Two new ternary compounds in the TiO2-TiC system, Ti5C2O6 and Ti3C2O2, are reported for the first time based on ab initio evolutionary algorithm. Ti5C2O6 has a tube-structure in which sp(1) hybridized carbon chains run through the lattice along the b-axis; while in the Ti3C2O2 lattice, double TiO6 polyhedral are separated by the non-coplanar sp(2) hybridized hexagon graphite layers along the c-...

Supercapacitive properties of synthesised metal oxides nanoparticles (MO where M = Ni, Co, Fe) integrated with multi-wall carbon nanotubes (MWCNT) on basal plane pyrolytic graphite electrode (BPPGE) were investigated. Successful modification of the electrode with the MWCNT-MO nanocomposite was confirmed with spectroscopic and microscopic techniques. Supercapacitive properties of the modified el...

This study provides insight into the current evolution of New Development Bank (NDB). It examines role agency global South reshaping intergovernmental organizations (IGOs) in case Brazil's influence on NDB to expand its membership. In that process, this article homes admission Uruguay as a prospective member September 2021, first expansion Latin America and Caribbean (LAC). The shows membership...

Recent studies of microdiamonds from orogenic belts related to continental collisions induced experimentalists to explore new crystallization media possible for diamond synthesis. This has led to considerable progress in diamond-synthesis experiments under high pressures and high temperatures. Diamond was found to grow in a wide variety of systems, which drastically differ from the metal-solven...

Key constraints related to the nature of alteration and mineralization in geologically complex economically important iron oxide copper–gold (IOCG) systems remain highly speculative, especially, physicochemical characteristics hydrothermal fluids. This study was conducted on samples from Khetri Copper Belt (KCB) western India that hosts several IOCG-type deposits. The aims constrain qualitative...

introduction: dentin hypersensitivity (dh) is characterized by tooth pain arising from exposure of dental roots. in this study the efficiency of neodymium yttrium-aluminum-garnet (nd:yag) laser in association with graphite on dentinal surface changes as the alternative to the treatment of dh was evaluated. methods: sixteen noncarious human third molars were collected and sectioned into 5 parts ...

In this contribution, high ortho novolac resins modified with phenylboronic acid were synthesized. The thermal stability of novolac resins cured with hexamethylenetetramine (HMTA) and chemical states of B and N via a pyrolysis process were studied. For the cured o-novolac modified with phenylboronic acid, the temperature with maximum decomposition rate increased by 43.5 ̋C, and the char yield i...

In this paper, the N2O plasma oxides in-situ grown on CF4 plasma pretreated silicon substrate is proposed and demonstrated having excellent characteristics. Those are precise thickness control, low temperature fabrication, low leakage current, and high reliability. Those good features will enhance the scaling down ability of CMOS devices. The mechanisms that make the process success are also di...

The selection of an appropriate substrate is an important initial step for many studies of electrochemically active materials. In order to help researchers with the substrate selection process, we employ a consistent experimental methodology to evaluate the electrochemical reactivity and stability of seven potential substrate materials for electrocatalyst and photoelectrode evaluation. Using cy...

Cobalt was recovered electrogeneratively by using a batch cell. In this system, a spontaneous chemical reaction occurred where cobalt is reduced at the cathode and zinc is oxidized to produce a free flow of electrical energy without any external power supply. The performances of reticulated vitreous carbon (RVC) and porous graphite (PG) as cathodes were evaluated based on the time and percentag...
