Master Nanoscience and Nanotechnology
The development of fundamental understanding in material science starts at the atomic level, where concerted movements set the properties of a material and its reaction upon the application of external factors. With the current development of nano-structured materials as e.g. metal-organic frameworks which can be used for energy storage applications, gaining insights into the dynamics that driv...
متن کاملNanoscience, nanotechnology, and modeling
nanotechnology are currently quite popular in both the scientific and the general press. These intermediate-length structures are intriguing because generally in the nanometer region, almost all physical and chemical properties of systems become size-dependent. For example, although the color of a piece of gold remains golden as it reduces from inches to millimeters to microns, the color change...

WE are all aware of the use of ultrasound radiation in medicine, where it is being used mostly for diagnosis, and where more recently, focused ultrasound radiation is being used to destroy cancer cells. Less is known of its application in chemistry, despite the fact that it has applications across almost the entire breadth of that field. One of the main advantages in conducting sonochemical exp...

Development of synthesis protocols for realizing nanomaterials over a range of sizes, shapes and chemical compositions is an important aspect of nanotechnology. A number of recipes have been developed for the synthesis of metal nanoparticles in polar (for example, water) and non-polar organic solvents, each method accompanied by characteristic advantages and disadvantages. Specific applications...
متن کاملSpecial Section: Nanoscience and Nanotechnology
Current status of nanoscience research is briefly surveyed with special emphasis on monodisperse metal nanocrystals. Tunneling spectroscopy measurements on polymer protected magic nuclearity Pd561 nanocrystals have revealed single electron charging effects. Mesoscopic organizations resulting from self-assembly of these nanocrystals have been investigated. Giant clusters containing magic numbers...
