Bifunctional Characteristics of Al2O3 supported Ni in the HI Decomposition of Sulfur-Iodine Process

MATEC Web of Conferences, 2016
The Sulfur-Iodine process is in need of catalytic reactor for HI decomposition because the HI decomposition reaction rate is very slow. Nickel as an alternative catalyst for platinum was investigated in this study.

First-Principle Investigation of the Interface Properties of the Core-Shelled L1₂-Al₃M (M = Sc, Zr, Er, Y) Phase

Crystals, 2023
The interface structure and segregation behavior of L12-Al3M (M = Sc, Zr, Er, Y) phases were investigated based on first-principles calculations. The results showed that the order of the thermodynamically stable interface was Al3Zr/Al > Al3Sc/Al > Al3Er/

Assessment of prevalence of work-related musculoskeletal disorders among welders in the shipyard industry in Malaysia [PDF]

E3S Web of Conferences, 2019
Work-related musculoskeletal disorders (MSDs) are often experienced by welders in the shipyard industry. A study was conducted in one of the shipyards in Malaysia to identify the prevalence of work-related MSDs among welders and the factors attributed to

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

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.
