Composition pinning growth for efficient and stable all‐inorganic Pb‐Sn perovskite solar cells

InfoMat, EarlyView.
All‐inorganic Pb‐Sn perovskite solar cells are promising for low‐bandgap photovoltaics, but uneven Pb/Sn composition during film growth can create defects and reduce performance. In this study, composition pinning growth was used to hold the Pb/Sn ratio steady during CsPb0.5Sn0.5I3 crystallization, producing more uniform films and higher‐performing ...

Interacción punta-muestra dieléctrica en microscopía de fuerza electrostática

Revista Facultad de Ingeniería Universidad de Antioquia, 2009
La microscopía de fuerza electrostática es una técnica de medición de propiedades eléctricas locales de materiales. Las mediciones de gradiente de fuerza eléctrica sobre muestras dieléctricas son sensibles no sólo a la distribución de carga inicial en la

Scalable Manufacturing of Amino Acid‐Based Piezoelectric Biocrystal Films

Small, EarlyView.
This work presents a continuous manufacturing strategy for glycine‐PVA piezoelectric films through dynamically controlled crystallization. This stable and industrially viable strategy offers significant potential for mass production of piezoelectric biocrystal films and biocompatible devices.

The effect of continuous electronic fetal monitoring on mode of delivery and neonatal outcome among low-risk laboring mothers at Debre Markos comprehensive specialized hospital, Northwest Ethiopia

Frontiers in Global Women's Health
BackgroundElectronic fetal heart rate monitoring (EFM) has been widely used in obstetric practice for over 40 years to improve perinatal outcomes. Its popularity is growing in Ethiopia and other sub-Saharan African countries to reduce high perinatal ...

Bayes Theorem and Protopathic Bias: Methodological Concerns When Addressing the Impact of Fetal Heart Rate Patterns on the Cesarean Section Rate

American Journal of Perinatology Reports, 2020
Over the last 30 years, the caesarean section rate has reached global epidemic proportions. This trend is driven by multiple factors, an important one of which is the use and inconsistent interpretation of the electronic fetal monitoring (EFM) system ...

Quantitative Analysis of Topographic Crosstalk in DART‐ESM Arising from Feedback‐Loop‐Delay‐Induced Contact Stiffness Variations in Battery Materials

Small Methods, EarlyView.
Interpretation of Dual AC Resonance‐Tracking Electrochemical Strain Microscopy (DART‐ESM) signals is complicated by topography‐induced artifacts that distort measured responses. Using silicon with artificial trench structures as a reference, this study quantifies artifact magnitude and demonstrates that Cooling Cross‐Section Polishing (CCP) effectively

Electrostatic force microscopy for the accurate characterization of interphases in nanocomposites

Beilstein Journal of Nanotechnology, 2018
The unusual properties of nanocomposites are commonly explained by the structure of their interphase. Therefore, these nanoscale interphase regions need to be precisely characterized; however, the existing high resolution experimental methods have not ...

The Impact of Working from Home on Obesity in Australia*

Economic Papers: A journal of applied economics and policy, EarlyView.
Obesity is one of the most prevalent health challenges in high‐income countries, prompting growing policy interest in identifying its underlying determinants to inform effective interventions. This study contributes to the literature and policy debate by using long‐run Australian panel data and an instrumental variable approach to estimate the causal ...
