Anelastic Effects of Phase Decomposition in 14-carat AuAgCu alloy

Daniele Mari, Robert Schaller, Iva Tkalcec Vâju

A relaxation peak has been observed in the internal friction spectrum of 18-carat AuAgCu yellow gold alloys at about 750K for 0.5Hz. It is related to the presence of grain boundaries, since it is absent in the spectrum of single crystals. For the 14-carat ...

Copper-Catalyzed Alkylation of Benzoxazoles with Secondary Alkyl Halides

Rosario Scopelliti, Xile Hu, Peng Ren, Isuf Salihu

Copper-catalyzed direct alkylation of benzoxazoles using nonactivated secondary alkyl halides has been developed. The best catalyst is a new copper(I) complex (1), and the reactions are promoted by bis[2-(N,N-dimethylamino)ethyl] ether. ...

Substance flow analysis as a tool for urban water management

Luca Rossi, Nathalie Chèvre Rossi

Human activity results in the production of a wide range of pollutants that can enter the water cycle through stormwater or wastewater. Among others, heavy metals are still detected in high concentrations around urban areas and their impact on aquatic orga ...

Development of a Hybrid MEMS BLDC Micromotor

Yves Perriard, Sebastiano Merzaghi

This paper addresses the design of a new hybrid microelectromechanical systems (MEMS) micromotor. It is a small three-phase axial flux brushless dc (BLDC) motor. The stator is developed following the almost-standard CMOS technology rules used for MEMS manu ...

Modeling and design of a hybrid MEMS motor

Yves Perriard, Sebastiano Merzaghi

This paper addresses the design of a new hybrid MEMS micromotor. It gives insights on the choices, which led to the fabrication of a small 3-phases axial flux BLDC motor. The stator is developed following the almost CMOS technology rules used for MEMS manu ...

Development of a Hybrid MEMS BLDC Micromotor

Yves Perriard, Sebastiano Merzaghi

This paper addresses the design of a new hybrid MEMS micromotor. It is a small 3-phases axial flux BLDC motor. The stator is realized following the almost CMOS technology rules used for MEMS manufacture and the coils have two copper layers. The rotor is ma ...

The strength of annealed, heat-strengthened and fully tempered float glass

Pieter Christian Louter

In the last two decades architectural glass has made an enormous leap from a secondary material to a material that combines structural and cladding roles. The structural role is a new and problematic one. In contrast to most other engineering materials the ...

Iron/copper-catalyzed C–C cross-coupling of aryl iodides with terminal alkynes

Pierre Vogel, Chandra Mouleeswara Rao Volla

Synergic effect of iron and copper salts as catalysts for the Sonogashira–Hagihara cross-couplings of aryl iodides with terminal alkynes is demonstrated. High yields of cross- coupled products are obtained under conditions that are smoother than those usin ...

Detection of proteins on membranes and in microchannels using copper staining combined with Scanning Electrochemical Microscopy

Hubert Girault, Niels Erik Lion

Scanning Electrochemical Microscopy (SECM) and copper staining are combined to achieve visualisation of proteins on surfaces. Proteins are adsorbed on a polyvinylidene fluoride (PVDF) membrane or on a polyethylene terephthalate (PET) surface and stained us ...
