    • A method, system and apparatus for plasma blasting comprises a solid object having a borehole, a blast probe comprising a high voltage electrode and a ground electrode separated by a dielectric separator, wherein the high voltage electrode and the dielectric separator constitute an adjustable probe tip, and an adjustment unit coupled to the adjustable probe tip, wherein the adjustment unit is configured to selectively extend or retract the adjustable probe tip relative to the ground electrode and a blasting media, wherein at least a portion of the high voltage electrode and the ground electrode are submerged in the blast media. The blasting media comprises a thixotropic or electro-rheological fluid. The adjustable tip permits fine-tuning of the blast. The property of instantaneous high viscosity of thixotropic and electro-rheological fluids is advantageously used to seal the cavity containing the blasting probe thereby increasing the blasting pressure making the whole system more efficient.

    • Antennas using nonwoven geotextiles with embedded metallic or other wave carrying fibers are described herein. The geotextiles antennas are designed to be an internal, integral part of the nation's infrastructure. Geotextile antennas are flexible and easily conform to natural and manmade surfaces such as exterior building surfaces, for example, roads, roofs and bridges. Geotextile antennas are considerably less vulnerable to damage and probably much less expensive than the current, highly vulnerable and costly cell towers. In particular, geotextiles used in roads are especially well protected by the asphalt pavement above. The fabric-based conformal antenna enhances the usefulness and reliability of the communication infrastructure which is exceedingly vulnerable to vandalism, terrorism and natural disasters.

    • The present invention relates to a method for conversion of biomass to biochar in subcritical water at 230-350° C. and 500-3000 psi. Under subcritical water conditions, biomass readily converts into biochar, biocrude, and some gases. In this invention, yield of biochar is significantly improved by recycling of biocrude. The process can produce hydrophobic biochar that has at least 70 wt % (dry basis) carbon as opposed to ˜25 wt % carbon in hydrophilic biomass, and has a heating value of about 29 MJ/kg (HHV-dry basis) which is comparable to good quality coals. More than 90% energy of biomass is retained in the biochar. The invention provides an effective means to convert biomass into a high energy density fuel for use in a variety of applications.
    • 本发明涉及在230-350℃和500-3000psi的亚临界水中将生物质转化为生物炭的方法。 在亚临界水条件下,生物质很容易转化为生物炭,生物质和一些气体。 在本发明中,生物炭的产率通过生物粗制品的回收显着提高。 该方法可以生产具有至少70重量%(干基)碳的疏水性生物炭,而亲水生物质中的碳含量为〜25重量%,并且具有约29MJ / kg(HHV-干基)的热值,这相当于 到优质煤。 生物炭中保留了90%以上的生物质能。 本发明提供了将生物质转化成用于各种应用的高能量密度燃料的有效手段。

    • A stabilized, chemically reactive, metallic nano-material effective for degradation of chlorinated organic compounds in soils, sediments and groundwater. The nano-material is composed of a magnetic metal nanoparticle and a carbohydrate stabilizer bound to the nanoparticle. The preferred metal nanoparticle is iron and the preferred carbohydrate stabilizer is either a starch or a water soluble cellulose such as sodium carboxymethyl cellulose. The nanoparticle may be either mono-metallic, bi-metallic or multi-metallic in nature, but is preferably bi-metallic wherein it is coated with a secondary catalytic metal coating, preferably palladium. A method of making the metallic nano-material is further disclosed wherein a solution of the metal nanoparticle and carbohydrate stabilizer is prepared, and the nanoparticle is then reduced under inert conditions. A process for reductive dechlorination of chlorinated organic compounds is also disclosed wherein the reduced magnetic metal nanoparticle is prepared, and then contacted with a chlorinated organic compound to dechlorinate the compound. Preferably, the nano-material is injected into a site such as soil subsurface or groundwater contaminated with a chlorinated organic compound to provide in-situ dechlorination.
