Advanced Engineering Materials, EarlyView.In this study, exciting new bi‐/multi‐linear elastic behavior of soft elastic composites that accompany the activation of wrinkling in the embedded interfacial layers is analyzed. The new features and performance of these composite materials, including dramatic enhancements in energy storage, can be tailored by the concentration of interfacial layers ...

Fiber optical amplifiers [PDF]
Optical Fiber Communication, 1990 It is now accepted by many that for transmission systems operating at 1.55 μm, erbium doped optical fiber amplifiers are superior to semiconductor diode amplifiers. They have higher fiber-to-fiber gain, lower crosstalk and noise, are polarization-independent and do not suffer from facet reflections.

Advanced Engineering Materials, EarlyView.Periodic submicron features are fabricated on 304 stainless steel using single and double femtosecond laser pulses. By adjusting polarization, fluence, and inter‐pulse delay, 1D and 2D nanostructures are formed. Enhanced hydrophobicity and dense surface‐enhanced Raman spectroscopy hotspots enable analyte detection down to 10−10 M with good ...
