Multi‐performance‐based optimal design method of locally resonant metastructures for structural control

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 25, Page 4193-4211, 20 October 2025.
Abstract Locally resonant metamaterials (LRMs) have been extensively investigated for wave attenuation; however, the interaction between their bandgaps and a structure's modal dynamics remains relatively unexplored. To address this gap, a design framework is presented to quantify and enhance the structural control performance enabled by LRM‐induced ...

Spatially Resolved Observation of Ferroelectric‐to‐Paraelectric Phase Transition in a Two‐Dimensional Halide Perovskite

open access: yesAdvanced Materials, Volume 37, Issue 33, August 21, 2025.
Temperature‐dependent nanoscale ferroelectric domain evolution and the ferroelectric‐to‐paraelectric phase transition in 2D halide perovskites is visualized using piezoresponse force microscopy. The phase transition initiates locally below the Curie temperature and progressively propagates as paraelectric regions expand.

Reconstructing general plane quartics from their inflection lines [PDF]

open access: yes, 2018
Let $C$ be a general plane quartic and let ${\rm Fl}(C)$ denote the configuration of inflection lines of $C$. We show that if $D$ is any plane quartic with the same configuration of inflection lines ${\rm Fl}(C)$, then the quartics $C$ and $D$ coincide ...

Synthesis of Beta‐Enaminoketones and Enaminoesters Catalyzed by Brønsted Acids Ammonium Chloride and Glycine Hydrochloride

open access: yesChemistrySelect, Volume 10, Issue 21, June 4, 2025.
Beta‐diketones and beta‐ketoesters were reacted with aliphatic or aromatic amines to give stable enaminones, catalyzed by either ammonium chloride or glycine hydrochloride, as inexpensive and nontoxic catalysts. The reactions were conducted under neat conditions with short work‐up, catalyst recovery and a few demonstrations of reaction telescoping to ...

A tmQCD mixed-action approach to flavour physics

open access: yes, 2017
We discuss a mixed-action approach in which sea quarks are regularised using non-perturbatively ${\rm O}(a)$ improved Wilson fermions, while a fully-twisted tmQCD action is used for valence quarks.

Inhibition of Bone Morphogenetic Protein Signaling Prevents Tau Pathology in iPSC Derived Neurons and PS19 Mice

open access: yesAnnals of Neurology, Volume 97, Issue 4, Page 657-672, April 2025.
Objective Many neurodegenerative disorders share a common pathologic feature involving the deposition of abnormal tau protein in the brain (tauopathies). This suggests that there may be some shared pathophysiologic mechanism(s). The largest risk factor for the majority of these disorders is aging, suggesting involvement of the aging process in the ...

Addressing the Reuse of Deep Eutectic Solvents in Li‐Ion Battery Recycling: Insights into Dissolution Mechanism, Metal Recovery, Regeneration and Decomposition

open access: yesChemSusChem, Volume 17, Issue 20, October 21, 2024.
Extensive reuse of deep eutectic solvent should be ensured when applied in the Li‐ion battery recycling process. In each key step of recycling, including metal dissolution, recovery, and DES regeneration, decomposition and consumption occur, hindering DES reuse and thus undermining the feasibility of the entire recycling process. Abstract Deep eutectic
