Interfacially Engineered Alginate/Hydroxyapatite Biocomposites With High Strength and Toughness
Polymer Composites, EarlyView.Pre‐crosslinking alginate with Ca2+ prior to hydroxyapatite (HAP) formation reduces residual Ca2+ bridging and promotes stronger carboxylate‐hydroxyapatite interfacial interactions, yielding composites with markedly higher strength, stiffness, and toughness than those prepared by the opposite sequence.

Roll‐to‐Roll Processing of Biodegradable Multilayer Barrier Packaging Structures
Packaging Technology and Science, EarlyView.This work demonstrates that novel packaging materials built using biobased and biodegradable materials can be produced in pilot‐scale and converted into functional barrier packaging. The proposed structures are anticipated to make a strong impact in use‐cases where the risk of environmental littering is elevated, such as snacks and take away meals ...

Implications of Restrictions on Imports of Canadian Softwood Lumber to the Southern Softwood Lumber Industry [PDF]
Review of Regional Studies, 1987 A number of policy options for the U.S. softwood industry are under consideration and there are indications that some form of restriction of the Canadian imports is imminent. The purpose of this paper is to evaluate the effects of trade restrictions and domestic subsidy on the southern softwood lumber industry.

A review of the configuration of bordered pits to stimulate the fluid flow
Maderas: Ciencia y Tecnología, 2014 As the bordered pits have generally been thought to have an influence on the refractory nature of softwoods, structural behaviour of this conducting pathways is discussed according to the published literature.
