The serious potassium loss during the activation process of carbon materials is a troublesome issue that should be highly addressed due to its unfavorable affect to environment and industrialized application. In this study, the co-activation technology was investigated and demonstrated on its po...

Recent interest in joining aluminum to steel necessitates a critical understanding of growth kinetics of various intermetallic phases that form across the mixed material interface. In order to understand the individual effect of ternary alloying elements present on iron side, growth kinetics of ...

Zero-valent iron has been intensively investigated in chemical reduction of nitrate in water, but the reduction requires acidic or weak acidic pH conditions and the product of the reduction is exclusively ammonium, an even more toxic substance. Zero-valent aluminum is a stronger reductant than i...

Pistacia lentiscus L. (Anacardeaceae), a largely distributed plant in the Mediterranean region, has long been used in human food, pharmaceutical industry and traditional medicine. P. lentiscus leaves are well known as a rich source of antioxidant polyphenols that may play a potential role in the...

Soil is the natural medium for plant growth, and its chemical property is one of the most important factors for metabolic process of phytochemicals. Therefore, revealing the soil chemical property-crop effects will strongly improve the cultivation technology for higher yield and quality. Glechom...

p-Arsanilic acid (p-ASA) is widely used as feed additives in animal production, and its transformation in environment media may cause arsenic contamination of soils and waters. It is essential to find a technology to effectively treat p-ASA, and meanwhile greatly decrease the mobility of the ars...

The objective of the investigation is to evaluate the influence of the Zener-Hollomon parameter on substructure and texture evolution in iron-containing wrought aluminium alloys (type AA8011). Methods applied are X-ray texture analysis, electron backscatter diffraction (EBSD) and optical microsc...

Iron (Fe) salts are widely used to remove phosphorus (P) in wastewater treatment plants (WWTPs). Understanding the existing species of iron-phosphorus compounds (FePs) in sludge is conducive to P recovery. In this study, the chemical equilibrium modeling software, sequential chemical extraction ...

The ionization efficiency of aluminum was measured in the laboratory over an extended velocity range of 10.8–73.4 km/s and compared to available models. The measurements were made by shooting submicron-sized aluminum dust particles into an air chamber using the University of Colorado's dus...

A new high photoluminescent metal–organic complex is proposed as an optical marker for the indentification of gunshot residues (GSR) produced from firearms. The marker containing Eu3 + ion was synthesized producing the [Eu(PIC)3(NMK)3] complex, where PIC is picric acid and NMK is n-methyl capro...

IntroductionThe purpose of this randomized clinical study was to evaluate the efficiency of erbium, chromium-doped:yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser irradiation combined with a resin-based tricalcium silicate material and calcium hydroxide in direct pulp capping for a 6-m...

This study reported an environmentally benign approach to iron(III) extraction using undiluted Aliquat 336. This technique was then applied for iron(III) removal from coal mining waste (CMW) hydrochloric acid leach liquor to produce high purity aluminum chloride. The extraction behavior, loading...

A novel Zn-Cu-Ni ternary mixed oxide with a molar ratio of 1:4:1 was synthesized in the current study via coprecipitation method. The material was characterized by Fourier transform infrared (FTIR), scanning electron microscope and thermogravimetric-differential thermogravimetric (TG-DT) analysi...

Perfluorooctanoic acid (PFOA) is widespread in the environment, which causes serious health and safety concerns. A mechanistic study on reductive defluorination of PFOA by titanium(III) citrate in the presence of catalysts was conducted. Vitamin B12 was used to catalyze reduction reactions by sh...

The construction of a potentiometric titanium(III)-selective electrode based on methylcalix[4]resorcinarene (CMCR) incorporated into a poly(vinyl chloride) (PVC) matrix is reported. The polymeric membrane incorporates 8.0 mg CMCR as an electroactive sensing material, 59.0 mg dioctylphthalate (DO...

This work presents an electrochemical study of Ti3+ and Al3+ in the NaCl-KCl-AlCl3-Ti2O3 at 1123K. Transient electrochemical techniques show that Ti3+ ions are reduced to Ti metal by a two-step mechanism involving the exchanges of one and two electrons. The electrochemical co-reduction of Ti3+ a...

The extraction of titanium (Ti(IV)) from chloride medium by Bis-(2-ethyhexyl) phosphoric acid (D2EHPA) in kerosene has been studied as a function of contact time, the concentration of the extractant in the organic phase and the temperature. The study has been performed at different metal ion con...

Vapors of AlCl3 and of TiCl4 were adsorbed on SBA-15 at 20–100 °C. The volatile compounds adsorbed on the surface were hydrolyzed by water vapor at 25 °C, and the product of hydrolysis was dried at 80–200 °C. The above procedure results in a metal-modified silica with specific surface area ...

A continuous worldwide increase in scandium (Sc) criticality leads to a quest for secondary scandium resources. Among them, bauxite residue (BR) – a waste product from alumina refineries – often contains substantial amounts of scandium. However, the complexity in BR composition drives the need...

Problems caused by residual organics in treated water include the formation of disinfection by-products (DBP) following reaction with chlorine and being a substrate for microbial regrowth in the drinking water distribution system. Dissolved organic matter (DOM) can only be partially removed by c...
