Archaeometry, EarlyView.ABSTRACT In 1837, the Tyrolean State Museum Ferdinandeum in Innsbruck, Austria, purchased a Roman bronze statue of a maenad from the 2nd century ce with red garnets as facetted eye inlays found near Brixen, Southern Tyrol. These garnets were investigated using optical microscopy, a portable hand‐held and a stationary micro‐X‐ray fluorescence device, as

The Journal of Physiology, EarlyView.Abstract figure legend We recorded time‐resolved small‐angle X‐ray diffraction patterns from rat soleus muscles during fixed‐end twitch and tetanic contractions to investigate the structural basis of the lower fixed‐end force generated by these muscles compared with fast muscles, such as the mouse extensor digitorum longus (EDL).

New multiplexing scheme for monitoring fiber optic Bragg grating sensors in the coherence domain
, 1997 A new multiplexing scheme for monitoring fiber optic Bragg gratings in the coherence domain has been developed. Grating pairs with different grating distances are distributed along a fiber line, and interference between their reflections is monitored ...

Sol–Gel Derived Polymer Precursors for Stereolithography of ZrC
Advanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.ZrC is a critical material target for extreme temperature conditions. This report describes a protocol for preparing ZrC ceramics via stereolithography and examines the impact of the polymer matrix on carbothermal reduction and mechanical stability of 3D printed ZrC.

All-optical 160 Gbit/s RZ data retiming system incorporating a pulse shaping fibre Bragg grating
, 2007 We characterize a 160Gbit/s retimer based on flat-topped pulses shaped using a superstructured fibre Bragg grating. The benefits of using shaped rather than conventional pulse forms in terms of timing jitter reduction are confirmed by bit-error-rate ...

Advanced Functional Materials, Volume 36, Issue 37, 7 May 2026.ABSTRACT Breathable membranes that reject chemical warfare agents (CWAs) are required for next‐generation protective apparel. A dual‐function graphene oxide (GO)‐polyamine architecture is introduced that addresses the long‐standing tradeoff between vapor transmission and CWA selectivity.
