Application of ATR-FTIR Spectroscopy to Compare the Cell Materials of Wood Decay Fungi with Wood Mould Fungi
Gupta, Barun Shankar; Jelle, Bjørn Petter; Gao, Tao (Journal article; Peer reviewed, 2015)Wood fungi create vast damage among standing trees and all types of wood materials. The objectives of this study are to (a) characterize the cell materials of two major wood decay fungi (Basidiomycota), namely, Trametes ... -
In Vitro Cell Composition Identification of Wood Decay Fungi by Fourier Transform Infrared Spectroscopy
Gupta, Barun Shankar; Jelle, Bjørn Petter; Gao, Tao (Peer reviewed; Journal article, 2022)Decay pathogens follow dissimilar metabolic mechanisms to cause irreversible damage to woody tissues. The objective of this study is to perform inter- and intra-species microbial cell structural comparison using attenuated ... -
Non-Destructive Surface Characterization of Wood Façade Materials and Wood Fungi by Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy
Gupta, Barun Shankar (Doctoral theses at NTNU;2016:299, Doctoral thesis, 2016)Wood material is the dead xylem part of a tree that is being used for building construction, furniture, decorative items etc. Building façade is the outer envelope of a building. Wood façade materials are exposed against ... -
Studies of Wooden Cladding Materials Degradation by Spectroscopy
Gupta, Barun Shankar; Jelle, Bjørn Petter; Hovde, Per Jostein; Rüther, Petra (Journal article; Peer reviewed, 2011)Claddings or facades are the outer part of building envelopes. In this study, wooden claddings are exposed to natural and accelerated weathering. The natural climate exposure was performed at a field test site located in ... -
Wood coating failures against natural and accelerated climates
Gupta, Barun Shankar; Jelle, Bjørn Petter; Hovde, Per Jostein; Gao, Tao (Journal article; Peer reviewed, 2015)Monitoring, assessment and prediction of service life of materials are a serious challenge for the building and construction sector. According to ISO 15686 (2008), laboratory testing must be performed alongside field testing ... -
Wood Facade Materials Ageing Analysis by FTIR Spectroscopy
Gupta, Barun Shankar; Jelle, Bjørn Petter; Gao, Tao (Journal article; Peer reviewed, 2015)Attenuated total reflection Fourier transform infrared spectroscopy is used in this study to quantify wood degradation. Nine different types of wood materials were studied. All types of wood were exposed in an Atlas solar ...
