Ultrafast Raman Spectroscopy as a Probe of Local Structure and Dynamics in Photoexcited Conjugated Materials.

The journal of physical chemistry letters

Bragg AE, Yu W, Zhou J, Magnanelli T.
PMID: 27681200
J Phys Chem Lett. 2016 Oct 06;7(19):3990-4000. doi: 10.1021/acs.jpclett.6b01060. Epub 2016 Sep 28.

An important challenge in the study of conjugated organic materials is to relate the properties of transient states underlying macroscopic material responses directly with intra- and intermolecular structure. We discuss recent efforts using the vibrational sensitivity of time-resolved Raman...

Ultrafast photo-induced nuclear relaxation of a conformationally disordered conjugated polymer probed with transient absorption and femtosecond stimulated Raman spectroscopies.

The Journal of chemical physics

Yu W, Donohoo-Vallett PJ, Zhou J, Bragg AE.
PMID: 25084903
J Chem Phys. 2014 Jul 28;141(4):044201. doi: 10.1063/1.4890326.

A combination of transient absorption (TAS) and femtosecond stimulated Raman (FSRS) spectroscopies were used to interrogate the photo-induced nuclear relaxation dynamics of poly(3-cyclohexyl,4-methylthiophene) (PCMT). The large difference in inter-ring dihedral angles of ground and excited-state PCMT make it an...

Desymmetrization of a meso-diol complex derived from [Cr(CO)3(eta6-5,8-naphthoquinone)]: use of new diamine acylation catalysts.

Chemical communications (Cambridge, England)

Kündig EP, Lomberget T, Bragg R, Poulard C, Bernardinelli G.
PMID: 15216374
Chem Commun (Camb). 2004 Jul 07;(13):1548-9. doi: 10.1039/b404006f. Epub 2004 May 21.

[Cr(CO)3(naphthoquinone)](1), prepared in a three-step sequence starting from 1,4-dihydroxynaphthalene, was reduced to the corresponding meso-dihydronaphthalene syn-diol complex and the latter was desymmetrized to give the mono-acyl complex with 99% ee via asymmetric acylation catalyzed by the two new and...

Magnetic resonance-guided focused ultrasound surgery (MRgFUS) treatment for uterine fibroids.

Biomedical imaging and intervention journal

Abdullah B, Subramaniam R, Omar S, Wragg P, Ramli N, Wui A, Lee C, Yusof Y.
PMID: 21611036
Biomed Imaging Interv J. 2010 Apr-Jun;6(2):e15. doi: 10.2349/biij.6.2.e15. Epub 2010 Apr 01.

Magnetic Resonance-guided focused Ultrasound Surgery (MRgFUS) is gaining popularity as an alternative to medical and surgical interventions in the management of symptomatic uterine fibroids. Studies have shown that it is an effective non-invasive treatment with minimal associated risks as...

Participant-Centric Initiatives: Tools to Facilitate Engagement In Research.

Applied & translational genomics

Anderson N, Bragg C, Hartzler A, Edwards K.
PMID: 24772384
Appl Transl Genom. 2012 Dec 01;1:25-29. doi: 10.1016/j.atg.2012.07.001.

Clinical genomic research faces increasing challenges in establishing participant privacy and consent processes that facilitate meaningful choice and communication capacity for longitudinal and secondary research uses. There are an evolving range of participant-centric initiatives that combine web-based informatics tools...

Minilaparoscopic sacrocolpopexy for vaginal prolapse after hysterectomy.

Surgical technology international

Ferreira H, Ferreira C, Braga A, Pereira AT, Guimaraes S.
PMID: 25433151
Surg Technol Int. 2014 Nov;25:157-61.

Genital prolapse repair is one of the most common indications for benign gynecologic surgery. The lifetime risk of undergoing a single operation for prolapse in the female population is rising. Many different surgical techniques have been described. We report...
