The rate of drug release from the nanoparticles is proportional to the increase in the solution pH and inversely proportional to the content of the loaded lovastatin. The drug release process is divided into two stages: a rapid stage over the first 10 hr, then the release becomes gradual and stable. The Korsmeyer-Peppas model is most suitable for the lovastatin release process from the alginate/chitosan/lovastatin nanoparticles in the first stage, and then the drug release complies with other models depending on solution pH in the slow release stage. In addition, the toxicity of alginate/chitosan/lovastatin (abbreviated ACL) nanoparticles was sufficiently low in mice in the acute toxicity test. The LD50 of the drug was higher than 5000 mg/kg, while in the subchronic toxicity test with treatments of 100 mg/kg and 300 mg/kg ACL nanoparticles, there were no abnormal signs, mortality, or toxicity in general to the function or structure of the crucial organs. The results show that the ACL nanoparticles are safe in mice and that these composite nanoparticles might be useful as a new drug carrier.]]> Tue 09 Nov 2021 15:27:06 AEDT ]]> Ordered Mesoporous Boron Carbon Nitrides with Tunable Mesopore Nanoarchitectonics for Energy Storage and CO2 Adsorption Properties https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54120 -1 at 0.5 A g-1 ), large specific capacity for sodium-ion battery (349 mAg h-1 at 50 mAh g-1 ), and excellent CO2 adsorption capacity (27.14 mmol g-1 at 30 bar).

The optimized material exhibits a high surface area of 2278m2 g−1 and a pore volume of 1.00 cm3 g−1. As high microporosity is beneficial for CO2 adsorption, the prepared materials are employed as adsorbents for the capture of CO2. The optimized sample displays excellent CO2 uptakes at 0 °C/0.15 bar (1.1–1.8 mmol g−1) and 0 °C/1 bar (4.3–6.1 mmol g−1). The high surface area of the materials allows for high CO2 uptakes at 0 °C/30 bar (17.3–22.0 mmol g−1). The microporosity of these high surface area carbons is further decorated with strontium carbonate nanoparticles. The adsorption capacity per unit surface area is increased significantly upon the incorporation of the nanoparticles, revealing the role of the nanoparticles on the enhancement of the CO2 adsorption capacity. A similar strategy could be extended for the fabrication of a series of microporous carbons derived from biomass for many applications including CO2 capture.]]> Fri 11 Nov 2022 19:13:04 AEDT ]]> Mixed copper/copper-oxide anchored mesoporous fullerene nanohybrids as superior electrocatalysts toward oxygen reduction reaction https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46128 Fri 11 Nov 2022 15:22:03 AEDT ]]> Fabrication of hybrid supercapacitor device based on NiCo₂O₄@ZnCo₂O₄ and the biomass-derived N-doped activated carbon with a honeycomb structure https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46101 2O4 materials with different morphologies including spherical, urchin, rod and granular are synthesized using different surfactants.

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.
