Tribochemical Surface Modification of Silicon

Chemistry – A European Journal, EarlyView.
Mechanical scribing activates silicon surfaces by generating reactive sites that spontaneously graft alcohol‐, thiol‐, and alkyne‐terminated molecules under ambient conditions. Within 10 s, high‐coverage, electroactive organic layers form without light, heat, or applied voltage, offering a rapid tribochemical route to functional silicon interfaces for ...

Karrikins Regulate the Redox Balance and Sugar Metabolism of Postharvest Kiwifruit (Actinidia deliciosa)

Plants
Karrikins, a class of butenolide compounds derived from plant-derived smoke, positively regulate plant development and stress tolerance. However, their effects on postharvest fruit have scarcely been reported.

Efficient Light‐Driven Multi‐Electron Accumulation on Viologens by Molecular Control Over Photochemical Reaction Pathways

Chemistry – A European Journal, EarlyView.
Minimum structural changes, maximum output: By either utilizing a more oxidizing Ru(II) polypyridyl chromophore or by using a more reducing SED, the photocatalytic reduction of methyl viologen (MV2+) proceeds via a reductive quenching pathway. This not only significantly accelerates the overall photoreduction process but also allows accumulation of ...

MonoHER and ascorbate consumption rates.

, 2013
Consumption of monoHER and ascorbate in the incubation mixtures containing 50 µM monoHER, 1.6 nM HRP and 33 µM H2O2 in the presence of either 40 µM GSH, 40 µM ascorbate or both 40 µM GSH and 40 µM ascorbate. The incubation time was 5 minutes.

Nano MIPs (Molecularly Imprinted Polymers) Prepared From a “Frustrated” Gold Nanoparticle‐Based Pre‐Imprinting Matrix: Enhancing Binding Affinity and Selectivity

Chemistry – A European Journal, EarlyView.
A comparative study across ligand‐stabilized gold nanoparticles and surfactant micelles reveals that molecular imprinting strongly depends on the nanoplatform used for imprinting. “Frustrated” noncovalent interactions within the monolayer on gold nanoparticle surface can be exploited to improve both the binding affinity and selectivity for ...

Epigenetic Reprogramming via TET2 Prevents Medial Calcification and Restores Vascular Smooth Muscle Cell Identity

JACC: Basic to Translational Science
Summary: Vascular calcification arises from the osteogenic transdifferentiation of vascular smooth muscle cells (VSMCs) and is a hallmark of many cardiovascular pathologies.

Modulation of Epigenetic Control by Advanced Molecular Tweezers

Chemistry – A European Journal, EarlyView.
Tailored dimeric molecular tweezers recognize the DNA‐binding part of Histone H4 and interrupt the essential histone‐DNA interaction. ABSTRACT This work addresses the question if supramolecular systems can be tailored to interfere with posttranslational modifications (PTM) and epigenetics.

Exogenous Ergothioneine and Glutathione Limit Postharvest Senescence of Arugula

Antioxidants
Arugula is susceptible to postharvest deterioration. We tested the impact of exogenous antioxidant (i.e., ergothioneine and glutathione) dip solutions on arugula quality during storage at 4 °C or 10 °C for up to 17 days relative to a non-antioxidant ...

Targeting Cancer Cells With Self‐Assembled Ru‐Polysaccharide Photocatalyst for Visible‐Light‐Induced Activation of Prodrugs

Chemistry – A European Journal, EarlyView.
Self‐assembled photocatalyst Ru(Ada‐bpy)(bpy)2⊂HACD targets cancer cells and catalyzes the prodrug to drug upon exposure to visible light, providing spatially and temporally control in cancer cells. This strategy achieves efficient, controllable, and targeted activation of prodrugs within cancer cells, laying the foundation of effectively reducing the ...

Oxygen Depletion and the Role of Cellular Antioxidants in FLASH Radiotherapy: Mechanistic Insights from Monte Carlo Radiation-Chemical Modeling

Antioxidants
FLASH radiotherapy is a novel irradiation modality that employs ultra-high mean dose rates exceeding 40–150 Gy/s, far surpassing the typical ~0.03 Gy/s used in conventional radiotherapy.
