Asymmetric transformation of achiral gold nanoclusters with negative nonlinear dependence between chiroptical activity and enantiomeric excess

open access: yesNature Communications, 2023
The investigation of chirality at the nanoscale is important to bridge the gap between molecular and macroscopic chirality. Atomically precise metal nanoclusters provide an ideal platform for this research, while their enantiopure preparation poses a ...

Neutrosophic hybrid structures and neutrosophic hybrid matrices

open access: yesNeutrosophic Sets and Systems, 2023
Motivated by the theory of hybrid structures, our aim in this paper is to introduce the notion of hybrid matrices and bring out an application. Some operations on hybrid matrices are discussed. The notion of hybrid matrices is then generalized by introducing the novel idea of neutrosophic hybrid matrices.

Delay-dependent robust stability of stochastic delay systems with Markovian switching [PDF]

open access: yes, 2009
In recent years, stability of hybrid stochastic delay systems, one of the important issues in the study of stochastic systems, has received considerable attention. However, the existing results do not deal with the structure of the diffusion but estimate
