Distributed opto-mechanical analysis of liquids outside standard fibers coated with polyimide

, 2019
The analysis of surrounding media has been a long-standing challenge of optical fiber sensors. Measurements are difficult due to the confinement of light to the inner core of standard fibers.

Microscale Templating of Functional Particles Using Self‐Limiting Electrospray Deposition

Small, EarlyView.
Self‐limiting electrospray deposition (SLED) uses trapped charge in a growing film to redirect incoming material and produce highly targeted and uniform sprays. Here, nanoparticles are added to sprays to functionalize pre‐patterned electrodes and other devices.

Monitoring Interfacial Dynamics of a Zinc‐Ion Battery Cathode Using In Situ Grazing Incidence X‐Ray Absorption Spectroscopy: A Case Study of Manganese Dioxide

Small Methods, EarlyView.
This study demonstrates the first in situ application of grazing incidence X‐ray absorption spectroscopy (GI‐XAS) to probe interfacial degradation in MnO2 cathodes of zinc‐ion batteries. By varying the incidence angle, surface‐ and bulk‐specific redox changes are revealed, highlighting Mn dissolution and incomplete reoxidation as key factors driving ...

Electrolyte gate dependent high-frequency measurement of graphene field-effect transistor for sensing applications

, 2014
We performed radiofrequency (RF) reflectometry measurements at 2.4 GHz on electrolyte-gated graphene field-effect transistors (GFETs) utilizing a tunable stub-matching circuit for impedance matching.

Experimental investigation on the cracking process of primary and secondary cracks in thick concrete members

Structural Concrete, EarlyView.
Abstract The decisive reinforcement of thick concrete members is often determined by the minimum reinforcement for crack control due to restraint stresses. In contrast to the heuristic design model in Eurocode 2, a mechanically sound methodology is only provided if the deformation compatibility is considered.

Radiation‐Induced Degradation in Polymeric Materials: Alterations in Physical–Chemical Properties and Their Effects on Electrical Performance of Insulation Systems

High Voltage, EarlyView.
ABSTRACT This paper investigates the effects of radiation on polymeric materials used as insulation systems in electrical equipment such as cables for nuclear and particle accelerator applications. After a detailed description of the physics of radiation‐induced damage in the polymeric matrix, a comprehensive analysis of the physical–chemical and ...
