Konjac Bio-Molecules Assisted – Rod / Spherical shaped Lead Nano Powder Synthesized by Electrolytic Process and Its Characterization Studies

Abstract

Synthesis and structural characterization of Pb nanoparticles by electrolysis using a bioactive compound -konjac aqueous extract is the main aim of this study. This method is a unique, novel, low cost and double-step procedure with good reproducibility and has not been used for nanoparticles preparation so far. Konjac extract has been added to prevent the oxidation of Pb nanoparticles. Also the synthesized nanoparticles have been dried in open air to observe their stability. Various types of characterization tools like XRD, SEM, Particle Size Analyzer, TEM-EDS, DSC, AAS and FT-IR have been utilized to study characters of the end product. Anti-bacterial Studies has also been done. After completion of synthesis process that we have made an attempt to change the shape of the synthesized nanoparticles by the influence of sunbeams and to find the effects of the sunlight on nanomaterials.Amorphophallus campanulatus (Roxb.) Blume. ex Decne (Synonym : Amorphophallus paeoniifolius; Araceae) commonly known as Konjac is a tuberous, stout, indigenous herb, 1.0-1.5 m in height. The tubers contain an active enzyme amylase, amino acids, carbohydrates, saponin. Antioxidants are chemical substances that donate electron. The aqueous extract of A.campanulatus tuber has more significant antioxidant activity and more reducing power as compared to methanol extract [22]. 46.33 mg g -1 of flavonoidal content, 12.67 mg g -1 of phenolic contents and tannins are present in the air dried powder of A.campanulatus tubers [23].Konjac has listed as one of the top ten healthiest foods by World Health Organization (WHO). It is highly nutritious, with over 45% of Glucomannan, 9.7% of crude protein, 16 different kinds of amino acids up to 7.8%, 7 essential amino acids up to 2.5% , low fat and high in fiber. Glucose fructose and sucrose are also present in konjac. Glucomannan is a water-soluble dietary fiber and it is a polysaccharide (hemicelluloses) straight-chain polymer, with a small amount of branching. It is a high-molecular compound and a super absorbent; its size expands by 80-100xs after absorbing water. 30% to 40% of total production of flying powder is produced from konjac tuber. The Konjac flying powder is a polyol (natural polymer). It is used in precipitation of soluble heavy metal ions in wastewater.Lead nanostructures are attractive materials for its potential applications in lead batteries, catalysis, superconductor [24] and photonic crystal [25]. Earlier study reports that hexagon and flower shaped lead oxide (PbO 2 ) are the end product in electrolysis process (anodic oxidation of lead) using lead sheet as anode and distilled water (with very low ionic conductivity _ 6-10 µS/m and pH=6.5) as electrolyte [26].It is known that Pb nanoparticles are highly reactive and transfer electron to N 2 O, O 2 , etc. [27].

Effect of Certain Dietary Fibers on the Properties of Functional Yoghurt.

“…These changes differed from one treatment to another according to the type of used dietary fiber and it's addition ratio. Treatments made by adding konjac fiber gained the highest protein content either at zero time or during the storage period, when compared with the with the maltodextrin , These results agree with Theivasanthi and Alagar, (2012), who reported that Konjac fiber is highly nutritious , with over 45%of glucommans ,9.7% of crude protein , 16 different kinds of amino acid .…”

“…It is highly nutritious, with over 45% of glucomannan, 9.7% of crude protein, 16 different kinds of amino acids up to 7.8%, 7 essential amino acids up to 2.5% , low fat and high in fiber. Glucose fructose and sucrose are also present in konjac (Theivasanthi and Alagar, 2012). So, this work aims to study the effects of dietary fiber incorporation on the quality of plain yoghurt fermented with traditional yoghurt starter.…”

“…Typically, the sharper the graphite peak appears on a material XRD spectrum, the higher the crystallinity is [24]. However, the shape of the graphite peak is dependent on the copper element intensity.…”
