Solvation Entropy as a Lever for Steering the Macroscopic Properties of a Functional Supramolecular Helical Polymer

open access: yesAngewandte Chemie, Volume 138, Issue 3, 16 January 2026.
The structural transition between the two fully‐characterized states of a supramolecular helical hydrogen‐bonded polymer (represented as blue and light pink stacks) can be predictably varied over 85 K by changing the nature and amount of cosolvent; entropy of solvation (schematized as solvents of different sizes) is the main lever to tune the ...

Microstructure, mechanical, and thermal properties of compositionally complex (Hf,Zr,Nb,Ti)B2‒LaB6 ceramics

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Novel compositionally complex borides, (Hf,Zr,Nb,Ti)B2 and (Hf,Zr,Nb,Ti)B2‒LaB6, were fabricated using spark plasma sintering process. (Hf,Zr,Nb,Ti)B2‒LaB6 exhibits a dual‐phase microstructure, in which (Hf,Zr,Nb,Ti)B2 is a primary phase with the hexagonal structure and LaB6 is a secondary phase with a cubic structure.

The regional evolution of a dryland fluvio‐aeolian and lacustrine succession in response to allocyclic forcing: insights from the Early Permian Cutler Group, Utah, USA

open access: yesSedimentology, Volume 73, Issue 2, Page 297-354, February 2026.
ABSTRACT Preserved allocyclic signatures in the rock record often reflect basin‐scale climatic variability and serve as key proxies for correlating ancient dryland successions. The notion of climate cyclicity, however, remains largely untested on regionally constrained, outcrop‐calibrated studies.

Ab Initio Molecular Dynamics Study of Quadrupolar Spin Relaxation in an Ionic Liquid

open access: yesJournal of Computational Chemistry, Volume 47, Issue 3, 30 January 2026.
This study presents a methodology for describing the relaxation of nuclear spins (with I > 1/2), applicable to ionic liquids of a general nature. Based on ab initio molecular dynamics, we demonstrate the importance of explicit solvation in calculating the relaxation times of the quadrupolar mechanism.
