Polyethylene (PE) is indispensable materials in daily lives. The catalyst is necessary to produce PE. Ziegler-Natta catalysts were mostly used to produce PE which consisted of MgCl2/TiCl4 system. Polyethylene particle was reported to replicate the shape o... see more

Abstrak Aspal porus merupakan campuran beraspal yang memiliki rongga udara yang besar yang menyebabkan aspal porus memiliki nilai stabilitas yang rendah. Untuk meningkatkan nilai stabilitas diperlukan bahan tambah lain yang memiliki potensi seperti l... see more

The classical stability analysis is used to examine the combined effect of viscoelasticity and the second sound on the onset of porous medium ferroconvection. The fluid and solid matrix are assumed to be in local thermal equilibrium. Considering the bound... see more

This study was conducted to determine the role of thermal treatment on the crystallinity and pore characteristics of porous ceramic, which was prepared from natural clay (NC) and chitosan (CS) biopolymer using the gel casting method. CS was used as an env... see more

In heavily populated urban areas, high rainfall can cause inundation and even flooding because the catchment area is decreasing. To reduce rainwater runoff and increase groundwater recharge, porous concrete can be used in housing area, in parking lots and... see more

Simulations were carried out to visualize the ratio of granular attachment to porous surfaces. This simulation uses a uFlex three-dimensional simulation using three sizes of porous surface systems in the condition of the smallest human pores and the most ... see more

The main objective of this paper is to focus on a numerical study of unsteady boundary layer flow of Williamson Nanofluids over a heated permeable stretching sheet embedded in porous medium in the presence of viscous dissipation. A mathematical modeled wh... see more

The heat and mass transfer characteristics of the nonlinear, unsteady, radiative MHD boundary layer slip flow of a chemically reacting fluid past an infinite vertical porous plate are taken into account in this study. The effect of physical parameters are... see more

Porous silicon (PSi) has developed for many applications such as gas and humidity sensors. Various methods are available to fabricate PSi, and electrochemical anodization is common due to low cost and easy use. Current density, etching/anodization time, t... see more
