Photothermal Nanomaterials: A Powerful Light-to-Heat Converter

open access: yesChemical Reviews, 2023
All forms of energy follow the law of conservation of energy, by which they can be neither created nor destroyed. Light-to-heat conversion as a traditional yet constantly evolving means of converting light into thermal energy has been of enduring appeal ...

Controlling Light Harvesting with Light [PDF]

open access: yesJournal of the American Chemical Society, 2016
When exposed to intense sunlight, all organisms performing oxygenic photosynthesis implement various photoprotective strategies to prevent potentially lethal photodamage. The rapidly responding photoprotective mechanisms, occurring in the light-harvesting pigment-protein antennae, take effect within tens of seconds, while the dramatic and potentially ...

Is the Light too Light? [PDF]

open access: yes, 2012
The gravitational interaction of light is analyzed considering its dual characteristic nature, i.e., as an (electromagnetic) wave or as a particle (photon). Considered as an electromagnetic wave, the light can be source of gravitational waves belonging to the larger class of exact solutions of Einstein field equations which are invariant for a non ...

On the creation of a photon by an electromagnetic wave ball

open access: yesScientific Reports, 2023
Recent literature has shown, theoretically as well as experimentally, that while a beam splitter does not split a single photon, it nonetheless divides the electromagnetic wave into transmitted and reflected, with both containing energies.

Contrefaire l’art ou contrefaire la nature : l’analogie artistique pour la restauration écologique

open access: yesCybergeo, 2009
Andrew Light examines the debates on restoration ecology between Robert Elliot and Eric Katz. Rather than taking on their strong metaphysical distinction between nature and culture, as some critics do, he assumes it is true and then argues that it does ...
