“…No additional peak was observed in the XRD pattern thereby con-rming the purity of the synthesized FeS 2 sample. 22,23,[32][33][34][35] Similar peaks were observed in the diffraction pattern of FeS 2 / PA, thus indicating that the while the polymerization of polyaniline took place, the FeS 2 particles were not dissolved in the acidic medium. By the Scherrer's equation (D ¼ Kl/B cos q), (where l ¼ wave length of X-ray, q the diffraction angle, K the shape factor and B ¼ B…”

“…Previous studies involving iron NPs in the soil matrix after seed germination have reported a dosedependent relationship between the iron NP dosage and iron content within different parts of the plant [10,16,42]. However, when applied as only seed treatment, Srivastava et al found no significant difference in iron content in spinach plant leaves with a different iron pyrite (FeS 2 ) NP dosing [12,43]. Our study also confirms the absence of a significant dose-dependent iron content relationship when applying NPs in a "modified seed presoak" strategy.…”

There is an emerging scientific interest in the use of nanoparticle fertilizers for enhanced agricultural and bioenergy crop production to meet the growing food and energy demands of the world. The objective of designing the nanoparticle fertilizers is to effectively deliver the required nutrients for the plants without adding large quantities of fertilizer to the environment. However, most reports on nanoparticle fertilizers so far, involved the addition of nanoparticles to the hydroponic system or the soil. In this study, we report a new modified seed presoak strategy using a drop of Fe-enriching hematite nanoparticle dispersion to enhance plant growth and production in four different legume species, i.e., chickpea, green gram, black bean, and red bean. The hematite nanoparticle fertilizer drop promoted a 230-830% increase in plant growth with green gram showing the highest increase, based on our prolonged and statistically reliable growth studies. In general, we observed an increase in the survival span of plants, a twofold increase in fruit production per plant, nearly two times faster fruit production, and healthy secondgeneration plants with the nanoparticle treatment; however, there were slight species-specific variations. We used a novel multimodal material characterization approach combining three techniques, hyperspectral imaging, Fourier transform infrared spectroscopy (FTIR), and inductively coupled plasma optical emission spectroscopy (ICP-OES), to evaluate the internalization and transport of the nanoparticle fertilizer within the plants. Our results indicated that the hematite nanoparticles were transported through the roots and stems and were localized in the leaves after 10 days of growth in pots of soil. Therefore, the modified seed presoaking method using a drop of hematite nanoparticle will be highly attractive in enhancing plant growth and health, while minimizing environmental impacts.

Transition metal sulfides (TMSs) are of special interest in energy conversion and storage devices. Amongst all sulfides, fool's gold or iron pyrite (FeS 2 ) is potentially an attractive candidate for photovoltaic applications. Iron pyrite has risen to prominence due to its distinct properties and abundance in nature to meet the large scale needs. It is considered as environmentally benign solar absorber material with high absorption coefficient, α > 6 x10 5 cm À 1 for λ � 700 nm and suitable energy bandgap (E g = 0.95 eV). Numerous physical and chemical methods have been employed to deposit nanocrystalline pyrite thin films directly from source materials or indirectly by sulfuration. This review gives an overview of pyrite as a low cost photovoltaic absorber material for contemporary solar cell structures. In addition, practical approaches like the rational design of nanocomposites, band gap engineering and nanostructure synthesis of pyrite for improving its properties particularly photovoltaic properties are also deliberated. Moreover, limitations, challenges, remedies and prospects of pyrite as potential photovoltaic material are also reviewed to further advance the development of pyrite-based solar cell configurations.[a] Dr.at a low precursor concentration, pyrite nanocubes (125-250 nm in 20-180 min) were obtained due to low nuclei concentration and slow growth (diffusion limited) in quasiequilibrium.
