Abstract:

Molybdenum dioxide (MoO2) is known for its catalytic activity toward reforming hydrocarbons. The objective of this study was to evaluate the effect of biofield energy treatment on physical, thermal, and structural properties in MoO2. The MoO2 powder sample was divided into two parts, one part was remained as untreated, called as control, while the other part was subjected to Mr. Trivedi’s biofield energy treatment and called as treated. Both control and treated samples were investigated using X-ray diffraction (XRD), thermogravimetric analysis (TGA), and Fourier transform infrared (FT-IR

Abstract:

Introduction. One of the most significant challenges in modern materials science is increasing the reliability and durability of tools and machine parts. To address this issue, it is essential to develop high-hardness coatings with enhanced properties. Typically, high-energy techniques are employed for this purpose, but they require complex and costly equipment, limiting their widespread use. Therefore, problem of creating such coatings remains a significant challenge. An effective and affordable approach to creating these coatings on steel products is microarc surface alloying from a coating

Abstract:

High-density polyethylene (HDPE)/silica composites with different silicon dioxide fraction were prepared by the melting blend method. The effects of silicon dioxide content on the thermal properties and mechanical properties were mainly investigated. The results show that the thermal degradation of the composites shifts towards higher temperatures as the concentration of silicon dioxide is increased. With increasing silica dioxide content, the tension yield strength of HDPE/silicon composites increased, but its breaking elongation decreased. When silicon dioxide content is 5 %, the tension yie

Welding aluminum is very important in engineering, particularly in the aircraft and automobile industries. Its recommended properties such as thermal conductivity which is a high value, the coefficient of thermal expansion which also has a high value, hydrogen high solubility, oxide coating e.g., High strength-to-weight ratio, electrical conductivity, and all these properties have a high ratio for aluminum alloys. On the other side, aluminum has some properties that affect its mechanical behavior, for example, surface finish, tear resistance, mechanical strength, and thermal resistance. Theref

Abstract:

Increasing interest for industrial use of thermally sprayed coatings leads to development in most thermal spraying technologies, including atmospheric plasma spraying (APS). The latest cascaded torch SinplexPro from Oerlikon Metco incorporates the efficiency advantages of cascaded arc technology into a single-cathode spray gun. It leads to more stable plasma arc across a wide range of gas flows, mixtures and pressures and also highly increases powder throughput. Thermal sprayed molybdenum coatings are widely used for improving wear resistance and sliding properties in many mechanical applicati

Toluene, n-heptane, and methane were studied as carbon sources during the synthesis of Mo2C. Ammonium heptamolybdate ((NH4)6Mo7O24·4H2O), molybdenum dioxide (MoO2), orthorhombic molybdenum trioxide (α-MoO3), and a low crystallinity molybdenum oxide (MoOx) were employed as metal precursors and their conversion into the carbide phase was followed by time-resolved X-ray diffraction from synchrotron radiation. Thermal treatment was carried out from 298 K up to 1023 K and the evolution of gases analyzed by mass spectrometry. The resulting carbidic phase obtained using methane/H2 was hexagonal β-Mo2

Abstract:

As a kind of white paint, ZnO/silicone thermal control coatings are used commonly in space. In order to implement more effective thermal control in space, nanotitanium dioxide was doped to the coatings. In this paper, different percent of nanotitanium dioxide was appended to the coatings, and thermal control principle was discussed. Optical properties of these coatings were discussed by spectrophotometry and infrared reflectometer. The experimental results show that solar absorptance (αs) of nanotitanium dioxide doped ZnO/silicone thermal control coating is lower in all wavelength region than

Abstract:

Substoichiometric molybdenum oxide ceramics have aroused widespread interest owing to their promising optical and electrical performance. In this work, the thermal stability and decomposition mechanism of Mo9O26 and Mo4O11 at 700–1000 °C and 700–1100 °C were investigated, respectively. Based on this information, MoOx (2 < x < 3) bulk ceramics were prepared by spark plasma sintering (SPS). The results show that Mo9O26 is stable up to 790 °C in an argon atmosphere. As the temperature rises, it decomposes into Mo4O11. Mo4O11 can exist stably at 830 °C, beyond which it will convert to MoO2.

Abstract:

Carbon-neutral hydrogen production is of key importance for the chemical industry of the future. We demonstrate a new thermal catalytic route for the partial reforming of ethanol into hydrogen and acetic acid with near-zero carbon dioxide emissions. This reaction is enabled by a catalyst containing a high density of atomic Pt 1 and Ir 1 species supported on a reactive alpha-molybdenum carbide substrate, achieving a hydrogen production rate of 331.3 millimoles of hydrogen per gram catalyst per hour and an acetic acid selectivity of 84.5% at 270°C, and is therefore more energy-efficient compared
