Glimpses of the Third Millennium BC in the Carpathian Basin [PDF]

, 2013
The relative and absolute chronology of the cultural groups of the 3rd millennium BC is a particularly exciting field of prehistoric research because this period spans the assumed boundary of two major periods — the final phase of the Copper Age and ...

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

Advanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Friuli between Late Copper Age and Early Bronze Age

Traces in Time, 2015
The period commonly referredas Eneolithic or Copper Age is currently poorly documented in Friuli (Borgna et al. 2011). In particular, features that can be clearly related to the Bell Beaker culture appear to be entirely absent.

Slab Grave expansion disrupted long co-existence of distinct Bronze Age herders in central Mongolia

Nature Communications
Dairy pastoralism reached Mongolia during the Early Bronze Age and flourished in the Late Bronze Age alongside the emergence of diverse mortuary practices, including the Deer Stone-Khirgisuur Complex and figure-shaped/Ulaanzuukh burials. While the spread
