Flux Analysis of the Supercapacitor Performance at Component Level

open access: yesAdvanced Materials Technologies, EarlyView.
The central objective of this study is to introduce new approach and metrics for analyzing the supercapacitor performance at the component level. The lack of standardized evaluation methodologies for analyzing the nonlinear behavior of real system is critical and hinders progress of supercapacitor.

The shear behavior of CFRP Strengthened RC beams

open access: yesMagazine of Civil Engineering, 2020
The primary objective of this paper is to study the effectiveness of using externally applied CFRP composites as a method of shear strengthening. The parameters investigated in this study included CFRP amount and distribution (i.e., sheet versus strips), bonded surface (i.e., web sheet versus U-wrap), and fiber orientation (i.e., 90° fiber direction ...

Electroluminescence and Franz–Keldysh Modulation Observed in Sn/Ge Multi‐Quantum Wells

open access: yesAdvanced Optical Materials, EarlyView.
We investigate the optoelectronic properties of PIN diodes based on ultrathin α‐Sn/Ge multiple quantum film structures, fabricated by molecular beam epitaxy, both experimentally and theoretically. The samples exhibit a light emission spectrum in the short‐wavelength infrared range with two transitions. Furthermore, when operating as a photodetector, we

Flexural performance of reinforced concrete beams repaired using conventional cementitious mortars

open access: yesJournal of Infrastructure Preservation and Resilience
Initial defects in reinforced concrete (RC) structures frequently arise during and after construction due to deficiencies in materials, methods, workmanship, or environmental conditions.

Terahertz Waveform‐Selective Antenna Using a Patch Structure Loaded with Nonlinear Circuits

open access: yesAdvanced Photonics Research, EarlyView.
A waveform‐selective antenna that integrates the functions of waveform selectivity, electromagnetic shielding, and EM wave radiation has been proposed. By integrating different nonlinear circuits and selecting appropriate component values, the antenna can achieve high reflection of either a pulse wave or a continuous wave, while allowing the other ...
