This study was conducted to develop a heat interception permeability aggregate pavement material that resists increase of air temperature and has permeability by decreasing pavement temperature of city in summer. For this study, a heat interception polymer binder mixed with heat interception material and polyurethane binder. And the study made heat interception permeability aggregate pavement material by mixing heat interception polymer binder. Using the materials, the study conducted flexural strength test and temperature reduction effect experiment. As the result, flexural strength was 5.43MPa average and the temperature reduction effect was effective up to maximum 16 degrees Celsius compared to current asphalt concrete.

In vivo nicotine is associated with Alzheimer's, Parkinson's and lung cancer. Diagnostic assays of these diseases depend on very low analytical detection limits. In this study, a sensitive analytical method was examined using a voltammetric graphite pencil electrode (GPE) and a modified carbon nanotube paste electrode (CNE). The optimum analytical conditions for both electrodes were compared using square wave anodic stripping voltammetry (SW) and cyclic voltammetry (CV) obtaining 400 sec accumulation time and oxidation peak. Under optimum parameters, the stripping working range of GPE was 5.0-40.0μg/L, CNE: 0.1-0.8 and 5-50μg/L. Quantification limits were 5.0μg/L for GPE and 0.1μg/L for CNE, while detection limits were 0.6μg/L for GPE and 0.07μg/L for CNE. A standard deviation of 10.0μg/L was observed for 0.064 GPE and 0.095 CNE (n = 12) using 400 sec accumulation time. The results obtained can be applied to non.treated urine and ex vivo biological diagnostics.
