A Self-Deliverable H₂O₂-Responsive Tocopherol Dimer for Enhanced Antioxidant and Liposomal Delivery

Molecules
Oxidative stress induced by excessive hydrogen peroxide (H2O2) is a critical pathological factor in skin aging, inflammatory disorders, and photodamage. While tocopherol (TCP) is a gold-standard antioxidant in cosmetics, its potential in H2O2-responsive ...

Universality in bosonic dimer-dimer scattering [PDF]

Physical Review A, 2011
Bosonic dimer-dimer scattering is studied near the unitary limit using momentum-space equations for the four-particle transition operators. The impact of the Efimov effect on the dimer-dimer scattering observables is explored and a number of universal relations is established with high accuracy.

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Flexibility and Dynamicity Enhances and Controls Supramolecular Self‐Assembly of Zinc(II) Metallogels

Advanced Functional Materials, EarlyView.
Zinc(II) coordination complexes with tunable aryloxy‐imine ligands exhibit controllable supramolecular self‐assembly into hierarchical fibrous structures. Coordination‐driven stacking, not π–π interactions, enables gelation, dynamic assembly/disassembly, and enhanced nanomechanical properties.

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

Advanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Dimeric Cinchona alkaloids [PDF]

Molecular Diversity, 2015
Nature is full of dimeric alkaloids of various types from many plant families, some of them with interesting biological properties. However, dimeric Cinchona alkaloids were not isolated from any species but were products of designed partial chemical synthesis.

Photoswitching Conduction in Framework Materials

Advanced Functional Materials, EarlyView.
This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

4-(3-Methylphenyl)-3-[(3-methyl-5-phenyl-1H-pyrazol-1-yl)methyl]-4,5-dihydro-1H-1,2,4-triazole-5-thione

IUCrData, 2017
The title compound, C20H19N5S, adopts a `contorted' conformation and the dihedral angle between the heterocyclic rings is 86.54 (6)°. In the crystal, complementary N—H...N hydrogen bonds form centrosymmetric dimers, which generate R22(14) loops.
