Advanced Porous Materials for Maritime Carbon Capture

open access: yesAdvanced Materials, EarlyView.
Carbon capture from emission sources, such as marine vessels, has attracted significant attention over the years. To achieve this goal, sorbents such as metal–organic frameworks (MOFs), porous polymer networks (PPNs), covalent organic frameworks (COFs), and their post‐synthetic modifications are currently being explored.

Economic Freedom and Economic Crisis [PDF]

open access: yesSSRN Electronic Journal, 2014
AbstractIn this paper, I explore the politically contested association between the degree of capitalism, captured by measures of economic freedom, and the risk and characteristics of economic crises. After offering some brief theoretical considerations, I estimate the effects of economic freedom on crisis risk in the post-Cold War period 1993–2010.
