In this work, a comprehensive study on the polyol synthesis of platinum supported on reduced graphene oxide (Pt/rGO) catalysts, including both ex-situ and in-situ characterizations of the prepared Pt/rGO catalysts, was performed. The polyol synthesis was studied considering the influence of the ...

A strategy has been explored to design a novel network of reduced graphene oxide (rGO)/nickel oxide (NiO) nanohybrids with optimized Ni2+/Ni3+ ratio for the fabrication of compact, flexible, and large area Pt-free dye sensitized solar cells (DSSCs). The rGO/NiO nanohybrids were synthesized by a ...

The current study aims to elucidate the possible reasons for the significantly different pharmacological behavior of platinum(IV) complexes with cisplatin-, carboplatin- or nedaplatin-like cores and how this difference can be related to their main physicochemical properties. Chlorido-containing ...

The behavior of platinum and gold electrodes in the hydrophobic room-temperature ionic liquid (RTIL) N,N-Trimethylbutylammonium Bis(trifluoromethanesulfonyl)imide ([N4111][NTf2]) was investigated using transient electrochemistry e.g. voltammetry and chronoamperometry. As previously observed and ...

A serious of carbohydrate-conjugated platinum(IV) complexes in the form Pt(L2)(A2)(OH)R based on the clinical drug cisplatin and oxaliplatin were designed, synthesized and evaluated as antitumor agents in vitro and in vivo. The conjugates possessing both pH and redox dual-responsive properties e...

The oxidations of CO and C3H6 are important model reactions for environmental cleanup reactions such as the purification of automotive exhaust gases from diesel engine or of volatile organic compounds. Mn-modified hexagonal YbFeO3 (Mn-h-YbFeO3), synthesized by a solvothermal method, exhibits exc...

An existing chemistry for the selective oxidation of methane to methanol is the homogeneous platinum(II)-based Shilov system, but limiting its practical implementation is its use of platinum(IV) as the terminal stoichiometric oxidant. However, an examination of the Shilov cycle suggests that ele...

The recovery of platinum group elements (PGEs) which are normally lost during processing, can add value especially in times of declining commodities prices, high operational costs and weak economic growth. The recovery of platinum (Pt(IV)) from aqueous solutions with zeolite functionalised with ...

Platinum (Pt) nanoparticles of varying average diameters decorated on exfoliated reduced graphene oxide (Pt/rGO) of various functionalities have been synthesized by monitoring the temperature of co-reduction of PtIV and GO. The as-synthesized composites are characterized by X-ray diffraction, sp...

We performed simulations with density functional theory and molecular dynamics to investigate the interaction of CO, CO2, and CH4 with the surface of a [0001] titanium slab made of four titanium layers. Our simulations were performed at atmospheric pressure and 300 K. We found that the CO molecu...

More than 130 pure rotational transitions of 46TiO, 47TiO, 48TiO, 49TiO, 50TiO, and 48Ti18O are recorded using a high-resolution mm-wave supersonic jet spectrometer in combination with a laser ablation source. For the first time a mass-independent Dunham-like analysis is performed encompassing r...

Nanocomposites with 10 or 20 wt% additives of nonstoichiometric titanium monoxide TiOy (y = 0.92; 1.23) to hydroxyapatite (HAp) were prepared. The nanocomposites were studied by using of X-ray diffraction analysis (XRD), high-resolution transmission electron microscopy (HRTEM), infrared (IR) and...

The present work aims to investigate the influence of neodymium addition on the microstructure, mechanical and thermal properties of Mg-Si alloys. Different proportions of (0.3, 0.6, 0.9 and 1.2 wt.%) Nd has been added to the hypo (Mg-1.15Si) and hypereutectic (Mg-6Si) alloys. The microstructura...

Nanocrystalline neodymium disilicide was synthesized by co-reducing anhydrous neodymium trichloride and sodium fluorosilicate with metallic sodium in an autoclave at 650 °C. The as-prepared product was characterized and studied by X-ray powder diffraction, transmission electron microscopy and t...

The standard enthalpies of formation of some congruent-melting compounds in the binary systems Nd + X and Gd + X (where X = C, Si, Ge) have been determined by direct-synthesis calorimetry at 1473 ± 2 K. The following values of ΔH0f (kJ/g.atom) are reported: NdC2, −29.2 ± 1.4; NdSi2, −62.0 ± ...
