We have investigated some anodic and cathodic transformations using boron doped diamond (BDD) electrodes. The oxidn. of a propargylic alc. as well as the arom. side chain oxidn. in water as electrolyte did not yield the desired products in high yield and s ...
The electropolishing of a B-doped diamond (BDD) film deposited by CVD was studied in HOAc-H2SO4 media. The electropolished surface was characterized by SEM, XPS, and electrochem. measurements. In 1 M H2SO4 no polishing of the surface occurred even after pr ...
Due to their high hardness, high melting point and high chemical stability, transition metal nitrides present a great interest for various applications. This work constitutes a contribution to the understanding of the properties of Nb based binary and tern ...
Bimetallic Pt/Sn nanoparticles, synthesized by the microemulsion method, have been investigated once deposited on a boron-doped diamond (BDD) substrate electrode. Nanoparticles are in the nano-size domain and their effective composition corresponds to thei ...
This paper deals with the electrochem. reactivity of B doped diamond (BDD) electrodes. A comparative study was carried out to show the influence of the presence of graphitic micro-domains upon the surface of these films. Those graphitic domains are sometim ...
The methoxylation of p-tert-butyltoluene (TBT) in CH3OH-H2SO4-H2O soln. has been investigated on graphite and boron-doped diamond (BDD) anodes. Different reaction intermediates have been found on BDD and graphite. In fact BDD electrodes favor the formation ...
Carbon-carbon bond cleavage of 1,2-diphenyl-ethanes in CH3OH-H2SO4-H2O electrolyte on a boron-doped diamond (BDD) electrode has been investigated electrode using 1,2-di-(p-tert-butylphenyl)-ethane and 1,2-dimethoxy-1,2-di-(p-tert-butylphenyl)-ethane as mod ...
A method based on microindentation is developed to determine the fracture toughness K-1c of a thin film bonded to a brittle substrate. Using an easily fabricated sample having a partially coated substrate, indentation on the uncoated portion of the substra ...
Two methods were used for the deposition of Pt particles on synthetic B-doped diamond (BDD) surfaces: chem. deposition and electrodeposition under potentiostatic conditions. However, electrodeposition leads much higher Pt dispersion than chem. deposition. ...
The electrochem. properties of IrO2 and RuO2 nanoparticles, deposited on synthetic B-doped diamond (BDD) surfaces, are discussed. After a description of the prepn. procedure and the morphol. characterization of BDD/IrO2 and BDD/RuO2 samples, the dispersion ...
