolidinium bromide (MEP) ionic liquid). The synergistic effect between Im/BIm of the decomposed ZIF‐62 toward bromine species and MEP toward bromine species,
