Interconnected Porous Hydrogels with Tunable Anisotropy Through Aqueous Emulsion Bioprinting

open access: yesAdvanced Functional Materials, EarlyView.
A 3D bioprintable microporous bioink is developed using an aqueous two‐phase system (ATPS) composed of extracellular matrix (ECM) mimetic biopolymers. The ATPS bioink enables the fabrication of interconnected porous architectures with up to 70% porosity, supporting long‐term cell viability and 3D cell alignment, enabling a simultaneous generation of ...

Poznámky k interpretačnímu potenciálu běžných sídelních areálů doby bronzové [PDF]

open access: yesStudia Hercynia, 2015
Since the second half of the 20th century, large‑scale rescue excavations have unearthed numerous common Bronze Age lowland settlement areas. The development of archaeological theory and method and principally of accessible software tools enables their

Kitchenalia in Bronze Age Cyprus [PDF]

open access: yes, 2016
This article explores the materiality of food production and consumption within the household in Bronze Age Cyprus. The focus is on embodied encounters with the “stuff of food”—the pots, pans, and other kitchen implements that were used on a daily basis ...

Robust and Reversible Thermofluorescence in Solvent‐Free Thermoplastic Polyurethane Composites

open access: yesAdvanced Functional Materials, EarlyView.
Thermofluorescent polymer composites with high‐contrast optical outputs are prepared by solvent‐free blending of indenoquinacridone dye into a thermoplastic polyurethane matrix. The temperature‐dependent fluorescence originates from aggregation–dissociation of the dye molecules, regulated by competing hydrogen bonds from the polymer matrix.

From Wax to Metal: An Experimental Approach to the Chaîne Opératoire of the Bronze Disk from Urdiñeira

open access: yesEXARC Journal, 2013
The so-called ‘Treasure of A Urdiñeira‘ (A Gudiña, south-east of the province of Ourense, Spain) consists of an assemblage of three metal artefacts: two gold bracelets and a bronze button or disk, dated from the transition between the Late Bronze Age and

A Biologically‐Architected Wear and Damage‐Resistant Nanoparticle Coating From the Radular Teeth of Cryptochiton stelleri

open access: yesAdvanced Functional Materials, EarlyView.
The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

A Mesolithic settlement site at Howick, Northumberland: a preliminary report [PDF]

open access: yes, 2003
Excavations at a coastal site at Howick during 2000 and 2002 have revealed evidence for a substantial Mesolithic settlement and a Bronze Age cist cemetery. Twenty one radiocarbon determinations of the earlier eighth millennium BP (Cal.) indicate that the

All‐Aqueous Pullulan Fibers Enabling Visible‐to‐Near‐Infrared Waveguiding with Mechanical and Thermal Resilience

open access: yesAdvanced Functional Materials, EarlyView.
Pullulan, a biomass‐derived polysaccharide, is transformed into transparent optical fibers using a solvent‐free borax hydrogel‐spinning method. The fibers outperform PMMA with ≈200 MPa tensile strength and 200 °C stability, while uniquely guiding visible‐to‐NIR light and enabling additive‐free humidity sensing.
