Although storminess is often cited as a driver of long-term coastal erosion, a lack of suitable datasets has only allowed objective assessment of this claim in a handful of case studies. This reduces our ability to understand and predict how the coas

The influence of the ionic character of a specific drug on its release rate from a hydrogel based on 2-hydroxyethylmethacrylate (HEMA) and acrylamide (AAm) is analyzed. The hydrogel was synthesized by photopolymerization employing visible light, safr

A hybrid epoxy composite was synthesized by adding halloysite nanotubes (HNTs) to an epoxy matrix toughened by an acrylic triblock copolymer (MAM). The morphology generated was composed of spherical MAM domains with sizes in the range of hundreds of

Tertiary amines are one of the typical catalysts used to accelerate transesterification reactions in epoxy vitrimers. Instead of adding a tertiary amine (e.g. tributylamine, TBA) to the initial formulation, secondary (e.g. dibutylamine, DBA) or prima

Epoxy vitrimers were synthesized employing stoichiometric amounts of diglycidyl ether of bisphenol A (DGEBA), sebacic acid (20% eq.) and an n-alkylamine, either octylamine (OA), dodecylamine (DA) or hexadecylamine (HA) (80% eq.). Apart from the chemi

Alkyl chains of β-hydroxyesters synthesized by the capping of terminal epoxy groups of diglycidylether of bisphenol A (DGEBA) with palmitic (C16), stearic (C18), or behenic (C22) fatty acids self-assemble forming a crystalline phase. Above a particu

Director interlocks, which occur when companies have directors in common, have concerned shareholders, the public and legislators since the early 1900s. The purpose of this paper is to analyse the interlocking directorships of the Top 40 companies li
