Design and Fabrication of Complex Micro–Nano Structures for Osteogenesis Interfacing in 3D

open access: yesSmall Structures, Volume 7, Issue 8, August 2026.
The graphical abstract demonstrates the 3D Si structure platforms and the cell interactions. (left) Si structures including wine glass‐, obelisk‐, and pillar‐shaped structures are fabricated at wafer scale. (right) Compare to planar Si substrate, the wine glass‐shaped structures demonstrated promising cellular behavior and osteogenesis guidance by ...

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

open access: yesChemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Synthesis of Benzopyran Atropisomers via Electrophilic Halogenation

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 27, 17 July 2026.
We report a halogenation‐based method for the synthesis of axially chiral benzopyrans, tolerating diverse substituents and halogens (Br, Cl, and I). A double bromination gives bisbenzopyrans with two stereogenic axes. Preliminary enantioselective conditions yield benzopyran atropisomer with up to 56% ee.

Polysilane‐Supported Nickel as an Efficient Catalyst for the Hydrogenation of Aromatic Compounds†

open access: yesChinese Journal of Chemistry, Volume 44, Issue 14, Page 2277-2282, 15 July 2026.
A Ni/Si catalyst obtained from the reaction of poly(monohydro)silane with Ni(cod)2 serves as an effective heterogeneous catalyst for the hydrogenation of arenes under reaction conditions that are significantly milder than those required for conventional nickel‐based catalysts such as Raney nickel.

Hybrid Aminoferrocenes With Nitrate Esters for In Situ Peroxynitrite Generation: Complex Interplay Between Redox Chemistry, NO‐Donor Reactivity, and Aminoferrocene Activation Influences In Vitro Anticancer Activity

open access: yesChemBioChem, Volume 27, Issue 13, 14 July 2026.
Aminoferrocene‐based prodrugs represent a promising class of redox‐active anticancer agents that can be selectively activated in oxidative cellular environments. However, activation of these systems typically relies on reactive oxygen species (ROS) and is therefore inefficient in intracellular compartments with low ROS levels, such as the cytoplasm. In
