📢 Excited to share our recent study! Our study delves into the potential of Fourier Transform Infrared Photoacoustic Spectroscopy (FTIR-PAS) for predicting macro- and micro-nutrients in various manures and digestates. We introduced an error tolerance-based interval method to assess prediction accuracy for nitrogen and phosphorus, aiming to balance accuracy and practicality. By calculating the probability of prediction within allowed limits, we gained insights into the applicability of FTIR-PAS in practical settings. Moreover, our study addresses the limitations of existing evaluation techniques used for spectroscopy (R^2, RMSE, RPD), highlighting how these criteria alone may not suffice to assess test accuracy comprehensively. Recognizing the practical need and tolerable error in measurements could significantly enhance the applicability of spectroscopy in real-world scenarios.

🔍 Explore the recently published article "Bioimpedance Measurement of Avocado Fruit Using Magnetic Induction Spectroscopy." 📝 Authored by: Michael D. O'Toole; Marcin Glowacz; Anthony Peyton In this article, we explore the bioimpedance spectra of avocado fruit. Bioimpedance has been found to correlate with ripeness in avocado fruit over a frequency range termed the β -dispersion where cell polarization effects are significant. Our contribution is to use magnetic induction spectroscopy to measure conductivity across this range, an entirely noncontact method that uses eddy currents induced in the fruit flesh by magnetic fields rather than penetrative or surface electrodes as in previous work. 🔗 Continue reading on IEEE Xplore: https://loom.ly/F7y8kVg #Bioimpedance #agriculture #AgriFoodElectronics #AgTech #PrecisionAgriculture #IEEE #IEEEXplore #TAFE #Spectroscopy

Anne Steensma, me, and an awesome group of collaborators just put out a preprint where we use a combination of new measurements, metabolic modeling, and statistical analysis to conclusively show that the extremophilic red alga Cyanidioschyzon merolae has an operational Carbon Concentrating Mechanism (CCM) and explore mechanisms that may explain how its CCM works. This little alga lives at high temperatures and low pH (~pH 1.5) and doesn't have the structures the well-characterized microalgal CCM models do, so how is it accomplishing this?

Thalium-accumulating plants and their potential for use in the remediation of mine waste is the focus of a new research paper produced by SMI’s Environmental Geochemistry Group in collaboration with the Australian Synchrotron, University of Adelaide, and Wageningen University & Research. “Successful and sustainable rehabilitation and closure of mines requires deep understanding of the release, mobility, and uptake of metals by plants. Our focus is to contribute to the Metallomics (the study of metals in – biological – systems) of plant-substrate systems,” wrote the Environmental Geochemistry research group. “This latest publication is a good example of such an investigation. Thallium is a metal of high economic value, and at the same time is more toxic than arsenic and cadmium. We analysed the speciation and distribution of thallium in 25 edible cultivar of Brassica cultivars. Our studies greatly benefit from cutting edge synchrotron techniques used for metal speciation and mapping special distribution of metals in plants. We found that these edible crops can accumulate high levels of thallium. As such, these species can be used for remediation (phytoextraction), and as models to understand the toxicity of thallium in the environment.” Authors for the paper, which was published in Environmental Science & Technology, include Dr Amelia Corzo Remigio, Dr Hugh Harris, Clinton Kidman, Dr Philip Nti Nkrumah, Dr Lachlan Casey, Dr David Paterson, Dr Mansour Edraki and Dr Antony van der Ent.
