The metabolic activity of the fruits continues even after harvest,which results in the loss of bioactive compounds,a decrease in the quality of the fruits,softening and browning,among other negative effects.The use of certain elements such as silicon can improve postharvest quality,since it is involved in the metabolic,physiological and structural activity of plants,moreover can increase the quality of the fruits.In addition,nanotechnology has had a positive impact on crop yield,nutritional value,fruit quality and can improve antioxidant activity.For these reasons,the use of beneficial elements such as silicon in the form of nanoparticles can be a viable option to improve the characteristics of the fruits.In the present study was evaluated the application of potassium silicate(125,250 and 500 mg L^(−1))and SiO_(2) nanoparticles(125,250 and 500 mg L^(−1))during the development of the crop.The results showed that the application of silicon(potassium silicate and silicon nanoparticles)increased the content of total soluble solids(up to 15.6%higher than control),titratable acidity(up to 38.8%higher than control),vitamin C(up to 78.2%higher than control),phenols(up to 22%higher than control),flavonoids(up to 64.6%higher than control),and antioxidant activity in lipophilic compounds(up to 56.2%higher than control).This study suggests that the use of silicon can be a good option to increase the content of bioactive compounds in cucumber fruits when they are applied during the development of the crop.

The use of nanomaterials has spread and has been applied in different industries,including agriculture.Here,the possibilities presented by NMs are very varied,from the biostimulation of favorable responses,or the control of pests and diseases,to the monitoring of characteristics of interest with the use of nanosensors.Particularly the biostimulation of agricultural crops with the use of nanomaterials is very relevant,since from this process stress tolerance,higher content of biocompounds,etc.,can be induced.Although the positive impacts on crops are clear,there is not enough information to determine the long-term impacts,both on ecosystems and on human health.

Owing to the development of material science,nanotechnology and optical imaging techniques,theranostic agents that can be excited by near-infraredⅠ/Ⅱ(NIRⅠ/Ⅱ;NIRⅠ,λ=700-900 nm;NIRⅡ,λ=1000-1700 nm)light and/or emit fluorescence within these ranges are gaining momentum in the biomedical field.Compared to ultraviolet and visible light,the use of excitation light sources or fluorescent emissions in the NIRⅠ/Ⅱwindows holds several advantages.

In recent years, the world of science has started to produce advanced materials and technology in the nanoscale, which known as nanotechnology. The use of nanotechnology has become wide spread in all branches of science, one of the important branches is the field of transportation. The application of nanotechnology in pavements showed great promise and the potential to change commonly used materials, which makes transportation more efficient, smart looking, stronger and durable that all lead to the extension of their life cycle of the roads. So, there is an essential need to prepare advanced nanotechnology tools and detection systems contain very recent instruments needed for nanotechnology studies, since the physical, chemical and biological properties of the material at nanoscale differ in fundamental and valuable ways from that at normal scale. In this work the different techniques in measuring and detection techniques in nanotechnology will be discussed the method of operation and accuracy of each technique will be evaluated, the main applications of each technique in industrial and construction field will be evaluated.

In this paper, a reliable algorithm based on mixture of new integral transform and homotopy perturbation method is proposed to solve a nonlinear differential-difference equation arising in nanotechnology. Continuum hypothesis on nanoscales is invalid, and a differential-difference model is considered as an alternative approach to describing discontinued problems. The technique finds the solution without any discretization or restrictive assumptions and avoids the round-off errors. Comparison of the approximate solution with the exact one reveals that the method is very effective. It provides more realistic series solutions that converge very rapidly for nonlinear real physical problems.

The detection of trace levels of chemical, biological and other analytes has many important applications, including industry, forensics and environmental monitoring. Detection Journal is an international journal dedicated to the latest advancement of all areas that are related to detection. nanotechnology based detection techniques may provide major advantages of low detection limits and rapid testing. This may allow scientists to know early about the case and provide the potential of stopping the problem at earlier stages.

nanotechnology has attracted a great attention in enhancing oil recovery(EOR)due to the costeffective and environmental friendly manner.The size of nanoparticles for EOR usually is in a range of 1e100 nm,which may slightly differ from various international organisations.Nanoparticles exhibit significantly different properties compared to the same fine or bulk molecules because of much higher concentration of atoms at their surface as a result of ultra-small size.In particular,one of the most useful and fascinating properties of these particles is to creating a massive diffusion driving force due to the large surface area,especially at high temperatures.Previous studies have shown that nanoparticles can enhance oil recovery by shifting reservoir wettability towards more water-wet and reducing interfacial tension,yet this area is still open for discussion.It is worth noting that the potential of nanoparticles to reduce the oil viscosity,increase the mobility ratio,and to alter the reservoir permeability has not been investigated to date.Depending on the operational conditions of the EOR process,some nanoparticles perform more effectively than others,thus leading to different levels of enhanced recovery.In this study,we aim to provide a summary on each of the popular and available nanoparticles in the market and list their optimum operational conditions.We classified nanoparticles into the three categories of metal oxide,organic and inorganic particles in this article.
