We report the synthesis and electrochemical performances of the hybrid architecture of rhodium oxide (Rh2O3) nanofibers (NF) and highly single crystalline RuO2 nanowires (NW) by combining the electrospinning process and a simple recrystallization process. The amorphous Ru(OH)3·xH2O precursors a...

Both pH-sensitive and glucose-responsive rhodium oxide nanocorals (Rh2O3 NCs) were synthesized through electrospinning followed by high-temperature calcination. The as-prepared Rh2O3 NCs were systematically characterized using various advanced techniques including scanning electron microscopy, X...

The Rh-catalyzed direct selective oxidation Heck reaction of benzamides with allylic esters has been developed for the synthesis of amides and isoquinolin-1-ones. According to the functional groups on N-atom, benzamides or isoquinolin-1-ones were synthesized under optimal reaction conditions. Th...

We evaluated the potential of zinc rhodium oxide (ZnRh2O4) as a carbon dioxide (CO2) reduction photocatalyst with the aid of triethanolamine (TEOA) as an electron donor and demonstrated that ZnRh2O4 was able to reduce CO2 to carbon monoxide (CO) under infrared light. Gold (Au) loading onto ZnRh2...

A rhodium modification of aluminide coating on Mar-M247 superalloy was performed by electrodepositing of 0.5 μm thick rhodium layer followed by chemical vapour aluminizing. It was found that rhodium dissolves in the aluminide coating. Oxidation resistance of undoped coating is worse than the rh...

Rhodium (Rh) oxide thin films were prepared by reactive sputtering at different substrate temperatures under an oxygen or water (H2O) vapor atmosphere, and their crystal structure, density, optical properties, and electrochromic properties were investigated. The film density decreased with decre...

The alleged formation of La-clusters in silicate glasses has received an overall consensus. However, recent and the current experimental results do not support this hypothesis for the structural role of La2O3 in glasses. Therefore, here we propose a new model for the assignment of the peaks in N...

In this work, the surface of graphene oxide was functionalized with lanthanum to produce porous flowered graphene oxide‑lanthanum fluoride (GO-LaF) nanocomposite for adsorptive removal of As(V) from aqueous system. GO-LaF nanocomposite was characterized by TEM, SEM, XRD, and XPS analysis. Maximu...

Moniliella wahieum Y12T, isolated from biodiesel was used as a model organism to assess the use of lanthanum oxide (La2O3) (60–80 nm) and silver oxide (AgO) (10–40 nm) nanoparticles as potential fungal inhibitors. This is the first study to investigate the use of nanoscale La2O3 as a eukaryoti...

Metal oxides with oxygen vacancies can be exploited as a charge storage material for supercapacitor. This work demonstrates synthesis of lanthanum molybdenum oxide (La2Mo2O9, LMO) using different calcination temperatures (300, 400, 500, 600 and 700 °C). As prepared LMO500 illustrates its utiliz...

A systematic study on radiation decontamination in lanthanum oxide production from ion-adsorption rare earth ores in China was conducted. The distribution characteristics of radiation levels during the production process was clarified, and effective measures for radiation decontamination were pr...

Phosphate glasses are special class of optical glasses composed with metaphosphate of different metals. When rare earth elements are added to glass matrix as dopant, it improves glass melting and also enhances some unique glass properties. Lanthanum oxide doped Phosphate glass system were prepar...

In this study, a lanthanum cobaltite (LCO) “self-pulverisation” mechanism was investigated in an attempt use a novel concept when developing materials. The results confirmed that hydroxylation of a small amount of excessive La2O3 in LCO into La(OH)3 caused self-pulverisation of bulk LCO, which...

To discover more derivatives with better glucose-lowering efficacy compared with berberine, twenty-three novel compounds with 4,7,12,12a-tetrahydro-5H-thieno[3′,2′:3,4]pyrido[1,2-b]isoquinoline or 5,8,12,12a-tetrahydro-6H-thieno[2′,3′:4,5]pyrido[2,1-a]isoquinoline cores were designed, synthe...

A series of novel 1, 2, 4-triazolo isoquinoline derivatives (8a-8p) were synthesized starting from 2-phenylethan-1-ol derivative (1) in a 7 step synthetic sequence. The key step in the scheme involves 1, 3-dipolar [3 + 2] cycloaddition of azomethine imine and ethyl cyanoformate as unknown reacti...

Nucleophilic aromatic substitution is a challenging task in radiochemistry. Therefore, a thorough evaluation and optimisation of this step is needed to provide a satisfactory tool for the routine preparation of [18F]fluorinated aromatic amino acids. Two methods, already proposed elsewhere, were ...

Treatment of N-acyl-2-methoxy-2-(trifluoromethyl)arylethylamines under Pictet–Gams conditions afforded 4-methoxy-4-trifluoromethyl-3,4-dihydroisoquinolines which were aromatised by base catalysed methanol elimination. Earlier we described the synthesis of 2-oxazolines by conducting the Pictet–...

We find that several protein kinase C (PKC) inhibitors, previously considered to be specific, directly inhibit voltage-dependent Na+ channels at their useful concentrations. Bisindolylmaleimide I (GF 1092037), IX (Ro 31-8220) and V (an inactive analogue), but not H7 (a non-selective isoquinoline...
