A High Sensitive Micro-Seismic Fiber Bragg Grating(FBG) Sensor System
Procedia Engineering, 2011 AbstractA high sensitive micro-seismic fiber Bragg grating (FBG) sensor system based on narrow line width distributed feedback (DFB) laser is realized by using filtering demodulation. Sensitivity of micro-seismic FBG sensor lies on the structure of the sensor shell and the shape of the reflectivity spectrum of FBG.

Addressing Bottlenecks to Achieve High‐Energy Sodium‐Ion Cells Using Tin Anodes
Advanced Energy Materials, Volume 16, Issue 17, 6 May 2026.The challenges in coupling high voltage cathode with Sn‐alloying anode or in anode‐free cell, using glyme based electrolytes to realize high energy Na‐ion cells are reported. Surface protection strategy such as SnO coating on Sn or trapping the parasitic species from poisoning the anode, helps improving the cyclability, with ∼100% capacity retention ...

Anchorage System Contribution to Post‐Tensioned Bridge Collapse
Engineering Reports, Volume 8, Issue 5, May 2026.This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of
