Journal Article
Popescu, C., Jones, D., Kržišnik, D., & Humar, M. (2020). Determination of the effectiveness of a combined thermal/chemical wood modification by the use of FT–IR spectroscopy and chemometric methods. Journal of Molecular Structure, 1200, Article 12713

In this study, the combined effects of chemical (with tricine and bicine) and thermal treatments were investigated. The modifications which appeared in the wood structure were evaluated by infrared spectroscopy and chemometric methods (principal comp...

Quantification of chemical changes taking place in spruce wood structure following long period thermal treatment (2019)
Presentation / Conference Contribution
Popescu, C., Ridley-Ellis, D., & Popescu, M. (2019, August). Quantification of chemical changes taking place in spruce wood structure following long period thermal treatment. Paper presented at 2DCOS-10, The 10th International Symposium on Two-dimensional

Wood is a natural composite polymer containing different amounts of cellulose, lignin and hemicelluloses and some other low molecular compounds (i.e. extractives). Due to its structure wood is susceptible to degradation in the surrounding environment...

Potential for estimating the age of instruments by characterisation of wood properties via acoustics. (2014)
Presentation / Conference Contribution
Ridley-Ellis, D., & Popescu, C. (2014, September). Potential for estimating the age of instruments by characterisation of wood properties via acoustics. Presented at WoodMusiCK (FP1302) conference ‘multidisciplinary approach to wooden musical instrument

The performance of musical instruments is sensitive to several wood properties that are affected by aging. These wood properties also change with temperature and humidity in ways that interact with (and change as a result of) aging processes. This of...

Stiffness changes during low temperature thermal treatment of Scots pine, assessed by acoustic NDT (2014)
Presentation / Conference Contribution
Ridley-Ellis, D., Popescu, C., Keating, B. A., Popescu, M., & Hill, C. A. S. (2014). Stiffness changes during low temperature thermal treatment of Scots pine, assessed by acoustic NDT. In L. Nunes, D. Jones, C. A. S. Hill, & H. Militz (Eds.), Proceedings

The change, over time, in density, longitudinal modulus of elasticity, shear modulus and chemical structure of Scots pine (Pinus sylvestris) under thermal treatment (110, 120 and 140 C) was evaluated. The determinations of the specific changes were c... Read More about Stiffness changes during low temperature thermal treatment of Scots pine, assessed by acoustic NDT.
