Advanced Energy Materials, EarlyView.Trace water is acting as a constructive mediator in 2LiCl–GaF3, markedly increasing ionic conductivity while reorganizing local coordination. Hydration creates localized Li+ solvation environments and partially dissociates ion pairs, enhancing Li‐ion mobility.

, 2008 We show that normal K3 surfaces with ten cusps exist in and only in characteristic 3. We determine these K3 surfaces according to the degrees of the polarizations.

Graded Rings and Special K3 Surfaces
, 2006 Many recent constructions of varieties, including the lists of K3 surfaces in Magma, use graded ring methods.We show how to apply the method using Magma and, as an application, construct 27 families of K3 surfaces that appear as degenerate cases of ...

Advanced Energy Materials, EarlyView.A hexagonal tunnel‐structured MoO3 is nanoparticulated via hydrothermal synthesis followed by ball‐milling. As a positive electrode in Ca and Mg batteries, it delivers superior capacity and structural reversibility, enabling divalent cation intercalation with minimal lattice distortion and no phase transitions.

On automorphisms of supersingular K3 surfaces
Osaka Journal of Mathematics, 1997 Let \(k\) be an algebraically closed field of positive characteristic, let \(X\) be a K3 surface and assume that there exists a fibration with elliptic fibres \(X\to{\mathbb{P}}^1\) with a section \(O\). The Mordell-Weil group of \(X\) is the group of \(k({\mathbb{P}}^1)\)-rational points of the generic fibre of \(X\to{\mathbb{P}}^1\), taking \(O\) as ...

Singular curves on K3 surfaces
, 2010 We investigate the Clifford index of singular curves on K3 surfaces by following the lines of [10]. As a consequence, we are able to deduce from [3] that Green’s conjecture holds for all integral curves on K3 ...

Regenerations and applications
Forum of Mathematics, SigmaChen-Gounelas-Liedtke recently introduced a powerful regeneration technique, a process opposite to specialization, to prove existence results for rational curves on projective $K3$ surfaces.

Rational Curves on K3 Surfaces
, 1998 We proved the existence of rational curves in every linear system on a general K3 surface and that all rational curves in the hyperplane class are nodal on a general K3 surface of small genus.

Twistor Spaces for Supersingular K3 Surfaces
, 2018 Thesis (Ph.D.)--University of Washington, 2018We develop a theory of twistor spaces for supersingular K3 surfaces, extending Artin's analogy between supersingular K3 surfaces and complex analytic K3 surfaces.

SYMMETRIC SYMPLECTIC HOMOTOPY K3 SURFACES
, 2011 This is the pre-published version harvested from ArXiv.A study on the relation between the smooth structure of a symplectic homotopy K3 surface and its symplectic symmetries is initiated. A measurement of exoticness of a symplectic homotopy K3 surface is
