However, after 7 years in the garden, owing to natural degradation, weathering, or abrasion, microplastics are released. We categorize the plastic fragments into different groups, 5 mm–0.75 mm, 0.75 mm–100 μm, and 100–0.8 μm, using filters such as kitchenware, meaning we can collect microplastics in our gardens by ourselves. We then characterized the plastics using Raman image mapping and a logic-based algorithm to increase the signal-to-noise ratio and the image certainty. This is because the signal- to-noise ratio from a single Raman spectrum, or even from an individual peak, is significantly less than that from a spectrum matrix of Raman mapping (such as 1 vs. 50 × 50) that contains 2,500 spectra, from the statistical point of view. From the 10 g soil we sampled, we could detect the microplastics, including large (5 mm–100 μm) fragments and small (<100 μm) ones, suggesting the degradation fate of plastics in the gardens. Overall, these results warn us that we must be careful when we do gardening, including selection of plastic items for gardens.]]> Tue 26 Jul 2022 14:21:50 AEST ]]> Capture and characterisation of microplastics printed on paper via laser printer's toners https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46296 Tue 15 Nov 2022 09:18:54 AEDT ]]> Applying Raman imaging to capture and identify microplastics and nanoplastics in the garden https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47050 Tue 13 Dec 2022 14:58:04 AEDT ]]> Characterising microplastics in shower wastewater with Raman imaging https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47038 Tue 13 Dec 2022 14:22:22 AEDT ]]> Raman imaging of microplastics and nanoplastics generated by cutting PVC pipe https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47034 Tue 13 Dec 2022 14:08:24 AEDT ]]> Assessment of microplastics and nanoplastics released from a chopping board using Raman imaging in combination with three algorithms https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46997 Tue 13 Dec 2022 10:26:36 AEDT ]]> Collecting microplastics in gardens: case study (ii) from ropes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45549 Tue 01 Nov 2022 10:56:08 AEDT ]]> Online remote monitoring of explosives by optical fibres https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:25316 Sat 24 Mar 2018 07:30:22 AEDT ]]> SERS and NMR studies of typical aggregation-induced emission molecules https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27580 Sat 24 Mar 2018 07:23:43 AEDT ]]> An optical fibre sensor for remotely detecting water traces in organic solvents https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:23836 Sat 24 Mar 2018 07:12:10 AEDT ]]> Vortex fluidic induced mass transfer across immiscible phases https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48184 Sat 11 Mar 2023 12:23:41 AEDT ]]> Konjac glucomannan/polyvinyl alcohol nanofibers with enhanced skin healing properties by improving fibrinogen adsorption https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40725 Mon 18 Jul 2022 11:41:14 AEST ]]> Microplastics generated when opening plastic packaging https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40151 5 mm) plastic residues. We have found that microplastics can be generated by simple tasks in our daily lives such as by scissoring with scissors, tearing with hands, cutting with knives or twisting manually, to open plastics containers/bags/tapes/caps. These processes can generate about 0.46–250 microplastic/cm. This amount is dependent on the conditions such as stiffness, thickness, anisotropy, the density of plastic materials and the size of microplastics. This finding sends an important warning, that we must be careful when opening plastic packaging, if we are concerned about microplastics and care about reducing microplastics contamination.]]> Fri 22 Jul 2022 13:55:19 AEST ]]> Strain induced variation of PFOS adsorption on pristine and defected phosphorene: A DFT study https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40621 Fri 15 Jul 2022 13:34:13 AEST ]]> Raman imaging for the identification of Teflon microplastics and nanoplastics released from non-stick cookware. https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47291 Fri 13 Jan 2023 10:38:37 AEDT ]]> Fire releases micro- and nanoplastics: Raman imaging on burned disposable gloves https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47292 Fri 13 Jan 2023 10:38:34 AEDT ]]>
