Advanced Science, EarlyView.A rational architectural design of hierarchical, CNT‐interwoven hollow carbon microclusters unlocks and stabilizes a unique monoclinic Co3Se4‐mediated conversion–insertion pathway for potassium storage. This structural confinement effectively guides the reaction kinetics and accommodates severe mechanical strain.

Clifford analysis on the hyperbolic unit ball.
, 2004 In this thesis we consider a projective model for the hyperbolic unit ball, realized as the manifold of rays inside the future cone in the real orthogonal space R1,m, i.e. the flat Minkowksi space-time. Using Clifford algebras it is possible to define a Clifford algebra structure on this manifold, and this structure enables us to define the Dirac ...

On the penalized obstacle problem in the unit half ball
Electronic Journal of Differential Equations, 2010 We study the penalized obstacle problem in the unit half ball, i.e. an approximation of the obstacle problem in the unit half ball. The main result states that when the approximation parameter is small enough and when certain level sets are ...

Advanced Science, EarlyView.A serum‐free, air–liquid interface organotypic slice culture model preserves human post‐mortem corpus callosum tissue, successfully recovering from slicing trauma to reflect the donor's underlying disease state. Pairing label‐free Coherent anti‐Stokes Raman scattering (CARS) microscopy with k‐means clustering enables objective, high‐resolution ...
