Rapid synthesis using microwaves is a suitable technology that has great potential for use in industrial fields due to the significant reduction in reaction time, increase in product yield, and the use of safe heating sources. The heating method with the help of microwaves has attracted a lot of attention as a suitable method for the synthesis of metal nanostructures in the solution phase. This method has been used to synthesize many nanostructures such as Ag, Au, Pt, Pd and Au-Pd. Not only spherical nanoparticles, but plate, rod, wire, tube and dendritic nanostructures are prepared in a few minutes. Generally, nanostructures with smaller size, narrower size distribution and higher degree of crystallinity are prepared method compared to conventional oil bath heating methods. On the other hand, room temperature ionic liquids (RTILs) have attracted much attention in recent years. ILs can absorb microwaves and increase the reaction speed and decrease the reaction time. The large cations with high polarizability in ILs make these materials suitable solvents for absorbing microwaves. Therefore, the use of microwaves as a heat source along with ILs as a catalyst, solvent, additive, co-solvent and template leads to the creation of a fast and environmentally friendly method (MAIL) for the synthesis of various nanostructures.

At present, solar thermal energy systems suffer great losses due to heat transfer processes, therefore, the development of nanotechnology and its achievements such as various nanoparticles, has created high hopes to increase the efficiency of solar collectors through direct absorption of sunlight. In order to make optimal use of solar nanofluid systems, it is necessary to identify and study them. In this research, four different nanofluids have been synthesized, identified and evaluated. Two of them were water-based nanofluids and the other two were thermal oil-based nanofluids. Also, the optical properties of nanofluids were measured at room temperature with a spectrophotometer and compared with the base fluid. The optical properties, in addition to being measured at room temperature, have also been evaluated after heat treatment on nanofluids at high temperatures. This temperature increase is intended to recreate operating conditions for those closer to the actual applications. DLS measurements show a similar hydrodynamic average of 138 nm for the sample containing SDS and 135 nm for the sample containing SDS and PVP. Manuscript profile -

Plant disease management depends on pesticides and toxins that are potentially harmful to humans and the environment. Nanotechnology can offer benefits to pesticides, including reduced toxicity, improved reliability and durability and increased solubility in pesticides that are sparingly soluble in water. This paper examines two trends in the use of nanoparticles in controlling of phytopathogenic fungi: nanoparticles as protectors independently or as nanocarriers for fungicides. Despite the many potential benefits of nanoparticles, few nanoparticle-based products have been commercialized for agricultural applications. The lack of commercial applications can be explained by several factors, including the insufficient number of field studies and the lack of attention to the pest-host system. In other industries, nanotechnology has advanced rapidly, and it seems that the only way to continue advancing nanotechnology applications in agriculture is to understand the fundamental research questions and find scientific gaps for the rational and easy development of commercial nanoproducts.

Leaves of the Dionaea muscipula (venus flytrap) can capture insects, leaflets of Codariocalyx motorius and Helianthus annuus can rotate under exposure to sunlight, leaves of Mimosa pudica can collapse when shaken or touched and Chamaeleonidae or Octopoda change their color depending on the environmental condition or situation. These natural phenomena have attracted the attention of researchers for a long time, and various attempts have been made to imitate this behavior using synthetic materials. In this sense, the synthesis, properties, and application of stimuli-responsive polymers have become one of the most important research lines of polymer science. Smart polymers or stimuli-responsive polymers undergo large reversible changes, either physical or chemical, in their properties as a consequence of small environmental variations. They can respond to a single stimulus or multiple stimuli such as temperature, pH, electric or magnetic field, light intensity, biological molecules, etc., that induce macroscopic responses in the material, such as swelling/collapse or solution-to-gel transitions, depending on the physical state of the chains. The addition of nanofillers can enhance the performance of stimuli-responsive polymers (e.g., shape stabilization, shape recovery, self-healing ability) due to high specific surface area, nucleation effects, reinforcement effects, and intrinsic functions (e.g., thermal conductivity, electrical conductivity). This research work tries to provide a wide review of physical methods of nanomaterial and smart polymer nanocomposite preparation. Manuscript profile -

Tremendous advances in nanotechnology by introducing technologies with higher efficiency, lower price and environmentally friendly allow us to go beyond current options in providing energy for various systems. Renewable energies and nanotechnology are two areas that can have positive effects in the oil refining industry. Renewable energies such as solar, wind, water, geothermal and bioenergy can be used as alternative energy sources to provide electricity and heat needed by refineries and help to reduce dependence on fossil fuels. Nanotechnology plays a role in improving refining processes, increasing the efficiency and stability of equipment and catalysts, and cleaning the environment. For example, the use of nanocatalysts can increase the speed of chemical reactions and reduce energy consumption. Nanofilters can also be used in refinery wastewater treatment to separate pollutants with high precision. In general, these technologies can help increase productivity and reduce the environmental effects of refinery activities and are considered a big step towards sustainable development.

Of course, the potential dangers of some Nano-material could lead to environmental degradation or pollution. The rapid advances in Nano-technology have challenged traditional legislative regimes in both international law and national law, including in the field of the environment. The subject of this research is to investigate the legal gaps in nanotechnology, which has been done to determine the legal challenges in the use of this technology and also provide legal solutions. The present article is descriptive-analytical and finally, it has been concluded that if a coordinated effort is made between the various parts of the regulatory system at the national and international levels, it is possible to solve challenges and it can lead to the development of regulations at national and international levels. The development of new and special laws to eliminate the shortcomings of the existing regulatory system is one of the solutions. Manuscript profile -

Moreover, the gate diffusion input (GDI) technique has been successful in reducing complexity, area, and energy consumption in low-power circuit designs. In this technique, a wide range of complex logic functions can be implemented using only two transistors as the main block. In this study, a QCA-based GDI block is proposed using only 11 cells as a standard design unit that can be used to implement basic functions such as AND, OR, MUX, BUFFER, NOT and XOR in digital circuits. QCADesigner simulations of the functions in 18 nm technology indicate the superior performance of the proposed block with only one clock cycle delay in performing the operations. Moreover, the power consumption analysis of the designed circuits is performed using QCADesigner. The advantages of the proposed circuit compared to previous designs are 31% reduction in cell count, 50% smaller surface area, and 17% reduction in total energy loss. Manuscript profile -

This novel functionalized graphene oxide was characterized by FT-IR, XRD, FE-SEM, TEM analyses. Thereafter, the adsorption property of GO-GAA for Cd2+ ion removal from aqueous media was investigated. The effect of several factors such as pH and temperature on the Cd2+ adsorption was also studied. The maximum Cd2+ adsorption by GO-GAA occurs at 20°C, at pH=7. The synthesized nanoadsorbent also showed a good reusability, even after 10 cycles of adsorption-desorption using HNO3 as regenerating agent. Furthermore, applicability of synthesized nanoadsorbent for Cd2+ removal from industrial wastewater and well water samples inoculated with cadmium was investigated and over 82% efficiency was observed.
