Nanosystem processes

Thus, the spatial-energy notions given allow characterizing in general the directedness of the process of carbon nanosystem formation. 

In nonequilibrium steady states, the mean currents crossing the system depend on the nonequilibrium constraints given by the affinities or thermodynamic forces which vanish at equihbrium. Accordingly, the mean currents can be expanded in powers of the affinities around the equilibrium state. Many nonequilibrium processes are in the linear regime studied since Onsager classical work [7]. However, chemical reactions are known to involve the nonlinear regime. This is also the case for nanosystems such as the molecular motors as recently shown [66]. In the nonlinear regime, the mean currents depend on powers of the affinities so that it is necessary to consider the full Taylor expansion of the currents on the affinities ...

If one accepts the premise that self-assembly will be an important component of the formation of nanomaterials, it is clearly important to understand it as a process (or, better, class of processes). The fundamental thermodynamics, kinetics, and mechanisms of self-assembly are surprisingly poorly understood. The basic thermodynamic principles derived for molecules may be significantly different for those that apply (or do not apply) to nanostructures the numbers of particles involved may be small the relative influence of thermal motion, gravity, and capillary interactions may be different the time required to reach equilibrium may be sufficiently long that equilibrium is not easily achieved (or never reached) the processes that determine the rates of processes influencing many nanosystems are not defined. 

The physical sense of this expressions is quite transparent, they describe the quantum amplitudes of the scattering processes. Three functions scattering state in the Landauer-Biittiker theory. Note, that G here is the full GF of the nanosystem including the lead self-energies.

Extending the current state of knowledge could involve measurements at high temperature with shock experiments to access transition pressures closer to the thermodynamic limit. Progress is currently being made to study the transition in individual nanocrystal particles, to both eliminate the ensemble statistics and allow for individual transitions to be observed on -femtosecond time scales. The study of nanocrystal solid-solid phase transitions to oxide nanosystems should also prove to be useful in understanding the microscopic process of solid-solid transitions relevant to geophysically important systems. 

Obtaining insight into charge transfer processes is important in order to improve the photoconversion efficiencies in semiconductor-based nanoassemblies. The principles and mechanism of photocatalytic reactions in advanced oxidation processes can be found in earlier review articles [40-42]. Technological advances in this area have already led to the product development for a variety of day-to-day operations. Commercialization of products such as self-cleaning glass, disinfectant tiles and filters for air purification demonstrate the initial success of nanosystems for environmental applications [43]. 

Nanopharmacy, or pharmaceutical nanotechnology, comprises, but is not limited to, the topics shown in Scheme 2. These encompass the manipulation and processing of nanosystems in the 2 nm-150 nm size range, their physicochemical characterization, applications and biological evaluation. 

Particle size may be directly or indirectly implicated in all the areas shown in Figure 5. For example, the relationship between diffusion coefficient and radius is a directly inverse one drug release, which is surface area related, is dependent on the erosion process in some nanosystems. 

Nanosystem design and application as fundamental principles and tools to measure and image the biological processes of health and disease, and methods to assemble nanosystems. 

Given the success of our approach in designing experimentally viable nanomaterials, we believe that the coming years would see the use of this approach in the development of novel nanosystems with potential applications in pharmaceuticals, optics, opto-electronics, information storage, sensors, biotechnology, nanomedicine, nanofluidics, and nanoelectronics. Furthermore, it would also provide vital information on the methods needed to harness these nanosystems as machines and devices and provide an increased understanding of the science behind most nanoscale processes.
