As a result, suspended particles in the drops are transported to the edge of the droplet, and deposited in a circular stain. We have characterized the topologies of the deposit using skewness of the profile as a simple analytic method for quantifying the shapes: pillars produce positive, flat deposits have zero skew and ring stain have a negative skew.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786138838180\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786138838180","offer_id":40151808966749,"sku":"9786138838180","price":89.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/daa40a75-2249-4dac-9b7d-1f8464d3d2ff.jpg?v=1775195990","url":"https:\/\/shop.autorenwelt.de\/en\/products\/experimental-investigation-of-drying-droplets-containing-microparticle-von-yohana-msambwa","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
