Thermally assisted magnetic separation and characterization studies of a low-grade hematite ore

Dash, Nilima; Rath, Swagat S.; Angadi, Shivakumar, I (Powder Technology, 346, 2019: 70-77)

Alternative beneficiation strategies are now being adopted to upgrade the iron values in low-grade iron ores that do not respond to physical beneficiation owing to their complex texture and poor liberation pattern. Thermal ...
Electrochemical glucose sensing characteristics of two-dimensional faceted and non-faceted CuO nanoribbons

Sahoo, Rakesh K.; Das, Arya; Samantaray, Koyel; Singh, Saroj K.; Mane, Rajaram S.; Shin, Heon-Cheol; Yun, Je Moon; Kim, Kwang Ho (Crystengcomm, 21(10), 2019: 1607-1616)

We present faceted and non-faceted crystal cupric oxide (CuO) nanoribbons synthesized by different processes for glucose-sensing applications. The faceted and non-faceted CuO nanoribbons are grown via hydrothermal and ...
Effect of heat treatment on microstructure and mechanical properties of 316L steel synthesized by selective laser melting

Salman, O. O.; Gammer, C.; Chaubey, A. K.; Eckert, J.; Scudino, S. (Materials Science And Engineering A-Structural Materials Properties Microstructure And Processing, 748, 2019: 205-212)

The influence of annealing at different temperatures (573, 873, 1273, 1373 and 1673 K) on the stability of phases, composition and microstructure of 316L stainless steel fabricated by SLM has been investigated and the ...
Biosorption of dysprosium (III) using raw and surface-modified bark powder of Mangifera indica: isotherm, kinetic and thermodynamic studies

Devi, Aparna Prabha; Mishra, Pravat Manjari (Environmental Science And Pollution Research, 26(7), 2019: 6545-6556)

In this paper, we have used HDTMA-Br- and NaOH-treated bark powder of Mangifera indica as bio-sorbents for the removal of dysprosium (III) from its aqueous solution. The adsorption process was investigated at different ...
Leaching of Rare Earth Metals from Phosphor Coating of Waste Fluorescent Lamps

Anand, Amit; Singh, Randhir; Sheik, Abdul Rauf; Ghosh, Malay Kumar; Sanjay, Kali (Transactions Of The Indian Institute Of Metals, 72(3), 2019: 623-634)

Phosphors made from compounds of rare earth metals (REMs) are very efficient. This material needs to be recycled for recovery of REMs after the fluorescent lamps (FLs) reach end of life. This work focuses on the leaching ...
Nanosilver Coated Coir Based Dielectric Materials with High K and Low Df for Embedded Capacitors and Insulating Material Applications-A Greener Approach

Rout, Sanjay K.; Anwar, Shahid; Tripathy, Bankim C. (ACS Sustainable Chemistry & Engineering, 7(4), 2019: 3824-3837)

In this work, the dielectric properties of lignocellulosic coirs coated with silver nanoparticles were studied. Nanosilver coating increased the dielectric constant (K) value and decreased the dissipation factor (Df). The ...
Tungsten carbide - Titanium carbide composite preparation by arc plasma melting and its characterization

Dash, Tapan; Nayak, Bijan Bihari (Ceramics International, 45(4), 2019: 4771-4780)

WC-TiC composite with six different values of TiC in the range 1-15 wt% was prepared by arc plasma (Ar) melting. Characterizations of the in situ melt-cast composite as well as its powder by XRD, FESM, TEM, SAED and EDS ...
Magnetoelectric coupling of manganese ferrite-potassium niobate lead-free composite ceramics synthesized by solid state reaction method

Komalavalli, P.; Banu, I. B. Shameem; Anwar, Shahid (Journal Of Materials Science-Materials In Electronics, 30(4), 2019: 3411-3417)

Lead-free composite ceramics xMnFe(2)O(4)-(1-x) KNbO3 with the composition of x=0.20, 0.30 and 0.40 were synthesized by the solid state reaction method to obtain the composites of ferrite and ferroelectric to achieve ...
Sodium fluoride assisted acid leaching of coal fly ash for the extraction of alumina

Tripathy, A. K.; Behera, B.; Aishvarya, V.; Sheik, A. R.; Dash, B.; Sarangi, C. K.; Tripathy, B. C.; Sanjay, K.; Bhattacharya, I. N. (Minerals Engineering, 131, 2019: 140-145)

Coal fly ash, generated in thermal power plants was processed through sulphuric acid leaching for the extraction of alumina. Both fly ash and alkali treated fly ash residue, obtained after partial removal of silica, were ...
Praseodymium promotes B-Z transition in self-assembled DNA nanostructures

Bhanjadeo, Madhabi M.; Subudhi, Umakanta (RSC Advances, 9(8), 2019: 4616-4620)

Millimolar concentrations of PrCl3 can induce sequence-specific B-Z transition in various-self-assembled branched DNA (bDNA) nanostructures. Competitive dye binding and thermal kinetics suggest that the phosphate backbone ...
