The prepared MCPI-PNs consisting of six groups (n=36), viz., vehicle treated control (group 1), alone MCP I @ 10 mg/animal/day (group 2), 46.03 nm sized blank mPEG-PLA nanomicelles @ 0.3 mL/animal/day (group 3), 100 nm sized MCPI-PNs (1.5, 3.0 and 4.5 µg/animal/day) (group 4), 129 nm sized MCPI-PNs (4.5, 9.0 and 13.5 µg/animal/day) (group 5) and 166 nm sized MCPI-PNs (13.5, 27.0 and 45.0 µg/animal/day) (group 6) were orally treated for a period of 30 days in albino male rats. Animals of groups 2, 4, 5 and 6 showed significantly altered sperm parameters. However, the sperm concentration maximally dropped in group 2 and 4 (low dose and mid dose), respectively, indicating the range of oligozoospermia to severe oligozoospermia in these groups. The fertility declined to zero percent in groups 2 and 4 (low dose), whereas all animals were 100% fertile in rest of groups. Histopathological studies of testes exhibited sloughing and eruption of germ cells with inhibition of spermatogenesis in groups 2 and 4, whilst some conspicuous alterations in spermatogenesis was observed in groups 5 and 6 when compared to groups 1 and 3. Based on the above observations, the group 4 (100 nm sized MCPI-PNs) at low dose regimen (1.5 µg/animal/day) exhibited maximum antifertility effects in male albino rats.</em>https://www.ijnnonline.net/article_715064_73040ccd2aaca75933c5afc9c0122db3.pdfIranian Nanotechnology SocietyInternational Journal of Nanoscience and Nanotechnology1735-700420220240501Development of a Marking Composition Based on Nanoaluminum and Iron Ore Concentrate for Mixed Explosives and Their Subsequent Identification9110271506610.22034/ijnn.2024.1988651.2328ENDaurenBaiseitovDepartment of chemistry, Abai Kazakh National Pedagogical University, Almaty, 050000, Kazakhstan0000-0002-6913-1549AigerimAkhinzhanovaFaculty of Chemistry and Chemical Technology, Al-Farabi Kazakh National University, 050040, Almaty, Kazakhstan0000-0003-3675-7526LarissaSassykovaFaculty of Chemistry and Chemical Technology, Al-Farabi Kazakh National University, 050040, Almaty, Kazakhstan0000-0003-4721-9758IngaAvdonkinaCommunal State Institution Lyceum No9 named after Vladimir Savva, Zhambyl region, 080515, Kazakhstan0000-0003-1058-206XMaratTulepovFaculty of Chemistry and Chemical Technology, Al-Farabi Kazakh National University, 050040, Almaty, Kazakhstan0000-0002-6449-9571IndiraRassulovaFaculty of Chemistry and Chemical Technology, Al-Farabi Kazakh National University, 050040, Almaty, Kazakhstan0009-0006-3022-2108Journal Article20230129<em> In this article, an experimental study of the methods for forming a marking composition based on nanoaluminum and iron ore concentrate for use as marking additives in mixed explosives was considered. The prepared marking composition consists of nanoaluminium - 95%, iron ore concentrate - 5%, and according to X-ray spectral analysis the intense peaks of aluminum (97.62%), iron (0.89%), calcium (0.64%), manganese (0.05%), chromium (0.009%), titanium (0.01%), sulfur (0.78%) are visible. Two methods of introducing a marking composition based on nanoaluminium and iron ore concentrate into the composition of the explosive “Granulite M” were studied. The marking of mixed explosives with a powdered fine marking composition by the first method, in amounts sufficient for uniform distribution in the composition of the explosive (at least 2%), leads to a change in the formulation composition. When using the second method, instantaneous precipitation of particles of nanoaluminum and iron ore concentrate was observed. In industrial conditions, this will lead to the need for a device for mechanical mixing of containers with liquid petroleum products. Thus when using finely dispersed metals and their alloys for marking of mixed explosives, it is fundamentally possible, provided they are introduced into explosive compositions through a liquid combustible component with constant stirring for uniform distribution. It is expedient to identify explosives marked in this way by X-ray spectral analysis by the presence of certain metal markers, and the remains of fragments at the site of the explosion - by the presence of oxides of marker metals.</em>https://www.ijnnonline.net/article_715066_e02f19c74068111be39849bd2b52f649.pdfIranian Nanotechnology SocietyInternational Journal of Nanoscience and Nanotechnology1735-700420220240501The Controllable Growth of CoNiCu Nanoalloy Electrodeposited from Electrolyte-Containing Alkyl Polyglucoside10311171506710.22034/ijnn.2024.1999452.2358ENSetiaBudiDepartment of Chemistry, Faculty of Mathematics and Sciences, Universitas Negeri Jakarta, Jl.

The FESEM analysis carried out on the as-prepared samples found that the morphology of nanoscale Co-Ni-Cu alloy particles was strongly influenced by the APG surfactant in the reaction. In a typical process, the morphology of Co-Ni-Cu particles was spherical with excellent size distribution of average size ca. 50 nm. It is in total contrast with those prepared in the absence of APG, of which is irregular shape particles of size ca. 100 nm as the dominant product. The composition analysis on the deposits found that the addition of the APG surfactant in the reaction may modify the ratio of the alloys to some extents, as the change in the co-electrodeposition potential become improbable in the system without the APG surfactant.</em>https://www.ijnnonline.net/article_715067_baa99bd0ec46233eb328fd4b3f3839da.pdfIranian Nanotechnology SocietyInternational Journal of Nanoscience and Nanotechnology1735-700420220240531A Procedure to Compare CNTFET and CMOS Technologies through the Design of a SRAM Cell: A Review11312771506810.22034/ijnn.2024.2021428.2472ENRobertoMaraniElectronic Devices Laboratory, Department of Electrical and Information Engineering, Polytechnic University of Bari, 70126, Bari, ItalyAnna GinaPerriElectronic Devices Laboratory, Department of Electrical and Information Engineering, Polytechnic University of Bari, 70126, Bari, Italy0000-0003-4949-987XJournal Article20240128 <em>In this paper we review in depth a procedure to compare the performance of CNTFET and MOSFET devices operating in sub-threshold region for ultra-low power applications.

However, the low lithium concentration in seawater (0.17 ppm) requires an efficient and selective method of lithium extraction. Although metal-organic frameworks (MOFs) are widely utilized for removing or extracting heavy metals from seawater, they have not been extensively employed for lithium extraction from such sources. This research used a bimetallic MOF-based adsorbent (MnO<sub>2</sub>@Co/Zn ZIF) to extract lithium ions from the solution. The effects of Li<sup>+</sup> concentration and contact time on adsorption were investigated. Based on kinetic studies, the pseudo-second-order model adequately represents the kinetic behavior of lithium adsorption. The thermodynamic study demonstrated lithium adsorption with MnO<sub>2</sub>@Co/Zn ZIF is endothermic, spontaneous, and physisorption. The adsorption process fitted well with the Freundlich isotherm (R<sup>2</sup>=0.994), and this isotherm showed the maximum adsorption capacity at room temperature to be 71.43 mg/g. The desorption process was carried out with an HCl solution and showed that MnO<sub>2</sub>@Co/Zn ZIF has excellent desorption ability. In addition, it was demonstrated that the adsorbent could be used for lithium adsorption after three cycles of regeneration. Moreover, MnO<sub>2</sub>@Co/Zn ZIF is a viable candidate for recovering large amounts of lithium ions from solutions, based on the results.</em>https://www.ijnnonline.net/article_715069_ceed56e4dac837ce464a644f4c6801e8.pdfIranian Nanotechnology SocietyInternational Journal of Nanoscience and Nanotechnology1735-700420220240501Contemporary Advances in Metal Oxide Doped Polypyrrole Composites: A Comprehensive Review14315971568910.22034/ijnn.2024.2005501.2391ENNandini V.IyerSymbiosis Institute of Technology, Symbiosis International (Deemed University), 412115, Lavale, Pune, IndiaDepartment of Applied Sciences, COEP Technological University, 411005, Pune, India0009-0000-4203-053XGanesh L.AgawaneDepartment of Chemistry, Faculty of Science and Technology, JSPM University, 412207, Pune, IndiaChandanPatelDepartment of Chemistry, Faculty of Science and Technology, JSPM University, 412207, Pune, IndiaJayant A.KherDepartment of Applied Sciences, COEP Technological University, 411005, Pune, IndiaShekhar D.BhameSymbiosis Institute of Technology, Symbiosis International (Deemed University), 412115, Lavale, Pune, India0000-0002-3430-1114Journal Article20230629<em> Intrinsically conducting polymers (ICPs) have revolutionized materials science with their versatile applications in electronics, sensors, and energy storage.
