Chemometric modeling of thermogravimetric data for the compositional analysis of forest biomass 

Acquah, Gifty E.; Via, Brian K.; Fasina, Oladiran O.; Adhikari, Sushil; Billor, Nedret; Eckhardt, Lori G.; 0000-0003-4269-0903; 0000-0003-2676-7376; 0000-0003-4214-163X; 0000-0002-3270-8199 (2020-04-01)
The objective of this study was to investigated the use of chemometric modeling of thermogravimetric (TG) data as an alternative approach to estimate the chemical and proximate (i.e. volatile matter, fixed carbon and ash ...

High Throughput Screening of Elite Loblolly Pine Families for Chemical and Bioenergy Traits with Near Infrared Spectroscopy 

Acquah, Gifty E.; Via, Brian K.; Gallagher, Tom; Billor, Nedret; Fasina, Oladiran O.; Eckhardt, Lori G.; 0000-0003-4269-0903; 0000-0003-2676-7376; 0000-0003-4214-163X; 0000-0002-3270-8199 (2020-04-01)
Pinus taeda L. (loblolly pine) dominates 13.4 million ha of US southeastern forests and contributes over $30 billion to the economy of the region. The species will also form an important component of the renewable energy ...

Identifying Plant Part Composition of Forest Logging Residue Using Infrared Spectral Data and Linear Discriminant Analysis 

Acquah, Gifty E.; Via, Brian K.; Billor, Nedret; Fasina, Oladiran O.; Eckhardt, Lori G.; 0000-0003-4269-0903 (2020-05-26)
As new markets, technologies and economies evolve in the low carbon bioeconomy, forest logging residue, a largely untapped renewable resource will play a vital role. The feedstock can however be variable depending on plant ...

Near Infrared Spectroscopy Calibration for Wood Chemistry: Which Chemometric Technique Is Best for Prediction and Interpretation? 

Via, Brian K.; Zhou, Chengfeng; Acquah, Gifty E.; Jiang, Wei; Eckhardt, Lori G. (2019-08-02)
This paper addresses the precision in factor loadings during partial least squares (PLS) and principal components regression (PCR) of wood chemistry content from near infrared reflectance (NIR) spectra. The precision of ...

Rapid Quantitative Analysis of Forest Biomass Using Fourier Transform Infrared Spectroscopy and Partial Least Squares Regression 

Acquah, Gifty E.; Via, Brian K.; Fasina, Oladiran O.; Eckhardt, Lori G.; 0000-0003-4269-0903; 0000-0003-2676-7376; 0000-0002-3270-8199 (2020-04-02)
Fourier transform infrared reflectance (FTIR) spectroscopy has been used to predict properties of forest logging residue, a very heterogeneous feedstock material. Properties studied included the chemical composition, thermal ...

Screening Pinus taeda (loblolly pine) families for physical and mechanical properties using vibrational spectroscopy 

Acquah, Gifty E.; Via, Brian K.; Eckhardt, Lori G.; 0000-0003-4269-0903 (2020-05-26)
In a bid to control the loblolly pine decline complex, stakeholders are using the selection and deployment of genetically superior families that are disease tolerant. It is vital that we do not compromise other important ...
