Monitoring of Powder Homogeneity During Double-Cone Blending
A challenge central to the Powder Metallurgy (PM) process is achieving consistent and uniform products. A crucial step in reaching this goal, is ensuring powder blending sufficiently homogenizes a...
Thermodynamics of Aerogel-Treated Nonwoven Fabrics at Subzero Temperatures
Nonwoven fabrics and aerogel have complementary properties required for good thermal insulation. In this work, the polyester/polyethylene nonwoven thermal wraps treated with amorphous silica aerogel...
The Effective Temperature at Which Fingertips Sense Thermal Effusivity and the Bias of Measurements
Thermoreceptors in the fingertips sense the temperature drop upon contact with an object and in that way its thermal effusivity. But, at which effective object temperature? That is the question...
