Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Chemical agents to control biofilm formation in step 1 of care—Toothpastes and mouthwashes/concepts and challenges

Periodontology 2000, EarlyView.
Abstract Maintaining optimal oral hygiene is important for overall oral care, ensuring the well‐being of teeth and their surrounding tissues. In addition, it promotes fresh breath and a pleasing smile. A key element of oral self‐care is the daily use of toothpaste during regular brushing.

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Two‐Stage, Sequential Aryne Carboiodanation Enabled by Mesomeric Priming

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Two‐stage, sequential insertion of arynes into the carbon–iodine(III) bond of benziodoxole (BX) compounds is achieved by judicious choice of the BX/aryne pair in the first step, generating a mesomerically activated aryl‐BX primed for a second, discrete aryne insertion. This metal‐free strategy enables programed access to biaryl‐BXs and modular entry to

Carbamate‐Directed peri‐CH Alkynylation: Application to the Synthesis of Zethrenes and Pyranthrenes

ChemistryEurope, Volume 4, Issue 5, May 2026.
The Rh(III)‐catalyzed regioselective alkynylation of 1‐pyrenyl and 1‐naphthyl carbamates with bromoacetylenes enables the selective installation of an alkyne at the peri position of readily accessible amino‐substituted polycyclic aromatic hydrocarbons (PAHs).

Beyond the Solid Solution: Ordered Enantiomerically Unbalanced Packing in Surface‐Confined Tetrahelicene Monolayers

Chirality, Volume 38, Issue 5, May 2026.
Racemic dicyanotetrahelicene exhibits coverage‐dependent self‐assembly on Ag(111), transitioning from spontaneous chiral resolution at low coverage to a dense mixed phase at monolayer saturation. While submonolayer deposition produces extended homochiral domains, full coverage yields a compact, long‐range ordered lattice with an enantiomerically ...

First Access to Tetraazadiindenopyrenes via Selective Pyrrole Cyclization of Phenyl‐Substituted Tetraazapyrene Derivatives on Au(111)

Small Science, Volume 6, Issue 5, May 2026.
Contrary to long‐held expectations of on‐surface chemistry, tetraphenyl‐substituted tetraazapyrene undergoes selective pyrrole cyclization and C–C coupling on Au(111), forming a distinctive N‐doped nanographene consisting of fused tetraazadiindenopyrene and phenanthrene cores with embedded pyridinic and graphitic nitrogen.
