Nanostructured Bitumen with Nanocarbon
Eurasian Chemico-Technological Journal, 2019 Physical and chemical indicators of bitumen quality of grade BND 70/100 with the added carbon nanopowder 2% by weight have been studied by laboratory test methods and analysis. High reaction ability of nanopowder particles and concentration of excess surface and internal energy in them have been determined, which provide the increase of low-temperature

European Journal of Science, Innovation and Technology, 2022 The ageing of asphalt and the associated changes in its performance are largely due to the ageing binder it contains. Ageing makes bitumen harder and more brittle. The hardening and embrittlement of the binder has a direct effect on the performance characteristics of the asphalt.

Journal of the Royal Anthropological Institute, EarlyView.Recent archaeological discoveries, reviewed in this essay, challenge traditional views on the emergence of human symbolic cognition. Once believed to have originated in Europe around 40,000 years ago, new evidence shows it emerged much earlier across diverse regions.

Genesis of solid bitumen [PDF]
Scientific Reports, 2020 AbstractThis paper presents a new schematic model for generation and timing of multiple phases of solid bitumen throughout the continuum of organic matter maturation in source and tight reservoir rocks. Five distinct stages in the evolution of solid bitumen are proposed: (1) diagenetic solid bitumen (or degraded bituminite), which is not a secondary ...

A Newly Discovered Tablet‐Making Facility in Nineveh: Insights From Scientific Analysis
Archaeometry, EarlyView.ABSTRACT This paper addresses the question of tablet technology in the Neo‐Assyrian capital city of Nineveh. Recent excavations in the lower town of Nineveh by the Iraqi–Italian Archaeological Expedition uncovered an exceptional assemblage of more than 200 tablets from an elite residence that appears to have included a scriptorium.
