Microstructure of near-infrared pulsed laser sintered titanium samples [PDF]

open access: yes, 2018
The microstructure and material properties of near-infrared pulsed laser sintered titanium have been investigated. Several analyses of the selectively laser sintered titanium powder, using characterisation techniques such as compressive strength ...

Thermodynamic and Kinetic Analysis of Cobaltite Oxidation Process [PDF]

open access: yesArchives of Metallurgy and Materials
In this paper results of the thermodynamic and kinetic analysis of cobaltite oxidation process were presented. Inductively coupled plasma atomic emission spectroscopy (ICP-AES) and energy dispersive X-ray fluorescence (ED-XRF) were used to determine the ...

Mössbauer and Ultrasonic Study of the As-Cast High-Entropy AlxCuCrCoNiFe Alloys [PDF]

open access: yes, 2017
Determination of the hyperfine-interaction parameters, acoustic and elastic properties of the high-entropy AlxCuCrCoNiFe alloys (HEAs) (x = 1, 1.8) in the as-cast state is carried out with the use of Mössbauer spectroscopy, x-ray diffractometry and high ...

Tin dioxide nanostructured thin films obtained through polymeric precursor method

open access: yesSemina: Ciências Exatas e Tecnológicas, 2012
Tin dioxide (SnO2) nanostructured thin films with low proportion of defects and low roughness were produced through the systematic control of temperature and viscosity of the precursor solutions used for thin films deposition.

Synthesis, Structure, and Dynamics of Tris(η5-cyclopentadienyl)lanthanides and Bis(η5-cyclopentadienyl)[bis(trimethylsilyl)amido]cerium(III) [PDF]

open access: yes, 2006
The crystal structures of tris(η5-cyclopentadienyl)lanthanides (Ln = Ce, Dy, Ho) have been determined using different X-ray diffraction methods. Cp3Ce and Cp3Ho (Cp = cyclopentadienyl) crystal data needed special solution and refinement methods, due to ...

Theoretical and material studies on thin-film electroluminescent devices [PDF]

open access: yes
The effect of surface nucleation processes on the quality of ZnS layers grown on (001) GaAs substrates by molecular beam epitaxy is reported. Reflection high energy electron diffraction indicated that nucleation at high temperatures produced more planar ...

Hydrogen adsorption and cohesive energy of single-walled carbon nanotubes [PDF]

open access: yes, 1999
Hydrogen adsorption on crystalline ropes of carbon single-walled nanotubes (SWNT) was found to exceed 8 wt.%, which is the highest capacity of any carbon material. Hydrogen is first adsorbed on the outer surfaces of the crystalline ropes.

A century of oil and gas exploration in Albania: assessment of Naturally Occurring Radioactive Materials (NORMs)

open access: yes, 2015
Because potential Naturally Occurring Radioactive Materials (NORMs) generated from oil and gas extractions in Albania have been disposed without regulatory criteria in many decades, an extensive survey in one of the most productive regions (Vlora-Elbasan)
