Pseudocapacitors, also known as one type of supercapacitors, have attracted significant attention of researchers as efficient energy storage devices with superior properties such as high power density, excellent reversibility, and long cycle lifetime...…
What is copper oxide?Copper and Oxygen, when combined, form magnetic materials, including copper oxide (I) and copper oxide (ll); both minerals are found in nature and have unique characteristics and particular uses. Copper oxide (II), or cupric oxid...…
Using lightweight elements/compounds and employing multi-electron reaction (MER) chemistry are two approaches used to develop high-energy-density materials for batteries. In this work, nanoscaled calcium hexaboride (CaB6) was prepared in one step by ...…
In particular, we focus on the fundamental properties and various nanostructured forms of CuO reported in the literature and summarize the different synthetic strategies. Precisely controlling the artificial process is critical because it helps obtai...…
What is Copper Oxide?There are two stable copper oxides, copper(II) oxide (CuO) and copper(I) oxide (Cu2O). Copper(I) oxide or cuprous oxide (Cu2O) is an oxide of copper. It is insoluble in water and organic solvents. Copper(I) oxide dissolves in con...…
Fumed silica is also known as pyrogenic silica because it is produced in flame pyrolysis of silicon tetrachloride or from quartz sand vaporized in a 3000 °C electric arc. Fumed Silica consists of microscopic droplets of amorphous silica fused into br...…
Fumed silica is an artificial substance, so it’s no surprise that it’s known by multiple names—Diatomaceous earth, Diatomaceous silica, Diatomite, Silicon dioxide (amorphous), and Vitreous silica, at least. In fact, before 1989, its official name was...…
A disparity in the water release from the foam concrete samples was noticed for two types of foaming agents. The rapid outflow of water from the models was observed in the foam concrete with the protein foaming agent for the curing conditions applied...…
Demand for copper oxide nanoparticles (CuO NPs) has grown tremendously, driven by penetration in electrical engineering and electronics, paints and coatings, semiconductors, energy storage, catalysts, and other fields. Nano-copper oxide is a widely u...…
An important place in the technology of foam concrete is the method of preparing a foam concrete mixture. There is separate and joint technology. For both methods, the structural and technological parameters of the mixing equipment used significantly...…
The pressure-induced transformation of the rare β-Fe2O3 phase has been studied for the first time, leading to the identification of a new iron(III) oxide polymorph, ζ-Fe2O3. The transformation of β-Fe2O3 into ζ-Fe2O3 occurs above 30 GPa, and the new ...…
Surprisingly, β-Fe2O3 was found to transform into a completely new crystal structure following the Rietveld refinement of the synchrotron radiation XRD patterns recorded at pressures above 30 GPa. The analyses were carried out adopting the following ...…
Copper oxide is an inorganic substance with the chemical formula CuO. It is a black oxide of copper, slightly amphiphilic and slightly hygroscopic. Insoluble in water, soluble in acid, stable to heat, and decomposes oxygen at high temperatur…
The upper material of sports shoes can be divided into natural leather, PVC, PU, nubuck, microfiber, mesh…
Today, smartphones have become an essential tool in people's lives for communication and everyday necessities. The "battery anxiety disorder" is a common condition that many people experience. People will feel nervous or anxious if their phone runs o...…
