MODIFIED HZSM-5 AND H-MORDENITE ZEOLITES AS SUPPORTS FOR PLATINUM CATALYST

مجلة النهرين للعلوم الهندسية, 2019
Bifunctional Pt/HZSM-5 and Pt/HMOR catalysts were prepared and applied to the isomerization of n-Hexane. Catalysts containing 0.3wt% Pt on both catalysts with potentially high acidity were prepared by impregnation method.

Prominent Movement Disorders in RNU2‐2‐Related Spliceosomopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Pediatric movement disorders often overlap with neurodevelopmental diseases, suggesting shared molecular mechanisms. Variants in small nuclear RNA (snRNA) genes encoding spliceosome components have recently been associated with neurodevelopmental disorders, termed “RNUopathies.” We analyzed genome sequencing data from 14 patients with ...

Modulation of Pt electron transfer via engineered ultra-thin TiO2-Al2O3 interfaces for coke-resistant methane dry reforming

Nature Communications
Dry reforming of methane (DRM) is plagued by rapid catalyst deactivation, primarily due to carbon deposition exacerbated by exposed Al2O3 surfaces in conventional mixed-phase supports.

A 'plug & play' microreactor for rapid screening of the activity of a catalyst on different supports

, 2010
A ‘plug & play’ micro reactor is demonstrated for the rapid screening of the activity of a heterogeneous catalyst on different types of supports. The micro reactor can hold three interchangeable plates with each the same catalyst support.

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

Advanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Does shape matter? FEMDEM estimations of strength and post failure behaviour of catalyst supports [PDF]

, 2017
The combined finite-discrete element method (FEMDEM) implemented in Solidity is employed to simulate the effects of geometrical features and loading orientation on the pre- and postfailure behaviour of catalyst supports.

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

Advanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the
