Equilibrium gels of limited valence colloids

, 2017
Gels are low-packing arrested states of matter which are able to support stress. On cooling, limited valence colloidal particles form open networks stabilized by the progressive increase of the interparticle bond lifetime.

Peptide Sequence Programmed Piezoelectric Response by Supramolecular Self‐Assembly

Advanced Science, EarlyView.
In this study, hydrophobic tripeptides are explored as building blocks for stable piezoelectric crystals. Tripeptides with phenylalanine at the central position self‐assembled into uniform, thermally stable crystals. Piezoresponse force microscopy reveals a high effective piezoelectric coefficient of 24.0 pC N−1, attributed to asymmetric molecular ...

Catalytic Amyloids: Turning Fibrils Into Biocatalysts

Chemistry – A European Journal, EarlyView.
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as

Molecular basis for a pore block of Tentonin 3 expressed in HEK293 cells by a conopeptide, NMB‐1

British Journal of Pharmacology, EarlyView.
Background and Purpose Tentonin 3 (TTN3/TMEM150C) is a mechanosensitive ion channel that plays critical roles in mechanotransduction processes. TTN3 forms a tetramer with a predicted rectangular shape and a central pore. A conotoxin ρ‐TIA and its synthetic analog, noxious mechanosensation blocker 1 (NMB‐1), were initially developed to inhibit slowly ...

Guanidinium Like‐Charge Ion Pairing and Oligoarginine Aggregation in Water by Nuclear Magnetic Resonance, Cryo‐Electron Microscopy, and Molecular Dynamics

Aggregate, Volume 7, Issue 2, February 2026.
This study shows that guanidinium cations weakly attract one another in water and form like‐charge contact ion pairs. From NMR, we determine the free energy of ion‐pair formation to be ≈${\approx }$ –0.5 kJ mol−1${\rm mol}^{-1}$, consistent with all‐atom MD simulations and DFT calculations.
