Synthesis of ?-Fe2 O3, Fe3 O4 and Copper Doped Fe3 O4 by sonochemical method

open access: yes, 2017
Nanoparticles of undoped and copper doped with Fe3 O4 of three concentrations (0.5, 1.0 and 1.5) are synthesized by sonochemical method. Structural, optical and morphological properties of these compounds were studied. Fe2+/Fe3+ ratio is found to be 2.36.

The optical absorption of gamma irradiated and heat-treated natural quartz

open access: yesMaterials Research, 2005
Quartz with aluminum as impurity absorbs energy from ionizing radiation and modifies its color. Colorless quartz becomes smoky or dark smoky (morion quartz) when exposed to gamma rays.

On the electronic structure of Cu (III) and Ni (III) in La2 Li½ Cu½ O4, Nd2 Li½ Ni½ O4, and Cs2 KCuF6

open access: yes, 1997
The electronic structure of copper and nickel in the oxidation state +III was studied for La2 Li½ Cu½ O4 , Cs2 KCuF6 , and Nd2 Li½ Ni½ O4 by X-ray absorption near-edge structure (XANES) spectroscopy at the L2,3 -thresholds of Cu and Ni as well as the K-

Solid state solubility between SnO2 and (FeSb)O4 at high temperature

open access: yes, 2006
The solubility in the solid state was investigated for the pseudo-binary system SnO2—(FeSb)O4 at high temperature. Stoichiometric amounts of pure SnO2 and (FeSb)O4 powders were mixed and reacted in air at 1373 K.

Nickel-fe3 o4 magnetic nanoparticles supported on multiwalled carbon nanotubes: Effective catalyst in suzuki cross coupling reactions

open access: yes, 2021
Nickel-Fe3 O4 nanoparticles supported on multi-walled carbon nanotubes (Ni-Fe3 O4 /MW-CNTs) were synthesized by mechanical grinding of a sample of nickel salt, Fe3 O4 and MWCNTs using a ball-mill mixer.

Studies on the repair and conformation of DNA containing O6-alkylguanine and O4-alkylthymine [PDF]

open access: yes, 1992
The carcinogenic N-nitroso compounds alkylate DNA. Among the different products of alkylation, O6-alkylguanine and O4-alkylthymine have attracted most of the attention since they are highly mutagenic and a correlation exists between their formation and ...
