Hydroxyapatite (HA) nanoparticles (NPs) doped with different radioisotopes for use as theranostic systems play an important role in scientific research nowadays due to their ability to simultaneously act in the treatment and diagnosis of various types of cancers. In this work, we describe the sy...

Copper-decorated carbon nanotubes (CNTs) have important applications as precursors for ultra-conductive copper wires. Tenorite-decorated CNTs (CuO-CNTs) are ideal candidates and are currently developed using laborious processes. For this reason, we have developed a facile and scalable method for...

Enhancing power conversion efficiency in organic-inorganic heterojunction solar cells faces several serious hurdles. Although standard TiO2 nanoparticles-based heterojunction solar cells are moderately efficient, the TiO2 nanostructure has several drawbacks including a disordered low surface are...

Light irradiation plays an important role in the oxidative dissolution of Sb2S3. A qualitative mechanism was proposed through simulated experiments to describe the dissolution reaction under various ambient conditions, specifically darkness/light and aerobic/anaerobic conditions. The pH-dependen...

Arsenic and antimony are environmental pollutants associated with several diseases, including skin cancer. One of the main sources of both elements is the oxidation of sulphide minerals, particularly arsenopyrite and therefore any of both elements is a concern in gold mining operations because a...

As the mineral particle size and the drug effect are not uniform, resulting in a single flotation rate constant cannot describe the flotation process accurately. In this paper, based on the results of stibnite batch flotation, the non-first-order kinetic model is proposed to describe the stibnit...

A novel leaching process for stibnite concentrates using ozone as oxidant has been studied in this paper. The main factors affecting the leaching rate such as leaching temperature, concentration of leaching agent, gas flow rate and liquid to solid ratio have been investigated comprehensively. In...

The flotation of stibnite with Pb2+ as an activator was examined with micro-flotation tests, inductively coupled plasma mass spectrometry (ICP-MS) experiments and density functional theory (DFT) calculations. It was found that at a pH of 6.5, the addition of Pb(NO3)2 notably improved the flotati...

This study investigated the leaching and electrowinning of antimony from a complex, high arsenic and gold-containing stibnite concentrate ore (As-Au-Sb ore) using slurry electrolysis (SE). The results indicated that the leaching efficiency of antimony was higher than 98%, and those of iron and a...

Stibnite is the main raw material employed to produce antimony. With the excessive exploitation of high-grade stibnite, low-grade stibnite become more and more important. This study aimed to introduce a vacuum process for recovering and enriching antimony from low-grade stibnite. At the pressure...

Thermal stability and heat dissipation of color converter are the key roadblocks for high-power white light-emitting diodes (LEDs) and laser diodes (LDs). In this work, we fabricated an efficient and heat-conducting color converter based on phosphor-sapphire composite (PSC) for white LEDs/LDs, i...

In this work, bulk sapphire crystal has been growth by the flame fusion technique (FFT) and investigated their physical, structural and optical properties. The crystal structure of growth sapphire was studied by X-Rays Diffractometer (XRD) and found to be Al2O3 structure. The density, refractive...

Phosphor-in-glass (PiG) is considered as a stable and efficient color converter for high-power white lighting due to its high thermal stability, excellent mechanical strength, and facile preparation process. However, the low thermal conductivity of PiG hinders the heat dissipation of phosphor, w...

Bismuth-borate glass, 50Bi2O3–50B2O3 (mol%), was prepared and employed to braze sapphire in air. Prior to the joining process, the structure and mechanical and thermal parameters of the glass were investigated. Additionally, the wettability of the glass on sapphire was found to be good. Subsequ...

Sapphire kerf waste (a fine powder) is a great potential source of high-purity α-Al2O3 and is currently discarded without reutilization, which is a waste of this resource and causes environmental problems, such as occupying space and generating dust. Herein, we report a feasible combined method...

Solid-gas reactions play an important role in many technologically important processes from ore smelting to hydrogen storage and the synthesis of functional materials. In situ investigations are very useful for unraveling basic steps of such reactions, rationalizing them and gaining control. For...
