A method and apparatus is provided for inhibiting scaling in an electrodeionization system and, more particularly, for increasing tolerance to hardness in the feed water to an electrodeionization unit by inhibiting precipitation of scale-forming metallic cations contained in the feed water and thereby increasing efficiencies of the electrodeionization system. Water to be purified is passed through an electrodeionization unit in which the flow in the diluting compartment is countercurrent to the flow in the concentrating compartment. This is to impede the migration of scale-forming metallic cations from the diluting compartment, through the cation exchange membrane, into the concentrating compartment and towards the concentrating compartment side of the anion exchange membrane, thereby preventing scale formation on the anion exchange membrane. The electrodeionization unit may be further modified by dividing the concentrating compartments into first and second compartments by a porous diaphragm or ion-conducting membrane. The porous diaphragm or ion-conducting membrane effectively eliminates convective transport of scale-forming metallic cations from the cation exchange membrane side of the concentrating compartment to the anion exchange membrane side of the concentrating compartment, thereby inhibiting scale formation on the anion exchange membrane.

A method used in fabrication of a recessed access device transistor gate has increased tolerance for mask misalignment. One embodiment of the invention comprises forming a vertical spacing layer over a semiconductor wafer, then etching the vertical spacing layer and the semiconductor wafer to form a recess in the wafer. A conductive transistor gate layer is then formed within the trench and over the vertical spacing layer. The transistor gate layer is etched, which exposes the vertical spacing layer. A spacer layer is formed over the etched conductive gate layer and over the vertical spacing layer, then the spacer layer and the vertical spacing layer are anisotropically etched. Subsequent to anisotropically etching the vertical spacing layer, a portion of the vertical spacing layer is interposed between the semiconductor wafer and the etched conductive transistor gate layer in a direction perpendicular to the plane of a major surface of the semiconductor wafer.

Yeast cells with a reduced general control response to amino acid starvation were found to have increased tolerance to butanol in the growth medium. The reduced response was engineered by genetic modification of a gene involved in the response, a GCN gene, to eliminate activity of the encoded protein. Yeast strains with an engineered butanol biosynthetic pathway and a genetic modification in a gene involved in the general control response to amino acid starvation, which have increased butanol tolerance, are useful for production of butanol.
