The materials used were poly(methyl methacrylate) (PMMA), glass, and anatase. The interaction of the bubbles, once brought into contact, was monitored using high-speed video recording. Visual inspection indicated that denser particles were more easily displaced during the contact of the bubbles and therefore the PMMA particles provided a particle barrier more resistant to coalescence. The coalescence events yielded information on the surface properties of the bubble and the detachment of particles. The attached particles commonly dampen the oscillation of the coalesced bubbles through viscous drag and change in the surface properties (e.g., area-exclusion principle). The dampening of the oscillation generally leads to a reduced mass of particles detaching from the bubble surface. It was found that the different materials investigated did not offer clear evidence of the effect of particle detachment on the bubble surface properties in the present systems. On the other hand, the detachment of different particle materials seemed to be consistent with one another when comparing the attachment and detachment forces exerted on the particles based on their density, size, and hydrophobicity. It was concluded that particles of lower density are more effective in stabilizing interfaces, and thus particle density is an important parameter in the selection of materials for the handling of dispersions.]]> Wed 11 Apr 2018 13:00:50 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:4916 Wed 11 Apr 2018 11:54:47 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:4355 Wed 11 Apr 2018 09:42:12 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:43668 Tue 27 Sep 2022 15:14:53 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:55370 Tue 21 May 2024 13:35:53 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:35236 -3. The results show that no chemical reaction occurred between the AZ91 matrix and the activated carbon particles. The mechanical properties of the foam were evaluated under quasi-static compression loading conditions, and showed a consistent trend for the energy absorption of the fabricated AZ91-AC syntactic foams. The deformation mechanism of samples was a brittle fracture mode with the formation of shear bands during the fracture of all samples.]]> Tue 02 Jul 2019 15:14:51 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:539 Thu 25 Jul 2013 09:10:32 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:8042 Sat 24 Mar 2018 08:35:03 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:920 Sat 24 Mar 2018 08:29:41 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:18480 Sat 24 Mar 2018 07:59:48 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:19243 Sat 24 Mar 2018 07:54:57 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:6247 Sat 24 Mar 2018 07:48:39 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:282 Sat 24 Mar 2018 07:42:51 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:31108 3 and a porosity range of 0.79–0.93 for expanded perlite particle sizes between 3 and 4 mm, a compaction ratio range of 1–3.56, and a pure sodium silicate content range of 0.05–0.35 g/ml in dilution of water for binder.]]> Sat 24 Mar 2018 07:35:06 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:28321 Sat 24 Mar 2018 07:25:14 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:24752 −1 and 4000 Pa s, while the density remained close to the density of water.

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 ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:46950 2O₄@ZnCo₂O₄ (RNZC) ternary composite material is synthesized using a simple hydrothermal method. In this report, we demonstrate the effect of rGO concentration on the electrochemical behavior of the rGO/NiCo₂O₄@ZnCo₂O₄ composite materials. The specific capacity values of the ternary composite materials increase with rGO concentration up to 50 mg. Furthermore, on increasing the rGO concentration, the capacity value decreases. Among the prepared samples, the composite with 50 mg of rGO (RNZC3) exhibits a maximum specific capacity of 1197 C g^–1 at a current density of 1 A g^–1. We also demonstrate the design of a supercapacitor device with high specific energy density using RNZC3. The RNZC3//RNZC3 symmetric supercapacitor device exhibits a maximum energy density of 62 W h kg^–1. In the case of an asymmetric supercapacitor device, the applied potential range is extended beyond the water decomposition range. Enhancement of the potential window ensures to achieve a high energy density. The RNZC3//rGO asymmetric supercapacitor device reaches the highest energy density of 71 W h kg^–1 and the corresponding power density is 0.98 kW kg^–1.]]> Fri 09 Dec 2022 14:35:39 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:45728 A$49 900), RPAS thermal imaging surveys were cost-effective, detecting the highest number of koalas per dollar spent. Modelling also suggested that RPAS thermal imaging requires the lowest survey effort to detect koalas within the range of publicly available koala population densities (~0.006–18 koalas ha−1) and would provide long-term cost reductions across longitudinal monitoring programs. RPAS thermal imaging would also require the lowest average survey effort costs at a landscape scale (A$3.84 ha−1), providing a cost-effective tool across large spatial areas. Conclusions: Our analyses demonstrated drone thermal imaging technology as a cost-effective tool for conservation practitioners monitoring koala populations. Our analyses may also form the basis of decision-making tools to estimate survey effort or total program costs across any koala population density. Implications: Our novel approach offers a means to perform various economic comparisons of available survey techniques and guide investment decisions towards developing standardised koala monitoring approaches. Our results may assist stakeholders and policymakers to confidently invest in RPAS thermal imaging technology and achieve optimal conservation outcomes for koala populations, with standardised data collection delivered through evidence-based and cost-effective monitoring programs.]]> Fri 04 Nov 2022 09:52:04 AEDT ]]>
