Surface adsorption is one of the methods of CO2 capture which has the ability to be recycled, save energy, have high stability, corrosion resistance, and implemented on industrial scale.
Using agricultural wastes as carbon adsorbents and economic and effective sources in adsorption can help reduce waste and preserve land, increase the productivity of agricultural resources, reduce CO2, and protect the environment. The importance of cheap agricultural wastes (biomass) such as bamboo waste, olive stones, peanut shells, walnut shells, sugarcane bagasse, cork, coffee grounds, etc., in CO2 adsorption, as well as their properties and performance, was investigated and solutions were also introduced to increase the adsorption capacity. The studied wastes show adsorption capacities of 0.083-26.4 mmol/g under different conditions. The development of new and sustainable technologies, optimization of processes and increasing public awareness are the main goals of this research. Agricultural wastes have high adsorption potential due to their porosity and suitable surface chemistry and are environmentally friendly.

The isothermal adsorption curves of pure CH4, CO2, and H2S on zeolite were simulated in a pressure range of 0-200 kPa at the temperature of 298, 323 and 348 K. The heat of adsorption analysis indicated that the physical adsorption has occurred. The simulation results showed a good agreement with experimental data and the average relative error of simulated results in 298 K for those gases were reported as 18.31%, 6.6%, and 9.8%, respectively. The isotherm of dual and triple combinations of these gases has been studied in the composition range of 70-90% of CH4. Results indicate that the tendency of chabazite for adsorption of H2S is much more than two other gases, because of its high polarity. In addition, results report that the selectivity of CO2 and H2S on chabazite in dual and triple gas mixtures are almost 2 and 4, respectively.

In this research, to achieve better biocompatibility, the addition of some chemical groups to carbon nanotube was studied using molecular dynamic simulation, which resulted in improved targeted drug delivery performance by surface modification. Also, to evaluate the effect of functional groups, first, the nanostructure without functional group along fluorouracil anticancer drug was investigated. Among the analyzes used to investigate the drug-carbon nanotube interaction with the POPE lipid bilayer membrane in the aqueous medium, we can mention the mean squared displacement, etc that Among these, the analysis of the radial distribution function to compare the water concentration around carbon nanotube and Mass center distance analysis was performed to evaluate the stability of the drug inside the carbon nanotube and then the diffusion coefficients of the carbon nanotube-membrane were compared with different chemical agents through the mean squared displacement. From the results, it was found that the binding of tetraethylene glycol increases the concentration of water around the nanotube as well as the stability of the loaded drug. However, the presence of tetraethylene glycol Led to a decrease in the diffusion coefficient of the nanocarrier.
