Additive Manufacturing of Alumina‐Reinforced Elastomers
Advanced Engineering Materials, EarlyView.Vat‐photopolymerized elastomers reinforced with platelet‐shaped alumina exhibited preferential orientation, reduced porosity, and significantly enhanced mechanical performance. A 3 wt% platelet loading increased tensile strength from 12.4 to 45.7 MPa, highlighting the critical role of filler morphology in elastomeric VPP composites.

Non-linear partial differential equations in conformal geometry
, 2002 In the study of conformal geometry, the method of elliptic partial differential equations is playing an increasingly significant role. Since the solution of the Yamabe problem, a family of conformally covariant operators (for definition, see section 2) generalizing the conformal Laplacian, and their associated conformal invariants have been introduced.

A design tool for globally developable discrete architectural surfaces using Ricci flow
Japan Architectural Review, 2023 This paper presents an approach for the design of discrete architectural surfaces that are globally developable; that is, having zero Gaussian curvature at every interior node.

Conformally invariant differential equations and projective geometry
Journal of Functional Analysis, 1981 AbstractWe combine harmonic analysis on certain pseudo-Riemannian symmetric spaces with results on conformally invariant linear and non-linear differential equations. This gives in many cases part of the decomposition of certain representations of the conformal group of a manifold when restricted to the isometry group.

Conformal Dirichlet-Neumann Maps and Poincaré-Einstein Manifolds
Symmetry, Integrability and Geometry: Methods and Applications, 2007 A conformal description of Poincaré-Einstein manifolds is developed: these structures are seen to be a special case of a natural weakening of the Einstein condition termed an almost Einstein structure.

Superconformal quantum mechanics on Kähler cones
Journal of High Energy Physics, 2020 We consider supersymmetric quantum mechanics on a Kähler cone, regulated via a suitable resolution of the conical singularity. The unresolved space has a u(1, 1|2) superconformal symmetry and we propose the existence of an associated quantum mechanical ...
