Photolithography methods and structures that reduce stochastic defects
Disclosed are embodiments of a multi-layer stack and photolithography methods and systems that employ such a stack. The disclosed multi-layer stacks include a photoresist layer on an underlayer. The photoresist layer and underlayer are made of different materials, which are selected so that valence and conduction band offsets between the underlayer and photoresist layer create an effective electric field (i.e., so that the stack is “self-biased”). When areas of the photoresist layer are exposed to radiation during photolithography and the radiation passes through photoresist layer and excites electrons in the underlayer, this effective electric field facilitates movement of the radiation-excited electrons from the underlayer into the radiation-exposed areas of the photoresist layer in a direction normal to the interface between the underlayer and the photoresist layer. Movement of the radiation-excited electrons from the underlayer into the radiation-exposed areas of the photoresist layer improves photoresist layer development and pattern resolution. |

Integrated, post-tensioned, building construction system
The present invention relates an integrated, post-tensioned building construction system that utilizes a rectangular array of interlocking block components for the shell of building structures. Internal tendons that pass through the interlocking blocks are affixed to beams at the base or foundation of the building walls and terminate above beams atop the building walls.

Method of production of fuels from biomass, from low quality coals and from wastes, residues and sludges from sew age treatment plants
The present invention concerns a method for the removal of inorganic components such as potassium, sodium, chlorine, sulfur, phosphorus and heavy metals, from biomass of rural or forest or urban origin or even mixture of different origin biomasses, from low quality coals such as peat, lignite and sub-bituminous/bituminous coals, from urban/industrial origin residues/wastes, which are possible to include as much organic—>5% weight—as inorganic—<95% weight—charge and from sewage treatment plant sludges. The desired goal is achieved with the physicochemical treatment of the raw material. The method can also include the thermal treatment, which can precede or follow the physicochemical one. The application of the thermal treatment depends on the nature and the particular characteristics of each raw material as well as on the feasibility analysis of the whole process in order to determine the optimization point in each case. |

Methods for producing aromatics and olefins
The presently disclosed subject matter provides methods for producing olefins and/or aromatics from coker naphtha. In a non-limiting embodiment, a method for producing aromatics includes hydrogenating the coker naphtha stream in the presence of a first catalyst to remove diolefins and sulfur, if any, to obtain a hydrogenated stream and subjecting the hydrogenated stream to aromatization in the presence of a second catalyst to produce an aromatic-rich stream that includes benzene, toluene and xylene. In certain embodiments, a method for producing olefins includes hydrogenating the coker naphtha stream in the presence of a first catalyst to remove diolefins and sulfur, if any, to obtain a hydrogenated stream and subjecting the hydrogenated stream to catalytic cracking in the presence of a second catalyst to produce an olefin-rich stream that includes ethylene, propylene and aromatics. |
