NIR spectroscopy can evaluate the crystallinity and the tensile and burst strengths of nanocellulosic films

The near infrared (NIR) spectroscopy presents it self as an interesting non-destructive test tool as it enables a fast, simple and reliable way for characterizing large samplings of biological materials in a short period of time. This work aimed to establish multivariate models to estimate the cryst...
