Remote Sensing of Snow Cover Using Spaceborne SAR: A Review

open access: yesRemote Sensing, 2019
The importance of snow cover extent (SCE) has been proven to strongly link with various natural phenomenon and human activities; consequently, monitoring snow cover is one the most critical topics in studying and understanding the cryosphere.

Cloud Inspired White and Grey Plasmonic Metasurfaces for Camouflaged Thermal Management

open access: yesAdvanced Materials, EarlyView.
Inspired by clouds' role in Earth's thermal management, this work presents disordered plasmonic metasurfaces that mimic their radiative effects. The white metasurface enhances backscattering, acting as a cooling layer with camouflage properties.

Understanding factors influencing care seeking for sick children in Ebonyi and Kogi States, Nigeria

open access: yesBMC Public Health, 2020
Background Nigeria has one of the highest child mortality rates in the world, with an estimated 750,000 deaths annually among children under age five. The majority of these deaths are due to pneumonia, malaria, or diarrhea.

Triboelectric Nanogenerators Enable Multifunctional Ice Accretion, Melting, and Interfacial Fracture Detection

open access: yesAdvanced Materials, EarlyView.
Water impacting, freezing, melting, and being mechanically removed from the designed dielectric surfaces generates a triboeletric signal that can be used to detect various icing and de‐icing scenarios. The charge transferred directly scales with the interfacial fracture mechanism, further validating triboelectricity as an excellent ice‐detection ...

Wind tunnel experiments: cold-air pooling and atmospheric decoupling above a melting snow patch [PDF]

open access: yesThe Cryosphere, 2016
The longevity of perennial snowfields is not fully understood, but it is known that strong atmospheric stability and thus boundary-layer decoupling limit the amount of (sensible and latent) heat that can be transmitted from the atmosphere to the snow ...
