“…Nanotechnology is defined as the specialization of materials at atomic, molecular, and supramolecular sizes. A more specific definition of nanotechnology is given by the American Association of Nanotechnology, according to which nanotechnology is the specialization of materials with a minimum size of 1-100 nanometers (1 billion nanometers is equal to 1 m) [4][5][6]. Nanotechnology is one of the most important tools in modern agricultural architecture.…”

The Vietnam’s agricultural sector had to challenge with its course and learned lessons of further development. Novel policy might be adopted to encourage the private investments and sectors in agriculture. Furthermore, an introduction of new models such as climate-smart or green agriculture and application of modern technology increased productivity at the same time and creating jobs for millions of agricultural workers and reversing the massive rural-urban migration flux. Vietnam’s agricultural sector needs to maintain the reform momentum, particularly liberalization policy, and to boost up agricultural potential. Obstacles such as land limitation policy must be removed to enable large-scale production and encourage private investment in the agricultural sector. To avoid being trapped by its own success, Vietnam is now shifting the old development paradigm that focuses too much on the quantity to the quality of the agricultural production. The government makes major efforts to achieve at the same time agricultural growth, better livelihood of the farmer, and the development of the rural areas. However, Vietnam still needs to prepare a “transition strategy” to overcome the impact of the technological progress on the traditional agricultural workers.

Poly (3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) has attracted much attention on applications of neural interfaces and other biomedical fields due to its excellent electrical performances and good biocompatibility. However, its stability still remains challenge. Here, a conductive polymer hydrogel (CPH) made from PEDOT:PSS is modified on platinum (Pt) substrate successfully through electrochemical gelation, employing copper (Cu) as the sacrificial layer. The as-prepared CPH electrode provides extensive large surface area with good adhesion after dried in the air. The uniform flower-like structure helps the electrode achieve a significantly low square impedance down to 10.09 Ω cm 2 (reduction of 54.89%) at 1 kHz, compared with that of bare Pt. It exhibits a high cathodic charge storage capacity (CSC c ) up to 82.36 mC cm À2 , about 27 and 16.18 times higher than that of bare Pt and PEDOT:PSS coating respectively. Besides, no obviously variation of CSC c occurs after 5 CV cycles in phosphate buffered saline (PBS), and superior charge injection capacity (CIC) was also observed. Such CPH material presents great potential for preparing functionalized flexible electrode, implying promising applications on neural implants and other flexible electronics.

This work studies the impact of positioning nickel nanoparticles (Ni-NPs) on the surface of doped (P84-PEO) nanocomposite films by using an ultrauniform magnetic field as a model for positioning magnetic NPs inside a polymeric matrix. This process is used to achieve desired and adjustable optoelectronic properties and to obtain new optical and electrical characteristics.P84-PEO copolymer doped with Ni-NPs exposed to a 450 mT magnetic field during the preparation give rise to a momentous increase in surface roughness, surface reactivity, and modified optical parameters, besides forming Ni oxides on the surface. Based on X-ray photoelectron spectroscopy experiments, substantial extra shifts occurred in the binding energies of photo-excited electrons from the O1s and C1s core levels. Additionally, the deconvoluted O1s spectra displays an additional photoelectron peak at 530.0 eV, most likely attributed to oxidized Ni-NPs at the surface. Moreover, optical and structural properties were studied using UV-Vis and PL spectroscopy and X-ray diffraction.
