Closing the Loop in Agrivoltaics: A Radiative Cooling Coating for Synergistic Self‐Cleaning and Water Harvesting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A nanostructured photonic‐thermal coating enables radiative‐cooling‐induced condensation and water harvesting, establishing a self‐sustaining agrivoltaics microclimate loop that transforms PV panels into active climate regulators. The integration of photovoltaic (PV) panels into agricultural landscapes (i.e., agrivoltaics) offers a promising path for ...

Effect of AEA-SP Dosage Sequence on Air Entrainment in FA Concrete

open access: yesNordic Concrete Research, 2019
Laboratory measurements show that varying the dosage sequence of air-entraining agent and co-polymer in the mix (SP added before, after or together with AEA) greatly affects air entrainment in fresh and hardened fly ash concrete.

INVESTIGATION ON EFFECTS OF ENLARGED PIPE RUPTURE SIZE AND AIR PENETRATION TIMING IN REAL-SCALE EXPERIMENT OF SIPHON BREAKER

open access: yesNuclear Engineering and Technology, 2014
To ensure the safety of research reactors, the water level must be maintained above the required height. When a pipe ruptures, the siphon phenomenon causes continuous loss of coolant until the hydraulic head is removed.

Towards retrieving cloud top entrainment velocities from MISR cloud motion vectors [PDF]

open access: yesAtmospheric Measurement Techniques
Although important, direct retrievals of entrainment rates in cloud-topped planetary boundary layer (PBL) remain elusive. Here we present a novel technique for retrieving cloud-top entrainment velocities using only Multi-angle Imaging Spectro-Radiometer (

Pneumothorax Ex Vacuo. [PDF]

open access: yesJ Gen Fam Med
An 84‐year‐old woman with pleural effusion developed anterior chest pain during thoracentesis, and post‐procedural chest radiography revealed hydropneumothorax, initially suggesting iatrogenic pneumothorax. However, comparison of pre‐ and post‐procedure imaging showed ipsilateral hemithoracic volume loss with tracheal deviation toward the procedure ...

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation

open access: yesFire and Materials, EarlyView.
ABSTRACT Wind can significantly influence fire development and spread in urban and forest environments causing fatal consequences for the public, the first responders, and the environment. Wind‐driven fires can have a significant impact on structural fires as wind can increase the fire's intensity, development, and flame spread.
