Effects of Biochar and Maize Roots on CO2 Emissions and Microbial Biomass C in Loess Soils

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Refractory substances such as biochar and labile substances such as dead fine and coarse roots play important roles in soil organic matter dynamics and have key ecological functions. However, interactions between these substances have only rarely been studied.

Comparative Evaluation of Structure–Processing–Property Relationships in Flax, Hemp, and Cattail Discontinuous fiber Thermoset Composites

Polymer Composites, EarlyView.
Needle punching reorients fibers from in‐plane direction toward z‐direction of the web, resulting in mechanical interlocking of fibers and reduction in the nonwoven mat thickness. ABSTRACT Replacement of glass fiber mats, utilized in large and complex composite parts in the transportation industry, with natural fiber mats requires knowledge of natural ...
