Physical review letters

Minitti MP, Budarz JM, Kirrander A, Robinson JS, Ratner D, Lane TJ, Zhu D, Glownia JM, Kozina M, Lemke HT, Sikorski M, Feng Y, Nelson S, Saita K, Stankus B, Northey T, Hastings JB, Weber PM.

Phys Rev Lett. 2015 Jun 26;114(25):255501. doi: 10.1103/PhysRevLett.114.255501. Epub 2015 Jun 22.

Structural rearrangements within single molecules occur on ultrafast time scales. Many aspects of molecular dynamics, such as the energy flow through excited states, have been studied using spectroscopic techniques, yet the goal to watch molecules evolve their geometrical structure...

Culture of one- and two-cell bovine embryos to the blastocyst stage in the ovine oviduct.

Theriogenology

Eyestone WH, Leibfried-Rutledge ML, Northey DL, Gilligan BG, First NL.
PMID: 16726286
Theriogenology. 1987 Jul;28(1):1-7. doi: 10.1016/0093-691x(87)90179-8.

The ovine oviduct was evaluated as a culture system for early bovine embryos. One- to two-cell embryos were collected from superovulated heifers killed 36 or 48 h after the onset of estrus, embedded in agar cylinders, and transferred to...

Spontaneous embryonic death on Days 20 to 40 in heifers.

PMID: 16726905
Theriogenology. 1991 Feb;35(2):351-63. doi: 10.1016/0093-691x(91)90285-l.

Transrectal ultrasound examinations were used in nulliparous Holstein heifers to study the association between time of spontaneous embryonic death (cessation of heartbeat) and luteal regression, and to determine the fate of the conceptus after embryonic death. There was no...

The normal gastrointestinal stroma consists of extra-cellular matrix and a community of stromal cells including fibroblasts, myofibroblasts, smooth muscle cells, pericytes, endothelium and inflammatory cells. α-smooth muscle actin (α-SMA) positive stromal fibroblasts, often referred to as myofibroblasts or activated...

Ultrafast nonadiabatic dynamics probed by nitrogen K-edge absorption spectroscopy.

Physical chemistry chemical physics : PCCP

Northey T, Norell J, Fouda AEA, Besley NA, Odelius M, Penfold TJ.
PMID: 31464301
Phys Chem Chem Phys. 2020 Feb 07;22(5):2667-2676. doi: 10.1039/c9cp03019k. Epub 2019 Aug 29.

The emergence of X-ray free electron lasers (X-FELs) has made it possible to probe structural dynamics on the femtosecond timescale. This extension of experimental capabilities also calls for a simultaneous development in theory to help interpret the underlying structure...

Regio- and conformational isomerization critical to design of efficient thermally-activated delayed fluorescence emitters.

Nature communications

Etherington MK, Franchello F, Gibson J, Northey T, Santos J, Ward JS, Higginbotham HF, Data P, Kurowska A, Dos Santos PL, Graves DR, Batsanov AS, Dias FB, Bryce MR, Penfold TJ, Monkman AP.
PMID: 28406153
Nat Commun. 2017 Apr 13;8:14987. doi: 10.1038/ncomms14987.

Regio- and conformational isomerization are fundamental in chemistry, with profound effects upon physical properties, however their role in excited state properties is less developed. Here two regioisomers of bis(10H-phenothiazin-10-yl)dibenzo[b,d]thiophene-S,S-dioxide, a donor-acceptor-donor (D-A-D) thermally-activated delayed fluorescence (TADF) emitter, are studied....

Primary Production in Antarctic Sea Ice.

Arrigo KR, Worthen DL, Lizotte MP, Dixon P, Dieckmann G.
PMID: 9103193
Science. 1997 Apr 18;276(5311):394-7. doi: 10.1126/science.276.5311.394.

A numerical model shows that in Antarctic sea ice, increased flooding in regions with thick snow cover enhances primary production in the infiltration (surface) layer. Productivity in the freeboard (sea level) layer is also determined by sea ice porosity,...
