“…[19] Europe's "chemical plants of tomorrow" are envisioned as compact container plants to speed up process development and offer as well as advantages for chemical production. [20] Those plants are mobile (Evonik's "Plants on Wheels [21] " and the "50% Idea [22] " of the German chemical industry and academia) and can utilize renewable energy (Evonik's "Fertilizing with the Wind [23] "). That opens the door to entirely new business models for distributed production at the local site of farming.…”

In the present study, a series of thermochemical equilibrium modeling was conducted to assess the thermodynamic potential of biomass conversion to ammonia using thermal and nonthermal plasma at small‐ and large‐scale production. The system was designed and evaluated for five different locations in Australia including the Northern Territory, South Australia, Western Australia, and New South Wales using local biomass feedstock. The equilibrium modeling showed that the pathway of biomass to biomethane using an anaerobic digestion reactor, biomethane to hydrogen using a thermal plasma reactor, followed by conversion of hydrogen to ammonia via a nonthermal plasma reactor is a plausible route, by which the exergy efficiency of the process can be as high as ~60%. It is identified that the thermal plasma reactor required two distinct zones at 3000°C < T < 4000°C and 1500°C < T < 2500°C. The first zone aims at converting electric energy into very high temperature thermal flow while the second one enables to split methane molecules into solid carbon and hydrogen. The new ammonia process is also assessed from the viewpoint of the current industrial transformation, being accelerated by the post‐COVID economy, which moves toward local, resilient, integrated and self‐sufficient production under the umbrella of an emerging fractal economy. With respect to local production, the developed process is designed for a quick response to farm use and on‐time production in view of the demands of modern ICT‐sensor based precision agriculture. The proposed process was found to be flexible (“resilient”) against production scale, geographical location, price and type of feedstock, and source of renewable energy. The system was found to be flexible against different feedstock such as spent grape marc, mustard seed, bagasse, piggery and poultry. The system can be self‐sustained up to ~80% at T = 3500°C; with the thermal plasma reactor‐zone 2 producing the electricity requirements for the nonthermal plasma via a steam turbine power block. Finally, the system it is investigated to which degree the system is adaptable to local production, self‐sufficient, and circulatory.

“…Nanoformulation or encapsulation of insecticides, herbicides, fungicides and bactericides with nanomaterials holds enormous potential for decreasing chemical pesticides doses, increasing crop production and promoting sustainable development [ 11 , 22 ]. Nanocarriers of nanopesticides include polymeric NPs (such as chitosan and solid lipids), inorganic nonmetallic NPs (such as silica NPs and nanoclays) and metallic NPs (such as Cu NPs and ZnO NPs) [ 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. Several studies have shown that nanotype insecticides are more efficient at killing pests and less likely to cause side effects on humans [ 35 ].…”

With the frequent occurrence of extreme climate, global agriculture is confronted with unprecedented challenges, including increased food demand and a decline in crop production. Nanotechnology is a promising way to boost crop production, enhance crop tolerance and decrease the environmental pollution. In this review, we summarize the recent findings regarding innovative nanotechnology in crop production, which could help us respond to agricultural challenges. Nanotechnology, which involves the use of nanomaterials as carriers, has a number of diverse applications in plant growth and crop production, including in nanofertilizers, nanopesticides, nanosensors and nanobiotechnology. The unique structures of nanomaterials such as high specific surface area, centralized distribution size and excellent biocompatibility facilitate the efficacy and stability of agro-chemicals. Besides, using appropriate nanomaterials in plant growth stages or stress conditions effectively promote plant growth and increase tolerance to stresses. Moreover, emerging nanotools and nanobiotechnology provide a new platform to monitor and modify crops at the molecular level.

The environmental crisis, due to the rapid growth of the world population and globalisation, is a serious concern of this century. Nanoscience and nanotechnology play an important role in addressing a wide range of environmental issues with innovative and successful solutions. Identification and control of emerging chemical contaminants have received substantial interest in recent years. As a result, there is a need for reliable and rapid analytical tools capable of performing sample analysis with high sensitivity, broad selectivity, desired stability, and minimal sample handling for the detection, degradation, and removal of hazardous contaminants. In this review, various gold–carbon nanocomposites-based sensors/biosensors that have been developed thus far are explored. The electrochemical platforms, synthesis, diverse applications, and effective monitoring of environmental pollutants are investigated comparatively.
