Stainless Steelmediated Quantitative Hydrogen Generation

Green Preparation Of Cellulose Nanocrystal And Its Application A green method was used to prepare cellulose nanocrystals cncs with no use of harsh chemicals or organic solvents this method was simple viaball millingcellulose with water followed by centrifugation the diameter and length of the cncs were 310 nm and 120400 nm separately with a aspect ratio of 2060 the yield was about 20 the thermal stability of the cncs was the same as Pdfpowder Metallurgy And Its Application Inthe Ii using a discmill a particle size of around 100 m was achieved iii pulverization byball millingin a stainless steel container with an inert solution produced a particle size of about 3 m iv the powders thus obtained were aligned in a magnetic field at 200kam and pressed at a Retsch News Events Solutions In Milling Sieving Powerful and safe the new planetary ball mill pm 400 the retsch planetary ball mills are characterized by excellent performance versatility safety and simple operation they are not only excellent tools for mixing and grinding solids down to the submicron range but are also frequently used for colloidal grinding and mechanical alloying
