A Novel Bipolar DC Connection Strategy for Photovoltaic Power Plants With a 50% Reduction in DC Cabling Length

open access: yesEnergy Science &Engineering, EarlyView.
Bipolar configuration is a new topology in the direct current (DC) system of photovoltaic power plants, which is topologically analogous to the bipolar configuration utilised in High‐Voltage Direct Current power transmission systems. DC cable length and copper usage are reduced by 50% using a bipolar configuration.

Pulsed Light Technology in Food Safety and Preservation: Principles, Applications, and Future Directions

open access: yesFood Chemistry International, EarlyView.
Pulsed light technology uses short high‐intensity broad‐spectrum flashes (200–1100 nm) to inactivate microbes via DNA damage. It preserves food quality, extends shelf life, and works on liquids, meats, and produce, often combined with other hurdles for enhanced efficacy.

Non‐fullerene acceptor aggregation regulation via additives dipole moment leads to 19.9% power conversion efficiency in bilayer organic solar cells

open access: yesFlexMat, EarlyView.
Additives interact with non‐fullerene acceptors to modulate their aggregation behavior and molecular orientation via optimizing crystallization kinetics. The optimized morphology effectively suppresses charge carrier recombination and enhances charge transport. Notably, 2‐chloro‐1,3‐dibromobenzene with the dipole moments of 2.56 D enables the PM6/L8‐BO

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

open access: yesInfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Decadal Changes of UV Aerosol Optical Depth in Hobart, Australia Measured With a Brewer MKIII: Relationship to Bushfire Events and Climate Indices

open access: yesInternational Journal of Climatology, EarlyView.
Monthly average aerosol optical depth at 320 nm obtained with a Brewer MKIII spectrophotometer for Hobart, Australia (42.8806° S, 147.3250° E) over a 21‐year period. There is a linear trend of 15.4% per decade. There are 9 months when the average aerosol optical depth exceeds twice the monthly standard deviation.

Method Based on Continuous Artificial Dry and Humid UV Treatments to Reduce the Luminescence Background in the Raman Spectra of Plastics

open access: yesJournal of Raman Spectroscopy, EarlyView.
We propose an UV photobleaching pretreatment to reduce the strong luminescence in the Raman spectra of plastic samples. Our protocol proves its efficiency whatever the luminescence origin (from the pigments or from a surface biofilm) but requires a careful optimization of the illumination conditions (UV wavelength, time, humidity) to reach the ...

Reaction Rate Coefficients and Adduct Formation in the Cl Atom + (E)‐CF3CF2CH=CHCF2CF3 Reaction

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT In this work, rate coefficients for the Cl‐atom + (E)‐CF3CF2CH═CHCF2CF3 (HFO‐153‐10mczz, F22E) gas‐phase reaction were measured as a function of temperature and pressure, k(243–323 K, 50–300 Torr), using a pulsed laser photolysis‐resonance fluorescence (PLP‐RF) technique.

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature‐depth, fluorescence,

Correlating Mid‐Infrared Absorption With Radiative Efficiency in Passive Daytime Radiative Cooling Systems

open access: yesMacromolecular Rapid Communications, EarlyView.
We establish a correlation between the mid‐IR photonic response of Passive Daytime Radiative Cooling systems and their thermal radiation performances, characterized within a dedicated setup that simulates the irradiance toward outer space under controlled and reproducible conditions.
