Procedural aspects concerning maritime law

Along this work we wish to highlight the main influence of Procedural Law in some as-pects in our Maritime Law. Our point of view has been supported by new Maritime Naviga-tion Act of 2014, when including the Title X ruling "Procedures Specialities in Maritime Navigation". We are focusing on the Bill of Lading as an essential document in maritime shipping from a procedural point of view. It is particulary relevant the express recognition of its enforce-able nature through the Spanish Maritime Navigation Act, giving to the bill of lading the consideration as an true extrajudicial enforceable title. We will point out the main error of the spanish regulator in the new Maritime Navigation Act, when repeating the provided posibility in the Spanish Civil Procedure Act, of a direct procedure of execution grounded on a extrajuditial enforcement such as the bill of lading. Finally, we would like to conclude the work studying the possible uses of Small Claim Procedure of the 812 article and followings of Spanish Civil Procedure Law, for the pur-pose of safeguarding credit, so as a short mention to other procedural figures expressly in-cluded in the Title IX of Maritime Navigation Law.

Ammonia effects on proton conductivity properties of coordination polymers

Crystalline metal phosphonates are referred to as a type of structurally versatile coordination polymers [1]. Many of them contain guest molecules (H2O, heterocyclics, etc.), acidic sites and, furthermore, their structure can be also amenable for post‐synthesis modifications in order to enhance desired properties [2]. In the present work, we examine the relationships between crystal structure and proton conductivity for several metal phosphonates derive from multifunctional ligands, such as 5-(dihydroxyphosphoryl)isophthalic acid (PiPhtA) [3] and 2-hydroxyphosphonoacetic acid (H3HPAA). Crystalline divalent metal derivatives show a great structural diversity, from 1D to 3D open-frameworks, possessing hydrogen-bonded water molecules and acid groups. These solids present a proton conductivity range between 7.2·10-6 and 1.3·10−3 S·cm-1. Upon exposure to ammonia vapor, from an aqueous solution, solid state transformations are observed accompanied of enhance proton conductivities. The stability of these solids under different environment conditions (temperature and relative humidities) as well as the influence of the ammonia adsorption on the proton conduction properties of the resulting solids will be discussed.
