In the past decade, polymer electrolyte membrane fuels (PEMFCs) have been evaluated for both automotive and stationary applications. One of the main obstacles for large scale commercialization of this technology is related to the sluggish oxygen reduction reaction that takes place on the cathode side of fuel cell. Consequently, ongoing research efforts are focused on the design of cathode materials that could improve the kinetics and durability. Majority of these efforts rely on novel synthetic approaches that provide control over the structure, size, shape and composition of catalytically active materials. This article highlights the most recent advances that have been made to tailor critical parameters of the nanoscale materials in order to achieve more efficient performance of the oxygen reduction reaction (ORR).

Abstract: This paper explores policy choices made in the governance of forest resources in Lithuania during the period of 1990–2005. The present system of governance of forest resources in Lithuania is compared with a theoretical framework for good governance. In addition, the reforms in the governance model in Lithuania are placed in the context of forest governance in other countries of the region. The results of the study indicate that Lithuanian forestry has evolved from hierarchical and extreme state interventionist governance to relatively transparent and accountable governance that respects private ownership, is sensitive to the public needs and interests as well as demand and supply in the market. The results of our work have indicated that the privatization has served as the main impetus for change. On a larger scale, the reforms of the forest sector in the three Baltic States seem to have progressed in a more similar manner than compared to those in Poland, Russia, and Ukraine.
