“…The pre-ligand exchanged quantum dots' size, as determined by DLS data, is approximately 9.429 nm. which is larger than the size that we estimated using the reference's equation [26]. Given that the DLS experiment was carried out three weeks after the quantum dots were created, the size difference could be the result of the quantum dots being combined between the two experiments.…”

“…By developing a thorough understanding between time-dependent and classical density function theorems, different luminescent properties, such as UV spectra, IR spectra, etc. are investigated for metal-organic framework (MOF-5) [24][25] [26]. Svetlana V. Kilina and colleagues have proposed a novel modification of the fundamental electron-photon interaction to improve the efficiency of CdSe and PbSe QD based solar cells by generating multiple bottleneck relaxations between electronic and vibrational frequencies.…”

Recent advancement in the field of nano-structured electronic devices has finely tuned up various progenition and manufacturing process of Quantum Dots that can directly harvest energy from solar power. Duly acknowledging different types of procuring processes, the paper primarily focuses on eight different CdSe (Cadmium Selenide) Quantum DOT samples which are initially synthesized in the material testing lab from the available precursor. Structural and electrical properties of these synthesized nano materials are inspected using DFT (Density function theory) based commercial tool - ESPRESSO. Later on, different photo luminous spectroscopic methods are used to understand the optical characteristics of the CdSe based nanomaterials. Light scattering method is applied to comprehend greater insights about the same sampled nano materials based on different parameters such as – polydispersity index (PI), Stokes shift analysis, zeta potential etc. Finally, the most equipped CdSe Quantum DOT sample is chosen for future purpose and a sensitive case study covering diverse advantages, disadvantages and future challenges of QDOTs is carried out.

This research paper investigates the optimization of radiation performance of a plasma-based bioconvective nanofluid integrated Magneto-hydrodynamic (MHD) micropump for radiative oncology. It addresses a literature gap by analysing the radiative impact of blood-based hybrid nanofluids in MHD micropumps. Three blood-based bio-convective radiating hybrid nanofluids – blood – Pt, blood – Au and blood - MWCNT are studied to understand their radiation behaviour in MHD pump while being employed as transportation medium. The investigation employs two non-dimensional parameters, namely Rd (Radiation number) and Ha (Hartmann number), to examine the fluid dynamics, magnetic characteristics, and electrical properties of the MHD micropump. The temperature gradient, velocity distribution, and pressure drop along the flow channel are examined within the specified range of Rd and Ha. Magnetic flux density (MFD) and electric flux intensity (EFI) are evaluated to understand nanoparticle behaviour during drug delivery and blood transportation. Findings highlight that MWCNT and Pt are the most efficient bioconvective nanoparticles for plasma transportation under high radiative conditions. MWCNT-based blood flow exhibits desirable characteristics, including sufficient intake pressure and minimal pressure drop. Coherence between radiation flux and electromagnetic flux reduces pumping power and ensures uniform heat dissipation for improved drug delivery. Au nanoparticles provide maximum magnetic flux density, even in highly radiative environments, making them suitable for applications like embedded chemotherapy or cell treatment. Au nanoparticles maintain moderate electrical flux intensity with a minimal drop, particularly at higher radiative environments influenced by the Radiation number. Conclusively, it has been identified that MWCNT and Au are superior nanofluids for advanced radiative oncological treatments. These nanofluids have the potential to enhance plasma transportation, thermal regulation, and aetilogical disease management. The present study provides significant findings on enhancing the radiation performance in MHD micropumps through utilization of blood-based hybrid nanofluids, thereby offering potential advantages to the domain of biomedical engineering.

This research paper investigates the optimization of radiation performance of a plasma-based bioconvective nanofluid integrated Magneto-hydrodynamic (MHD) micropump for radiative oncology. It addresses a literature gap by analysing the radiative impact of blood-based hybrid nanofluids in MHD micropumps. Three blood-based bio-convective radiating hybrid nanofluids—blood—Pt, blood—Au and blood—MWCNT are studied to understand their radiation behaviour in MHD pump while being employed as transportation medium. The investigation employs two non-dimensional parameters, namely Rd (Radiation number) and Ha (Hartmann number), to examine the fluid dynamics, magnetic characteristics, and electrical properties of the MHD micropump. The temperature gradient, velocity distribution, and pressure drop along the flow channel are examined within the specified range of Rd and Ha. Magnetic flux density (MFD) and electric flux intensity (EFI) are evaluated to understand nanoparticle behaviour during drug delivery and blood transportation. Findings highlight that MWCNT and Pt are the most efficient bioconvective nanoparticles for plasma transportation under high radiative conditions. MWCNT-based blood flow exhibits desirable characteristics, including sufficient intake pressure of 4.5 kPa and minimal relative pressure drop of 34%. Coherence between radiation flux and electromagnetic flux reduces pumping power and ensures uniform heat dissipation for improved drug delivery. Au nanoparticles provide moderate magnetic flux density with least fluctuation within the range of Ha and Rd number (2.57 T to 4.39 T), even in highly radiative environments (such as—Rd = 4, Rd = 5), making them suitable for applications like embedded chemotherapy or cell treatment. Au nanoparticles maintain moderate electrical flux intensity with a minimal drop of 16nA, particularly at higher radiative environments influenced by the Radiation number (Rd = 4 to Rd = 5) while Ha values from Ha = 2 to Ha = 4. Conclusively, it has been identified that MWCNT and Au are superior nanofluids for advanced radiative oncological treatments. These nanofluids have the potential to enhance plasma transportation, thermal regulation, and aetilogical disease management. The present study provides significant findings on enhancing the radiation performance in MHD micropumps through utilization of blood-based hybrid nanofluids, thereby offering potential advantages to the domain of biomedical engineering.
