Fractal Geometry on Hyperbolic Manifolds
, 2006 In this survey we give a report on some recent results obtained in the studies of hyperbolic manifolds by means of fractal geometry. Emphasis has been put on results derived in the quantitative and qualitative fractal analysis of long term geodesic dynamics on hyperbolic manifolds.

On the Betti numbers of a hyperbolic manifold
Geometric and Functional Analysis, 1992 Let \(\Gamma\) be an arithmetic lattice in \(SO(n,1)\). If \(\Gamma\) is commensurable with the group of units of a quadratic form over a totally real field which has signature \((n,1)\) at one real place and is anisotropic at the remaining real places then it is shown in [\textit{J. J. Millson}, Ann. Math., II. Ser. 104, 235-247 (1976; Zbl 0364.53020)]

Enhancing Electrical Impedance Based Deformation Sensing with Dielectric Current Guide
Advanced Electronic Materials, EarlyView.This work introduces a dielectric‐based field manipulation strategy for electrical impedance tomography in soft robotics. By using silicone as a passive electric field guide, improved deformation sensing accuracy and reduced interference are achieved without embedding conductive components.

A Schwarz lemma of harmonic maps into metric spaces
Electronic Research ArchiveWe established a Schwarz lemma for harmonic maps from Riemannian manifolds to metric spaces of curvature bounded above in the sense of Alexandrov. We adopted the gradient estimate technique which was based on Zhang-Zhu's maximum principle. In particular,

Optimizing Lithium Nucleation Overpotential in Anode‐Free Garnet‐Based Hybrid Solid‐State Batteries
Advanced Energy Materials, EarlyView.A hybrid solid–liquid electrolyte approach using additives based on localized high‐concentration electrolyte with a trilayer garnet enables a stable, ionically conductive interphase for anode‐free solid‐state lithium batteries. Cu/Li half‐cells show 81% Coulombic efficiency over 300 cycles, while pouch cells retain 75% capacity after 400 cycles at 1C ...

Simple Detection of Imperfect Charge Extraction at Contacts – Application to Perovskite Solar Cells
Advanced Energy Materials, EarlyView.A novel analytical method is introduced to quantify imperfect charge extraction at solar cell interfaces using internal quantum efficiency measurements under weak and strong absorption. Applied to highly efficient perovskite solar cells, the method reveals imperfect interfacial collection, enabling rapid evaluation and detection of efficiency ...
