Review on new heavy oil viscosity reduction technologies

IOP Conference Series: Earth and Environment, 2022
Lots of gum and asphaltene in heavy oil caused high viscosity, high density and poor fluidity, which makes it very difficult to exploit and transport heavy oil.

Energy Saving and Energy Generation Smart Window with Active Control and Antifreezing Functions

Advanced Science, 2022
Windows are the least energy efficient part of the buildings, as building accounts for 40% of global energy consumption. Traditional smart windows can only regulate solar transmission, while all the solar energy on the window is wasted.

Experimental Study on Breakthrough Separation for Hydrogen Recovery from Coke Oven Gas Using ZIF-8 Slurry

Energies, 2022
A large amount of COG (coke oven gas) is produced from coking plants every year, which contains 55–60% H2. In this work, the breakthrough separation of H2 from COG with ZIF-8/ethylene glycol-water slurry was studied.
