The unique properties of graphene have earned much interest in the fields of materials science and condensedmatter physics in recent years. However, the biological applications of graphene remain largely unexplored. In this study, we investigated the conditions and viability of a cell culture exposed to graphene onto glass and SiO 2/Si, using a human nerve cell line, SH-SY5Y. Cell viability was...

Let A be a Hausdorff space, <p a continuous mapping of A into itself. It is the purpose of the present paper to discuss various topics centering around the following question: If g is a bounded continuous function on A, does there exist a bounded continuous function/on A such that/(0a)— /(a) =g(a) for all a in At Suppose that for each «o in A, the set {<pna0, re2:0} is dense in A. Theorem 1 ass...

Bankers have a reputation for deviating from standard morals. It is an open question, though, if this claim can be substantiated. Here, it is tested directly if bankers respond differently to moral dilemmas. Evaluations of the moral acceptableness of behavioural options in two trolley cases by bankers (n = 23) are compared to those of ordinary people (n = 274). An apparent difference in respons...
