Acetone--Analysis; Air quality monitoring stations
Zinc oxide (ZnO) based gas sensors with sliver ion exchanged ZSM-5 (Ag+ZSM-5) zeolite overlayer were created and tested for detection of acetone vapor in air. The ZnO and Ag+ZSM-5 films were deposisted on 400µm by 400µm platinum interdigitated...
Ischemic heart disease is the leading cause of mortality and morbidity in Western societies. Thus, understanding the molecular mechanisms to reduce myocardial ischemia and limit infarction size are of great importance. Ample evidence has shown that...
Reperfusion of the ischemic lung causes pulmonary arteriolar vasoconstriction and reduces alveolar perfusion. Lung ischemia-reperfusion (IR) injury leads to platelet and leukocyte activation which could contribute to decreased alveolar perfusion...
Cerium dioxide or ceria, CeO2, has been widely used in industry as catalyst for automotive exhaust controls, chemical mechanical polishing (CMP) slurries, and high temperature fuel cells because of its unique metal oxide properties. This well-known...
As more attention is focused toward carbon dioxide emissions into the environment, conversion of CO2 to useful chemicals can utilize the extra carbon dioxide captured from power plant stack gas, instead of sequestration. The mainstream method of...
Dielectrophoresis (DEP) is an electrokinetic force capable of attracting or repelling neutrally charged particles due to a non-uniform electric field [1, 2]. Positive dielectrophoresis attracts particles in the region of the highest electric field...
III-nitrides (InN, GaN, AlN) are some of the most promising materials for making blue light emitting diodes (LED), blue laser diodes (LD) and high power, high temperature field effect transistors (FET). Current techniques produce GaN films with...
