Special Issue Information

Dear Colleagues,

This Special Issue of Nanomaterials will cover the most recent advances from experimental and theoretical studies in functionalization strategies for nanostructured platforms. The demand of engineered nanostructures has increased in the recent years, boosted by, e.g., the need for novel concepts in energy harvesting and storage, in sensing for diffuse environmental monitoring and health screening, as well as by the increasing impact of the IoT, demanding portability and self-powering. One way to engineer nanostructured materials is through functionalization, which can be achieved in different ways once a nanostructured platform has been created. Among these methods, the most popular rely on the addition of nanoparticles, nanorods, nanosheets of metals, metal oxides, semiconductors, and carbon-based nanomaterials. Another promising functionalization method is represented by the growth of ultrathin layers, including molecular layers, on nanostructured platforms leading to the formation of heterojunctions.

This Special Issue calls for papers on all experimental and theoretical studies in various aspects of nanostructured platform engineering through functionalization strategies. Experimental studies include the functionalization of nanostructured platforms and the characterization of their physical and chemical properties, including in situ, operando, and time-resolved spectroscopy probes, as well as the testing of device performances. Theoretical studies include ab initio simulation of the physical and chemical properties of nanostructures, surfaces, and heterointerfaces.

Pigments can retain their color for many centuries and can withstand the effects of light and weather. The paint industry suffers from issues like aggressive moisture, corrosion, and further environmental contamination of the pigment materials. Low-cost, long-lasting, and large-scale pigments are highly desirable to protect against the challenges of contamination that exist in the paint industry. This exploratory study reinforces the color and thermal stability of industrial-grade (IG) magnetite (Fe3O4). IG Fe3O4 pigments were further considered for surface treatment with sodium hexametaphosphate (SHMP). This metaphosphate hexamer sequestrant provides good dispersion ability and a high surface energy giving thermal and dust protection to the pigment. Various physicochemical characterizations were employed to understand the effectiveness of this treatment across various temperatures (180–300 °C). The X-ray diffraction, Raman, and X-ray photoelectron spectroscopy techniques signify that the SHMP-treated Fe3O4 acquired magnetite phase stability up to 300 °C. In addition, the delta-E color difference method was also adopted to measure the effective pigment properties, where the delta-E value significantly decreased from 8.77 to 0.84 once treated with SHMP at 300 °C. The distinct color retention at 300 °C and the improved dispersion properties of surface-treated Fe3O4 positions this pigment as a robust candidate for high-temperature paint and coating applications. This study further encompasses an effort to design low-cost, large-scale, and thermally stable pigments that can protect against UV-rays, dust, corrosion, and other color contaminants that are endured by building paints.

Recently, one-dimensional (1D) nanostructures have attracted the scientific community attention as sensitive materials for conductometric chemical sensors. However, finding facile and low-cost techniques for their production, controlling the morphology and the aspect ratio of these nanostructures is still challenging. In this study, we report the vapor-liquid-solid (VLS) synthesis of one dimensional (1D) zinc oxide (ZnO) nanorods (NRs) and nanowires (NWs) by using different metal catalysts and their impact on the performances of conductometric chemical sensors. In VLS mechanism, catalysts are of great interest due to their role in the nucleation and the crystallization of 1D nanostructures. Here, Au, Pt, Ag and Cu nanoparticles (NPs) were used to grow 1D ZnO. Depending on catalyst nature, different morphology, geometry, size and nanowires/nanorods abundance were established. The mechanism leading to the VLS growth of 1D ZnO nanostructures and the transition from nanorods to nanowires have been interpreted. The formation of ZnO crystals exhibiting a hexagonal crystal structure was confirmed by X-ray diffraction (XRD) and ZnO composition was identified using transmission electron microscopy (TEM) mapping. The chemical sensing characteristics showed that 1D ZnO has good and fast response, good stability and selectivity. ZnO (Au) showed the best performances towards hydrogen (H2). At the optimal working temperature of 350 °C, the measured response towards 500 ppm of H2 was 300 for ZnO NWs and 50 for ZnO NRs. Moreover, a good selectivity to hydrogen was demonstrated over CO, acetone and ethanol. Full article
