Use of the cold substrate method for biomaterials: the dtructural and biological properties of the Ag layers deposited on Ti-6Al-4V
(Springer, 2020)
Silver nanofilms were vacuum-deposited on Ti-6Al-4V substrates at low (< 300 K) temperatures to improve their biocompatibility. After the surface of the Ti-6Al-4V samples was coated with Ag over the temperature range from ...
Assessment of rheological and sedimentation characteristics of fresh cemented tailings backfill slurry
(Taylor & Francis Ltd, 2020)
Unreasonable choice of solid content (SC) and cement-to-tailings ratio (c/t), including pipeline networking system, will lead to some pipeline problems, such as blockage, wear, and rupture. Hence, this study deals with the ...
Tracking the birth and growth of Cimmeria: Geochronology and origins of intrusive rocks from NW Iran
(Elsevier, 2020)
New geochronological and geochemical data for Late Neoproterozoic to Mesozoic intrusive rocks from NW Iran define major regional magmatic episodes and track the birth and growth of one of the Cimmerian microcontinents: the ...
Efects of Covid‑19 outbreak on environment and renewable energy sector
(Springer, 2020)
Many articles have been written in the medical feld related to the Covid-19 outbreak that has surrounded the World and killed many people. However, its environmental and energy impacts have not been sufciently studied. ...
The Paleogene ophiolite conundrum of the Iran-Iraq border region
(Geological Soc Publ House, 2020)
New and compiled geochemical, isotopic and geochronological data allow us to propose a new explanation for Paleogene oceanic magmatic rocks along the Iran-Iraq border. These rocks are represented by a thick pile (>1000 m) ...
On the tse of nanofluids in solar energy applications
(Springer, 2020)
Renewable energy technologies are in the centre of interest to narrow the gap between fossil fuels and clean energy systems. the dominant role of solar energy systems among the alternatives is beyond question owing to being ...
Effect of different abutment materials on stress distribution in peripheral bone and dental implant system
(Yildiz Technical Univ, 2020)
In this study, the effect of different abutment materials on the stress distribution in bone tissue around the dental implant was investigated using ANSYS packet program based on finite element method. the study aims to ...
Optical and electrical properties of refined carbon derived from industrial tea waste
(Iop Publishing Ltd, 2020)
The utilization of nano- and well-ordered carbon materials such as graphene especially in carbon-based electrical devices and in energy storage areas is becoming important in terms of developing economical methods and ...
Investigation of the electrical properties of Ag/n-Si schottky diode obtained by two different methods
(Korean Assoc Crystal Growth, Inc, 2020)
In present study, Ag/n-Si Schottky diodes were produced by vacuum evaporation method at two different substrate temperatures (200 K and 300 K) and structural, optical, electrical properties were investigated. X-ray diffraction ...
