Prediction of strand feedstock mechanical properties with near infrared spectroscopy.
(2013-04-04)
Wood strands either prepared in the laboratory or from a manufacturing plant were assessed for their ultimate tensile strength, tensile MOE, bending strength, and bending stiffness, and then near infrared spectroscopy was ...
Cellulose Reinforcement of Phenol Formaldehyde: Characterization and Chemometric Elucidation
(2013-04-05)
Micro sized crystalline cellulose was uniformly dispersed at loadings of 0, 3, 6, and 10% (by weight) in phenol formaldehyde (PF) and tested for thermal properties and shear strength. The application of cellulose into the ...
Fabrication and characterization of a triple functionalization of graphene oxide with Fe3O4, folic acid and doxorubicin as dual-targeted drug nanocarrier
(2013-04-04)
A novel triple functionalized drug delivery system was synthesized by encapsulation of superparamagnetic graphene oxide (GO) and doxorubicin (DOX) with folic acid (FA) conjugated chitosan (CHI). The carrier exhibited a ...
Effect of microcrystalline cellulose, species, and particle size on mechanical and physical properties of particleboard
(2013-04-05)
Particleboards made from both sweetgum (Liquidambar styraciflua) and southern pine (Pinus spp.) were made at a small and large particle size and at 0 and 10% microcrystalline cellulose loading. Modulus of rupture, modulus ...
Effect Of Processing Parameters, Resin, and wax Loading On Water Vapor Sorption of Wood Strands
(2013-04-10)
The outdoor use of oriented strandboard (OSB) is undesirable if exposed to atmospheric vapor or rain; however, increasing resin and wax content can mitigate adverse sorption behavior of panels under such negative conditions. ...
A comparison of geometry effect on tensile testing of wood strands
(2013-04-05)
There is currently no ASTM standard for testing the tensile mechanical properties of strands used in wood-strand–based
composites. In this study we compared the ultimate tensile strength (UTS) parallel to grain and tensile ...
IMPREGNATION OF BIO-OIL FROM SMALL DIAMETER PINE INTO WOOD FOR MOISTURE RESISTANCE
(2013-04-04)
Wood pyrolysis oil consists of hundreds of complex compounds, many of which are phenolic-based and exhibit hydrophobic properties. Southern yellow pine was impregnated with a pyrolysis oil-based penetrant using both a high ...
ASSESSMENT OF PINE BIOMASS DENSITY THROUGH MID-INFRARED SPECTROSCOPY AND MULTIVARIATE MODELING
(2013-04-04)
The assessment of wood biomass density through multivariate modeling of mid-infrared spectra can be useful for interpreting the relationship between feedstock density and functional groups. This study looked at predicting ...
The Response of Visible/Near Infrared Absorbance to Wood-Staining Fungi
(2013-04-10)
The influence of blue-stain fungi [Ophiostoma minus (Hedgcock) H. and P. Sydow and Leptographium serpens (Goid.) Siemaszko] on absorbance at the visible and near infrared wavelengths was investigated. Forty trees were ...
Modeling for proximate analysis and heating value of torrefied biomass with vibration spectroscopy
(2013-04-11)
The goal of this study was to characterize the changes in biomass with torrefaction for near infrared
reflectance (NIR) and attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy
for sweetgum, ...
