Capillary Electrophoresis With Amperometric Detection for Neurotransmitter Analysis: Principles, Electrode Materials, Methodologies, and Applications

open access: yesELECTROPHORESIS, EarlyView.
This review provides a comprehensive summary of monoamine neurotransmitter analysis by capillary electrophoresis with amperometric detection. Fundamental principles of amperometric detection, electrode positioning strategies, and approaches to high‐voltage decoupling are described, followed by a critical comparison of electrode materials, selection of ...

Coupled Fluid–Structure–Acoustic Analysis of Flow‐Induced Noise Control Using an Elastic Baffle in a Micro Channel

open access: yesEnergy Science &Engineering, EarlyView.
This research explores how fluid flow, structural movement, and sound interact in an elastic baffle system. Using a numerical approach based on the finite element method, the study analyzes how noise and vibrations change with different baffle configurations. The findings reveal that shortening the baffle by half reduces noise transmission by 9%, while

Vibrational and acoustic response of ribbed plates

open access: yes, 2018
A self-consistent mathematical formulation, using the Fourier transform method and a direct Gaussian numerical integration scheme, is developed and verified for analysis of both vibrational and acoustic responses of infinite submerged ribbed plates.

Hybrid Oxygen Enrichment and Preheating Strategy for Performance Recovery in Ultra‐Lean Micro–Trapped Vortex Combustors

open access: yesEnergy Science &Engineering, EarlyView.
Ultra‐lean H2 micro‐combustor performance is boosted through regulated O2 enrichment and inlet preheating. A 16‐case Taguchi study (ϕ = 0.3) shows: controlled enrichment and heating increase radiative output and efficiency, but excessive O2/temperature causes flashback.
