Archaeology in Oceania, Volume 58, Issue 3, Page 227-244, October 2023., 2023 ABSTRACT Technological analysis of the late Holocene component of the stone artefact assemblage recovered from the Kings Table rockshelter in the Blue Mountains, west of Sydney, provides the basis for an assessment of the site's role in broader late Holocene settlement‐subsistence systems. Drawing on Kuhn's widely employed “provisioning model”, as well

Amination of Polymeric Braid Structures to Improve Tendon Healing: An Experimental Comparison
Macromolecular Materials and Engineering, Volume 308, Issue 1, January 2023., 2023 Poly(ethylene terephthalate) (PET) and poly(lactic acid) (PLA) are polymers useful in tendon repair, though with minimal success. There is a need to improve such scaffolds' design and physical–chemical nature. The work concerns functionalization of PET/PLA braids to incorporate amine groups in the braids' surface, improve cell adhesion, and ...

Treatment of Silylene-Phosphinidene with Chalcogens Resulted Exclusively in the Formation of Silicon-Bonded Chalcogens. [PDF]
Chemistry, 2019 Join the main‐group meeting: Chalcogen‐bonded silicon(IV) phosphinidenes LSi(E)−P−MecAAC (E=S, Se, Te) were synthesized from the reactions of silylene–phosphinidene LSi−P−MecAAC with elemental chalcogens. These are the first molecular examples in which a Si=E group is attached to a phosphinidene moiety.
