Special Issue Information

Dear Colleagues,

The human quest for knowledge in the smaller than the smallest dimensions of length has laid the foundation of nanotechnology which deals with the synthesis, characterization and applications of nano-size materials ranging from 1 to 100 nm. Recent advancements in this field have resulted in the development of a variety of applied nanomaterials and novel technologies which have attracted billions of dollars of investment. Particularly, the astonishing changes in the physicochemical properties and distinct enhancement in the surface reactivity of materials in the nano-regime have fascinated scientists and researchers across several fields including material science. Besides, several diverse nanomaterials have gained immense popularity in different fields including molecular biology, physics, organic and inorganic chemistry, medicine, etc. Indeed, nanomaterials have become an integral part of both basic, applied and advance sciences that have also been combined with various functional materials to obtain nanocomposite which delivers enhanced properties then their single counterparts. Till date different types of atomic and/or molecular structures have been transformed into functional nanomaterials including inorganic metals and metal oxides, organic compounds like dendrimers, polymers, etc., and other biomolecules like liposomes, etc. These nanomaterials have been applied for a variety of applications including catalysis, imaging, drug delivery, agricultural, biotechnological applications and so on. The formation of novel nanomaterials is mainly dependent on the type of synthetic method which is essential for the design and synthesis of desired shapes, dimensions and size of nanomaterials. Moreover, the composition, architecture, facet, size and dimensionality also determine the properties and functionalities of nanomaterials. Despite of the realization of abundant synthetic routes for the preparation of nanomaterials, it is still challenging to achieve cost-effective and large synthesis of advance functional nanomaterials with novel properties. Therefore, in this Special Issue about ‘’Advances in Nanomaterials’ Formation, Characterization and Applications’’, we invite the submissions of original research and review articles covering latest innovation in the designing and realization of advance nanomaterials for diverse applications. Particularly, we are more interested in the research on the development of novel synthetic approaches for the preparation of innovative nanomaterial with novel structures and/or reconfigurable functional materials. Additionally, development of nanomaterials and nanocomposites using sustainable and green approaches will also be of great interest.

Topics to be covered include (but are not limited to)

  • Design and synthesis of nanomaterials and nanocomposites using diverse approaches
  • Investigation on the relations between the nature, size, shape, architecture of nanostructures and their physicochemical properties
  • Characterization of nanomaterials and nanocomposites using advance techniques
  • Exploring the fundamental aspects of physical and chemical properties of nanomaterials and their composites
  • Theoretical simulation and computational modelling to explore fundamental understanding, prediction, and design of nanomaterials and nanocomposites
  • Nanomaterials and nanocomposites based device fabrications and their multifunctional advance applications including catalytical, biological, medicinal, sensing and so on.

Semiconducting nanomaterials based heterogeneous photocatalysis represent a low-cost, versatile technique for environmental remediation, including pollution mitigation, energy management and other environmental aspects. Herein, we demonstrate the syntheses of various heterogeneous photocatalysts based on highly reduced graphene oxide (HRG) and vanadium oxide (VOx)-based nanocomposites (HRG–VOx). Different shapes (rod, sheet and urchin forms) of VOx nanoparticles were successfully fabricated on the surface of HRG under solvo-/hydrothermal conditions by varying the amount of water and ethanol. The high concentration of water in the mixture resulted in the formation of rod-shaped VOx nanoparticles, whereas increasing the amount of ethanol led to the production of VOx sheets. The solvothermal condition using pure ethanol as solvent produced VOx nano-urchins on the surface of HRG. The as-prepared hybrid materials were characterized using various spectroscopic and microscopic techniques, including X-ray diffraction, UV–vis, FTIR, SEM and TEM analyses. The photocatalytic activities of different HRG–VOx nanocomposites were investigated for the photodegradation of methylene blue (MB) and methyl orange (MO). The experimental data revealed that all HRG–VOx composite-based photocatalysts demonstrated excellent performance toward the photocatalytic degradation of the organic dyes. Among all photocatalysts studied, the HRG–VOx nanocomposite consisting of urchin-shaped VOx nanoparticles (HRG–VOx-U) demonstrated superior photocatalytic properties towards the degradation of dyes.

Abstract
In this study, ZnO nanoparticles (NPs) were synthesized in the presence of almond oil at various molar ratios of zinc acetate and sodium hydroxide, including 0.5:1, 0.75:1, 1:1, 1.25:1, and 1.5:1, to obtain pH values of 11, 10, 9, 8, and 7, respectively. [...] Read more.
In this study, ZnO nanoparticles (NPs) were synthesized in the presence of almond oil at various molar ratios of zinc acetate and sodium hydroxide, including 0.5:1, 0.75:1, 1:1, 1.25:1, and 1.5:1, to obtain pH values of 11, 10, 9, 8, and 7, respectively. The XRD results revealed that ZnO NPs exhibit a hexagonal structure, with high crystallinity. SEM results showed that dense and large sized ZnO NPs were formed at pH 11, and relatively small (~30–40 nm) NPs were obtained at pH 9. The size distribution can be explained in terms of the presence of OH ions at different pH levels. However, the larger size of the NPs at pH 7 compared to those at pH 8–11 were due to the coalescence of NPs suitable for antioxidant/antibacterial activities. ZnO NPs demonstrated a high degradation efficiency (~93%) in 90 min, with a high rate constant for Methyl Orange (MO), which is better than the previously reported rate. The larger sized almond oil capped ZnO NPs also showed excellent radical scavenging activity (94%) and are proven to be good carriers to resist Escherichia coli (E. coli) bacteria. Full article
