“…al, (2016) [23] have synthesized pure particles by calcinating it at 200 also discussed the appearance of various phases of iron oxide at various calcination temperatures. However, by a combined heating method of iron oxide powder at Ray Analysis EDX was performed for the synthesized -Fe2O3 nanoparticles and elemental composition of the sample (Figure3) showed the presence of iron, carbon and oxygen and no other impurities were found [21].…”

The current study deals with analysis of shear thinning and viscoelastic behaviour of cellulose fluid carrying iron oxide particles for injectable in-situ hyperthermia treatment. The iron oxide nano-particles of size 106 nm used in the study were synthesized through co-precipitation method using hydrothermal technique and were found to show high coercivity value of 75.83 Oe indicating its good stability. The magnetic nano-particles were suspended in a cellulose fluid for better injectability. This suspension along with the iron-oxide magnetic particles showed good heating efficiency of about 43 0 C in 60 seconds making it ideal for hyperthermia treatment. The specific absorption rate (SAR) and effective specific absorption rate (ESAR) were calculated for the as synthesized nano-particles and for suspension at varying concentrations and it was found that an optimized concentration of 20 mg of the nano-particles dispersed in 5 ml of the polymeric solution was ideal for hyperthermia treatment. The rheological properties studied for the suspension showed that the fluid showed shear-thinning and viscoelastic properties similar to that of human blood making it more suitable for carrying the iron-oxide nano-particles to the tumour site irrespective of the kind of shear stress that it is subjected to. The synthesized particles and the suspension fluid could successfully induce mild heat to the tumour site when delivered through intra-venous route or through intramuscular route thereby aiding radiotherapy and chemotherapy by dilating the blood vessels and thus enabling blood circulation to the poorly oxygenated cancer cells.

“…840-311 along with polypyrrole characteristics peak at diffraction angle (25.8 ). [34] Fe 2 O 3 appearance into the polypyrrole system may be due to partial oxidation of ferric chloride hexahydrate oxidant. At short polymerization time, reaction does not take place completely and left out ferric ions may oxidize to Fe 2 O 3 during washing process.…”

A facile and eco‐friendly synthesis of polypyrrole from monomer pyrrole using nominal amount of ferric chloride hexahydrate (FeCl3.6H2O) oxidant in aqueous solution by chemically oxidative polymerization method has been reported. The use of aqueous solvent and ferric chloride hexahydrate salt in polypyrrole synthesis have an eco‐friendly route favorable for the production of polypyrrole in large quantities. The synthesized polypyrrole samples exhibit good electrical conductivity (2 S/cm) and yield of 80% for reaction time of 8 hr at 5°C. Quality and properties of polypyrrole samples have been thoroughly investigated with varying reaction time and temperature while other synthesis parameters like molar ratio of oxidant to monomer, oxidant concentration, and solvent were kept constant. X‐ray diffraction analysis of polypyrrole with a shorter reaction time shows the presence of iron oxide (Fe2O3) peaks. The complete reaction may not occur at shorter reaction times due to which residual ferric ions converted into Fe2O3. X‐ray photoelectron spectroscopy measurement of polypyrrole also confirms the formation of Fe2O3. Appropriate selection of reaction time and temperature produced pure phase polypyrrole with high yield and good conductivity. Synthesized polypyrrole by our eco‐friendly and cost‐effective technique exhibits prominent electromagnetic shielding effectiveness value of 30 dB in the X‐band (8–12 GHz).

The steel industries generate a high volume of solid waste each year. The disposal of solid waste is a Hercules task for steel industry management. The solid waste contains heavy metals like iron, chromium, lead, zinc and toxic chemical compounds. The solid waste disposal contributes for ground water pollution and soil pollution. The steel industry solid waste contains a high percentage of iron oxide more than 12%. The aim of this project is to convert steel industry solid waste into a red oxide primer. The solid waste samples are collected from a local steel industry. The samples are crushed and passed through a 53 micron mesh to get fine powder. The powder is mixed with Long oil alkyd, calcium carbonate and Butanol. The mixture mixed intensively by the help of a wet grinder until it gets adhering properties and become as a primer. The adhesive properties of the primer is tested by painting on a metal surface and after drying the primer on the metal surface and tested by the peeling method to check the strength of the primer. The primer viscosity modified by adding turpentine oil. The red oxide primer used as a dielectric or pre-coating on iron structure. It was observed that the red oxide produced by using steel industry solid waste is at par with commercially available red-oxide primer. The red oxide primer production from the steel industry sludge is technically feasible and economically viable.
