Effect of Sequential and Combined Space‐Based Stressors on Perovskite Solar Cell Stability

EcoEnergy, EarlyView.
A correlation between loss in performance and mobile ion concentration has been established by sequential stressing of perovskite solar cells under Low Earth Orbit conditions with exposure to protons, light, and thermal cycling. It is shown that the loss in performance increases when ion concentration increases and vice versa.

Vaginal host–microbe signatures linked to placental outcomes in mares

Equine Veterinary Journal, EarlyView.
Abstract Background Ascending placentitis is a leading cause of late‐term pregnancy loss in mares. Although pathogens are presumed to ascend from the caudal reproductive tract, the association between the vaginal microbiome and placentitis has not been systematically examined.

Mechanosynthesis of Metal‐Free Molecular Perovskites

Helvetica Chimica Acta, EarlyView.
ABSTRACT Metal‐free halide perovskites have recently emerged as promising candidates for optoelectronic applications. However, their synthesis has largely depended on water‐based single‐crystal growth that limits material diversity, scalability, and practical implementation.

Quantification of Modelling Uncertainties in Bridge Scour Risk Assessment under Multiple Flood Events

Geosciences, 2019
Local scour is a dynamic process evolving during the lifetime of bridges as a result of the changes in hydrologic and hydraulic conditions. Current approaches for scour risk assessment are generally based on the evaluation of the equilibrium scour depth ...

SCOUR NEAR SPILL-THROUGH TYPE ABUTMENT ON CLEAR-WATER SCOUR CONDITION FOR MULTI-SECTION CHANNELS

, 2009
Scour is a natural phenomenon caused by erosion due to water flow on the alluvial channel bed and channel wall. In fact, scour happened in the bridge abutment is total scour, that is a combination between local scour, general scour, and constriction ...

Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

Physical and numerical modeling for the investigation of downstream scour caused by sudden blockage in circular and box culvert inlets [PDF]

Journal of Applied Research in Water and Wastewater
This paper presents a comprehensive experimental and numerical study using non-cohesive uniform sand (d50 = 2 mm). The study investigates the impact of local scour downstream of four model culverts with different barrel shapes and inlet blockage sizes ...

Scour of Clear Water Rock W-Weirs in Straight Rivers

, 2014
Scour characteristics downstream of rock W-weir structures were studied in a horizontal straight channel and under clear water conditions. For each structure, different hydraulic conditions were considered, including densimetric Froude numbers, water ...

Dermatologic Best Practices for Manicures and Nail Care: A Systematic Review

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Manicure and pedicure procedures are widely viewed as benign cosmetic practices, yet emerging evidence links them to various dermatologic complications, including dermatitis, infection, photodamage and, in rare cases, cutaneous malignancy.
