“…As a hydroxylated metal oxide, Fe 3 O 4 NPs favored to adsorb weak acidic CO 2 molecule and its H 2 CO 3 form in fermentation media. Magnetite made carbonates, bicarbonates and carboxylates, efficiently, with CO 2 , which facilitated a good adsorption capacity [9]. Moreover, the decorated cells had the improved carbon fixation yield, suggesting that the cell-NPs assembly did not experience a mass transfer problem.…”

“…In their further research, magnetic Fe 3 O 4 decorated graphite nanoplatelets can be regarded as cost effective CO 2 adsorbent, which facilitates a good adsorption capacity [8]. In the report of Tamilarasan and Ramaprabhu [9], polyaniline/magnetite nanocapsules (PANI/MNCs) adsorbed 42 mmol/g of CO 2 in the initial 90 min at room temperature. Therefore, the modification via magnetite nanoparticles can enhance the CO 2 adsorption capacity of many chemical adsorbents.…”

“…By coating with PAni, the agglomerations of particles were supposed to declined, leading to higher surface area ratio of nanocomposites. The magnetization reduction at a particle surface as well as charge elevation at the surface of nanocomposites may lead to an antiagglomeration effect of the PAni layer [30,31]. Figure 5 shows the XRD patterns of MNPs and PAni/ MNPs showing 7 peaks which characterized for magnetite crystal of 111, 220, 311, 400, 422, 511, and 440 planes.…”

In this study, nanocomposites composed of magnetite nanoparticles (MNPs) coated with polyaniline fabricated by in situ polymerization were prepared for arsenic adsorption. Properties of particular MNPs and their nanocomposites were characterized with scanning electron microscopy, X-ray diffraction spectroscopy, and Fourier transform infrared spectroscopy. The As(III) concentration before and after adsorption on nanocomposites was detected by atomic absorption spectroscopy method and then compared with the results measured by a self-developed potentiostat system with anodic stripping voltammetry method. The polyaniline coating resulted in an improvement for As(III) adsorption ability of magnetite nanoparticles, and among the three compositions of PAni/MNP nanocomposites, the 5 wt% PAni showed the highest capability of As(III) adsorption (or removal) of 50 mg/g. Performing pH investigation, the concentration of remaining As decreased when pH increased from 2 to 5 and reached saturation value at higher pH. Above all, the electronic device can be integrated with As(III) removal system using PAni/MNP nanocomposites, proving to act as an independent monitoring system, and even more the adsorbent on the composites could be removed and the recyclability of the material was also investigated.

GRICULTURE provides food for humans, directly and indirectly. ….. Given the increasing world population, it is necessary to use the modern technologies such as nanotechnology in agricultural sciences. Nanotechnology has been defined as relating to materials, systems and processes which operate at a scale of 100 nanometers (nm) or less. Nanotechnology has many applications in all stages of production, processing, storing, packaging and transport of agricultural products. Nanotechnology will revolutionize agriculture and food industry by innovation of new techniques such as: precision farming techniques, enhancing the ability of plants to absorb nutrients, more efficient and targeted use of inputs, disease detection and control diseases, withstand environmental pressures and effective systems for processing, storage and packaging, increase the efficiency of applied fertilizer with the help of nano clays and zeolites and restoration of soil fertility by releasing fixed nutrients. Research on smart seeds programmed to germinate under favourable conditions with nanopolymer coating are encouraging. Nanoherbicides are being developed to address the problems in perennial weed management and exhausting weed seed bank. Efficiency of medicine increases by use of nano particle in animal sciences. Silver and iron nano particles are used in the treatment and disinfection of livestock and poultry. Levels of environment pollution can be evaluated quickly by nano smart dust and gas sensors.
