In-Flow Heterogeneous Triplet–Triplet Annihilation Upconversion
ACS Physical Chemistry AuPhoton upconversion based on triplet-triplet annihilation (TTA-UC) is an attractive wavelength conversion with increasing use in organic synthesis in the homogeneous phase; however, this technology has not performed with canonical solid catalysts yet. Herein, a BOPHY dye covalently anchored on silica is successfully used as a sensitizer in a TTA system

Behaviour of twin- and triplet-born lambs and their dam 3 to 18 hours after birth is not a useful predictor of lamb survival to weaning [PDF]
Asian-Australasian Journal of Animal Sciences, 2020 Objective An experiment was designed to determine if behaviour traits expressed by twin- and triplet-bearing lambs and their dams at 3 to 18 hours of age (after the immediate ewe-lamb bonding had occurred) were associated with lamb survival to weaning ...

Triplet‐triplet Annihilation Dynamics of Naphthalene
Chemistry – A European Journal, 2022 AbstractTriplet‐triplet annihilation (TTA) is a spin‐allowed conversion of two triplet states into one singlet excited state, which provides an efficient route to generate a photon of higher frequency than the incident light. Multiple energy transfer steps between absorbing (sensitizer) and emitting (annihilator) molecular species are involved in the ...

Triplet-triplet decoherence in singlet fission [PDF]
Physical Review B, 2020 Singlet fission is commonly defined to involve a process by which an overall singlet state with local triplet structure spin-decoheres into two triplet states, thereby completing the fission process. This process, often defined in loose terms involving the multiplicity of the overall state, is investigated here using a uniform Heisenberg spin-chain ...

ESMO Gastrointestinal Oncology, 2023 The two key concerns in treating locally advanced rectal cancer (LARC) are as follows: (i) prolonging survival by reducing distant metastases and (ii) maintaining anorectal function and quality of life in surviving patients by safely avoiding rectal ...

Case for the genetic code as a triplet of triplets [PDF]
Proceedings of the National Academy of Sciences, 2017 Significance The genetic code for life is a triplet base code. It is known that adjacent codons can influence translation of a given codon and that codon pair biases occur throughout nature. We show that mRNA translation at a given codon can be affected by the two previous codons.
