The "zero result" of Michelson Morley's experiment was not enough to deny the existence a fifth element---ether, as conceived by Aristotle. Hubble's explanation Doppler effect systematic cosmic red shift incomplete and needed be introduced into ether.The physical significance universal gravitation constant reveals possibility ether. After much thought logical reasoning, there is good reason thi...
hydrogen was produced by steam reforming of dimethyl ether (dme) using a physical mixture of commercial hzsm-5 zeolite (for dme hydrolyzing) and cu/zno/al2o3 (for methanol steam reforming) as a catalyst in a fixed bed reactor. the experiments were performed at atmospheric pressure and in a temperature range from 270 to 310 °c. the effects of feed temperature and gas hourly space velocity (ghsv)...
we found that dibenzo-18-crown-6 (db18c6) can be used as an ionophore to make a tin (ii)-ionselectivemembrane electrode. the electrode exhibits a near nernstian response for sn2+ ions over aconcentration range from 1.0× 10-6 – 1.0× 10-2 m with a slope of 27.5 ± 0.6 mv per concentration decadein an acidic solution (ph=1). the limit of detection was 8.0× 10-7 m. it has a response time of < 20s an...
methyl tert-butyl ether (mtbe), a gasoline octane enhancer, was introduced as a substitute for lead tetraethyl over 30 years ago. widespread use of mtbe in gasoline, has introduced mtbe into the environment compartments, mostly into the under ground and surface water and water as a second most frequently detected contaminant. in this study, we have isolated pure cultures from bacterial consorti...
The paper is an introduction into General Ether Theory (GET). We start with few assumptions about an universal " ether " in a New-tonian space-time which fulfils
