“…Carbon nanotubes (CNT) have attracted much interest owing to their unique physicochemical and mechanical properties and due to their potential applications such as electron field emitters, biosensors, electrode materials for solar cells, and as components in fuel cells [1,2]. Many synthetic methods, such as arc-discharge, laser ablation, chemical vapor deposition (CVD) and spray pyrolysis are directly or indirectly based on petroleum products as a precursor [3,4].…”

The synthesis of carbon nanomaterials (CNMs) by a chemical vapor deposition method using three different plant oils as precursors is presented. Because there are four parameters involved in the synthesis of CNM (i.e., the precursor, reaction temperature of the furnace, catalysts, and the carrier gas), each having three variables, it was decided to use the Taguchi optimization method with the 'the larger the better' concept. The best parameter regarding the yield of carbon varied for each type of precursor oil. It was a temperature of 900°C + Ni as a catalyst for neem oil; 700°C + Co for karanja oil and 500°C + Zn as a catalyst for castor oil. The morphology of the nanocarbon produced was also impacted by different parameters. Neem oil and castor oil produced carbon nanotube (CNT) at 900°C; at lower temperatures, sphere-like structures developed. In contrast, karanja oil produced CNTs at all the assessed temperatures. X-ray diffraction and Raman diffraction analyses confirmed that the nanocarbon (both carbon nano beads and CNTs) produced were graphitic in nature.

Abstract:In this paper an alkaline fuel cell (AFC), which was developed using nickel electro-catalyst for hydrogen oxidation process is reported. Pumice plate with porosity of 71% was used as an electrode substrate, and it was made by depositing conducting carbon using CVD process. Nickel metal was electroplated over the carbon deposited pumice plate. Carbon nanotubes were deposited over the electroplated nickel to prevent nickel from getting corroded by KOH solution (electrolyte). It is observed that 1.9 wt% nickel gives the best stability giving 300 mA/cm 2 current density at 980 mV as hydrogen dissociation voltage. I-E characteristics and chronoamperometric studies of half and full cells are also reported.

“…Yao et al [ 201 ] used fluorescent nanoprobes of silica NPs for the detection of bacterial spot disease in Solanaceous plants caused by Xanthomonas axonopodis . Similarly, Sharon and Sharon [ 202 ] synthesized carbon nanomaterial-based chemical sensors for the detection of pesticide residues in plants. A nano-sensing system turns conventional agriculture into a precision farming system, and real-time monitoring has reduced the over-application of fertilizers and pesticides, which is helpful in protecting the environment from contamination [ 203 ].…”

There is a need for a more innovative fertilizer approach that can increase the productivity of agricultural systems and be more environmentally friendly than synthetic fertilizers. In this article, we reviewed the recent development and potential benefits derived from the use of nanofertilizers (NFs) in modern agriculture. NFs have the potential to promote sustainable agriculture and increase overall crop productivity, mainly by increasing the nutrient use efficiency (NUE) of field and greenhouse crops. NFs can release their nutrients at a slow and steady pace, either when applied alone or in combination with synthetic or organic fertilizers. They can release their nutrients in 40–50 days, while synthetic fertilizers do the same in 4–10 days. Moreover, NFs can increase the tolerance of plants against biotic and abiotic stresses. Here, the advantages of NFs over synthetic fertilizers, as well as the different types of macro and micro NFs, are discussed in detail. Furthermore, the application of NFs in smart sustainable agriculture and the role of NFs in the mitigation of biotic and abiotic stress on plants is presented. Though NF applications may have many benefits for sustainable agriculture, there are some concerns related to the release of nanoparticles (NPs) from NFs into the environment, with the subsequent detrimental effects that this could have on both human and animal health. Future research should explore green synthesized and biosynthesized NFs, their safe use, bioavailability, and toxicity concerns.
