The study develops a sustainable gasket material from a mixture of treated coconut shell cellulose and epoxy matrix. Design expert statistical software was used for optimizing the mechanical properties. Chemical and thermal stability tests were performed to validate the gaskets' performance in industrial applications.

Modulation of Oxygen Vacancies on Cu/ZnO by Promoter for Higher Alcohol Synthesis From Syngas
Oxygen vacancy (Ov) formation is modulated by promoter incorporation. Additional metal atoms are inserted into ZnO tetrahedral sites in CZA and CZG, thereby promoting vacancy growth. In contrast, a CuCr2 bimetallic phase is produced in CZC, suppressing ZnO defects. Enhanced Ovs promote ethanol formation.

The wear of materials in hydraulic transport pipelines
Bibliography: leaves 60-68.The hydraulic transportation of particulate solids through pipelines results in wear of the pipeline walls. The lifetime of the pipeline is determined by this rate of material loss and is therefore critical to the designer. Due
