Reproducing cloud microphysical and irradiance measurements using three 3D cloud generators

open access: yes, 2007
Using three cloud generators, three-dimensional (3D) cloud fields are reproduced from microphysical cloud data measured in situ by aircraft. The generated cloud fields are used as input to a 3D radiative transfer model to calculate the corresponding ...

Shaping Carbon Nitrides for Advanced Macrostructures

open access: yesAdvanced Materials Technologies, EarlyView.
This review examines how carbon nitride can be shaped through a range of printing and interfacial assembly methods. By bringing together additive manufacturing and liquid–liquid structuring concepts, carbon nitride is moving beyond its traditional powder‐based photocatalyst form toward digitally designed robust macroscale architectures with high design

Revealing the Transmission Hologram's Refractive Index Profile Stored in a Photohydrogel: A Structural Characterization

open access: yesAdvanced Optical Materials, EarlyView.
A theoretical model is developed to visualize three‐dimensional refractive index profiles in transmission holographic gratings. In this work, it is applied to photopolymerizable hydrogels, enabling detailed analysis of the internal structure of recorded holograms and their evolution under different degradation conditions.

Utilizing Downwelling Irradiance for Phytoplankton Determination

open access: yes, 2012
The downwelling irradiance is rarely utilized to determine optical parameters of a water body since the ever-changing water surface induces strong signal fluctuations in the upper meters of typically 20 to 40 %.

Evaluation of a sky/cloud formula for estimating UV‐B irradiance under cloudy skies [PDF]

open access: yes, 2000
A new sky/cloud formula is evaluated using results collected over 1 year from an integrated sky camera and irradiance measurement system. Sky properties were recorded every 6 min, simultaneously alongside solar radiation measurements at Toowoomba ...

Incident spectral solar irradiance measured above sea ice at ROV station ALERT2018_10_1

open access: yes, 2021
Measurements of solar radiation over sea ice have been performed on First-Year-Ice (FYI) during the ALERT2018 campaign (Multidisciplinary Arctic Program (MAP) - Last Ice) off Alert, Nunavut, Canada in the Lincoln Sea on 10 May 2018.

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators

open access: yesAdvanced Robotics Research, EarlyView.
We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.

Effects of irradiance during growth on tolerance of geranium to sub- and supra-optimal boron supply

open access: yes, 2014
In our previous study on geranium, we showed that increases in growth irradiance from sub-optimal to near-optimal could delay boron deficiency effects on photosynthesis. In this study, we further investigated the effects of growth irradiance on tolerance

Cyclodextrin‐Functionalized Light‐Driven Cu2O Micromotors for Simultaneous Capture and Degradation of Bisphenol A

open access: yesAdvanced Robotics Research, EarlyView.
Fuel‐free Cu2O‐based micromotors functionalized with β‐cyclodextrin actively remove bisphenol A from water under visible light. The cyclodextrin shell captures BPA and enhances micromotor motility, leading to faster degradation and higher overall removal than nonfunctionalized Cu2O and Cu2O@Au.

Investigation the effect of the temperature and irradiance on the output parameters of solar cell

open access: yesمجلة علوم ذي قار, 2019
It is important to investigate the effect of the irradiance and temperature on the output performance of the solar cell. Hence, it is possible to estimate the I-V and P-V curves of solar panel under different environmental conditions.
