What is fumed silica

Since the German Degussa Company successfully developed the production technology of gaseous phase SiO2 in 1941, the total annual production of gaseous phase SiO2 in the world has exceeded 150000 tons in 2007, and the production technology is highly concentrated. The global market is mainly controlled by a few companies such as German Degussa, Wacker, U.S. Cabot, and Japan Tokuyama, and the technology is also tightly controlled. A basic model for developing gaseous phase SiO2 globally is the clo

What Powder is Used for Metal 3D Printing

What Powder is Used for Metal 3D Printing? Flowability: A major characteristic for metal powder is the capacity to pass through the 3D printer. Materials that are more flowable can be controlled with greater ease and create more consistent products and layers. Furthermore they are less likely to make products with irregular layers. The better flowability of powder implies that it is easier to produce a metal 3D-printed product. Steel 316L powder Stainless The powder of stainless steel 316L h

Similarly, atomically thin layered Molybdenum Disulfide/graphene/WSe2 (p–g–n) vdWHs were developed by Long et al. In this view, graphene was sandwiched within the p–n junction to broaden the spectral absorption range and photodetection sensitivity. A side view of Molybdenum Disulfide/graphene/WSe2 vdWHs, a schematic for the broadband photodetection and the wavelength-dependent photoresponsivity and detectivity (D) of the Molybdenum Disulfide/graphene/WSe2-based broadband photodetector over the 4
