Exploration of the Phytochemical and Antidiabetic Properties of Teucrium polium: A Natural Asset for Type 2 Diabetes Management

ChemistryOpen, EarlyView.
Teucrium polium shows antidiabetic activity with its phytochemical composition and biological activities. The essential oil is rich in carvacrol, thymol, γ‐terpinene, and o‐cymene, while the aqueous and hydroethanolic extracts are characterized by poliumoside, verbascoside, isorhamnetin‐3‐O‐rutinoside, and apigenin‐7‐rutinoside. Antioxidant activity is

In Situ Surface Reconstruction and Carbon Encapsulation for High‐Performance Pt‐Lean Catalysts beyond Conventional Core–Shell Designs

Small, EarlyView.
A one‐step in situ fabrication produces Pt‐segregated nanoparticles encapsulated in porous carbon shells. This design drastically reduces Pt content while maintaining high oxygen reduction reaction activity and long‐term durability. The catalyst meets DOE targets even at ultralow Pt loading, presenting a practical pathway toward cost‐effective, high ...

Hole Doping Effects on Spin-gapped Na2Cu2TeO6 via Topochemical Na Deficiency

, 2006
We report the magnetic susceptibility and NMR studies of a spin-gapped layered compound Na2Cu2TeO6 (the spin gap $\Delta\sim$ 250 K), the hole doping effect on the Cu2TeO6 plane via a topochemical Na deficiency by soft chemical treatment, and the ...

Subnanometric Platinum–Germanium Clusters for Efficient Propane Dehydrogenation Catalysis

Small, EarlyView.
Pt─Ge alloy clusters are regioselectively encapsulated within the sinusoidal channels of pure silica MFI zeolite (PtGe@MFI). The developed Pt─Ge alloy clusters exhibit exceptional performance with 36‐fold higher activity than the most stable catalyst ever reported and twice its stability, and with comparable activity to and 21‐fold higher stability ...
