We describe a recent case of presumed redback spider (Latrodectus hasselti) envenomation observed near Noumea in New Caledonia. This is the first local reported case in this archipelago, where L. hasselti is Currently considered a native species. We

The electromagnetic continuous pulling (EMCP) is a new growth process competing with directional solidification for the production of massive silicon ingots. The advantages of the EMCP are higher production rates, no crucible consumption and a more u

Electromagnetic continuous pulling (EMCP) process combines the advantages of the cold crucible melting (no pollution, no crucible consumption) with those of continuous casting (high material flow rate, uniform material structure and properties). It i

A model is established for comparing the solute distribution resulting from four solidification processes currently applied to semiconductor grade silicon: Czochralski pulling (CZ), floating zone (FZ), 1D solidification and electromagnetic continuous

A phase diagram is proposed for the solid-liquid equilibria in the silicon-rich corner of the Si-O-C system. It is calculated from the solubility data in binary systems, using the model of a regular solution to estimate the interaction coefficient fr

High temperature phase equilibria of the ternary system Nb-Al-Ti were investigated in cast and annealed alloys by SEM, X-ray diffraction, EPMA and TEM. A modified liquidus projection and an isothermal section at 1200°C are presented. The liquidus pr

Some billets of multicrystalline silicon were semi continuously solidified, using an inductive cold crucible. The outer surface of the billet shows that electromagnetic pressure limits the contact. The grain structure is entirely columnar. Grain orie
