Advanced Functional Materials, EarlyView.This work utilizes poly(heptazine imides) as a model system to demonstrate how fine‐tuning the crystal structure influences the photocatalytic properties of layered carbon nitrides in the hydrogen evolution reaction. In particular, the nature of rotational defects and the hydration shell of cations are key contributors to enhanced hydrogen evolution ...

Spinor algebra and null solutions of the wave equation
, 2010 In this paper we exploit the ideas and formalisms of twistor theory, to show how, on Minkowski space, given a null solution of the wave equation, there are precisely two null directions in $\ker df$, at least one of which is a shear-free ray ...

AdS Twistors for Higher Spin Theory [PDF]
AIP Conference Proceedings, 2005 We construct spectra of supersymmetric higher spin theories in D=4, 5 and 7 from twistors describing massless (super-)particles on AdS spaces. A massless twistor transform is derived in a geometric way from classical kinematics. Relaxing the spin-shell constraints on twistor space gives an infinite tower of massless states of a ``higher spin particle'',

Advanced Functional Materials, EarlyView.Free‐standing undulating graphene oxide (GO) modular tapered pipes fabricated based on the Marangoni effect and viscosity control are modular tubular structures that effectively utilize the lamination process between GO films. This novel tubular GO structure allows for the realization of various forms through the assembly of identical modules ...

Advanced Functional Materials, EarlyView.A scalable one‐step copolymerization strategy is developed to produce low‐cost microporous ion exchange membranes that boost both the efficiency and lifespan of flow batteries. When combined with organic electrolytes in aqueous systems, these membranes enable safe and cheap flow battery energy storage, supporting the widespread integration of renewable

Integrability in gravity from Chern-Simons theory
Journal of High Energy PhysicsThis paper presents a new perspective on integrability in theories of gravity. We show how the stationary, axisymmetric sector of General Relativity can be described by the boundary dynamics of a four-dimensional Chern-Simons theory.
