    摘要： Metallic nanoparticles and processes for forming metallic nanoparticles. In one aspect, the invention is to a process for forming nanoparticles comprising the step of heating a solution comprising a first metal precursor and a nucleating agent (e.g., nucleate nanoparticles or a nucleate precursor) in the presence of a base under conditions effective to form the nanoparticles. The first metal precursor preferably comprises a cationic metal species having a low reduction potential. The invention is also to a nanoparticle or plurality of nanoparticles, each nanoparticle comprising a core having a largest dimension less than about 10 nm; and a metal layer substantially surrounding the core and having a largest dimension less than about 200 nm.

    摘要： The invention is to printed resistors and processes for forming same. The resistors comprise a conductive phase, preferably comprising conductive nanoparticles, and a resistive phase. In the processes of the invention, a resistor may be formed from a single ink or a plurality of inks. In the single ink embodiment, an ink is deposited which comprises a conductive phase precursor, a resistive phase precursor and a vehicle. The vehicle in removed and the conductive and resistive phase precursors are converted to a conductive phase and a resistive phase, respectively. In the multiple ink embodiment, a first ink comprising the conductive phase precursor and a first vehicle and a second ink comprising the resistive phase precursor and a second vehicle are deposited on the substrate. The vehicles are removed and the conductive and resistive phase precursors are converted to a conductive phase and a resistive phase, respectively.

    摘要： A DC block with a band-notch characteristic using a defected ground structure (DGS), includes a pair of coupled lines for being formed parallel to each other on one surface of a dielectric and blocking a flow of a DC, and at least one DGS for being formed on an area of the rear surface of the dielectric corresponding to each coupled line and comprising an etched region formed by etching a part of a ground surface bonded to the dielectric and a metal region formed in the etched region. Accordingly, the stop band of the desired bandwidth in the desired communications band can be formed and the size of the communications system can be reduced.
