Synthesis of Super Water Absorbent Prepared by .GAMMA.-Irradiation from Natto String.

Water radiolysis by gamma –irradiation for high quality synthesis of Nickel Oxide nano sheet

A simple, time effective and cost effective, methos was reported for synthesis of nickel oxide nanostructure. The NiO nanostructure was synthesized by gamma-irradiation method from NiSO4 precursor. The solution was irradiated by 60Co gamma-ray source at the dose rate of 40 Gy/min for determined time. The synthesized powders are characterized by means of X-ray powder diffraction (XRD), Energy-di...

Simulation of gamma irradiation system for a ballast water treatment

  ABSTRACT Background: Invasion  by  different  kinds  of  ballast  water  microorganisms  is  one  of  the  most important  marine  environment  problems  around  the  world therefore  preventing the  invasion  of  these  unwanted  and  harmful  stowaways  is  one  of  the  main strategies  of  responsible  agencies.  Some  of  these  methods  such  as  ocean excha...

Synthesis of carboxymethylcellulose/starch superabsorbent hydrogels by gamma-irradiation

BACKGROUND Superabsorbent hydrogels show a large potential in a wide array of applications due to their unique properties. Carboxymethylcellulose (CMC) is a commercially available water-soluble cellulose derivative of major interest in the hydrogel synthesis. High-energy irradiation allows the chemical crosslinking without the use of crosslinking agents, while the introduction of other natural ...

"Nanofiltration" Enabled by Super-Absorbent Polymer Beads for Concentrating Microorganisms in Water Samples.

Detection and quantification of pathogens in water is critical for the protection of human health and for drinking water safety and security. When the pathogen concentrations are low, large sample volumes (several liters) are needed to achieve reliable quantitative results. However, most microbial identification methods utilize relatively small sample volumes. As a consequence, a concentration ...
