Impact of Ball Milling on the Microstructure of Polyethylene Terephthalate [PDF]
ChemSusChem, Volume 18, Issue 4, February 16, 2025.Milling PET: This study investigated the impact of ball milling at different frequencies on polyethylene terephthalate (PET) samples of different crystallinity and particle size. Percent crystallinity (from both differential scanning calorimetry and powder X‐ray diffraction), particle size, as well as size and shape of the milled PET were measured ...

Re‐assessing regional chronologies for island southeast Asian voyaging to Aboriginal Australia
Archaeology in Oceania, Volume 58, Issue 3, Page 245-274, October 2023., 2023 ABSTRACT According to written histories, trepang fishers from Island Southeast Asia (“Makassans”) frequented coastal northern Australia from c.1750 to 1907 CE. Yolŋu oral traditions and old Austronesian borrow words in coastal Aboriginal languages suggest a long and complex history of foreign voyaging to northern Australia.

The Material Basis of 18th‐Century Meissen Porcelain
Archaeometry, EarlyView.ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Archaeometry, Volume 68, Issue 1, Page 120-131, February 2026.ABSTRACT With this contribution, an attempt is being made to chart the timeline of the invention of the European hard‐paste porcelain based on historical documents. They were evaluated to trace the development lines from Tschirnhaus's early experiments with burning mirrors and lenses in the 1680s to finding ‘wax porcelain’ around 1694 to the ...

American Anthropologist, Volume 127, Issue 4, Page 757-776, December 2025.ABSTRACT This paper examines local taste practices in the era of “legitimate trade” when the trade in botanical (e.g., palm oil, palm kernel oil, and cocoa) and nonbotanical (e.g., ivory, textiles) commodities replaced the trade in enslaved Africans. Following the 1807 British abolition of the Atlantic trade in enslaved people, the locus of the trade ...

Fabrication of Novel Acid‐Resistant Ceramic With High Abrasion and Flexural Strength Resistance
International Journal of Ceramic Engineering &Science, Volume 7, Issue 6, November 2025.ABSTRACT In this research, the innovative ceramic production process begins with the drying and grinding of raw materials to a fine powder, which is then sieved and dampened before being shaped into ceramic forms using a stainless‐steel mold. The material is pressed at 400 bars for 15 s to form a 10‐mm‐thick ceramic.

The Use of Ornamental Stone Waste (OSW) as Raw Material for Porcelain Ceramic Tiles Production
International Journal of Ceramic Engineering &Science, Volume 7, Issue 5, September 2025.ABSTRACT Despite the relevant contribution of the ornamental stone industry to the international economy, the large volume of waste generated during the production process is one of the main problems faced by the sector. Currently, the ceramic industry has shown to be a powerful alternative for the use of these wastes.

Effect of nanosilica and nanoboehmite in the pyroplastic deformation of a porcelain tile paste
International Journal of Applied Ceramic Technology, Volume 22, Issue 5, September/October 2025.Abstract Porcelain tiles are low‐porosity ceramic coatings, formed by a mixture of clay minerals, quartz, and feldspars, and fired at temperatures close to 1200°C with formation of a liquid phase that can result in unwanted pyroplastic deformations. In addition, the rectangular formats, large dimensions, reduced thicknesses, and fast thermal cycles ...
