Bipyridyl appended ruthenium alkynyl complexes have been used to prepare a range of binuclear homo-metallic ruthenium and hetero-metallic ruthenium-rhenium complexes. The two metal centers are only weakly coupled, as evinced by IR and UV-vis spectroelectrochemical experiments and supported by quantum chemical calculations. The alkynyl complexes of the type [Ru(C≡Cbpy){Ln}] ({Ln} = {(PPh3)2Cp}, ...

The lithiation of the NHC ligand backbone in Cp(CO)2Mn(IMes) followed by transmetalation on C4 carbenic position with Cp(CO)2FeI led to heterobimetallic complex Cp(CO)2Mn(?-dIMes)Fe(CO)2Cp bearing anionic ditopic imidazol-2,4-diylidene dIMes ligand. Subsequent treatment later TfOH induced a selective decoordination [Cp(CO)2Mn] fragment form cationic abnormal [Cp(CO)2Fe(aIMes)](OTf), which was f...

In this work we report strategies to nucleate bimetallic nanoparticles (NPs) made by gas phase synthesis of elements showing difficulty in homogeneous nucleation. It is shown that the nucleation assisted problem of bimetallic NP synthesis can be solved via the following pathways: (i) selecting an element which can itself nucleate and act as a nucleation center for the synthesis of bimetallic NP...

Bimetallic parts are used in many industries for weight and cost reduction of workpieces working under high loads and wear. One application for this type of composite material is in automotive industry. In this work the tool wear and cutting forces in the face milling of bimetallic parts made of aluminum and cast iron were investigated. A356 and GG25 alloys that are common materials for bimetal...

Three near-infrared (NIR-I) optical theranostic systems were synthesized, characterized and studied in vitro vivo. These original homo-bimetallic gold(I)-based aza-BODIPY complexes proved to be trackable through imaging cells mice. They display anti-proliferative properties micromolar range against human murine cancer cell lines (4T1, MDA-MB-231, CT26, SW480). Moreover, the injection of most pr...

A catalytic site typically consists of one or more atoms of a catalyst surface that arrange into a configuration offering a specific electronic structure for adsorbing or dissociating reactant molecules. The catalytic activity of adjacent bimetallic sites of metallic nanoparticles has been studied previously. An isolated bimetallic site supported on a non-metallic surface could exhibit a distin...

A rapid, template-free method was developed to prepare magnetic, bimetallic Co-Cu nanowires via liquid phase reduction and metal replacement under an external magnetic field. The characterization results confirmed that the as-prepared product was bimetallic Co-Cu nanowires with a desirable linear structure. Additionally, the magnetic hysteresis loop showed that the bimetallic Co-Cu nanowires we...

The production of electricity in a greener and more sustainable way by employing renewable sources is great challenge modern times. Photovoltaic systems represent an important possibility because sunlight the most abundant source. In this review article, recent studies (from 2018 to present) involving novel iron copper complexes employed as dyes Dye-Sensitized Solar Cells (DSSCs) are reported; ...

For a long time biomimetic oxidation catalysis was mainly associated with metal porphyrin complexes. Phthalocyanine complexes, also belonging to large family of macrocyclic complexes have been under-investigated as catalysts until recently. In this review, we present the development phthalocyanine catalytic chemistry at IRCELYON topical focus on contributions from our group during last 20 years...
