Doping graphene by adsorption of polar molecules at the oxidized zigzag edges
, 2009 We have theoretically investigated the electronic and magnetic properties of graphene whose zigzag edges are oxidized. The alteration of these properties by adsorption of $\mathrm{H_{2}O}$ and $\mathrm{NH_3}$ molecules have been considered.

A Crystalline Ylide‐Stabilized Stibenium Cation
European Journal of Inorganic Chemistry, EarlyView.The isolation of a stibenium cation stabilized by two thiophosphinoyl‐tethered ylide groups is reported. The cation is accessible via salt metathesis of the metalated ylide with SbCl3 and features CSb single bonds, with lone pairs remaining localized at the ylidic carbon atoms.

From Phosphinimines to Four‐Membered SiCPN Cations: Insights Into N–Si Bonding and Ring Strain
European Journal of Inorganic Chemistry, EarlyView.Sterically tuned N‐silyl phosphinimines enable four‐membered SiCPN cations. Hydride abstraction yields cyclic cations for Me and iPr substituents at silicon, while tBu gives a protonated intermediate. Multinuclear NMR spectroscopy, X‐ray crystallography, thermochemical density functional theory investigations, and natural bond orbital analyses reveal ...

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application
European Journal of Organic Chemistry, EarlyView.Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Understanding β-Hydride Eliminations from Heteroatom Functional Groups [PDF]
, 2011 Using density functional theory, we investigated detailed aspects of the quintessential organometallic process, β-hydride elimination (BHE). In general, we find that most BHE processes from alkyl functional group β-atoms are facile, while BHE processes ...

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Obesity and its metabolic complications, such as insulin resistance and cognitive decline, remain a global health challenge. Green tea (Camelia sinensis) and ω‐3 polyunsaturated fatty acids (PUFAs) are recognized for their antioxidant, anti‐inflammatory, and neuroprotective properties.

Laser &Photonics Reviews, EarlyView.Van der Waals ferroelectric NbOX2 thin films exhibit phonon‐resonance enhanced electro‐optic responses, 332 pm/V at 3.1 THz (NbOI2) and 192 pm/V at 3.7 THz (NbOBr2), the highest among vdW materials, and show 4% non‐resonant SHG modulation together with resonant phonon‐enhancement under a 150 kV/cm THz pump.
