ASSESSMENT OF PINE BIOMASS DENSITY THROUGH MID-INFRARED SPECTROSCOPY AND MULTIVARIATE MODELING 

Via, Brian; Fasina, Oladiran; Pan, Hui (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 ...

Cellulose Reinforcement of Phenol Formaldehyde: Characterization and Chemometric Elucidation 

Atta-Obeng, Emmanuel; Via, Brian; Fasina, Oladiran; Auad, Maria; Jiang, Wei (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 ...

A comparison of geometry effect on tensile testing of wood strands 

Kohan, Neil; Via, Brian; Taylor, Steve (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 ...

Effect of microcrystalline cellulose, species, and particle size on mechanical and physical properties of particleboard 

Atta-Obeng, Emmanuel; Via, Brian; Fasina, Oladiran (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 

Neimsuwan, Trairat; Wang, Siqun; Via, Brian (2013-04-09)
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. ...

Fabrication and characterization of a triple functionalization of graphene oxide with Fe3O4, folic acid and doxorubicin as dual-targeted drug nanocarrier 

Wang, Zonghua; Zhou, Chengfeng; Xia, Jianfei; Via, Brian; Xia, Yanzhi; Zhang, Feifei; Li, Yanhui; Xia, Linhua (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 ...

IMPREGNATION OF BIO-OIL FROM SMALL DIAMETER PINE INTO WOOD FOR MOISTURE RESISTANCE 

Robinson, T.J.; Via, Brian; Fasina, Oladiran; Adhikari, Sushil; Carter, Emily (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 ...

Modeling for proximate analysis and heating value of torrefied biomass with vibration spectroscopy 

Via, Brian; Adhikari, Sushil; Taylor, Steve (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, ...

Prediction of strand feedstock mechanical properties with near infrared spectroscopy. 

Kohan, Neil; Via, Brian; Taylor, Steve (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 ...

The Response of Visible/Near Infrared Absorbance to Wood-Staining Fungi 

Via, Brian; Eckhardt, Lori; So, C; Shupe, Todd; Groom, Les; Stine, Mike (2013-04-09)
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 ...
