High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Parents' management of their child's hydrocephalus and shunt [PDF]

open access: yes, 2010
Introduction Shunts are the main treatment for hydrocephalus. When shunts malfunction the consequences are serious and can be life threatening. Identifying shunt malfunction requires effective parent-professional collaboration: parents need to recognise

Shunt Piezoelectric Systems for Noise and Vibration Control: A Review

open access: yesFrontiers in Built Environment, 2019
In this paper, the current state of the art on shunt piezoelectric systems for noise and vibration control is reviewed. The core idea behind the operation of electronic shunt piezoelectric circuits is based on their capability of transforming the dynamic

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

open access: yesAdvanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Torsional wave suppression in metashaft with shunted piezoelectric rings

open access: yesAIP Advances, 2022
This study investigates the bandgap tunability of a metashaft with periodic shunted piezoelectric rings. An analytical model based on the Bloch theory and the transfer matrix technique is developed to predict bandgap characteristics and the transmission ...

Self‐Assembled Monolayers in p–i–n Perovskite Solar Cells: Molecular Design, Interfacial Engineering, and Machine Learning–Accelerated Material Discovery

open access: yesAdvanced Materials, EarlyView.
This review highlights the role of self‐assembled monolayers (SAMs) in perovskite solar cells, covering molecular engineering, multifunctional interface regulation, machine learning (ML) accelerated discovery, advanced device architectures, and pathways toward scalable fabrication and commercialization for high‐efficiency and stable single‐junction and

Hemodynamics in Shunt-PH and No Shunt-PH Patients.

open access: yes, 2015
Values are expressed as mean ± SD.*p < 0.05, shunt group versus no-shunt group using unpaired t test.NT-proBNP = n-terminal natriuretic peptide type-B; mPAP = mean pulmonary artery pressure; mRAP = mean right atrial pressure; PVR = pulmonary vascular ...

Shunt bootstrapping technique to improve bandwidth of transimpedance amplifiers. [PDF]

open access: yes, 1999
The input capacitance of transimpedance amplifiers can limit their response time. One novel technique based on a shunt bootstrap method is shown to be of advantage to op-amp based circuits with a high transimpedance ...

Management of maternal ventriculo-atrial shunt malfunction during pregnancy

open access: yesInterdisciplinary Neurosurgery, 2016
Hydrocephalic females reaching childbearing age is increasing due to treatment advances. It has been suggested that ventriculo-atrial (VA) shunts be preferred over ventriculo-peritoneal (VP) shunts during pregnancy.

Investigation of shunt resistor's connection for a DC Resistive SFCL

open access: yesJournal of Physics: Conference Series, 2010
A DC-operating resistive-type superconducting fault current limiter for AC applications (in short a DC Resistive SFCL) is based on the synergistic use of the resistive and the rectifier fault current limiter concepts, and allows the superconductor to operate in nearly DC current conditions.
