Proton-exchange membrane water electrolysis is a promising technology for green hydrogen production, but its widespread commercialization is hindered by the high cost and scarcity of precious-metal-based catalysts for the oxygen evolution reaction (OER). Recent progress has been made in developing low-...

through visual interpretation of high-resolution (0.8–2 m) Gaofen satellite images before and after the earthquake, 167 landslides were delineated, 18 of which were inspected in the field
Ca(solid)+Cl2(gas)⇒CaCl2(solid)+heat All the metals except beryllium form oxide layers in air at room temperature that dulls the surface of the metal. Barium is so reactive that it is stored under oil. All of the metals except beryllium reduce water and dilute acids to hydrogen: Mg(...
Due to the high cost of commercial instruments (around £70k for a portable device) the oil and gas industry has been the most prolific user of gravimetry, where it is often used as a pre-drilling survey method to investigate subterranean geological features1,2. Gravimetry has also been ...
“We put up cash and the number is 175,” President Trump said. “She shouldn’t be complaining about the bonding company. The bonding company would be good for it because I put up the money. I have plenty of money to put up.” After the hearing, President Trump’s lawyer in the ...

Multiple lines of evidence indicate an active hydrogeological history of Mars and chemolithoautotrophy-suited environments within its Noachian terrains. As a result, one of the primary aims of upcoming missions to Mars is to search for signs of ancient l
