Next‐Generation Carbon‐Based Anodes for Alkali Metal‐Ion Batteries: Recent Progress on Biphenylene and Emerging Materials

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Recent advances in carbon‐based anodes for alkali metal‐ion batteries are critically reviewed, with emphasis on biphenylene and other emerging carbon allotropes. Biphenylene exhibits exceptional theoretical electrochemical properties beyond conventional graphite, highlighting its strong potential as a next‐generation anode material once scalable ...

Competing Charge Transport Pathways: A Spirobifluorene‐Based Molecular Loop

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A rigid molecular loop integrating a spirobifluorene (SBF) core with a cycloparaphenylene (CPP) moiety provides two distinct transport channels. Through‐space spiroconjugation and radial π‐conjugation along a CPP backbone coexist within a single molecule.

Resolution Approaches Toward Enantiopure Planar Chiral 7‐bromo‐4‐hydroxy [2.2]paracyclophane

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This work describes access to both enantiomers of planar chiral 7‐bromo‐4‐hydroxy [2.2]paracyclophane through direct resolution of the racemate using an L‐isoleucine‐derived chiral auxiliary or through resolution of 4‐hydroxy [2.2]paracyclophane, followed by regioselective bromination.

A General Stereochemical Model for Grignard Additions to α‐Alkoxy Nitrones: Density Functional Theory Evidence for an Intrinsic α‐Chelation‐Controlled Pathway

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A comprehensive DFT conformational study of Grignard additions to α‐alkoxy nitrones reveals that the reaction proceeds through a dinuclear α‐chelated transition structure in which the nitrone oxygen coordinates two magnesium centers. Other common additives, such as zinc dichloride, boron trifluoride, and dimethylaluminum chloride, were also studied ...

Coated and Immobilized Polysaccharides‐Based Stationary Phases for Planar Metallocenes Enantioseparation in Liquid Chromatography

open access: yesELECTROPHORESIS, EarlyView.
This study examined 21 new ferrocene and ruthenocene derivatives, including those with planar and central chirality. Their stereochemical behavior was examined using UV‐detected normal‐phase liquid chromatography. Under fixed conditions, eight polysaccharide‐based chiral stationary phases were tested using n‐heptane combined with either 2‐propanol or ...

Plant‐Derived Extracts Disrupt Biofilm Formation and Quorum Sensing in Yersinia enterocolitica: Insights From GC‐MS and Molecular Docking

open access: yesFood Chemistry International, EarlyView.
The graphical abstract represents how natural plant products that preferentially target the specific receptors of quorum sensing could be developed to combat biofilms linked to Yersinia enterocolitica using the potent abilities of protein–ligand complexes with high docking scores.

Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis

open access: yesLaser &Photonics Reviews, EarlyView.
We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...
