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 ...

Algebraic dimension of twistor spaces
Mathematische Annalen, 1988 Associated to any self-dual Riemannian four manifold M is a twistor space. This is the set of all complex structures (compatible with the metric) on all tangent spaces to the manifold. It fibres over the manifold with fibres isomorphic to one dimensional complex projective space and is itself a complex manifold. The author proves: Theorem.

Advanced Functional Materials, EarlyView.Sustainable films with heterosymmetric structures, harmoniously integrating symmetry and asymmetry, are fabricated using cellulose nanocrystals and hydrophilic nanolignin via evaporation‐induced self‐assembly, which exhibit excellent multiple polarization optical properties.

On the moduli space of superminimal surfaces in spheres
International Journal of Mathematics and Mathematical Sciences, 2003 Using a birational correspondence between the twistor space of S2n and projective space, we describe, up to birational equivalence, the moduli space of superminimal surfaces in S2n of degree d as curves of degree d in projective space satisfying a ...

Anisotropic Shear Properties of Organic Interfaces in Bio‐composite Materials
Advanced Functional Materials, EarlyView.A novel cantilever design enables direct probing of shear properties at single organic interfaces within biocomposite prismatic ultrastructures. By decoupling lateral and torsional shear responses, the method reveals isotropic behavior in Atrina vexillum and pronounced anisotropy in Unio pictorum.

Carrollian $\mathscr Lw_{1+\infty}$ representation from twistor space
SciPost PhysicsWe construct an explicit realization of the action of the $\mathscr Lw_{1+∞}$ loop algebra on fields at null infinity. This action is directly derived by Penrose transform of the geometrical action of $\mathscr Lw_{1+∞}$ symmetries in twistor space ...
