“…From previous studies [6,7] which do not take anisotropy into account, we know that a CO van der Waals energies while observed geological phenomena indicate strong preference of CO 2 molecule over CH 4 molecule in surface adsorption. In the present work, we explore the physical aspect of the underlying mechanism in order to understand the difference in interaction behavior of CO 2 and CH 4 molecules with surfaces with the focus being anisotropy in the electric polarizabilities of the respective molecules (see FIG.…”

In order to understand why carbon dioxide (CO2) and methane (CH4) molecules interact differently with surfaces, we investigate the Casimir-Polder energy of a linearly polarizable CO2 molecule and an isotropically polarizable CH4 molecule in front of an atomically thin gold film and an amorphous silica slab. We quantitatively analyze how the anisotropy in the polarizability of the molecule influences the van der Waals contribution to the binding energy of the molecule.

“…Although, cellulose produced from plant is chemically the same with that one produced from bacteria (β-1,4-glucans), the degree of polymerization (13,000 to 14,000 for plant cellulose and 2000-6000 for bacterial cellulose), structure, and some properties are different (Jonas and Farah, 1998). Therefore, among other polymers, cellulose has been one of the most studied as a membrane material due to its abundance and high mechanical strength (Thiyam et al, 2015). In 1970, Gantzel and Merten studied the permeability of cellulose acetate membranes.…”

“…Purification of biogas aims to improve its quality by separating non-methane gases, specifically carbon dioxide, which can reduce the heating value and the combustion efficiency [8]. Decreasing the concentration of carbon dioxide can be done by physical adsorption, which is the simplest method to immobilize of biomolecules such as CO 2 which are bounded to the surface through weak bonds such as van der Waals forces [9]. There are three types of adsorbents, including elements that contain carbon (activated carbon and graphite), polymer elements (porous polymer matrix), and elements that contain oxides (silica gel and zeolites) [10].…”

Biogas is produced by the digestion of anaerobic bacteria to the degraded organics waste. However, the application of biogas is not effective because it consists of impurities such as carbon dioxide (CO2), hydrogen sulfide (H2S), water vapor (H2O), and other impurity gases. Physical Adsorption is the simplest method of immobilization of biomolecules such as CO2 which is attached to the surface through the weak bonds like van der waals forces. One of the physical adsorption to reduce CO2 levels in biogas is to use brick powder. The goal of this research is to determine the effectivity of brick powder as a purification adsorbent to the reduction of CO2 levels using the 23 factorial design method. The application of 200 and 400 grams brick powder adsorbents, with the biogas flow rate of 1 and 2 liters/minute, was researched at intervals 5 and 20 minutes, for the CO2 concentration data and heating values of biogas. Gas Chromatography (GC) is used to determine the concentration of adsorption gases especially CO2 and CH4. The results showed that the biggest effectivity reduction in CO2 concentration is 59,28%. The Increasing of brick powder adsorbent mass caused the decrease of CO2 concentration in the biogas purification. Brick is a porous material containing SiO2 – Al2O3, so it has the ability to form Van Der Waals bonding forces with CO2.
