In organic molecules, an exciton is a particle bound pair of an electron (negative charge) and its hole (positive charge). They are held together by Coulombic attraction and can move within molecular ...

SF results from the absorption of a single particle of light, or photon, in molecules called chromophores (molecules that ...

Singlet fission (SF) is an exciton amplification phenomenon in which two triplet excitons are generated from a singlet ...

a, The idealized chemical structure of MEH-PPV.b, Schematic showing idealized chromophores along a conjugated polymer backbone.The rectangles represent planar, conjugated chromophore segments of ...

In contrast, the chromophores coupled to opsins don’t pose that problem. They merely change shape when they absorb light, and they can easily change back. So when melatonin-binding proteins ...

In this article, we explore treatment options for fibromyalgia, what current research can tell us about the disease and what ...

Oct. 31, 2024 — Researchers have come up with a way to turn silicon into a direct bandgap semiconductor, opening the door to the manufacture of ultrathin silicon ... Development of a Simple ...

Multichannel, multiphoton excitation imaging is accomplished with a dual-wavelength IR pulsed laser or two independent IR pulsed lasers - enabling simultaneous excitation of chromophores with ...

Oct. 30, 2024 — Research provides a deeper understanding of precisely what is happening in organic solar cells as light is converted into electricity. Researchers developed a new method which ...

Broadening the study away from achiral fibres, an intrinsically chiral aggregate gives a 'true' CD signal because the chiral centres in the component molecules lead to a chiral arrangement of the ...

Colgate explains why more and more patients are opting for whitening and how dentists can help them to achieve their desired results.

A team of Japanese researchers has discovered a new technique to tweak molecular orientation that could dramatically improve energy transfer when absorbing light. While in its infancy, this ...
