The CO2 corrosion behavior of sensitized and non-sensitized 304 and 316 stainless steels in the absence and presence of H2S was investigated using cyclic polarization and electrochemical impedance spectroscopy techniques. The sensitization resulted in significant negative shift on pitting potential for both alloys. The general CO2 corrosion rate of...

A non-enzymatic glucose sensor based on a pencil graphite electrode (PGE), a modifier suspension including the conducting polymer poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and CuO nanoparticles was developed. Then it was subjected to cyclic voltammetry and chronoamperometry to evaluate the electrochemical performance of th...

Hybrid organic-inorganic halide perovskite (CH3NH3PbI3) materials have broad applications such as photovoltaics, light emitting diodes, and sensors. However, one of the major drawbacks of these materials is their sensitivity to moisture. Here, a new promising perovskite nanocrystal: tetramethylammonium lead triiodide (CH3)4NPbI3 has been introduced...

Although dental ceramic restorations are biocompatible, they are not necessarily bioactive. They can be modified by bioactive glasses to exhibit bioactive behavior well adapted to the surrounded tissue. Such modification can be done using mixtures of dental ceramic/sol–gel-derived bioactive glass expected to prolong the life time of the fixed denta...

This paper presents a new method to produce a familiar compound, Methylammonium Lead Iodide. This method includes two steps, vapor deposition of Lead Iodide on a substrate following by dipping it in Methylammonium iodide solution. Former methods involve spin coating of lead iodide on a substrate. Using evaporation technique, produced film is nano-s...

In this paper, the synthesis of Aluminum Nitride-Silicon Carbide composites through a combustion reaction among aluminum, silicon nitride (as the solid source of nitrogen) and carbon powders was investigated by Xray diffraction and scanning electron microscopy. The combustion reaction was initiated through the ignition of the powder mixture by micr...

Hexavalent chromium ion is the most toxic form of chromium ions and it is considered as a hazardous pollutant. So removing this ion from effluents is very important. One possible approach is reducing Cr(VI) to Cr(III) by metallic iron. Sponge iron was used in this study, and the influence of parameters such as the amount of sponge iron in the solut...

The use of bone glue has become increasing frequent due to its advantages and conveniences. Poly Methyl Methacrylate (PMMA) has been used for a long time as bone cements and bone glues, but it is not the best option due to its biocompatibility. Therefore, different kinds of composites have been invented. Hydroxyapatite (HA), which is a main ingredi...

Due to rather weak environmental performance of stainless steel 316L, a plasma electrolytic nitro/carburizing (PEN/C) process including hydroxy-apatite particles were performed on pins made of stainless steel 316L. In order to compare, three groups of pins were prepared: the first was untreated stainless steel 316L pins, the second group was stainl...

... The magnitude of the corrosion rate can be reflected by the corrosion current density (i corr ) and the corrosion potential (E corr ). The two parameters (i corr and E corr ) can be extrapolated by Tafel extrapolation, and they were compared with those of several austenitic stainless steels, such as 316 and 316L stainless steels, for different processes and conditions, or their modified stainless steels in the existing research, as shown in Figure 6c [1,[41][42][43][44][45]. The comparison showed that the stainless steel designed in this work had a lower value of i corr and a higher value of E corr , indicating better electrochemical performance. ...
... To validate this concept, cuprous oxide, a representative semiconductive 2D oxide used in glucose sensors owing to its strong catalytic activity, stable structure, and non-toxicity [21,22] , is selected as the electrochemically active material herein to construct a non-enzyme-based glucose sensor. The thermodynamically favorable galvanic reaction between metallic Ga and Cu ions facilitates the direct growth of Cu-based compounds on the Ga-LM surface [23][24][25] . ...
... 10 Cubic structured (CH 3 ) 4 NPbI 3 was modeled with an initial lattice parameter of 5.47 Å. In comparison, both tetragonal and hexagonal structures were modeled with initial lattice parameters a = 6.43 Å, c = 4.60 Å, and a = 9.77 Å and c = 7.91 Å, respectively, from the experimental study of ref. 23 The cutoff for the wave function of cubic, tetragonal and hexagonal structures was converged to 60 Ry, the Monkorst-Pack k point grid, and the lattice parameter convergence was also achieved for the three structures within the 1 mRy per atom convergence criteria. The Murnaghan equation of state 32 curve fitting was carried out to determine the optimized lattice parameters. ...
... The dried products were pulverized in an agate mortar with a pestle and passed through a granulometric sieve (Tyler 325 mesh -ASTM 325), which corresponds to an aperture of 45 micrometers (ISO 3310/1) so that only particles smaller than that size could be selected. 21,33 Experimental infiltrant formulation Experimental infiltrants were made in a dark room with yellow light and controlled temperature (25ºC), based on previous studies. 10 The resin blends were made with a magnetic stirrer mixing 75 wt% triethylene-glycol-dimethacrylate (TEGDMA), 25 wt% ethoxy bisphenol A glycidyl dimethacrylate (BisEMA), 0.5 wt% camphoroquinone (CQ), and 1 wt% ethyl 4-dimethylaminebenzoate (EDAB) for 24 h to ensure homogeneity. ...
... Graphene nanoplatelets (Gnp) are only one atom thick and thus have attracted interest in the field of materials science and condensed matter physics [18][19][20]. It is a twodimensional (2D) sheet of sp 2 -bonded carbon arranged in a honeycomb lattice and is the building block of carbon allotropes like zero-dimensional (0D) fullerenes, onedimensional (1D) carbon nanotubes (CNTs), and threedimensional (3D) graphite [21,22]. ...
... 55 In a study on the removal of the chromate ion from aqueous solutions, two different DRIs, which had a surface area of 0.769 and 0.924 m 2 /g, were used successfully as catalysts. 56 A study on the effect of adding biomass to iron ore pellets before burning which was subsequently reduced by hydrogen showed that the addition of 2% of biomass causes the surface area of the obtained DRI to increase from 6.03 m 2 /g without addition to 16.26 m 2 /g after the addition, and the presence of iron whiskers in the DRI was noticed. 57 Thus, it is clear that the large surface area obtained in the present work is due to the formation of iron whiskers during the reduction process. ...
