In this work, carbon composite papers (CCP) were successfully produced by mixing 80 wt% carbon derived from coconut coir and 20 wt% binder (ethylene vinyl acetate and polyethylene glycol). The CCPs were prepared with two different forms of carbon material... see more

Metode sequential injection analysis-gas diffusion (SIA-GD) dengan kolorimeter RGB (red, green, blue) yang sederhana dan cepat telah berhasil dikembangkan untuk penentuan tiosianat. Metode ini didasarkan pada proses oksidasi tiosianat menjadi sianida dala... see more

As kerogen is the main organic component in shale, the adsorption capacity, diffusion and permeability of the gas in kerogen plays an important role in shale gas production. Based on the molecular model of type II kerogen, an organic nanoporous structure ... see more

Underground coal gasification (UCG) proceeds generally in the presence of an ash layer on coal (or char) surface. The ash layer increases the mass transfer resistance of O2 to the gasification surface, which may become the limiting step of whole process. ... see more

One of the factors that can increase the surface transfer property for gas diffusivity apart from the membrane material in PEMFC is the porosity of the gas diffusion layer material affecting species mass distribution at the electrodes. The present study s... see more

The oxygen vacancies (VO) play an essential role in the gas-sensing mechanism of semiconductor devices. A diffusion equation is established to describe the VO behaviors during a cooling process based on the model of gradient-distributed oxygen vacancies. ... see more

Ion layer gas reaction (ILGAR) method allows for deposition of Cl-containing and Cl-free In2S3 layers from InCl3 and In(OCCH3CHOCCH3)3 precursor salts, respectively. A comparative study was performed to investigate the role of Cl on the diffusion of Cu fr... see more

To make inside of the municipal solid waste (MSW) landfill aerobic as much as possible is thought to be preferable for promoting waste stabilization, reducing pollutant's load in leachate, minimizing greenhouse gas emission and shortening post-closure-car... see more

Carbon monoxide (CO) gas is one of the harmful and toxic gases derived from the residue of blasting and incomplete combustion of mining equipment machines in underground mines. CO gas dilution is carried out with the intention of unsafe conditions in the ... see more
