The pH dependent peroxidase activity of Fe3O4 NP results in generation of radical ·OH radical via the unique Fenton chemistry of iron. However, their pH dependent activity is restricted to acidic environment and dramatic loss in antibacterial activity is observed at near neutral pH. Here we describe a novel strategy to overcome the pH lacunae of citrate coated Fe3O4 NP by utilizing adenosine triphosphate disodium salt (ATP) as a synergistic agent to accelerate the radical ·OH radical production and restore its antibacterial activity over a wide range of pH. This synergistic combination (30 µg/mL Fe3O4 NP and 2.5 mM ATP) shows a high bactericidal activity against both gram positive (B. subtilis) and gram negative (E. coli) bacterial strains, in presence of H2O2, at neutral pH. The synergistic effect (Fe3O4 NP + ATP) is determined from the viability assessment and membrane damage studies and is further confirmed by comparing the concentration of generated radical ·OH radicals. Over all, this study illustrates ATP assisted and radical dotOH-mediated bactericidal activity of Fe3O4 nanozyme at near neutral pH.]]> Wed 27 Jul 2022 14:33:27 AEST ]]> Microporous carbon nitride (C₃N₅․̣₄) with tetrazine based molecular structure for efficient adsorption of CO₂ and water https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42500 Wed 24 Aug 2022 09:11:19 AEST ]]> Silica-based nanomaterials as drug delivery tools for skin cancer (melanoma) treatment https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39596 Wed 15 Jun 2022 12:47:16 AEST ]]> Emerging trends in porous materials for CO2 capture and conversion https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47191 2 in the atmosphere needs to be curbed with suitable measures including the reduction of CO2 emissions at stationary point sources such as power plants through carbon capture technologies and subsequent conversion of the captured CO2 into non-polluting clean fuels/chemicals using photo and/or electrocatalytic pathways. Porous materials have attracted much attention for carbon capture and in the recent past; they have witnessed significant advancements in their design and implementation for CO2 capture and conversion. In this context, the emerging trends in major porous adsorbents such as MOFs, zeolites, POPs, porous carbons, and mesoporous materials for CO2 capture and conversion are discussed. Their surface texture and chemistry, and the influence of various other features on their efficiency, selectivity, and recyclability for CO2 capture and conversion are explained and compared thoroughly. The scientific and technical advances on the material structure versus CO2 capture and conversion provide deep insights into designing effective porous materials. The review concludes with a summary, which compiles the key challenges in the field, current trends and critical challenges in the development of porous materials, and future research directions combined with possible solutions for realising the deployment of porous materials in CO2 capture and conversion.]]> Wed 14 Dec 2022 16:09:47 AEDT ]]> Egg-yolk core-shell mesoporous silica nanoparticles for high doxorubicin loading and delivery to prostate cancer cells https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51674 Wed 13 Sep 2023 13:23:44 AEST ]]> Borophene Embedded Cellulose Paper for Enhanced Photothermal Water Evaporation and Prompt Bacterial Killing https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50279 Wed 12 Jul 2023 16:38:07 AEST ]]> Folic acid functionalised mesoporous core-shell silica nanoparticles loaded with carboplatin for lung cancer therapy https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52447 Wed 11 Oct 2023 14:53:52 AEDT ]]> Mesoporous Carbon Nitrides as Emerging Materials: Nanoarchitectonics and Biosensing Applications https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53691 Wed 10 Jan 2024 10:34:44 AEDT ]]> Multifunctional applications of biochar beyond carbon storage https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45684 Wed 07 Feb 2024 16:37:32 AEDT ]]> Copper nanoparticles decorated N-doped mesoporous carbon with bimodal pores for selective gas separation and energy storage applications https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47353 Tue 30 Apr 2024 15:16:20 AEST ]]> Emerging Trends of Carbon-Based Quantum Dots: Nanoarchitectonics and Applications https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50377 Tue 08 Aug 2023 14:08:09 AEST ]]> Development and characterization of human fetal female reproductive tract organoids to understand Müllerian duct anomalies https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53981 Thu 25 Jan 2024 12:57:12 AEDT ]]> Milk derived highly ordered mesoporous carbon with CaF2 nanoclusters as an efficient electrode for supercapacitors https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46376 2 nanoclusters along the pore wall structure using dairy milk as a carbon and calcium source through nano-hard templating approach wherein mesoporous silica SBA-15 with different pore diameters are used as template. CaF2 is introduced during the removal process of silica template and can help to enhance the charge transfer. Nitrogen adsorption results reveal that the prepared materials exhibit high specific surface area with bimodal porous structures which act as a media for the rapid ion transports through the regular and interconnected micro- and mesoporous structure. The mesoporous carbon samples also exhibit hexagonally ordered pores with rod shaped morphology, which is similar to that of the template, confirming that the templating process is successful. Finally, the optimised electrode is highly stable and offers the capacitance of 182 F g-1 at 0.5 A g-1 with almost 100% retention rate even after 5000 cycles due to a strong intimate coupling generated by the CaF2 nanoclusters within the wall structure. The electrode performance of milk derived carbon samples is much better than that of activated carbon, multiwalled carbon nanotubes and the mesoporous carbons without CaF2.]]> Thu 17 Nov 2022 09:55:45 AEDT ]]> Circular economy adoption by SMEs in emerging markets: Towards a multilevel conceptual framework https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48414 Thu 16 Mar 2023 14:03:55 AEDT ]]> Triple Surfactant Assisted Synthesis of Novel Core-Shell Mesoporous Silica Nanoparticles with High Surface Area for Drug Delivery for Prostate Cancer https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48220 Sat 11 Mar 2023 12:36:58 AEDT ]]> Metal nitride-based nanostructures for electrochemical and photocatalytic hydrogen production https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45392 Mon 29 Jan 2024 18:36:10 AEDT ]]> Highly graphitized porous biocarbon nanosheets with tunable Micro-Meso interfaces and enhanced layer spacing for CO<inf>2</inf> capture and LIBs https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49141 Mon 29 Jan 2024 18:33:06 AEDT ]]> Mesoporous titanium carbonitride derived from mesoporous C3N5 for highly efficient hydrogen evolution reaction https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51886 Mon 29 Jan 2024 18:32:53 AEDT ]]> Recent Progress in Synthesis and Application of Biomass-Based Hybrid Electrodes for Rechargeable Batteries https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50301 Mon 29 Jan 2024 18:28:01 AEDT ]]> Material-based generation, storage, and utilisation of hydrogen https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52716 Mon 29 Jan 2024 18:23:04 AEDT ]]> Recent Advances in Carbon-Based Electrodes for Energy Storage and Conversion https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50891 Mon 29 Jan 2024 18:22:27 AEDT ]]> Highly enhanced photocatalytic hydrogen evolution activity of graphitic carbon nitride with 3D connected mesoporous structure https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39863 2/g).
