The Effect Of Catalyst Support On The Decomposition Of Methane To Hydrogen And Carbon. [PDF]
, 2004 Decomposition of methane into carbon and hydrogen over Cu/Ni supported catalysts was investigated. The catalytic activities and the lifetimes of the catalysts were studied. Cu/Ni supported on Ti02 showed high activity and long lifetime for the reaction.

Numerical Simulation of Hindered Diffusion in γ-Alumina Catalyst Supports
Oil & Gas Science and Technology, 2017 By employing multi-scale random models of γ-alumina, we have studied the influence of porosity, grain aspect ratio and aggregation state on the effective diffusion coefficient.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
