This research work investigates the application of KOH impregnated jackfruit leaf powder to remove Nickel from wastewater. The removal characteristics of Nickel from wastewater was investigated under various operating variables like contact time, adsorbent dosage, initial metal concentration, solution pH, temperature and stirring speed. The results showed that the KOH impregnated jackfruit leaf...

A sonochemistry-based synthesis method was used to produce nanocrystalline nickel oxide powder with ≈ 20 nm average crystallite diameter from Ni(OH)(2) precursor. Ultrasound waves were applied to the primary solution to intensify the Ni(OH)(2) precipitation. Dried precipitates were calcined at 320°C to form nanocrystalline NiO particles. The morphology of the produced powder was characterized b...

A 26-year-old female chemist formulated polymers and coatings usually using silver ink particles. When she later began working with nickel nanoparticle powder weighed out and handled on a lab bench with no protective measures, she developed throat irritation, nasal congestion, "post nasal drip," facial flushing, and new skin reactions to her earrings and belt buckle which were temporally relate...

Abstract Cu-Ni-Si alloys have been widely used in electronics and electrical industries.The preparation method of alloy was not limited to smelting, powder metallurgy has also attracted the attention many researchers. In this study, were prepared using hot-pressed sintering elemental copper powders, which nickel silicon powders as raw materials. The results show that, when sintering, there no N...

The aim of this study is to investigate the microstructure and wear properties nickel (Ni) matrix boron carbide (B4C) carbon nanofiber (CNF)-reinforced composite materials. Microstructure phase composition composites manufactured by powder metallurgy (PM) method were determined SEM-EDS XRD analysis. While hardness values Vickers measurement method, their using pin-on-disc method. SEM images sho...

Aluminium (Al)/Aluminium alloy composites are emerging as very promising materials, especially in the fields of aerospace and automotive for their various attractive and technically demanding properties. Discontinuously reinforced aluminium metal matrix composites with reinforcements as nanoparticles of ceramics in general and carbon nanotubes in particular have emerged as the forerunner for a ...
