“…In their works, some of which were written expressly to entertain the emperors in their visits to the old Greek cities, the Second Sophistic authors chose highly esoteric themes, often both arcane and archaistic. They set their recitations in the pre-Roman Greek world (Kennedy 1974: 17-22, Bowie 1970. The specific subjects were often obscure and the language cultivated for the formal presentations was Attic Greek of the fifth and forth centuries B.C.…”

RESUMO: O artigo visa demonstrar como a entrada romana do século II d.C. da cidade de Perge, na Ásia Menor, pertence a um conjunto arquitetônico harmônico, construído a partir de um programa artístico mais amplo. Assim, os vários elementos que compõem esta entrada (pátios, nichos e esculturas, colunadas) são analisados à luz de suas possíveis associações com os estilos de pintura mural e de composições literárias, adquirindo uma coerên cia única. UNITERMOS: Arte romana-Arte provincial-Arquitetura romana na Ásia Menor.

“…CSM rubber is known for its resistance toward chemicals, ultraviolet, and high temperature. [ 4–6 ] Maleic anhydride–grafted ethylene–propylene (M‐EPM) elastomer is commercially available under the brand name of Keltan 1519R by ARLANXEO, Germany. The peroxide‐initiated free‐radical grafting of maleic anhydride (MA) onto saturated polymers has been commercially established.…”

Ionic thermoplastic elastomer (TPE) materials have substantial scientific and commercial value due to their recyclable nature and wide adaptive applications. This article presents experimental results and analysis on the effects of the addition of “zwitterionic component” on various properties of maleic anhydride–grafted ethylene–propylene (M‐EPM)–based ionic TPEs. For this purpose, L‐lysine amino acid has been used, which contains a zwitterionic group and a primary amine group. The present work aims to understand how zwitterionic compounds can influence the behavior of the typical ionic TPEs. In this work, a reference ionic TPE sample and different test batches were prepared by varying the dosage of lysine amino acid in the rubber compound. Samples were easily prepared by using conventional rubber processing equipment, such as an internal mixer, two‐roll mill, and hydraulic press. Mechanical and other physical properties were investigated to examine the ionic cluster formation assisted by lysine amino acid. Adverse and favorable aspects of using lysine amino acid in zinc‐based M‐EPM ionic TPE have been discussed comprehensively.

“…Many of the grafting processes have been commercially established and practiced for decades . These grafting processes are often carried out to cater to the requirements of special applications. − For instance, chlorosulfonated polyethylene (CSM or Hypalon rubber) is produced by chlorosulfonation of polyethylene in a solution of chlorinated hydrocarbons, chlorine, and sulfur oxide. CSM rubber is known for its resistance toward chemicals, UV, and high temperature .…”

Herein, we report a network of maleic anhydride-grafted ethylene propylene rubber (M-EPM) cross-linked by the coordination complexes that combines high tensile strength, high stretchability, and reprocessability aspects. At appropriate temperatures, coordination cross-linked M-EPM rubber can be easily reprocessed without compromising physical properties. At first, we demonstrate the synthesis and characterization of coordination complexes of two types of amino acids, that is, l-lysine and l-tryptophan, which form a complex with Cu(II) ion through their respective amino acid group. As followed by various analyses, these complexes of l-lysine and l-tryptophan exhibit a distinct behavior after incorporation into M-EPM rubber. The copper–ligand bonds can easily break and reform, while the copper center remains attached to the amino acid ligands through a stronger interaction with the carboxylic group, which enables the highly dynamic stress-induced ion exchange process. This notion is firmly endorsed by the enhanced physicomechanical attributes of M-EPM rubber and the recyclability aspect.
