Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

Advanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

Large degree asymptotics of orthogonal polynomials with respect to an oscillatory weight on a bounded interval [PDF]

, 2014
We consider polynomials p^w_n(x) that are orthogonal with respect to the oscillatory weight w(x)=exp(iwx) on [?1,1], where w>0 is a real parameter. A first analysis of p^?_n(x) for large values of w was carried out in connection with complex Gaussian ...

A reconciliation of the Pryce-Ward and Klein-Nishina statistics for semi-classical simulations of annihilation photons correlations

Physics Letters B
Two photons from the ground state para-positronium annihilation are emitted in a maximally entangled singlet state of orthogonal polarizations. In case of the Compton scattering of both photons the phenomenon of quantum entanglement leads to a measurable

Achieving High Spatial Resolution Transmission Electron Microscopy Studies in Closed Liquid Cells

Advanced Materials, EarlyView.
Achieving high spatial resolution is important for resolving nanoscale dynamic processes and structural transformations in liquid environments, yet remains challenging in liquid cell transmission electron microscopy (LCTEM). This review highlights key strategies, including mitigating membrane bulging, displacing or redistributing local liquid ...

Modified moments and orthogonal rational functions [PDF]

, 2004
In a series of articles [9, 10, 11] about the numerical computation of orthogonal polynomials on a subset of the real line, Gautschi shows that computing orthogonal polynomials starting from the moments µk = x k dµ(x) of the measure is generally an ill-

Reactivity‐Guided Janus Graphene With Asymmetric Interfacial Electrostatics for Tunable Charge Transport

Advanced Materials, EarlyView.
Stepwise dual‐side functionalization creates covalent Janus graphene with chemically and electrostatically asymmetric interfaces. The resulting nonadditive surface‐potential response and pronounced charge‐transport modulation demonstrate a versatile route for tailoring the electronic properties of graphene.

Surface Functionalization Modulates Collective Cell Behavior Near Topological Defects Induced by Topographical Patterning

Advanced Materials Interfaces, EarlyView.
Strongly adhered cells align with concentric circular ridges and exhibit predominantly tangential motion, whereas weakly adhered cells fail to follow topographical guidance and display enhanced radial inward motion. ABSTRACT Living cells establish long‐range orientational order through collective alignment, giving rise to topological defects whose ...
