Up to now, researchers have proposed several synthesis methods for the preparation of β-nickel(II) hydroxide nanostructures. Most of these approaches contain harsh synthetic conditions such as multi-step processes, high temperatures and long reaction time. In this work, a novel, facile and low cost method is introduced to produce of β-Ni(OH)2 nanostructures using the gas-solution precipitation ...

In this investigation a simplified arc discharge apparatus was used to synthesize mullti-wall carbon nanotubes. Because of not requiring vacuum equipment, heat exchange system, active or inert gases, this method is found to be cheaper and simpler than traditional arc discharge in gas environment. Using this method, CNTs are produced by performing an arc discharge between two graphite electrodes...

The synthesis of singleand double-wall carbon nanotubes by gas flow-modified, catalyst-supported chemical vapor deposition (CCVD) is reported. We have investigated the gas flow condition dependence on the synthesis of carbon nanotubes (CNTs) by placing blocks in the CCVD reactor. Carbon nanotubes having large diameters are preferentially grown under turbulent flow conditions. This indicates tha...

In many scenarios we need to find the most likely program under a local context, where the local context can be an incomplete program, a partial specification, natural language description, etc. We call such problem program estimation. In this paper we propose an abstract framework, learning to synthesis, or L2S in short, to address this problem. L2S combines four tools to achieve this: syntax ...

Combustion of corn leaf as a model biomass from agricultural waste is simple way to obtain the energy. It produces low-value by-product ash and rich in silica that can become precursor for zeolite production. In this study, acid-treated leaves combustion was performed produce high purity (SiO2). The diffraction pattern suggested extracted amorphous without impurities phase. Additionally, nitrog...

Objectives: Synthesis of hybrid nanoparticles (NPs) and intercalation as prepared NPs inside polymer matrix to fabricate nanocomposites (NC) evaluate the optoelectronic properties. Method: A simple, time consuming solution combustion method was used synthesize silver doped gallium oxide (AgGaO2) NPs. The casting process employed prepare NC films poly(vinyl alcohol) (PVA) with inclusion AgGaO2 n...

LaNiO3 and LaCoO3 perovskites synthesized by self-combustion were characterised studied in the ammonia decomposition reaction for obtaining hydrogen. Both fuel to metal nitrates molar ratio calcination temperature found be crucial synthesize self-combustion. Moreover, generating non-precursor species during synthesis small size two factors which significantly influenced catalytic activity. Henc...

Extracting fine patterns on real surfaces is a difficult problem. We present a solution to extract such patterns on specular surfaces, and to synthesize similar patterns as bump maps.
