An ab initio study of hydroxylated graphane
No full textGraphene-based derivatives with covalent functionalization and well-defined stoichiometry are highly desirable in view of their application as functional surfaces. Here, we have evaluated by ab initio calculations the energy of formation and the phase diagram of hydroxylated graphane structures, i.e., fully functionalized graphene derivatives coordinated with -H and -OH groups. We compared these structures to different hydrogenated and non-hydrogenated graphene oxide derivatives, with high level of epoxide and hydroxyl groups functionalization. Based on our calculations, stable phases of hydroxylated graphane with low and high contents of hydrogen are demonstrated for high oxygen and hydrogen partial pressure, respectively. Stable phases of graphene oxide with a mixed carbon hybridization are also found. Notably, the synthesis of hydroxylated graphane has been recently reported in the literature. © 2017 Author(s)

Towards Ethical Risk Assessment of Symbiotic AI Systems with Fuzzy Rules
No full textArtificial Intelligence (AI) based systems are expanding rapidly in all domains of life. They are entering our everyday life and performing tasks on our behalf. AI-based systems such as personal healthcare assistants are increasingly engaging in close symbiotic relationships with humans. Symbiotic AI (SAI) promises improved outcomes in various domains such as healthcare, education, and business. However, as the degree of symbiosis increases, so does the ethical risk. To ensure that these systems behave ethically and do not cause harm of any kind (physical, mental, violation of privacy, etc.), we need to find ways to assess the ethical risk (risk of causing harm), then choose the right action to mitigate that risk. In this work, we propose an approach based on fuzzy logic for ethical risk assessment (ERA) of SAI systems. The approach is illustrated by means of a case study taken from the healthcare domain
Interface of graphane with copper : a van der Waals density-functional study
No full textVarious forms of hydrogenated graphene have been produced to date by several groups, while the synthesis of pure graphane has not been achieved yet. The study of the interface between graphane, in all its possible hydrogenation configurations, and catalyst metal surfaces can be pivotal to assess the feasibility of direct CVD growth methods for this material. We investigated the adhesion of graphane to a Cu(111) surface by adopting the vdW-DF2-C09 exchange-correlation functional, which is able to describe dispersion forces. The results are further compared with the PBE and the LDA exchange-correlation functionals. We calculated the most stable geometrical configurations of the slab/graphane interface and evaluated how graphane's geometrical parameters are modified. We show that dispersion forces play an important role in the slab/graphane adhesion. Band structure calculations demonstrated that in the presence of the interaction with copper, the band gap of graphane is not only preserved, but also enlarged, and this increase can be attributed to the electronic charge accumulated at the interface. We calculated a substantial energy barrier at the interface, suggesting that CVD graphane films might act as reliable and stable insulating thin coatings, or also be used to form compound layers in conjunction with metals and semiconductors
Rethinking Bias and Fairness in AI Through the Lens of Gender Studies
No full textThis paper examines the main approaches that have been put forth to contrast the emergence of biases in AI systems, namely causal, counterfactual reasoning, and constructivist methodology. The objective is to demonstrate the necessity of supplementing this technical solution with a more comprehensive social analysis of the genesis of discriminatory practices. To investigate this sphere, we leverage results from the field of Gender Studies. In particular, we apply the theory of gender performativity as theorized by Judith Butler. This illustrates how AI functions within the social fabric, manifesting patriarchal configurations of gender through an analysis of the notorious case of the COMPAS system for predictive justice. This approach enables an expansion of the interpretation of the concept of fairness, thereby reflecting the complex dynamics of gender production. In conclusion, the gender dimension needs to be reconsidered not as an individual feature but as a performative process. Moreover, it enables the identification of pivotal issues that must be addressed during the design, development, testing, and evaluation phases of AI systems
Effects of the substrate on graphone magnetism: A density functional theory study
No full textThe magnetism of graphone, a single-side-hydrogenated graphene derivative, has been related to the localized and unpaired p-electrons associated with the unhydrogenated carbon atoms. In the present density functional theory study, the effects the adhesion to either Cu(111) or α-quartz (0001) surface on the magnetic properties of graphone have been investigated. The total magnetization of the graphone adsorbed to copper and quartz surface is reduced by four and two times, respectively, with respect to the isolated graphone. We have shown there is electronic charge transfer from surface towards three-fold coordinated C atoms of graphone, but the main role in the partial magnetism quenching is played by bond formation and the consequent electron pairing of p-electrons. The critical temperature has been investigated on the basis of the mean field theory to evaluate the stability of the magnetism at ordinary temperature. © 2015 Elsevier B.V. All rights reserved
