Microtextural and surface chemical heterogeneities of activated carbons (AC) have been studied to see their distinctive role for the adsorption of CO2, CO and N2 at 25 °C and up to 850 Torr. Not only the microtextural properties influence the adsorption of the gases, particularly CO2, but the chemical surface heterogeneity also plays a significant role for CO2 adsorption. The volume of ultramicropores < 7 Å is of predominantly importance in high CO2 adsorption at pressures above 30 Torr. However, the average size of micropores and their size distribution, and the chemical surface heterogeneity are much more critical at the Henry’s law region (< 30 Torr). The latter could be well characterized by the amount and Henry constant of CO2 adsorption at the low pressures, the Toth model parameters, the change in CO2/ CO and CO2/ N2 selectivities with respect to pressure, the amount of CO from the thermal decomposition, and the direct probing of very strong basicity sites using a technique that is the temperature-programmed desorption of CO2 adsorbed. All of them are consistent with the difference in the energetic nonuniformity between ACs studied, except for the last measure whose results could be reasonably explained when combining with the microtextural heterogeneity.

This study was performed to grasp the introduction of Korean wild evergreen broad-leaved tree, Ternstroemia gymnanthera, as a plant of indoor garden, and to figure out the light-adaptability under the four types indoor lighting and to provide the introduction plan. The experimental plants, Ternstroemia gymnanthera was purchased from the farmhouse in Jeju-do as a year plant, and it was experimented after the acclimation in the glass-green house of general farm of Gyeongnam National University of Science and Technology for 40 days. The experiment was performed for 1 year more from September 10, 2014 to September 30, 2015. The results of the experiment are as follows. When Ternstroemia gymnanthera is introduced as a plant of the indoor garden, the optical fiber, fluorescent lamp, and LED light in order are suitable to introduce as the proper lighting. In the case of the three-wave light, the growth and development was the worst among the 4 introduced lighting systems, therefore, the growth of Ternstroemia gymnanthera under the three-wave light was incongruous generally. The withering appearance was existed seriously by 500lux. Some leaves were fallen off, but generally smooth growth and development was done in the range of the 1,000lux to 2,000lux. The best intensity for the growth was under the condition of the 1,000lux. When the fluorescent lamp, and LED light are introduced, the most proper luminous intensity is the 2,000lux. When the optical fiber is introduced, the most efficient intensity is the 1,000lux. Generally the smooth growth and development is done under the more luminous intensity. As the result, the wild Ternstroemia gymnanthera is the species of tree to substitute the Ficus benghalensis, or Ficus retusa which is the foreign species, as a central tree or upper tree as well as pot tree, and it is expected to introduce sufficiently as a plant of the indoor garden.
