Book chapter (peer-reviewed)abstract
- In this chapter, the effect of edge passivated by hydrogen on the electronic and transport properties of the molecular devices of finite-size metallic carbon nanotubes (CNTs) is investigated by using density-functional theory in combination with Green's function method. Three types of hydrogenations are considered for the edge carbon atoms at the two open ends of the CNTs. The calculated energy gap between the highest occupied and the lowest unoccupied molecular orbitals decreases with increasing the length of the CNTs for the three hydrogen-passivated cases, respectively. Nonlinear current-voltage (I-V) curves and quantum conductance have been obtained in all junctions. It is shown that the electronic properties of the finite-size CNTs and the transport properties are sensitive to the passivation types of edge. With increasing the hydrogen passivation concentration of edge carbon atoms, it is indicated that the I-V characteristics have obviously the widening of bandgap and the decreasing of the quantum conductance.

Photoluminescence

In: Spectroscopy of Semiconductors. - Cham : Springer. - 9783319949529 - 9783319949536 ; , s. 107-158
-
Book chapter (peer-reviewed)abstract
- Quantum mechanics theory about photoluminescence is first introduced then applied to various case studies to understand the microscopic processes, namely photon excitation, energy relaxation and radiative recombination, involved in the photoluminescence spectroscopy in semiconductor structures ranging from bulk to nanoscale. The study is further deepened by analyzing the photoluminescence spectra of quantum dots under the multiphoton excitation.

Nutrigenetics of type 2 diabetes

Book chapter (peer-reviewed)abstract
- Type 2 diabetes has become a leading health problem throughout the world. The escalating epidemic of type 2 diabetes is believed to result from a collision between inherent biological susceptibilities (genotypes) and a shift toward dietary habits and lifestyle that promote obesity over the past several decades; the transition from "traditional" to modern "obesogenic" lifestyles is characterized by widespread access to highly palatable, nutrient-deficient, and calorie-dense foods and beverages, as well as circumstances that promote sedentary behaviors and inhibit physical activity. In the past decades, a large body of epidemiological studies has associated various dietary factors with type 2 diabetes risk. In the meantime, genetic studies have made great strides in unraveling the genetic basis of type 2 diabetes by identifying more about 100 common genetic loci related to the disease. Nutrigenetics, a relatively new branch of nutrition science, focuses on determining the interplay between dietary exposures and genetic factors in the etiology of many diseases including type 2 diabetes. Even with many hundreds of gene-diet/lifestyle interaction studies on diabetes-related traits published over the past two decades, few examples have been adequately replicated or validated. By contrast, a number of replicated examples of interactions between lifestyle factors (e.g., consumption of sugar sweetened beverages and fried foods and low physical activity and sedentary lifestyles) and genetic factors in obesity (a major risk factor for diabetes) have recently emerged. Further advances are likely to come from the optimization of methods and study designs for nutrigenetic analyses. The development of methods to integrate genetic, transcriptomic, epigenomic, proteomic, and metabolomic data to help define the functional mechanisms that might underlie observations of gene-lifestyle interactions is an especially exciting, yet challenging, area. Nutrigenetic studies hold great promise to inform personalized diet and lifestyle interventions to reduce type 2 diabetes risk and improve human health; however, deriving replicated examples of such interactions and determining how best to translate these findings into public health practice and medical intervention remain major challenges.
