The Longest Journey Begins With a Single Step: A Real Options Approach to Social Dilemmas
Collective action faces a public goods social dilemma where there exists an inherent tension between individual and collective interests. Considering the economic and social significance of public goods dilemmas, an important research question is why public goods dilemmas often result in collective …

Optimizing graphene oxide reduction via laser irradiation
The present report discusses a single step method to reduce graphene oxide via laser irradiation. A computer numerically controlled laser engraver equipped with a 450nm laser diode was engineered to conduct this research. Reduced graphene oxide samples were prepared on a polycarbonate substrate at …
