Synthesis and characterization of nanocrystalline tin sulfide (SnS) with SnO2 nanoislands flakes

Monika Michalska, Mariusz Andrzejczuk, Krzysztof Oberda

Abstract:

In this paper, we present the results of an investigation of the compositional and structural features of nanocrystalline tin sulfide (SnS) decorated with SnO2, which was synthesized in a high-energy ball-milled (HEBM) process. Tin and sulfur powders were used as starting reagents. The materials were turned into nanopowders after the heating (followed by HEBM) that was carried out in nitrogen…

New synthesis route to decorate Li4Ti5O12 grains with GO flakes

Monika Michalska, Dominika A Ziółkowska, Mariusz Andrzejczuk, Agnieszka Krawczyńska, Agata Roguska, Andrzej Sikora

Abstract:

Lithium titanium oxide (Li4Ti5O12) particles were surface-decorated with 1–5% wt. of graphene oxide (GO) using new low temperature method (LTM). All the synthesized materials have been characterized by a number of methods: X-ray powder diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), scanning…

Formation of Fe and Ni substituted LiMn2–XMXO4 nanopowders and their crystal and electronic structure and magnetic properties

E. Talik, L. Lipińska, A. Guzik, P. Zajdel, M. Michalska, M. Szubka, M. Kądziołka-Gaweł, R. L. Paul

Abstract:

The Pechini sol-gel method was applied to obtain LiMn2–xTxO4 (T = Ni, Fe; x = 0.1 to 0.5) nanopowders. Crystal and electronic structures, chemical composition and magnetic properties of the materials were characterized by X-ray diffraction, XPS, SEM/EDX microscopy, prompt gamma-ray activation analysis…

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu

Dr. András Paszternák, founder of Nanopaprika
