| 3 | Flexible and disposable paper-based gas sensor using reduced graphene oxide/chitosan composite显示文摘Nitrogen dioxide(NO_(2))is a representative toxicant in air pollution that mostly arises from the exhaust gas released by automobiles.It is related to various respiratory diseases such as pneumonia and sudden infant death syndrome.Additionally,because the toxicity of nitrogen dioxide is high in overpopulated areas(i.e.,a capital or metropolis),the development of simple,practical,and facile sensors is highly needed.This work presents a flexible and disposable paper-based NO_(2)sensor based on a reduced graphene oxide/chitosan(r GO/CS)composite.The synthesized r GO/CS composite can be easily flexed and deformed into various shapes,which are attributed to chitosan molecules that function as a dispersion and reduction agent and support material.In addition,this composite can be attached to paper owing to its adhesive property;hence it can be utilized in versatile applications in a disposable manner.By analyzing the conductive change of the r GO/CS composite when it reacts with NO_(2),we can detect nitrogen dioxide in a concentration range of 0–100 ppm with a detection limit of 1 ppm.Moreover,we performed NO_(2)detection in the exhaust gas released by automobiles using the r GO/CS composite for practical application.The results indicated that the r GO/CS composite has the potential to be used in feasible gas sensing as a facile and disposable sensor under various conditions. | Hyunjun Park Woong Kim Sang Won Lee Joohyung Park Gyudo Lee Dae Sung Yoon Wonseok Lee Jinsung Park | 2022 | Journal of Materials Science & Technology2022，，6： | 1 |
| 4 | Evaluation of Nitrogen Loads from Anthropogenic and Natural Sources by an integrated Biogeochemical Modeling Frame显示文摘This study proposed an integrated biogeochemical modeling of nitrogen load from anthropogenic and natural sources in Japan.Firstly,the nitrogen load(NL) from different sources such as crop,livestock,industrial plant,urban and rural resident was calculated by using datasets of fertilizer utilization,population distribution, land use map,and social census.Then,the nitrate leaching from soil layers in farmland,grassland and natural conditions was calculated by using a | Taikan Oki Tomoko Nitta Hyunjun Kim Shinta Seto Shinjiro Kanae | 2009 | 地学前缘2009，16，S1： | 0 |
