Special Issue Information

Dear Colleagues,

Current advancements in the green synthesis and application of nanotechnology and nanoscience have resulted in new nanomaterials, which may pose health and environmental risks. Furthermore, it is important to optimize ecologically friendly procedures for creating metal and metal-oxide nanoparticles. This Special Issue will provide readers with up-to-date information on the recent progress in the thermal analysis of metals, ceramics, and polymers from different perspectives of thermodynamics, spanning materials sciences, catalysis, energy conversion, corrosion, and geochemistry.

The Special Issue will cover topics including, but not limited to:

  • Synthesis (e.g., green synthesis, organic, synthetic biology, inorganic);
  • Catalysis (e.g., homogeneous, H2 production, CO2 reduction, enzyme, heterogeneous, wastewater treatment, whole cell);
  • Energy (e.g., fuels, renewable energy, fuel cells, photovoltaics, energy conversion, energy carriers);
  • Applications (e.g., electronics, dyes, coatings, consumer products, photocatalysis, pharmaceuticals, preservatives, building materials, chemicals for industry/agriculture/mining).

There have been some reports demonstrating the biogenic synthesis of silver nanoparticles (AgNPs) using Calotropis procera (CP) plant extract; however, detailed in-depth debriefing of the vital synthesis parameter for rapid, facile, efficacious synthesis at varied temperatures with effectual characterization of nanoparticles and biomimetic attribute is lacking. This study presents a comprehensive demarcation of the sustainable fabrication of biogenic C. procera flower extract capped and stabilized silver nanoparticles (CP-AgNPs) synthesis with thorough phytochemical characterization and potential biological application. The results revealed that the successful synthesis of CP-AgNPs was instantaneous with the maximum intensity of the plasmonic peak ~400 nm, while morphological results revealed the cubic shape of nanoparticles. CP-AgNPs were found to present stable, well-dispersed, uniform, high anionic zeta potential, and crystalline nanoparticles with a crystallite size of ~23.8 nm. The FTIR spectra indicated that CP-AgNPs were properly capped by the bioactive of C. procera. Moreover, the synthesized CP-AgNPs exhibited hydrogen peroxide scavenging efficacy. In addition, CP-AgNPs showed antibacterial and antifungal activity against pathogenic bacteria. CP-AgNPs displayed significant in vitro antidiabetic and anti-inflammatory activity. An efficient and convenient approach for synthesizing AgNPs using C. procera flower has been developed with enhanced biomimetic attributes that may be further utilized for water treatment, biosensors, biomedicine, and in allied science.

ZnO nanoparticles were synthesized using lemon juice and zinc nitrate (1:1) through the green method. The structure of the biosynthesized ZnO nanoparticles was analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). The morphology and the size of ZnO nanoparticles were elucidated by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The powder was highly dispersed and irregularly shaped and the size of the nanoparticles ranged from 28 to 270 nm, depending on the shape of the particles. Thermal conductivity of the biosynthesized ZnO PG/W mixture 40:60 (v/v) nanofluids was measured within the temperature range of 20–70 °C. Experimental results revealed a linear increase in thermal conductivity with the rise of temperature and volume fraction. The enhancement of this parameter with temperature was probably due to the different shapes of the former agglomerates. They were broken by the thermal energy in aggregates of different forms. A correlation of these structures with temperature was established. Finally, an empirical model was developed for predicting thermal conductivity with particle volume fraction and temperature.
