Xenon excimer emission from multicapillary discharges in direct current mode [PDF]

open access: yes, 2011
Microdischarges in xenon have been generated in a pressure range of 400–1013 mbar with a fixed flow rate of 100 sccm. These microdischarges are obtained from three metallic capillary tubes in series for excimer emission. Total discharge voltage is thrice

Pulsed Electrolysis Prevents Sulfur Poisoning for Sustained Sulfide Valorization

open access: yesAdvanced Materials, EarlyView.
Integrating pulsed electrolysis with Sc‐doped NiFe‐LDH enables sustainable sulfide valorization, achieving >500 h stability, 99.8% efficiency. Moreover, this technology produces high‐purity sulfur and sodium formate, boosting profit by 121% to $1,294.7 per tonne of hydrogen.

Interpretation of Solar Irradiance Monitor measurements through analysis of 3D MHD simulations

open access: yes, 2014
Measurements from the Solar Irradiance Monitor (SIM) onboard the SORCE mission indicate that solar spectral irradiance at Visible and IR wavelengths varies in counter phase with the solar activity cycle.

An Estimate of Changes in the Sun's Total Irradiance Caused by UV Irradiance Variations from 1874 to 1988 [PDF]

open access: yes, 1990
Enhanced emission from bright solar faculae is a source of significant variation in the sun's total irradiance. Relative to the emission from the quiet sun, facular emission is known to be considerably greater at UV wavelengths than at visible ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Morphology‐Controlled Silica Nanoparticle Coatings for Transparent Radiative Cooling

open access: yesAdvanced Materials Interfaces, EarlyView.
Transparent radiative cooling coatings are achieved by immobilizing solid and hollow silica spheres on glass. Particle morphology within sub‐monolayer coatings is shown to govern the trade‐off between visible and atmospheric window reflectance. Hollow‐sphere structures enable reduced thermal emission losses while preserving transparency, highlighting ...
