Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

open access: yesAdvanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

DFT and TD-DFT investigation of calix[4]arene interactions with TFSI− ion [PDF]

open access: yesHeliyon, 2019
Understanding the interactions of the calix[n]arene molecules with a variety of invited chemicals entities is getting very important. In this context, we have studied a new host-guest such as the interaction of the calix[4]arenes with the bis (trifluoromethylsulfonyl) imide TFSI- ion.

Non-associative Deformations of Geometry in Double Field Theory [PDF]

open access: yes, 2014
Non-geometric string backgrounds were proposed to be related to a non-associative deformation of the space-time geometry. In the flux formulation of double field theory (DFT), the structure of mathematically possible non-associative deformations is ...

In‐Situ Growth of 2D MOFs as a Molecular Sieving Layer on SnS2 Nanoflakes for Realizing Ultraselective H2S Detection

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The ultraselective H2S detection of the ZIF‐L/SnS2 heterostructure is demonstrated. The introduction of 2‐dimensional (2D) breathable ZIF‐L results in a substantial increase in H2S selectivity attributable to the molecular sieving effect, which impedes the permeation of gases with large kinetic diameters and high polarity.
