Morphology Effect of Puffball Spores on Hemostasis: A Promising Solution for Hemostatic Challenges
Advanced Science, EarlyView.This work presents an innovative approach to address current challenges in hemostasis by drawing inspiration from the natural hemostatic material, Puffball spores (Bovistella sp.). Their unique hollow ball‐rod morphology and texture composition enable blood concentration and promote the release of procoagulant factors, while the nano‐protrusions on the

Fire and Materials, Volume 47, Issue 1, Page 28-50, January/February 2023., 2023 Summary The interactions of Calcium carbonate (e.g., eggshell powder) and Lignin with ammonium polyphosphate (APP) when used as fire retardants were investigated. Three mixing ratios ‐ 1:3, 1:1, and 3:1, were used with natural fibre reinforced composites containing a hemp mat and an epoxy matrix manufactured using a light resin transfer moulding (L‐RTM)
