Electronic Control System for Optimized Resonance Operation of Dielectric Elastomer Pumps through Self‐Sensing

open access: yesAdvanced Engineering Materials, EarlyView.
A powerful electronic control system enables a dielectric elastomer pump to operate at resonance, matching conventional pump performance. Using self‐sensing to reconstruct load pressure dynamically, the adaptive control adjusts resonance frequency accordingly.

Characterization of Fe implanted yttria-stabilized zirconia by cyclic voltammetry [PDF]

open access: yes, 1992
The technique of cyclic voltammetry has been applied to study reduction and oxidation phenomena which are observed at low oxygen partial pressures during steady state current-overpotential measurements of the Au, O2(g)/Fe implanted yttria-stabilized ...

Soft Beats: A Dielectric Elastomer‐Based Ventricular Assist Device for Next‐Gen Heart Failure Management

open access: yesAdvanced Engineering Materials, EarlyView.
The dielectric elastomer‐based electropneumatic device (DE‐EPD) is a vacuum‐assisted ventricular assist device (VAD) that delivers high performance (85 mmHg, 6.8 L min−1) with low power consumption. Unlike traditional motor‐driven VADs, it is lightweight, quiet, energy‐efficient, and provides pulsatile flow. Validated in a simulated circulation system,

Comparison of auditory brainstem response peak measures using ear lobe, mastoid, and custom ear canal reference electrodes

open access: yesAudiology Research, 2012
Auditory brainstem response (ABR) peak measures were compared for a custom ear canal electrode and traditional mastoid and ear lobe reference electrode sites with the assumption that the ear canal electrode would yield larger Wave I amplitudes.

Microcellular Poly (Ethylene‐Co‐Vinyl Acetate)/Lignin Nanocomposites for Soft Ferroelectrets

open access: yesAdvanced Engineering Materials, EarlyView.
Lignin valorization for advanced porous polymer nanocomposites development and an upscaling route for continuous manufacturing of soft ferroelectrets for energy harvesting are studied. This work examines the role of lignin and carbon nanotubes (CNT) in modifying the mechanical, dielectric, and ferroelectret properties of poly (ethylene‐co‐vinyl acetate)

Highly Stable Low‐Temperature Phosphate Glass as a Platform for Multimaterial 3D Printing of Integrated Functional Microfluidic Devices

open access: yesAdvanced Engineering Materials, EarlyView.
A highly stable, low‐temperature phosphate glass is developed for multimaterial additive manufacturing of multifunctional microfluidics. Glass, metal conductors, and sacrificial polymer are coprinted, enabling monolithic fabrication. The sacrificial paste forms precise channels and decomposes during sintering.

Efficient and Scalable Radiative Cooling for Photovoltaics Using Solution‐Processable and Solar‐Transparent Mesoporous Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...
