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…

Comparison of different sintering methods of Pb 1-x Cr x Te thermoelectric nanocomposites doped with iodine

Aleksandra Królicka, Monika Michalska

Abstract
N-type PbTe polycrystals were fabricated by the Bridgman method. Subsequently, the materials were pulverized in a planetary ball mill for 15 hours, pressed and sintered. In this paper we compare two…

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
