Dalam bidang industri, katalis memegang peranan penting khususnya untuk meningkalkan kinerja proscs reaksi kimia. Bcrbagai upaya dilakukan unluk meningkalkan aktivitas dan juga siabilitas kalalis. Salah satunya adalah unluk rcaksi hidrogcnasi CO2 mcnjadi mctanol yang memiliki arli pentlng dalam kcbuluhan industri saat ini. Dibutuhkan katalis yang aktif agar pmses reaksi kimia antara C01 yang cenderung stabil dan hidrogen berlangsung lebih cepat.
Dari sekian banyak aplikasi ultrasonik pada proses rekayasa kimia, aplikasi ultrasonik yang sedang banyak dikembangkan ...

The purpose of this study is to obtain the Young's Modulus (elastic property) of Cu6Sn5 phase by using ultrasonic technique and composite theory. Alloy with the following composition (weight percent = wt%): 15.00% Cu and 85.00% Sn was fabricated by casting method. Phases identification were determined by using X-ray Diffraction (XRD), Differential Scanning Calorimeter (DSC), and Scanning Electron Microscope (SEM) + EDAX (Energy Dispersive X-ray Analysis). A non destructive technique is preferable evaluation method for ...

Jacobsite nanomagnetic particles with various size can be easily synthesized by using coprecipitation method. Samples are categorized into two synthesis condition, which is nonultrasonic assisted and ultrasonic assisted process. Samples are characterized with various methods to give understanding on their structure. Annealing process gave significant effect on the structure of the particles, thus provides better crystallinity on the annealed samples. The study shows that upon the annealing temperature of 300OC for four hours on nanomagnetic ...
