Material Characterization of Lignin‐Filled Polypropylene Composites

Journal of Applied Polymer Science, Volume 143, Issue 40, October 20, 2026.
Ground and spray‐dried lignin powders are compared as fillers for polypropylene composites. Differences in powder preparation methods are associated with differences in powder characteristics and composite behavior after melt compounding. Spray‐dried lignin produces smaller particles and fewer large agglomerates, while a 5 wt% lignin loading provides a

Thermal behaviour of hardwood and softwood composites

, 2014
In the present study, the thermongravimetric analysis (TGA) of laboratory hardwood and softwood particleboard was studied. The TGA showed that both hardwood and softwood have similar thermal behaviour at the same peak temperature.

Effects of Morphological Age and Indole-3-Butyric Acid Concentration on Rooting of Selected Robusta Coffee Varieties

Coffee and Cocoa Research Journal
In response to the outbreak of Coffee Wilt Disease (CWD) which wiped out almost 50% of Robusta coffee in Uganda, the National Coffee Research Institute (NaCORI) released 10 varieties (KR1-10) which are resistant to the disease. These varieties are being

Evaluation of the relationship between pilot hole dimensions and screw holding strength in softwood furniture elements

Maderas: Ciencia y Tecnología
The influence of pilot-hole geometry on screw holding strength in solid softwood furniture elements remains insufficiently understood, particularly when wood species, pilot-hole dimensions, and grain direction are considered simultaneously.
