The Anatomical Record, EarlyView.Abstract The crania of leporid lagomorphs are uniquely fenestrated, including the posterior cranial bones and the lateral portion of the maxilla. The functional significance of the highly fenestrated rostrum has received considerably little attention, despite being absent in other mammalian herbivores with a long rostrum.

Aromatic Diester Anolytes for Nonaqueous Redox Flow Batteries
Batteries &Supercaps, EarlyView.Owing to their extended π‐conjugation 2,2′‐bipyridyl aromatic diesters are stable in singly‐ and doubly‐reduced states. In a redox flow battery a high battery voltage of 2.82 V can be realized and a capacity a capacity retention of 99.5% per cycle for 260 cycles.

ChemistryEurope, EarlyView.Ring‐opening metathesis polymerization offers access to borane polymers with tunable Lewis acidity, environmental stability, and luminescence. The Lewis acid strength approaches that of B(C6F5)3 when R = Cl and Ar = C6F5, high stability is ensured with chlorophenyl or naphthyl pendent groups (Ar = ClPh, Np), and strong emission is achieved with a ...

Intramolecular N···F Pnictogen Bond Mitigates the Explosive Behavior of Azido‐L‐Phenylalanines
ChemistryEurope, EarlyView.An intramolecular N···F pnictogen bond is the key for the chemical stabilization of the fluorinated azido‐L‐phenylalanines, mitigating the risk of explosion and thus facilitating the handling and storage of these materials. Organic azides are versatile intermediates but are plagued by intrinsic instability and potential explosiveness. Here, it is shown

ChemistryEurope, EarlyView.The cis‐2,3‐bis(trifluoromethyl)cyclopropyl chemotype is introduced. The steric demand of this motif is intermediate between that of the heptafluoroisopropyl and prefluorotertbutyl groups; yet, it induces significantly less lipophilicity than these due to its facial polarity.

ChemistryEurope, EarlyView.The linear and nonlinear (chir)optical properties of four oligoamide foldamers with different donor groups are studied by means of time‐dependent density functional theory calculations. It is shown that stronger donors yield larger hyperpolarizabilities due to low‐lying charge–transfer states. The agreement with the experiments concerning the key bands
