This is a U.S.-Bulgarian cooperative research project that will focus on synthesizing large quantities of conductive nanoparticles for possible applications to battery technology. The principal investigators are Dr. Kenneth Klabunde from Kansas State University and Dr. Iovka Dragieva from the Central Laboratory of Electrochemical Power Sources in Sofia. The researchers will devise strategies for the synthesis of large quantities of conductive and semiconductive nanoparticies. The strategies will be based on two approaches: 1) modified sol-gel/aerogel procedures employing metal alkoxide molecular precursors leading to metal oxide nanoparticles, and conversation of metal oxide nanoparticles to metal sulfide (or selenide or telluride) nanoparticles by catalyzed solid-gas reactions and 2) borohydride reduction of mixed metal salts to yield bimetallic metal particles and metal hydrides, and metal vapor-solvent cocondensation to form nanocrystalline metals and bimetallics. Through this research the researchers expect to discover and develop better porous conducting materials for applications as electrodes in Li ion batteries, metal-hydride batteries, and zinc-air batteries.This project in materials research fulfills the program objectives of bringing together leading experts in the U.S. and Central/Eastern Europe to combine complementary efforts and capabilities in areas of strong mutual interest and competence on the basis of equality, reciprocity, and mutuality of benefit.

这是一个美国-保加利亚的合作研究项目，将集中于合成大量的导电纳米粒子，可能应用于电池技术。 主要研究人员是来自堪萨斯州立大学的Kenneth Klabunde博士和来自索菲亚电化学电源中心实验室的Iovka Dragieva博士。研究人员将设计大量导电和纳米颗粒的合成策略。 这些战略将基于两种办法：1）采用金属醇盐分子前体的改进的溶胶-凝胶/气凝胶程序，导致金属氧化物纳米颗粒，以及金属氧化物纳米颗粒转化为金属硫化物（或硒化物或碲化物）纳米颗粒，和2）混合金属盐的硼氢化物还原，以产生硒化金属颗粒和金属氧化物，以及金属蒸气-溶剂共缩合形成纳米晶金属和双金属。通过这项研究，研究人员希望发现和开发更好的多孔导电材料，用于锂离子电池，金属氢化物电池，和锌空气电池。这个材料研究项目实现了汇集美国和中央/地区领先专家的计划目标。- 东欧将在平等、互惠和互利的基础上，在具有强烈共同利益和能力的领域，将联合收割机的互补努力和能力结合起来。
