Supermassive Black Holes Control Star Formation Large Galaxies
2018/1/10
Young galaxies blaze with bright new stars forming at a rapid rate, but star formation eventually shuts down as a galaxy evolves. A new study, published January 1, 2018, in Nature, shows that the mass...

Researchers Novel Microreactor Methane Hydrate An Icy Prison Greenhouse Gas
2017/9/5
Researchers at the NYU Tandon School of Engineering are using a novel means of studying how methane and water form methane hydrate that allows them to examine discrete steps in the process faster and ...
Mathematical modeling of heat transfer in counter-current multiphase flow found in gas-drilling systems with formation fluid influx
Gas-drilling Temperature Prediction Influx Joule–Thomson Cuttings
2018/4/2
The performance of gas-drilling (drilling oil and gas wells with air, nitrogen, or natural gas) is very unpredictable in many areas due to lack of proper design of drilling parameters because of limit...
