Viable Methodologies for the Synthesis of High-Quality Nanostructures

The development of environmentally benign methods for the synthesis of nanomaterials has become increasingly relevant as chemists look to shape a more sustainable future. In this review, we present current work towards developing alternative methods for synthesizing a wide range of high-quality nanomaterials with predictable and controllable size, shape, composition, morphology, and crystallinity. In particular, we focus on the inherent advantages of utilizing porous membrane templates, ultrasonic and microwave irradiation, alternative solvent systems, as well as biologically inspired reagents as reasonably cost-effective, socially responsible methods to generate metal, metal oxide, fluoride, sulfide, selenide, and phosphate nanomaterials

Structure and dynamics of water, electrolyte solution and solid/liquid interfaces - a molecular simulation study ?

The microscopic understanding of solid/liquid interfaces leads to the macroscopic understanding of physical and chemical properties, such as friction, lubrication, the power density of batteries and the activity of catalysis. However, several important problems remain to be solved before a discussion can begin on such interface-related phenomena. For example, we have not obtained enough knowledge of the so-called 'structuring of water' at the interfacial region nor a microscopic picture of a bulk electrolyte solution.

In this talk, structure and dynamics of bulk pure water, a few types of electrolyte solutions, and simple solid/liquid interfaces will be revealed based on combination of the first-principles and classical molecular dynamics simulations. In order to discuss the higher-order structure of a hydrogen-bond network, an analysis method focusing on the ring-shape structure of hydrogen bonds will also be proposed.
