报告介绍 We will report an overview on the self-assembly in water of amphiphilic block copolymers into polymersomes, and their applications in loading and controlled release of both hydrophilic and hydrophobic molecules and biomolecules. We will pay special attention to polysaccharide and polypeptide-based block copolymer vesicles that we have studied these recent years in our group. These newly developed co...

报告介绍 报告摘要：We have been working for several years to develop robust solution-based routes to the synthesis of nanocrystals and nanowires of many different semiconductors and metals. The general concept we pursue is to synthesize nanomaterials with unique size-tunable optical, electronic and optoelectronic properties and then manipulate them like building blocks into devices and structures with the po...

报告介绍 Abstract： In nuclear reactors, neutron or proton irradiation can generate damage as high as a few hundred displacements per atom (dpa) over the years. The primary radiation damage event in metals is displacement of atoms and the consequent formation of Frenkel (vacancy-interstitial) pairs and various aggregates of defects such as interstitial loops, voids, He bubbles and stacking fault tetrahedra. ...

报告介绍 Abstract：The talk focuses on the group research efforts on various nanostructured functional oxide thin films for high temperature superconductors (HTS), solid oxide fuel cells, ferroelectrics, transparent conducting oxides and others. Wires that carry electrical current without resistance are fabricated by coating metal substrates with the HTS YBa2Cu3O7-δ (YBCO). Using nanolayer architecture...

报告介绍 Abstract:Three-dimensional (3D) topological insulators (TIs) represent a new state of quantum matter with a bulk gap generated by the spin-orbit interaction and an odd number of relativistic Dirac fermions on the surface. The unusual surface states of TIs can be the host for many striking quantum phenomena, such as an image magnetic monopole induced by an electric charge and Majorana fermions induce...

报告介绍 Abstract:Contact mechanics between elastic solids with random surface roughness is the basis for understanding a huge number of phenomenon in nature and technology. In my presentation I will describe a novel theory for contact between solids with surface roughness on many length scales (typically fractal-like surfaces) which has been found to be remarkable accurate and flexible, and which can be app...

报告介绍 内容摘要：Topological states of matter support quasiparticle excitations with fractional charge and possibly exotic statistics of the non-Abelian type, known as non-Abelian anyons. Current experimental attempts to reveal such exotic statistics focus on interference involving edge transport. In this talk we will discuss how one can reveal the non-Abelian statistics in bulk probes. We show that bulk t...

报告介绍 报告摘要:The presentation focuses on developments of cost effective solar cells currently conducted in Qiao group, including dye-sensitized solar cells (DSCs) and polymer solar cells (PSCs). In DSCs, carbon nanofibers are used as a low cost alternative to Pt counter electrode and achieved comparable cell performance at a lower cost, also TiO2 nanofiber/nanoparticle composite is used as an innovative...

报告介绍 报告摘要:The advance of electronics and photonics in the last several decades has greatly enriched our lives and revolutionized the modern society. To develop next-generation electronics and photonics with enhanced and/or new functionalities, nanostructured electronic materials, including both organic and inorganic as well as their hybrids, have received great attention. Organic electronic materials...
