Jun 22, 2023 (Nanowerk News) Researchers have demonstrated significant improvements for chip-based sensing devices used to detect or analyze substances. The achievements lay the groundwork for highly sensitive portable integrated optofluidic sensing devices that could be used to perform various types of medical tests simultaneously even if they involve completely...
Spectroscopic micro-ellipsometer unveils atomic-level thickness measurements of 2D materials
Jun 22, 2023 (Nanowerk News) Two-dimensional (2D) material flakes consist of single to few atomic layers, granting them extraordinary quantum properties, which are not observed in everyday materials. As a result, these materials hold immense potential for both industrial applications and advanced research. Traditionally, ellipsometry has been a widely adopted...
Breakthrough innovation could solve temperature issues for source-gated transistors and lead to low-cost, flexible displays
Jun 22, 2023 (Nanowerk News) Low-cost, flexible displays that use very little energy could be a step closer, thanks to an innovation from the University of Surrey that solves a problem that has plagued source-gated transistors (SGT). SGTs are not widely used because current designs have a problem with how...
Will engineered carbon removal solve the climate crisis?
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...
