Abstract Universal behavior in far-from-equilibrium systems is driven by interactions between transport processes and noise structure. The Kardar-Parisi-Zhang (KPZ) framework predicts that extensions incorporating conserved currents or temporally correlated noise give rise to distinct growth morphologies and universality classes, yet direct experimental realization has remained elusive.

Aqueous Phase Semihydrogenation of Alkynes over Ni-Fe Bimetallic Catalysts Bimetallic Ni-Fe catalysts (Ni/Fe, 1:1, 1:3, and 3:1) are synthesized and explored for their catalytic activity in semihydrogenation of internal alkynes using H2 gas in water-ethanol solution. Our findings revealed that over Ni1Fe3 catalyst high diastereoselectivity for Z-alkenes with a high conversion for a wide range of internal alkynes can be achieved at moderate reaction temperature (40 ºC).
