Interface‐Mediated Catalysis for Improved Hydrogen Storage in Reactive Hydride Composites

Advanced Materials, EarlyView.
Catalyst–hydride interfaces are engineered in Co@C‐ and Ni@C‐modified 2LiH + MgB2 reactive hydride composites to accelerate hydrogen uptake and release. Multiscale scattering, in‐situ synchrotron radiation powder x‐ray diffraction and density functional theory calculations reveal the structural and electronic origin of the catalytic enhancement ...

A System with Two Integrable Hierarchies [PDF]

Journal of the Physical Society of Japan, 1999
Summary: By assuming the symmetry group and using the inverse method, we find an integrable system which is constructed from superposition of two hierarchies of integrable equations. The authors discuss the SU(2) and SL(2,\(\mathbb{R}\)) cases in detail.

A NEW EXPANDING INTEGRABLE HIERARCHY OF KAUP–NEWELL HIERARCHY

Modern Physics Letters B, 2006
A higher loop algebra is constructed which is devoted to establish an isospectral Lax pair. Integrable coupling of the well-known Kaup–Newell hierarchy is obtained by using a relation of direct sum between two sub-algebras. As in the reduction case, an integrable coupling of a generalized MKdV equation is presented. The approach presented in the paper

Integrable Couplings of the Coupled Burgers Hierarchy

Communications in Theoretical Physics, 2004
Summary: In this letter, a new loop algebra \(\tilde{G}\) is constructed, from which a new isospectral problem is established. It follows that integrable couplings of the well-known coupled Burgers hierarchy are obtained.
