Direct Resin Composite and Lithium Disilicate Endocrowns in Severely Compromised Endodontically Treated Molars: A Two‐Year Randomized Controlled Trial

International Endodontic Journal, Volume 59, Issue 11, Page 2383-2401, November 2026.
ABSTRACT Aim This randomized controlled superiority trial aimed to compare the clinical performance (restoration survival, clinical quality, and patient satisfaction) of direct resin composite and lithium disilicate endocrown restorations in structurally compromised endodontically treated molars.

Synthesis of Nitrogen‐Containing Heterocyclic Scaffolds and Applications in Scaffold Hopping: Development of an Aripiprazole Analog

ChemMedChem, Volume 21, Issue 20, 28 October 2026.
A series of 12 novel fused [6,6] saturated and unsaturated nitrogen bicycles is synthesized in three to five steps and expands the CRAFT library's fragment space. A 2,6‐naphthyridin‐3‐ol core replaces the dihydroquinolinone scaffold of aripiprazole, a scaffold‐hopping strategy.

Mechanistic Insights Into Sustainable Catalytic Pyrolysis of Biomass‐Derived Ferulic Acid: The Role of Alumina Regeneration

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

Silica‐Supported Mononuclear Methyl‐Platinum Complexes Stabilized by Trimethylphosphine—Synthesis, Structure, and Reactions Under Reducing Conditions

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
The article describes the synthesis and molecular transformations of a silica‐supported bis(phosphine)methylplatinum(II) complex under reactive (H2, CO) and inert gas atmospheres. The focus lies on the stabilizing effect of the sterically non‐demanding trimethylphosphine ligand, which alters the reactivity of the surface sites, compared to other ...

Inverse Vulcanized Sulfur Polymer Composites From Poultry‐Industry Products and Lignocellulosic Biomass Waste

Journal of Applied Polymer Science, Volume 143, Issue 39, October 15, 2026.
This work explores the use of various fillers, including eggshell powder, feather meal, peanut hulls, and sawdust to reinforce a base binder GFS90 (comprised of 90 wt.% sulfur, 5 wt.% chicken fat, and 5 wt.% sunflower oil). The resulting composites showed impressive compressive strengths ranging from 15.3 to 36.2 MPa, making them a potential ...
