Embedded Direct Ink Writing of Thermoset and Elastomeric Polymers via Frontal Polymerization
Advanced Functional Materials, EarlyView.Embedded frontal polymerization direct ink writing (FP‐DIW) combines frontal ring‐opening metathesis polymerization with embedded 3D printing to decouple deposition from curing. A yield‐stress support bath stabilizes low‐viscosity inks, while on‐demand thermal initiation enables controlled front propagation. This approach expands the accessible feature

Baseball Volume, Weight and Pitching Distance: Their Effects on “Little-Leaguer” Pitching Accuracy
, 1978 Three levels of baseball volume (21.2, 22.2, and 23.2 cm circumference) and three levels of baseball weight (71, 113.5, and 156 gm) were evaluated at three pitching distances (11.0, 13.7, and 16.5 m) to determine how these parameters affect “Little ...
