Precision Stress Engineering in Tensegrity‐Inspired Nanoarchitectures Enabled by Size‐Affected Shrinkage

Small, EarlyView.
This work identifies a size‐dependent shrinkage effect that arises during polymer pyrolysis and uses it to embed residual stress into tensegrity‐inspired nanoarchitectures. By adjusting the dimensions of the structural elements, controlled prestress can be introduced in a simple and repeatable manner, enabling mechanically tunable nanostructures with ...

High-fidelity database of supercritical homogeneous isotropic turbulence in the pseudo-boiling region

Scientific Data
Supercritical fluids operate above their critical point and are characterized by strong nonlinearities in the equation of state, highly non-ideal fluid behavior, and a tight coupling between thermodynamics and transport properties.

Hunting method affects cortisol levels in harvested mountain hares (Lepus timidus)

Wildlife Biology, EarlyView.
The direct effects of hunting on hunted individuals and populations have been well known for a long time. However, recently there has also been an increased focus on the indirect, non‐lethal effects of hunting. When approached by a possible threat such as a predator, the prey releases various stress hormones into the bloodstream.

Simultaneous Formation of Arsenic Nitride Chalcogenides As3NS3 and As3NSe3 and Arsenic–Chalcogen Zintl Anions by Ammonothermal Reactions

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Mn, As, and S or Se react in liquid NH3 to the Zintl ions (As4S6)2– and (As2Se6)2–. Simultaneously, the arsenic nitride chalcogenides As3NS3 and As3NSe3 are formed. Their isotypic structures contain planar trigonal NAs3 groups connected via chalcogen bridges to 1D‐strands forming channels that can host solvent molecules.

Stratigraphic evidence for modern‐like glacier extents in south‐central Alaska within the last glacial period (MIS 3)

Boreas, EarlyView.
The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct local climatic events and compare them to global trends.

From plant to fabric: Environmental opportunities associated with annatto dye for sustainable development in the textile industry

Coloration Technology, EarlyView.
Abstract Natural dyes are compounds that occur naturally in several organisms and are classified based on chemical structure and application method. The literature cites several natural dyes used in industrial transformation processes. Annatto dye is used in the food industry, and its biological pigment is extracted from the annatto seed. However, this
