Dai, W. and Zhong, Q., 2019. Spatial Organization and Location Choices of Marine Firm: A Value Chain Based Analysis. In: Gong, D.; Zhu, H., and Liu, R. (eds.), Selected Topics in Coastal Research: Engineering, Industry, Economy, and Sustainable Development. Journal of Coastal Research, Special Issue No. 94, pp. 653–658. Coconut Creek (Florida), ISSN 0749-0208. This paper explores the impact of external agglomerations and internal agglomerations based on geographically bounded on marine firms' location strategies. This paper considers all activities in the value chain and allows location choices to vary by research and development, manufacturing and sales, and using data from Longitudinal Business Database and corporate research, the location decision of a newly established maritime logistics company in a country from 1999 to 2009 is analyzed. Empirical analysis indicates that, one side, the utility brought by the industries location increases with the improvement of the accessibility to the port, to the raw material suppliers and to the product markets, but declines with the rise in the land price and the labor cost. On the other side, the demand of the proximity to port is driven by the desire to decline the transport cost, demonstrating in the reduction of the transport cost for raw materials and products by shipping and moving nearer to the places which have great demand for the products.

Conductive metal-organic frameworks (c-MOFs) and ionic liquids (ILs) have emerged as auspicious combinations for high-performance supercapacitors. However, the nanoconfinement from c-MOFs and high viscosity of ILs slow down the charging process. This hindrance can, however, be resolved by adding solvent. Here, constant-potential molecular simulations are performed to scrutinize the solvent impact on charge storage and charging dynamics of MOF-IL-based supercapacitors. Conditions for >100% enhancement in capacity and ≈6 times increase in charging speed are found. These improvements are confirmed by synthesizing near-ideal c-MOFs and developing multiscale models linking molecular simulations to electrochemical measurements. Fundamentally, the findings elucidate that the solvent acts as an "ionophobic agent" to induce a substantial enhancement in charge storage, and as an "ion traffic police" to eliminate convoluted counterion and co-ion motion paths and create two distinct ion transport highways to accelerate charging dynamics. This work paves the way for the optimal design of MOF supercapacitors., (© 2024 Wiley‐VCH GmbH.)
