Anthraquinone‐Based organo‐CAPodes for High‐Performance Iontronic Logic Circuits

Batteries &Supercaps, Volume 9, Issue 11, November 2026.
A novel CAPode concept based on organic redox‐active small molecule is proposed (organo‐CAPodes) along with a gated CAPode (organo‐G‐CAPode) device. The anthraquinone‐based proof‐of‐concept CAPode reaches a high rectification ratio II of 96% and the G‐CAPode a capacitance suppression to 0.6% and an amplification of 1000% relative to the original ...

Intrinsic Antimicrobial Properties of a Novel Silorane‐Based Material for Orthopedic Applications

Journal of Biomedical Materials Research Part A, Volume 114, Issue 11, November 2026.
ABSTRACT One of many drawbacks of PMMA bone cement used to secure orthopedic implants is that its surface is highly susceptible to bacterial attachment and biofilm formation. In an effort to find alternative materials, we focused on silorane‐based polymers previously developed for use in dental composites.

Cononsolvency‐Assisted Fabrication of Hydrogels and Microgels With Tunable Porosity, Diffusivity and Stiffness

Macromolecular Rapid Communications, Volume 47, Issue 21, 6 November 2026.
The cononsolvency of poly(dimethyl acrylamide‐co‐hydroxyethyl acrylamide) copolymers in water‐acetonitrile mixtures enables the synthesis of hydrogels with finely tuned porosity. Optimized for droplet‐based microfluidics, this approach facilitates the fabrication of porous microgels with tunable mechanical and diffusion properties, offering precise ...

Synthesis and Characterization of Monodisperse Sulfonic Acid‐Functionalized Hollow Polymer Microspheres Using Precipitation Polymerization as Recyclable Solid Acid Catalysts

Macromolecular Rapid Communications, Volume 47, Issue 21, 6 November 2026.
Monodisperse sulfonic acid‐functionalized hollow polymer microspheres were prepared via precipitation polymerization using a cleavable phenylsulfonate‐containing styrene dimer. Core‐shell particles were converted into hollow structures through selective core cleavage and functionalization.

Flavin Catalysts in Organic Synthesis

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Synthesis of hydroquinone monomethyl ether from hydroquinone and methanol over heteropolyacids supported on clay: kinetics and mechanism

, 2005
Hydroquinone mono methyl ether (HMME) is industrially a very important anti-oxidant, produced by environmentally undesirable routes. In the current studies, HMME was synthesized from hydroquinone and methanol catalyzed by various solid acids using ...

Prospective, Double‐Blinded, Randomized Study of Topical Almond Oil and Tretinoin on the Appearance of Facial Wrinkles

Journal of Cosmetic Dermatology, Volume 25, Issue 11, November 2026.
ABSTRACT Background Retinoids are widely used in the treatment of wrinkles and photoaging. However, they frequently cause irritation and increase sun sensitivity. As a result, there has been greater emphasis for the evaluation of alternative ingredients and naturally derived ingredients.
