Provided are methods of passivating active materials for use in electrochemical cells as well as active materials and cell components prepared using such methods. Active material particles may be combined with passivating material particles, and this combination may be mixed together using high shear mixing. The mixed combination may not include any solvents or binders. As such, drying mixing may be performed on this combination of the active material particles and passivating material particles. A passivating layer is formed on the active material particles during mixing. This passivating layer later prevents direct contact between the active material particles and the electrolyte while still allowing ionic exchange. Furthermore, the passivating layer may increase electronic conductivity between active material particles in an electrode. The passivating layer may be mechanically bonded to the surface of the active material particles rather than chemically bonded.

The present invention relates to methods for forming microelectronic structures in a semiconductor substrate. The method includes selectively removing dielectric material to expose a portion of an oxide overlying a semiconductor substrate. Insulating material may be formed substantially conformably over the oxide and remaining portions of the dielectric material. Spacers may be formed from the insulating material. An isolation trench etch follows the spacer etch. An optional thermal oxidation of the surfaces in the isolation trench may be performed, which may optionally be followed by doping of the bottom of the isolation trench to further isolate neighboring active regions on either side of the isolation trench. A conformal material may be formed substantially conformably over the spacer, over the remaining portions of the dielectric material, and substantially filling the isolation trench. Planarization of the conformal material may follow.

Embodiments of the invention prevent contact between a peripheral edge of a magnetic disk and a counter surface of a ramp when the magnetic disk is displaced. In one embodiment, a ramp is disposed near the peripheral side surface of a magnetic disk. The ramp has magnetic disk retainers each having slide surfaces and counter surfaces respectively facing the recording surfaces of the magnetic disk. Grooves or recesses are formed in the counter surfaces to define relief spaces. When the peripheral side surface of the magnetic disk is displaced toward the counter surface by shocks exerted on the magnetic disk drive, the relief space prevents the peripheral edge from coming into contact with the counter surface. Thus the amount of particles produced by the collision of the magnetic disk with the ramp can be reduced.
