Thermal stability of nanostructured TiZrSiN thin films subjected to helium ion irradiation
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2015)
The phase stability, upon vacuum annealing up to 1000 degrees C, of nanostructured (Ti,Zr)(1-x)SixN thin films is investigated by X-ray diffraction analysis as a function of Si content (0.13 LT = x LT = 0.25) and prior ...
Thermal stability of nanocrystalline (Ti,Zr)(0.54)Al0.46N films implanted by He+ ions
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2015)
The influence of irradiation with He+ ions on the thermal stability of TiZrN and (Ti,Zr)(0.54)Al0.46N nanocrystalline films was studied. The TiZrN and (Ti,Zr)(0.54)Al0.46N films were prepared by reactive magnetron sputtering. ...
Experimental evidence of the superfocusing effect for axially channeled MeV protons
(Physical Review B: Condensed Matter and Materials Physics, 2016)
Sub-Angstrom focusing of megaelectronvolt (MeV) ions within axial channels was predicted over 10 years ago, but evidence proved elusive. We present experimental angular distributions of axially channeled MeV protons in a ...
Pomegranate (Punica granatum): a natural source for the development of therapeutic compositions of food supplements with anticancer activities based on electron acceptor molecular characteristics
(Functional Foods in Health and Disease, 2016)
Background: Numerous in vitro and in vivo studies, in addition to clinical data, demonstrate that pomegranate juice can prevent or slow-down the progression of some types of cancers. Despite the well-documented effect of ...
The donut and dynamic polarization effects in proton channeling through carbon nanotubes
(New Journal of Physics, 2010)
We investigate the angular and spatial distributions of protons with an energy of 0.223 MeV after channeling them through an (11, 9) single-wall carbon nanotube of 0.2 mu m length. The proton incident angle is varied between ...
The impact of autophagy on cell death modalities in CRL-5876 lung adenocarcinoma cells after their exposure to gamma-rays and/or erlotinib
(Cell Biology and Toxicology, 2016)
In most patients with lung cancer radiation treatment is used either as single agent or in combination with radiosensitizing drugs. However, the mechanisms underlying combined therapy and its impact on different modes of ...
Zero-degree focusing of channeled ions and crystal rainbows
(Physics Letters A, 2001)
We analyze here theoretically the connection between the effect of zero-degree focusing of channeled ions and the crystal rainbow effect. The calculations were performed for Ne10+ ions and a LT 100 GT Si thin crystal. The ...
Response of a radioresistant human melanoma cell line along the proton spread-out Bragg peak
(International Journal of Radiation Biology, 2010)
Purpose: To analyse changes of cell inactivation and proliferation under therapeutic irradiation conditions along the proton spread out Bragg peak (SOBP) with particular emphasis on its distal declining edge. Materials and ...
Study of MW-scale biogas-fed SOFC-WGS-TSA-PEMFC hybrid power technology as distributed energy system: Thermodynamic, exergetic and thermo-economic evaluation
(International Journal of Hydrogen Energy, 2021)
Advanced biogas power generation technology has been attracting attentions, which contributes to the waste disposal and the mitigation of greenhouse gas emissions. This work proposes and models a novel biogas-fed hybrid ...
Mechanochemical Synthesis and Thermal Dehydrogenation of Novel Calcium-Containing Bimetallic Amidoboranes
(ACS Sustainable Chemistry and Engineering, 2021)
Metallic amidoboranes are widely investigated candidates for solid-state hydrogen storage, and much focus shifted recently toward bimetallic amidoboranes. Bimetallic amidoboranes are expected to introduce novel and enhanced ...
