Polysulfone ultrafiltration membranes were fabricated using various sizes (20, 40, and 90-210 nm) of silver nanoparticles (nAg) blended in a dope solution. To characterize the performance properties prepared membranes, scanning electron microscopy (SEM), water contact angle, protein separation, flux, antibacterial tests conducted. The characterization results revealed that when nAg particles (20 into base polymer PSF, PSF/nAg membrane had lowest angle (58.5°) surface energy (110.7 mN/m)....
The essential oils of the leaves two Syzygium species commonly used as spices in Indonesia (Syzygium polyanthum and S. aromaticum) were analyzed by gas chromatography/mass spectrometry (GC/MS) evaluated for their minimum inhibitory concentration (MIC) against five food-borne microorganisms.The both plants obtained hydrodistillation method.The major constituents ofessential oil ofS.polyanthum cis-4-decanal (43.489%), 1-decyl aldehyde (19.752%), capryl (14.092%), while ofS.aromaticum p-eugenol...
Micromachining in the micro-electric discharge machining (μ-EDM) process requires high material-removal rate with good surface quality. Power-mixed μ-EDM, a modified by introducing specific powder into dielectric fluid, is among key inventions to achieving these requirements. This article presents review of implementation powder-mixed micro-EDM processes for microfabrication. Special attention was given influence characteristics, such as concentration, electrical conductivity, shape and size...
Purpose The purpose of this study is to investigate the influences extruder temperatures and raster orientations on mechanical properties polylactic-acid (PLA) material processed by using fused filament fabrication (FFF). Design/methodology/approach In research, PLA specimens were first printed with nozzle or 205°C, 215°C 225°C then evaluated in terms their physical, chemical properties. An appropriate temperature was selected based experiment used for printing other having various...
Material removal rate in electropolishing is often overlooked because this process generally addressed for surface finish; however, it paramount on metallic sheet machining possessed with intricate geometry. Electropolishing removes material from the of a workpiece based anodic dissolution process. The depends current density, electrolyte, strength magnetic field, polishing time and temperature. In study, three factors applied voltage, electrolyte composition field were evaluated using...
In electropolishing, the material removal rate is frequently neglected, as this process primarily focused on surface finish, and yet, it crucial for manufacturing metallic sheets. Solutions are required to enhance while maintaining quality. This work introduces an electropolishing technique that involves suspending ethanol in electrolyte solution employing a magnetic field during machining processes. The Taguchi approach utilized determine ideal parameters enhancing of SS 316L through L9...
