Determinação das energias de superfície do SnO2 puro e dopado Surface energy of pure and doped tin oxide

open access: yesCerâmica, 2009
A calorimetria tem se mostrado uma importante ferramenta para o controle e entendimento de comportamentos de sistemas nanoestruturados. Isto se deve basicamente às recentes medidas de energia de superfície reportadas na literatura; isto é, como em ...

Phase composition of Bi2O3 specimens doped with Ti, Zr and Hf [PDF]

open access: yesJournal of the Serbian Chemical Society, 2012
Powder mixtures of α-Bi2O3 containing 2, 5 and 10 mole % of TiO2, ZrO2 or HfO2 were homogenized, heated at 820ºC for 24 h and quenched in air. X-ray powder diffraction technique was used to characterize the prepared samples.

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling

open access: yesAdvanced Engineering Materials, EarlyView.
Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.

Comparative studies of the strength properties of germanum and silicon single crystals

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2022
In this paper, we present the results of microhardness tests performed by Vickers indentation of germanium and silicon single crystals. It’s shown that in the investigated samples there is a dependence of microhardness on the crystallographic directions ...

Effect of 3d-doping on the electronic structure of BaFe2As2 [PDF]

open access: yes, 2012
The electronic structure of BaFe2As2 doped with Co, Ni, and Cu has been studied by a variety of experimental and theoretical methods, but a clear picture of the dopant 3d states has not yet emerged.

Application of Raman and Photoluminescence Spectroscopy to MgO‐C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
Visible to near infrared luminescence of MgO is studied on MgO‐C bricks and nominally pure MgO powder, with focus on two similar sharp high‐intensity signals, at 699 and 871 nm, each surrounded by symmetrical sidebands. The nature of these sidebands is investigated by temperature‐dependent spectroscopic measurements, confirming phonon involvement by ...

Spin wave stiffness and exchange stiffness of doped permalloy via ab-initio calculation

open access: yes, 2019
The way doping affects the spin wave stiffness and the exchange stiffness of permalloy (Py) is investigated via ab-initio calculations, using the Korringa-Kohn-Rostoker (KKR) Green function formalism.
