Solvent extraction can be operated as a batch process or in counter-current mode. The preference for an extractant changes depending on the mode of operation. The extraction kinetics and isotherms are studied for the extraction of palladium using various LIX reagents. It was found that LIX 64N i...

Two kinds of xylan/palladium catalysts (PACMX-Pd and EDAX-Pd) were simply fabricated by integrating two N bidentate ligands into the skeleton of oxygen-rich xylan and followed with the in-situ reduction of palladium. The Pd loading in PACMX-Pd and EDAX-Pd nanocomposites was 0.353 mmol/g and 0.30...

Supported catalysts with molecularly dispersed, uniform palladium species were synthesized by the method of grafting. New specific synthesis protocols were developed in order to exclude self-reduction and agglomeration of palladium during immobilization. The successful synthesis of isolated mono...

Oxidation reaction of glycerol has the probability of producing intermediate species that may be toxic to the catalyst surface and blocks the catalyst function. Thus this study presents the performance and durability of glycerol fuel cell with novel catalyst, Palladium-Aurum catalysts supported ...

Metal oxide-supported palladium hydroxide (Pd(OH)2/MOx) catalysts enabled the oxidative intramolecular couplings of diarylamines to carbazoles and diarylethers to dibenzofurans via double aryl CH bond functionalizations with molecular oxygen as the sole oxidant. While supported PdO, Pd, and pall...

Various primary and secondary benzylic alcohols were efficiently oxidized to aromatic aldehydes and aromatic ketones with iodic acid in DMF at 60 °C for 2 h and with iodic acid in the presence of TEMPO (5 mol %) in DMF at room temperature, respectively. The former method was effective for the o...

The structures, energetics, and thermodynamic properties of HIO3 isomers (HOOOI, HOOIO, HOIO2, and HIO3) have been computed using CCSD(T)/CBS theoretical method. The spin orbit corrections (SOC) have also been evaluated for the each iodine-containing molecule. The SOC value decreases as the iodi...

Iodine oxides are of interest as biocidal components in energetic application such as thermites due to their high energy release and biocidal agent delivery. In this study, various iodine oxides/iodic acids, including I2O5, HI3O8 and HIO3, were employed as oxidizers in thermite systems. Their de...

We present a facile synthesis of europium-doped gadolinium sulfide (GdS:Eu3+) opto-magnetic nanoparticles (NPs) via sonochemistry. Their photoluminescence and strong paramagnetic properties enable these NPs to be utilized as an in vitro cell imaging and in vivo T1-weighted MR imaging probe. The ...

CdS, Cd0.98Gd0.02S, and Cd0.96Gd0.04S quantum dots (QDs) have been fabricated by solvothermal method and found to form in cubic phase. Raman spectra displayed first as well as second order longitudinal modes of CdS QDs. Transmission electron microscopy images depict the nearly spheroid particles...

Zinc Sulphide doped with Gadolinium (ZnS: Gd) quantum dots have various scientific and engineering applications in electronics, nonlinear optical devices for communication, and optical computers. The material is an excellent light transmission material with high refractive index 2.27, makes usef...

This study presents a novel akaganeite sorbent derived from waste bauxite residue (RMA) for the treatment of arsenic contaminated waters. The performance of the developed sorbent was compared against a commercial material (granular ferric hydroxide (GFH)) in order to contextualise the sorption c...

In order to clarify the formation mechanism and conditions for akaganeite in long-term exposure, the influence of the former corrosion results on akaganeite formation was investigated by simulated experiments in laboratory. The combination of XRD, FTIR, SEM and EPMA enabled the identification of...

Akaganeite, a Cl-bearing Fe(III) (hydr)oxide, has been recently discovered in Yellowknife Bay in Gale crater on Mars by the Mars Science Laboratory (MSL) Curiosity Rover. Akaganeite was associated with sulfate and sulfide minerals at Yellowknife Bay indicating that sulfate ions could be present ...

Several samples of pure and Al-substituted akaganeites with somatoid (SOM), rod-like (ROD) and nano-crystals (NANO) morphologies were synthesized and fully characterized. The specific surface areas and the total pore volume varied in the trend SOM  ROD > NANO. This parameter remained unchanged w...

Upon analysis of the reported crystal structure of PAK4 inhibitor KY04031 (PAK4 IC50 = 0.790 μM) in the active site of PAK4, we investigated the possibility of changing the triazine core of KY04031 to a quinazoline. Using KY04031 as a starting compound, a library of 2, 4-diaminoquinazoline deri...

Novel 2-chloro-4-anilino-quinazolines designed as EGFR and VEGFR-2 dual inhibitors were synthesized and evaluated for inhibitory effects. EGFR and VEGFR-2 are validated targets in cancer therapy and combined inhibition might be synergistic for both antitumor activity and resistance prevention. T...

The nucleophilic aromatic substitution of 4-chloroquinazoline and 6-bromo-4-chlorothieno[2,3-d]pyrimidine with 1-aryl-2-fluoroethanols as nucleophilies has been studied focusing on the use of carbonate bases in combination of environmental acceptable solvents. The conversion rate depended on the...

Compounds that induce cancer cells to differentiate are clinically effective for several types of malignancies. The 1,25-dihydroxyvitamin D3[1,25(OH)2D3(C)] induces leukemic cells, including HL-60, to differentiate and/or no longer proliferate, but it causes hypercalcemia. Development of vitamin...

It has been previously demonstrated that the WDNM1 gene is downregulated in metastatic rat mammary adenocarcinomas. Detailed analysis of the structure of WDNM1 mRNA reveals the presence of two transcripts generated by alternative splicing of a single exon. The unspliced version possesses an in-f...
