“…The reported diffraction peaks are aligned with the standard data for metal oxides. As shown in Figure 10a, the diffraction peaks for TiO 2 particles are in good agreement with the JCPDS file of TiO 2 (JCPDS-211 272), [24] whereas XRD peaks for Al 2 O 3 shown in Figure 10b are also compatible with the JCPDS reference file (JCPDS 10-173). [25] Similarly, SiO 2 particles have also shown well-aligned peaks with their reference peaks from JCPDS 05-0492 reference file.…”

Passive radiative cooling has garnered significant attention in energy‐saving applications as it is an effective way to cool to temperatures below ambient without external energy input. Successful cooling performances can be achieved by carefully selecting metal oxides with narrow absorption bands that lie entirely within the atmospheric window of 8−13 μm, thereby allowing radiative transfer between terrestrial objects and outer space. Highly scalable, metal oxide‐doped fibers made from recyclable polystyrene herein are proposed and demonstrated. The material exhibits nearly 100% reflectivity in the visible and near‐infrared (IR) range, and under direct solar irradiation, the material can cool by up to 22.3 °C below the ambient temperature without energy input due to strong emissivity in the atmospheric window. This cooling persists despite nonideal atmospheric conditions and convective/conductive heat exchange. Microsized fiber‐based radiative cooling is reported for the first time. Unlike film‐based passive radiative cooling materials, fibers are relatively simple to manufacture, flexible, lightweight, and low in cost. Therefore, such a material may be suitable for large‐scale applications such as buildings to supplement air conditioning or as a wearable fabric to promote subambient cooling for the wearer.

Fluorescence Investigations on Interactions between 7,8-benzo-4-azidomethyl Coumarin and Ortho- and Para-phenylenediamines in Binary Solvent Mixtures of THF and Water

et al. 2017

Fluorescence investigations on interactions between 7,8-benzo-4-azidomethyl coumarin (7BAMC) and quenchers ortho-phenylenediamine (OPD) and para-phenylenediamines (PPD) in binary solvent mixtures (THF + water) have been reported. UV-absorption study indicated a weak hydrophobic interaction between 7BAMC and the para isomer. NMR spectral studies indicated the presence of an interaction between 7BAMC and PPD. Magnitudes of the parameters associated with FRET, showed the presence of interactions between 7BAMC and PPD quencher is more predominant than OPD. Fluorescence quenching studies reveal the role of static and dynamic quenching pathways, depending upon Stern-Volmer constant, dielectric constant and dominant non-radiative processes. Binding equilibria analysis indicates a strong interaction between 7BAMC and PPD than OPD and formation of H-bonding. Based on the magnitudes of free energy, enthalpy change and entropy, bimolecular interaction process may be considered as spontaneous and hydrophobic.
