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 ...

Interaction Between Convection and Pulsation [PDF]

open access: yes, 2015
This article reviews our current understanding of modelling convection dynamics in stars. Several semi-analytical time-dependent convection models have been proposed for pulsating one-dimensional stellar structures with different formulations for how the

Convection in the Sun [PDF]

open access: yesInternational Astronomical Union Colloquium, 1990
AbstractThe present knowledge of the dynamics and structure of the solar convection zone is reviewed with the aim of checking current assumptions and conjectures against laboratory experiments and numerical modeling of thermal convection. Buoyancy is the only forcing considered. Rotation and magnetic fields are explicitly avoided.

Designing Metastable P3‐type Layered Negative Electrodes with High Na Vacancy Concentration for High‐Power Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A metastable high‐vacancy concentration layered P3‐type Na0.5Cr0.5Ti0.5O2 negative electrode material has been synthesized from its K analogues P3‐type K0.5Cr0.5Ti0.5O2 using a facile room temperature ion‐exchange method. The P3‐type Na0.5Cr0.5Ti0.5O2 demonstrates a gravimetric capacity of 125 mA h g−1 and high‐rate performance (80% charging in 3 min ...

Geodynamic evolution of a wide plate boundary in the Western Mediterranean, near-field versus far-field interactions

open access: yesBSGF - Earth Sciences Bulletin, 2021
The present-day tectonic setting of the Western Mediterranean region, from the Pyrénées to the Betics and from the Alps to the Atlas, results from a complex 3-D geodynamic evolution involving the interactions between the Africa, Eurasia and Iberia plates

Convection in colloidal suspensions with particle-concentration-dependent viscosity

open access: yes, 2010
The onset of thermal convection in a horizontal layer of a colloidal suspension is investigated in terms of a continuum model for binary-fluid mixtures where the viscosity depends on the local concentration of colloidal particles.

Quantifying Convective Aggregation Using the Tropical Moist Margin's Length

open access: yesJournal of Advances in Modeling Earth Systems, 2020
On small scales, the tropical atmosphere tends to be either moist or very dry. This defines two states that, on large scales, are separated by a sharp margin, well identified by the antimode of the bimodal tropical column water vapor distribution ...

A model of rotating convection in stellar and planetary interiors: I - convective penetration [PDF]

open access: yes, 2019
A monomodal model for stellar and planetary convection is derived for the magnitude of the rms velocity, degree of superadiabaticity, and characteristic length scale as a function of rotation rate as well as with thermal and viscous diffusivities. The convection model is used as a boundary condition for a linearization of the equations of motion in the
