Highly Selective Oxidation of Hydroquinones to Quinones With Dibenzoyl Peroxide

, 1989
Dibenzoyl peroxide in the presence of bases such as 1,8-diazabicyclo[5.4.0] undec-7-ene or potassium carbonate oxidizes hydroquinones to quinones cleanly without oxidizing alcohol, aldehyde or benzylic groups.

Surface boron modification of an anthraquinone‐2‐sulfonate‐intercalated NiFe layered double hydroxide film for durable anodic operation in chloride‐containing alkaline electrolyte

Bulletin of the Korean Chemical Society, EarlyView.
A mild NaBH4$$ {\mathrm{NaBH}}_4 $$ treatment condenses boron onto binder‐free NiFe−LDH$$ \mathrm{NiFe}-\mathrm{LDH} $$ films on Ni foil. In chloride‐containing alkali at 200mAcm−2$$ 200\ \mathrm{mA}\ {\mathrm{cm}}^{-2} $$, the boron‐modified film lasts 87 h versus 13 h for untreated film.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...
