Interfacial intermetallic growth and strength of composite lead-free solder alloy through isothermal aging

John Botsis, Joël Cugnoni, Venkatesh Sivasubramaniam

The effects of particle reinforcement of Sn-4.0wt.%Ag-0.5wt.%Cu (SAC405) lead-free solder on interfacial intermetallic layer growth and strength of the ensuing joints through short-term isothermal aging (150 degrees C) were studied. Composite solders were ...

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 ...

Crystal and Electronic Structures of Magnesium(II), Copper(II), and Mixed Magnesium(II)−Copper(II) Complexes of the Quinoline Half of Styrylquinoline-Type HIV-1 Integrase Inhibitors

Philip Pattison

A new target in AIDS therapy development is HIV-1 integrase (IN). It was proven that HIV-1 IN required divalent metal cations to achieve phosphodiester bond cleavage of DNA. Accordingly, all newly investigated potent IN inhibitors contain chemical fragment ...

Growth mechanism of solution-deposited layers of the charge-transfer salt CuDDQ

Klaus Kern, Marko Burghard, Stephan Rauschenbach, Ralf Thomas Weitz

Charge-transfer (CT) salts such as copper-2,3-dichloro-5,6-dicyano-p-benzoquinone (CuDDQ) are promising components of reversible resistive memory switching devices. In the study presented here, we report on the composition of CuDDQ layers grown from aceton ...

Synthesis of galactofuranose-containing disaccharides using thioimidoyl-type donors

Ronan Euzen

Four galactofuranose-containing disaccharides have been prepared utilising various thioimidates [Galf-SC(NR)XR′] and suitably protected acceptors as key precursors. We observed that the efficiency of the coupling reactions was particularly dependent on the ...

Wetting in infiltration of alumina particle preforms with molten copper

Andreas Mortensen, Ludger Weber, Maryam Bahraini Hasani

The high-temperature wettability of alumina particulate preforms by copper is investigated by means of infiltration experiments conducted at 1473 K under low oxygen partial pressure. Wetting is quantified in terms of drainage curves, which plot the volume ...

Diffusion-controlled liquid bismuth induced intergranular embrittlement of copper

Vincent Laporte

The consequences of the contact between liquid bismuth and a copper bicrystal are investigated at 500°C. Atoms of bismuth are shown to penetrate and embritlle the copper grain boundary. Grain boundary concentration profiles of bismuth are obtained on fract ...
