Solitary wave complexes in two-component mixture condensates
, 2004 Axisymmetric three-dimensional solitary waves in uniform two-component mixture Bose-Einstein condensates are obtained as solutions of the coupled Gross-Pitaevskii equations with equal intracomponent but varying intercomponent interaction strengths ...

Nonexistence of steady waves with negative vorticity
, 2020 We prove that no two-dimensional Stokes and solitary waves exist when the vorticity function is negative and the Bernoulli constant is greater than a certain critical value given explicitly.

Advanced Materials, EarlyView.Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Solitary Waves Bifurcated from Bloch Band Edges in Two-dimensional Periodic Media
, 2007 Solitary waves bifurcated from edges of Bloch bands in two-dimensional periodic media are determined both analytically and numerically in the context of a two-dimensional nonlinear Schr\"odinger equation with a periodic potential.

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts
Advanced Materials, EarlyView.An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Solitary-wave propagation and interactions for a sixth-order generalized Boussinesq equation
International Journal of Mathematics and Mathematical Sciences, 2005 We study the solitary waves and their interaction for a six-order generalized Boussinesq equation (SGBE) both numerically and analytically. A shooting method with appropriate initial conditions, based on the phase plane analysis around the equilibrium ...

A scalar nonlocal bifurcation of solitary waves for coupled nonlinear Schroedinger systems
, 2002 An explanation is given for previous numerical results which suggest a certain bifurcation of `vector solitons' from scalar (single-component) solitary waves in coupled nonlinear Schroedinger (NLS) systems.

Homoleptic and Heteroleptic Carbones L1‐C‐L2
Angewandte Chemie, EarlyView.DFT and CCSD(T) calculations reveal that heteroleptic carbones L₁–C–L2 are thermodynamically stable species even with a weakly binding donor such as N2. Bond strengths show no simple correlation with bond lengths. Weaker carbon‐ligand bonds in homoleptic complexes L1─C─L1 are mostly strengthened in heteroleptic carbons L1─C─L2, while stronger bonds L2 ...
