Embodiments of the invention generally provide a method for depositing films or layers using a UV source during a photoexcitation process. The films are deposited on a substrate and usually contain a material, such as silicon (e.g., epitaxy, crystalline, microcrystalline, polysilicon, or amorphous), silicon oxide, silicon nitride, silicon oxynitride, or other silicon-containing materials. The photoexcitation process may expose the substrate and/or gases to an energy beam or flux prior to, during, or subsequent a deposition process. Therefore, the photoexcitation process may be used to pre-treat or post-treat the substrate or material, to deposit the silicon-containing material, and to enhance chamber cleaning processes. Attributes of the method that are enhanced by the UV photoexcitation process include removing native oxides prior to deposition, removing volatiles from deposited films, increasing surface energy of the deposited films, increasing the excitation energy of precursors, reducing deposition time, and reducing deposition temperature.

A self-cooled oxidant-fuel burner consisting novel fuel and oxidant nozzles and three compartment refractory burner block design is proposed. The new oxidant-fuel burner can fire in high-temperature (2200 DEG F. to 3000 DEG F.) and high-particulate (or high process volatiles/condensates) furnaces without over-heating or causing chemical corrosion damage to it's metallic burner nozzle and refractory burner block interior. Using various embodiments of nozzle and block shape, the burner can offer a traditional cylindrical flame or flat flame depending on the heating load requirements. The new features of this burner include unique fuel nozzle design for the streamline mixing of fuel and oxidant streams, a controlled swirl input to the oxidant flow for desired flame characteristics, a controlled expansion of flame envelope in the radial and axial dimensions, and efficient sweeping of burner block interior surface using oxidant to provide convective cooling and prevent any build up of process particulates. In addition, a relatively thick wall metallic nozzle construction with heat conduction fins enable efficient heat dissipation from the nozzle tip and providing a maintenance free burner operation.

A system and a method for enhancing burning candle and improving volatiles performance with a tube having holes and/or cuts or a candle container having at least one inner-tube having holes and/or cuts, continuously supplying the fresh air through the holes and/or cuts, and supplying the fresh air to the foot of the burning wick, and for manufacturing the same.

A drying and upgrading device for lignite and a technological method thereof, relating to the lignite efficient utilization field. The invention comprises a chamber dryer for the lignite, a fluidized-bed pyrolysis device, a combustion device for the pyrolysed gas, and other adjuvant devices. The dried lignite is fed into the pyrolysis device, volatiles and liquid products are extracted, the volatiles are sent into the combustion device to be burnt to generate fume and steam, the fume and a part of the steam are sent into the drying device to serve as the drying media. The rest steam is sent into the pyrolysis device to provide the heat source for the pyrolysis. A chain conveying method and a method of chamber drying/discharge of the fume and the steam are adopted for the drying device. Two different steams with different temperatures are generated in the combustion device and used for drying and pyrolysis of the lignite respectively. Compared with the prior technology, the device and the method provided by the invention have the advantages of safe and reliable operation, reasonable design, steady running in the large-scale application, and capability of improving the comprehensive utilization rate of the lignite.

A data storage medium includes a substrate, a reflective metal layer, and a haze-prevention layer between the substrate and the reflective metal layer. The substrate includes an amorphous thermoplastic resin having a heat distortion temperature of at least about 140° C., a density less than 1.7 grams per milliliter, and an organic volatiles content less than 1,000 parts per million measured according to ASTM D4526. The haze-prevention layer includes a material having a volume resistivity of at least 1x10<-4 >ohm-centimeters and a tensile modulus of at least about 3x10<5 >pounds per square inch. The data storage medium resists hazing of the reflective layer at elevated temperatures.

A method and an apparatus (50) for producing direct reduced iron (37) from dry pellets (25) composed of iron oxide and carbonaceous material. A mixture of pellets (25) and free coke particles (38) with weight relation from 3:1 to 5:1 is fed into the top of an electrothermal fluidized bed (32) that is fluidized by nitrogen. By exposing pellets (25) in the electrothermal fluidized bed (32) to temperatures of between approximately 850-1,100° C. for an average period of between approximately 15-60 minutes, the volatiles are removed and the pellets (25) metallized. Reduced pellets (37) mixed with free coke (38) are discharged from the bottom of fluidized bed (32) and cooled. The reduced iron pellets (37) are physically separated from any free coke (38) and the free coke (38) is recycled back into the fluidized bed (32).

The invention provides a method for preparing high-purity beta elemene from natural plants containing the beta elemene such as curcuma zedoary (earthnuts or tubers of the curcuma zedoary), cedronella (fresh leaves of the cedronella), yellowtop (roots, stems, leaves, flowers and seeds of the yellowtop) and so on, which can improve the production efficiency from starting materials to the high-purity beta elemene and reduce production cost. Compared with the prior art, the method is mainly different in that the roots, stems, leaves, flowers and seeds of the natural plants are taken as raw materials; oleum volatile of specific parts of the natural plants is obtained by methods for extracting different oleum volatiles, and is distilled by molecular distillation method to remove compositions with high boiling points and non-volatile compositions; impurity compositions are removed by the ethanol extraction method and silver nitrate complex extraction method; and finally the beta elemene with the content between 95.0 and 99.9 percent is obtained through reduced pressure distillation or rectification. The bulk pharmaceutical chemicals not only can be prepared into oral dosing preparation such as emulsion oral liquid, self-emulsifying/ self-microemulsifying capsules, soft capsules and so on, but also can be prepared into non-alimentary dosing preparation such as emulsion injection, liquid drugs injection, transdermal absorbent, lung sprays, suppository and so on. The method has the advantages of novel design, concise operating steps, mild operating conditions and improvement of the production efficiency of the beta elemene.

The invention relates to a water-based macromolecule-isocyanate straw hard board and a preparation method thereof. Straws of rice, wheat, corn or other crops, a water-based macromolecule-isocyanate adhesive and a straw interface performance modifying agent are used as raw materials, and the straws are treated by section cutting, kneading and modification, adhesive application and heat pressing to produce the water-based macromolecule-isocyanate straw hard board. A mixture ratio of the absolute dry straws to the water-based macromolecule-isocyanate adhesive to the straw interface performance modifying agent by weight is 100 to 10-16 to 0.05-0.15. The straw hard board uses the water-based macromolecule-isocyanate adhesive to replace a pure isocyanate adhesive, radically improves the problems of toxic organic volatiles, poor prepressing performance, adhesion on boards, etc., remarkably reduces cost and really realizes green production, and the raw materials after the treatment of kneading and modification have good prepressing and molding performances and high one-off qualified rate. The water-based macromolecule-isocyanate straw hard board has the characteristics of unique design, long active period, excellent aging, water and heat resisting performances, simple operation, easy availability of equipment, no environmental pollution, easy implementation, etc., and produces huge entironmental, social and economical benefits after the water-based macromolecule-isocyanate straw hard board is popularized.
