Experimental discovery of a new critical point in water

Researchers at Stockholm University have found a new critical point in supercooled water at around -63 °C and 1000 atmosphere. This discovery explains the unusual properties of water, such as its density and viscosity responding to pressure and temperature changes in ways that are opposite to other liquids.

Researchers reveal interfacial confinement on open space of oxide-oxide catalysts

A study by researchers from Dalian Institute of Chemical Physics reveals the interface confinement effect on open space in In2O3-TiO2 catalyst, leading to enhanced activity and stability. The formed InOx nanolayers show distinct chemistry and can be confined on various oxide surfaces.

Researchers determine active sites of Cu-ZnO catalysts for water gas shift and CO hydrogenation reactions

The study found that Cu-ZnO-Al2O3 catalysts have two active sites: CuCu(100) hydroxylated ZnO interface for water gas shift reactions and Cu(611) Zn alloy for CO hydrogenation to methanol. The researchers used in situ characterization technology and theoretical calculation to determine the active site structures.
