主讲人简介：
Dr. Yuri Lvov is a Professor of Chemistry, Tolbert Pipes Eminent Endowed Chair on Micro and Nanosystems and Associate Director of the Institute for Micromanufacturing, Louisiana Tech University. His area of specialization is nanotechnology including nanoassembly, bio/nanocomposites, nanoconstruction and clay nanotubes for controlled release. He was among pioneers of the polyelectrolyte layer-by-layer (LbL) assembly, a nanotechnology method which, after his first papers in 1993, followed by many thousands publications by researchers all over the world. He edited 4 books, published 9 book chapters, published more than 250 papers. Lvov’s total citation index is above 26 400 which is an outstanding result, and his h-index is 85. Lvov was awarded with prestigious international Alexander von Humboldt Prize in recognition of lifetime achievements in nano-scale chemistry in 2014, elected as a member of US National Academy of Inventors in 2015.

主讲内容：
This lecture is on nanoarchitectural strategy for clay nanotube self-assembly and core-shell metal mesocatalysts. A layer-by-layer (LbL) assembly of alternating layers of oppositely charged polyelectrolytes and nanoparticles provides the formation of 5-500 nm thick films with monolayers of various substances growing in a pre-set sequence on any substrates at a growth step of about 1 nm. This technology provides a novel method to fabricate functional nanocomposites.
本讲座主要先容粘土纳米管自组装及核壳金属催化剂纳米结构的修建要领。带差别电性的聚电解质和纳米粒子能够以每个办法1nm左右的效率在恣意基体外貌凭证预设的序列形成单分子层 ，通过这些单分子层交替层层自组装可制备5~500 nm的复合膜。该手艺为制备功效性纳米复合质料提供了一种新要领。
