The Typology of the Sapalli Culture Necklaces

Поволжская археология
The Sapalli culture is a culture that was formed in the Northern Bactria region in the Late Bronze Age (2200–1300 BC), and different jewelry (pins, diadems, earrings, beads, necklaces, pendants, amulets, bracelets and rings) have been found at the ...

Synthesis and Interfacial Behavior of Mixed Potassium N‐Lauroyl/N‐Myristoyl Glycinate Surfactants With Varying Alkyl Chain Ratios

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Biodegradable and low‐irritant amino acid–based surfactants have attracted considerable attention as environmentally friendly alternatives to conventional petroleum‐derived surfactants. In this study, a series of acyl amino acid surfactants with identical amino acid head groups but different alkyl chain lengths were synthesized via a modified ...

Preparation of MOEAMCl and MAAm Based Hydrogels and Effective Use in Anionic Dye Adsorption

Journal of Applied Polymer Science, Volume 142, Issue 16, April 20, 2025.
ABSTRACT In this study, hydrogels based on [2‐(Methacryloyloxy)ethyl]trimethylammonium chloride (MOEAMCl) and methacrylamide (MAAm) were synthesized for the removal of anionic dyes from aqueous solutions. Following detailed characterization, the use of hydrogels for methyl orange (MO) adsorption was investigated.

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

Journal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Sleep‐trackers in the wild: A faceted taxonomy for information and interaction design

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Consumer‐grade sleep‐tracking technologies (CSTs) have brought sleep into everyday data practices, reframing it from a clinical concern into a site of personal optimization and reflection. Yet existing taxonomies of sleep‐tracking often medicalize users and overlook the complexity of sleep‐tracking technologies. This paper presents SleepTax, a

Early Chinese Faience and Glass Beads and Pendants

, 2013
The earliest Chinese beads and pendants were composed of faience and appeared during the early Western Zhou period, around the 11th Century B.C. True glass began to be made about the time of the Spring and Autumn period (771-467 B.C.). An amazing variety
