As perovskite-type metal oxides are attractive catalysts for activating peroxymonosulfate (PMS), cobalt titanate (CoTiO3 (CTO)) is particularly promising as CTO consists of earth-abundant Ti and Co is the most effective metal for PMS activation. However, conventional preparation methods of CTO r...

The lead cobalt titanate nanoparticles were synthesized via the sol-gel technique followed by microwave heating at 750 °C for 45 min. The X-ray diffraction study revealed the formation of tetragonal PbCoTiO3 phases. The average crystallite size was found to be 26 nm. The surface morphology was ...

This work investigated the catalytic ability of modified cobalt-titanate nanowires (Co-TNW) on photodegradation of three antidepressants: amitriptyline (AMI), trazodone (TRA) and venlafaxine (VEN). The experiments were carried out with spiked tap water under UV–Vis radiation in the presence of ...

Recently, due to their high capacity and excellent cycle stability, bimetallic transition-metal oxides have attracted great interest from researchers for use as anode materials in lithium ion batteries. The main disadvantages of bimetallic transition-metal oxides are poor conductivity and easy a...

Assembly of the efficient flexible energy storage devices is indispensable for widening the application of the wearable electronics which require electricity for operating.

Novel pompon-like nickel-cobalt double hydroxide/graphene oxide (Ni(OH)2/Co(OH)2/GO) composites were successfully synthesized via a simple one-step solvothermal process. Their structure, morphology, surface and electrochemical properties were characterized by scanning electron microscopy(SEM), t...

Efficient, economical, and eco-friendly water splitting catalysts are in priority to replace the fossil fuels. In the presented work, reduced graphene oxide is formed through electrochemical reduction and applied as an effective interlayer between nickel foam substrate and nickel-cobalt hydroxid...

The development of an inexpensive, stable, and highly active electrocatalyst for oxygen evolution reaction (OER) is essential for the practical application of water splitting. Herein, we have synthesized an electrodeposited cobalt hydroxide on nickel foam and subsequently annealed in an air atmo...

A facile dissolution-regrowth strategy was developed in synthesis of hierarchical hollow nanospheres of cobalt silicate hydroxide (CSH-80) for maximizing cobalt active sites on unit mass basis, which is different from the conventional supported cobalt catalysts. Due to the unique design and elab...

BackgroundPositive patch-test results to nickel, cobalt, and chromate alone and in combinations with one another are well known to occur. Patient factors that may play a role in isolated and concurrent sensitization to these allergens have not been studied in the US population.

Plutonium uranium mixed oxide (MOX) fuels are being used in commercial nuclear reactors. The actinides in these fuels need to be analyzed after irradiation for assessing their behaviour with regards to their environment and the coolant. In this work the study of the local occurrence, speciation ...

ObjectiveTo assess remineralization of primary teeth enamel under the presence of fluoride, calcium and phosphorous ions using microhardness and surface roughness testing.

ObjectivesTo compare remineralization of enamel subsurface lesions by fluoride dentifrices with added calcium in a double-blind, randomized, cross-over, in situ study.

The ability of steel reinforced concrete to withstand long service life is ensured by the strong binding between the concrete and the rebar. Although rebar corrosion deterioration in the presence of chlorides is well known, it is important to note that these anions are never present in isolation...

Sodium chloride has various functions in bread, but its reduction is a topic that should be focused on due to nutritional recommendations.
