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 - 巴尔加里的合作研究项目，它将着重于合成大量导电纳米颗粒，以用于电池技术。 首席研究人员是堪萨斯州立大学的肯尼斯·克兰本德（Kenneth Klabunde）和索非亚电化学中央实验室的Iovka Dragieva博士。研究人员将制定策略来综合大量导电和半导性纳米官方。 这些策略将基于两种方法：1）使用金属烷氧化物分子前体进行了修改的溶胶 - 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的对话与金属硫化物（或硒化合物或泰氏尿素）纳米粒子通过催化的固体固体胶片（或者）反应和2）混合金属盐的硼氢化物还原以产生双金属金属颗粒和金属氢化物，以及金属蒸气 - 溶剂 - 溶剂固定以形成纳米晶金属和双金属。通过这项研究，研究人员期望发现并开发更好的多孔导电材料，以应用于电池中的电极，金属氢电池和锌 - 空气电池。这项材料研究中的项目实现了将领先专家聚集在一起的计划目标。美国和中欧将根据平等，互惠和利益共同的互补性和能力结合互补的努力和能力。
