Much of the research effort focused on the impacts of elevated CO2 on marine algae but very little work was done on freshwater algae, or on freshwater algal viruses. In this paper, we studied the impacts of elevated CO2 on the infection of a freshwater cyanobacterium (wild Leptolyngbya sp.) by cyanophage PP that have a wide distribution in China. In a 12-month experiment, logarithmic-phase host...

The interaction between CO2 and ultrathin ZnO supported on Au(111) has been studied using temperature programmed desorption (TPD) and density functional theory (DFT) calculations. We find that CO2 binds weakly on the planar ZnO bilayer and trilayer surfaces, desorbing at T = 130 K. CO2 binds more strongly at the steps formed between ZnO bilayers and trilayers, desorbing at T = 285-320 K dependi...

Volumetric techniques were employed to study the adsorption of CO2 on a purified multi-wall carbon nanotubes (MWNT’s) sample, as a mesoporous material, at isothermal conditions of 288, 293 and 298 K and pressures ranging from 30 to 150 kPa. Langmuir, Freundlich and Sips equations were used to represent the isotherms. Also the parameters of these fitted isotherm models have been determined. The ...

in this study the hardness swct was calculated with b3lyp,hf method and 3-21g,6-31g,6-311g basis set .then it was investigated with the best method(b3lyp) and basis set(6-31g) to study the adsorption effects co2 on the hardness of swcnt with gap homo-lumo in two shape: horizontal, vertical and top-center-bridge and we also provide the effects of co2 adsorption on the electronic properties(dos) ...

Nitrogen-doped hierarchical mesoporous carbon is synthesized via molecular coassembly and polymerization of a rationally designed pyrrole derivative via softtemplating with a triblock copolymer in solution, followed by mild carbonization at 350 C and chemical activation at 500 C. The nitrogen-rich porous carbon possesses 5.8 wt% N and has a high surface area of 942 m g with hierarchically dis...

Copper trimesate (Cu-BTC) MOF has been pointed out as a promising adsorbent for separating carbon dioxide from methane. However, MOF’s need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped bodies reduces their adsorption performance. In this work, Cu-BTC tablets provided by BASF are evalu...

The problem of reducing CO2 emissions in the atmosphere is indirectly related to the potential storage options in different environments in the earth's crust. One of the promising possibilities for reducing emissions of carbon dioxide (CO2) into the atmosphere is the geological storage of CO2 in deep, unminable coal seams. Measurements of the CO2 adsorption of 10 lignite samples from the Velenj...

As a new branch of MOFs which are composed of biocompatible metal ions and organic ligands, bio-metal-organic frameworks (bio-MOFs) have attracted much attention recently. Bio-MOFs feature multiple Lewis basic sites which have strong interaction with CO2 molecules, thus they have great potential in the separation and purification of gas mixtures containing CO2. In this work, molecular simulatio...

In this study, N-containing pitch-based activated carbons (NPCs) were prepared using petroleum pitch with a low softening point and melamine with a high nitrogen content. The major advantage of the preparation method is that it enables variations in chemical structures and textural properties by steam activation at high temperatures. The adequate micropore structures, appropriate chemical modif...

As part of our efforts to model enhanced coalbed methane recovery and CO2 sequestration in coalbeds, we have investigated the pure adsorption isotherm behavior of five dry coals namely, Illinois #6, Wyodak sub-bituminous, Pocahontas, Beulah Zap, and Upper Freeport coal. Using a volumetric technique, isotherms of pure methane, nitrogen, CO2 and ethane were measured at a temperature of 328.15 K (...
