摘要:
Semiconductor materials such as silicon particles are doped by mixing the semiconductor material with a solution having a dopan and a solvent. The solvent is removed from the wetted surface of the particles of the semiconductor material, thereby yielding particles that are substantially free from the solvent and are uniformly coated with the dopant.

摘要:
A combined cycle dual closed loop electric generating system, comprising a gas turbine assembly (comprising a combustion chamber, a compressor, a first pump, a first driveshaft, a gas turbine and a first generator) and a steam turbine assembly (comprising a second pump, a second driveshaft, a steam turbine and a second generator). Said first portion of said working fluid circulates through said gas turbine assembly and a first heat exchanger. Said second portion of said working fluid circulates through said steam turbine assembly and said first heat exchanger. Said first heat exchanger transfers a first heat energy from said gas turbine loop to said steam turbine loop. Said gas turbine assembly generates a first portion of an electric output. Said steam turbine assembly generates a second portion of said electric output.

A string for use in a string ribbon crystal has a base portion with a refractory material, and an externally exposed layer radially outward of the refractory material. The base portion has a coefficient of thermal expansion that is generally matched with the coefficient of thermal expansion for silicon. The externally exposed layer has a contact angle with silicon of between about 15 and 120 degrees.
摘要:
An enhanced anaerobic adhesive composition containing microencapsulated metal ions is disclosed. Microencapsulated metal ions, such as iron oxide, copper naphthenate, cobalt naphthenate, ferrocene, and ferrocene derivatives, act as bonding sites in the composition, such that the composition achieves more complete polymerization in a shorter curing time. The curing properties and the cure quality are significantly improved by the inclusion of microencapsulated metal ions. The composition can be used to bond metal and plastic substrates.

摘要:
A method of growing ribbon crystal provides a crucible containing molten material, and passes at least two strings through the molten material to produce a partially formed ribbon crystal. The method then directs a fluid to a given portion of the partially formed ribbon crystal to convectively cool the given portion.
