Advanced Functional Materials, EarlyView.A roll‐to‐roll exfoliation method is demonstrated that preserves the crystallographic alignment of anisotropic 2D materials over large areas, enabling scalable fabrication of directional electronic and optoelectronic devices. Abstract Anisotropic 2D materials such as black phosphorus (BP), GeS or CrSBr, exhibit direction‐dependent optical and ...

A note on radial nonlinear Schrodinger systems with nonlinearity spatially modulated
Electronic Journal of Differential Equations, 2008 First, we prove that for Schrodinger radial systems the polar angular coordinate must satisfy $heta'= 0$. Then using radial symmetry, we transform the system into a generalized Ermakov-Pinney equation and prove the existence of positive periodic ...

Twisting asymptotic symmetries and algebraically special vacuum solutions
Journal of High Energy PhysicsIn this paper, we study asymptotic symmetries and algebraically special exact solutions in the Newman-Penrose formalism. Removing the hypersurface orthogonal condition in the well studied Newman-Unti gauge, we obtain a generic asymptotic solution space ...

Conservation laws and symmetries of semilinear radial wave equations
Journal of Mathematical Analysis and Applications, 2007 Classifications of symmetries and conservation laws are presented for a variety of physically and analytically interesting wave equations with power onlinearities in n spatial dimensions: a radial hyperbolic equation, a radial Schrodinger equation and its derivative variant, and two proposed radial generalizations of modified Korteweg--de Vries ...

Generating Cell Surface Nucleated Hydrogels with an Artificial Membrane‐Binding Transglutaminase
Advanced Functional Materials, EarlyView.Cell‐based therapies require advanced strategies to enhance cell delivery and bioactivity. Cell membrane engineering offers an avenue to impart new functions to delivered cells to boost their viability and function. Here, an artificial membrane‐binding transglutaminase is generated and biophysically characterized.

Demystification of animal symmetry: symmetry is a response to mechanical forces
Biology Direct, 2017 ᅟ Symmetry is an eye-catching feature of animal body plans, yet its causes are not well enough understood. The evolution of animal form is mainly due to changes in gene regulatory networks (GRNs). Based on theoretical considerations regarding fundamental
