“…Figure 4(a) reveals XRD peak values at 42 ∘ and 49 ∘ , which are associated with the (111) and (200) planes of orientation, respectively. These values correspond well to the typical diffraction patterns observed for face-centered cubic (fcc) Ni nanoparticles [27,28]. Similar results have been reported by Harish and coworker during the formation of nickel hydroxide nanoparticles [29].…”

Dendrimers have emerged as one of the most promising, cost-effective synthesizing methodologies in which highly monodispersed metallic nanoparticles can be produced with varied chemical functionalities. In this report, we have investigated the synthesis and application of as-synthesized dendrimer-encapsulated zero-valent nickel "Ni(0)" nanoparticles (NPs), using a fourth generation (G4) NH 2 -terminated poly(amido)amine (PAMAM) dendrimer as the host template, as potential antimicrobial agents. Apparently, based on ultraviolet visible spectroscopy (UV-vis) and transmission electron microscopy (TEM) analyses, Ni(0) NPs with an average measured size less than 10 nm in diameter were formed within the interior void cavity of the dendrimer structure. X-ray diffraction (XRD) analysis indicates that the NPs exhibited a single-phased, face-centered-cubic (fcc) crystallographic structure. Furthermore, to evaluate the antimicrobial activity of the dendrimer-encapsulated Ni(0) NPs, disk diffusion assay and minimum inhibitory concentration (MIC) examinations, both antimicrobial tests, were conducted. Subsequently, UV-vis analyses, after exposure of the dendrimer-encapsulated Ni(0) NPs to both Gram-negative and Gram-positive bacteria, revealed that the dendrimer-encapsulated particles prevented the growth of bacteria during the culturing stage.

“…On the other hand, reduced droplet size can be achieved either by using an electrospray which is capable of producing directly nanoscale monodispersed particles or by the modification of atomizing techniques, like filter expansion aerosol generator (FEAG) assisted spray pyrolysis (FEAG-SP) [35]. The low-pressure condition was applied in spray pyrolysis as an attempt to control the environment of the surrounding processes as reported by Wang et al [36], in the investigation of low pressure-SP (LPSP). Furthermore, the development of SP method was based on the diversity of thermal energy behavior as a heat source such as flame-SP (FSP) [37] and pulse combustion SP [38].…”

Abstract. Nanotechnology today is regarded as a revolutionary technology that can help to address the key needs related to energy, environment, health and agriculture in developing countries. This paper is a short review on the development and challenges of nanotechnology in Indonesia. Nanotechnology offers great potential benefits, there is emerging concerns arising from its novel physicochemical properties. The main applications of nanotechnology in the different sectors which is vital and its economic impact in Indonesia is also discussed. The achievment and development of nanotechnology including synthesis and dispersion of nanoparticles (NPs) and its applications in various fields is briefly addressed in Nanotehcnology and Graphene Research Center, Universitas Padjadjaran (Unpad). Despite significant progress in developmental goals, many challenges in the development of nanotechnology proccesing need to be resolved such as support infrastructure and evolution of new form of collaborative arrangements between various sectors and policies which is emerged as an important factor enabling development.

“…Generally, a onedroplet-to-one-product particle (ODOP) conversion is considered the typical particle formation mechanism in conventional spray pyrolysis (CSP). In this project, various modified spray pyrolysis methods were developed and introduced for nanoparticle synthesis, including salt-assisted spray pyrolysis (SASP) [9][10][11][12] and low pressure spray pyrolysis (LPSP) [13][14][15][16][17][18] as well as flame-assisted spray pyrolysis (FASP). [19][20] Salt-assisted spray pyrolysis (SASP) is a modified spray pyrolysis method that introduces salts into the precursor solution.…”

“…Low-pressure spray pyrolysis (LPSP) was applied to the proper nanoparticle synthesis as well. [13][14][15][16] The distinguishing feature of this process is a dramatically different particle formation mechanism. It is expected that a micron-sized droplet will first undergo rapid solvent evaporation upon entering the low-pressure environment.…”

“…This indicates that the mechanism of particle formation in the LPSP process is obviously complex, including not only process parameters, but also the physicochemical proper ties of the precursor. Various kinds of materials, from single oxide to multicomponent materials, i.e., nickel, 13) nickel oxide, 13) titanium oxide, 14) barium titanate, [15][16] indium tin oxide, 17) and a doped phosphor material (Y2O3:Eu 3 ), have been prepared successfully via the LPSP method.…”
