The influence of 0-0.1 wt.% Ni on the microstructure and fluidity length of Sn-0.7Cu-xNi

Michel Rappaz, Tina Ventura

Alloys based on the Sn-0.7Cu-xNi system are potential Pb-free solders. In this paper we report on the solidification characteristics and microstructures of Sn-0.7Cu alloys containing 0-1,000 ppm nickel. The microstructural observations show that increasing ...

Synthesis of Protected Chiral Vicinal Diaminoalcohols by Diastereoselective Intramolecular Benzylic Substitution from Bistrichloroacetimidates

Jieping Zhu

An efficient synthesis of chiral dihydrooxazines from 1-aryl-2-amino-propane-1,3-diols via the corresponding bistrichloroacetimidate intermediates has been developed. In this transformation, one trichloroacetimidate acts as a leaving group and the other ac ...

Proton shuttles and phosphatase activity in soluble epoxide hydrolase

Matteo Dal Peraro

Recently, a novel metal Mg2+-dependent phosphatase activity has been discovered in the N-terminal domain of the soluble epoxide hydrolase (sEH), opening a new branch of fatty acid metabolism and providing an additional site for drug targeting. Importantly, ...

Conversion analysis of acrylated hyperbranched polymers UV-cured below their ultimate glass transition temperature

Yves Leterrier, Lars Schmidt

The photo-curing behavior of reactive blends of dipentaerythritol penta/hexaacrylate (DPHA) with an acrylated hyperbranched polyester and an acrylated hyperbranched polyether was investigated by means of photo differential scanning calorimetry. The chemica ...

Preparation of beta-amino or alpha ,beta-diamino esters derived from serine

Jieping Zhu

The invention relates to the prepn. of esters R1R2NCH2CH(Nu)CO2R3 (R1-R3 are protecting groups and Nu is a nucleophilic group) by reaction of R1R2NCH(CH2-Y)CO2R3 (Y is a leaving group) with a nucleophile. Thus, treatment of (R)-Bn2NCH(CH2O3SMe)CO2Me with N ...

Importance of the structure of vancomycin binding pocket in designing compounds active against vancomycin-resistant enterococci (VRE)

Jieping Zhu

16-Membered meta,para-cyclophanes mimicking the vancomycin binding pocket (D-O-E ring) are designed and synthesized. The structural features of these biaryl ether contg. macrocycles are: (a) the deletion of the carboxyl group of vancomycin's central amino ...

Wittig rearrangement of lithiated allyl aryl ethers: a mechanistic study

A -75 DegC, alpha-lithiated allyl Ph ether undergoes mainly the Wittig rearrangement to afford, after acidic hydrolysis, 1-phenyl-2-propen-1-ol as the main product. A second metalation taking place at one of the ortho positions is the sole competing side r ...

Subgrid-scale modeling of reacting scalar fluxes in large-eddy simulations of atmospheric boundary layers

Fernando Porté Agel

In large-eddy simulations of atmospheric boundary layer turbulence, the lumped coefficient in the eddy-diffusion subgrid-scale (SGS) model is known to depend on scale for the case of inert scalars. This scale dependence is predominant near the surface. In ...
