Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Journal of Wood Chemistry and Technology, 2013 Abstract The sizes and shapes of wet ball-milled wood flour were investigated based on their average particle size, size distribution, their solution viscosity, and scanning electron microscopy images. The ball-milling conditions were combinations of rotational speed (150, 200, and 250 rpm) and milling time (1 to 16 h). The average diameter of the wood

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

IMPROVED INTERFACIAL BONDING OF PVC/WOOD-FLOUR COMPOSITES BY LIGNIN AMINE MODIFICATION
BioResources, 2011 Soda lignin was divided into two fractions with different molecular weights by methanol extraction. Lignin amine was synthesized from the low-molecular-weight lignin fraction via Mannich reaction and was used for interfacial modification of poly ...

Thermal, mechanical and morphological properties of polypropylene/clay/wood flour nanocomposites
eXPRESS Polymer Letters, 2008 Nanocomposites with polypropylene/clay/wood flour were prepared by melt compounding. Thermal, mechanical and morphological properties were characterized. The addition of clay, compatibilizer and wood flour considerably improved the thermal stability (i.e.

Rheology of Wood Flour Filled Poly(lactic acid)
Procedia Engineering, 2017 Abstract This work investigates the rheological properties of wood flour filled poly(lactic acid) at typical processing temperatures, i.e. 155°C, 165°C and 175°C, using a parallel plate rheometer run in oscillatory mode. Materials with three different filler loading levels (10, 20 and 30% wt.) are characterized together with the neat matrix ...

Cereal Chemistry, EarlyView.ABSTRACT Background and Objectives Sulfur and nitrogen affect wheat yield and the protein content and quality. Hard red spring wheat (Albany cultivar) grown under six different soil nitrate application levels (0, 60, 120, 180, 240, and 300 lbs/acre) and two sulfur levels (0 or 20 lbs/acre) was used.
