Jun 22, 2023 (Nanowerk News) Meeting the 1.5 °C goal of the Paris Agreement will require ambitious climate action this decade. Difficult questions remain as to how warming can be limited within technical realities while respecting the common but differentiated responsibilities and respective capabilities of nations on the way to...
Large-scale (4-inch) plasma etching technology for mass production of next-generation two-dimensional semiconductors
Jun 22, 2023 (Nanowerk News) A groundbreaking plasma etching technology has been developed that promises to form the bedrock for the industrial production of molybdenum disulfide (MoS2), a next-generation two-dimensional (2D) semiconductor. This large-scale (4-inch), highly uniform, and defect-free technology stands as an advancement of considerable significance. The joint research...
New 3D-printing method builds structures with two metals
Jun 22, 2023 (Nanowerk News) Taking a cue from the structural complexity of trees and bones, Washington State University engineers have created a way to 3D-print two types of steel in the same circular layer using two welding machines. The resulting bimetallic material proved 33% to 42% stronger than either...
Making the most of minuscule metal mandalas
Jun 22, 2023 (Nanowerk News) To unveil the previously elusive behavior and stability of complex metal compounds found in aqueous solutions called 'POMs', researchers at the University of Vienna have created a speciation atlas now published in Science Advances ("Speciation atlas of polyoxometalates in aqueous solutions"). This achievement has the...

Exoplanet may reveal secrets about the edge of habitability
Jun 21, 2023 (Nanowerk News) How close can a rocky planet be to a star, and still sustain water and life? A recently discovered exoplanet may be key to solving that mystery, providing important insights about conditions at the inner edge of a star’s habitable zone and why Earth and...
Directly imaging quantum states in two-dimensional materials
Jun 21, 2023 (Nanowerk News) When some semiconductors absorb light, excitons (or particle pairs made of an electron bound to an electron hole) can form. Two-dimensional crystals of tungsten disulfide (WS2) have unique exciton states that are not found in other materials. However, these states are short lived and can...
