Ligand effects in a Heteroleptic bis-Tridentate Iron (III) Spin Crossover Complex showing a Very High T1/2 Value

01-Dec-2015 | Keith S. Murray; Wasinee Phonsri; Victor Martinez; Casey G Davies; Guy N L Jameson; Boujemaa Moubaraki, Chemical Communication, 2015

We describe the first example of a bis-tridentate heteroleptic iron(III) spin crossover (SCO) complex, [Fe(3-OMe-SalEen)(thsa)].Compared to the parent homoleptic compounds, the spin crossover features in the heteroleptic species are enhanced with a gradual- abrupt spin transition at 344 K. Clear ...


Particle Size Measurement from Infrared Laser Ablation of Tissue

25-Nov-2015 | Fan Cao; Fabrizio Donnarumma; Kermit K Murray, Analyst, 2015

The concentration and size distribution were measured for particles ablated from tissue sections using an infrared optical parametric oscillator laser system. A scanning mobility particle sizer and light scattering particle sizer were used in parallel to realize a particle sizing range from 10 nm ...


Quantifying “Softness” of Organic Coatings on Gold Nanoparticles Using Correlated Small-Angle X-ray and Neutron Scattering

20-Nov-2015 | Benjamin T. Diroll; Katie M. Weigandt; Davit Jishkariani; Matteo Cargnello; Ryan J. Murphy; Lawrence A. Hough; Chris ..., Nano Letters, 2015

Small-angle X-ray and neutron scattering provide powerful tools to selectively characterize the inorganic and organic components of hybrid nanomaterials. Using hydrophobic gold nanoparticles coated with several commercial and dendritic thiols, the size of the organic layer on the gold particles ...


Steroid-Derived Naphthoquinoline Asphaltene Model Compounds: Hydriodic Acid Is the Active Catalyst in I2-Promoted Multicomponent Cyclocondensation Reactions

20-Nov-2015 | Matthias Schulze; David E. Scott; Alexander Scherer; Frank Hampel; Robin J. Hamilton; Murray R. Gray; Rik R. Tykwins ..., Organic Letters, 2015

Organic Letters DOI: 10.1021/acs.orglett.5b03193


Comparison of Asian Aquaculture Products by Use of Statistically Supported Life Cycle Assessment

20-Nov-2015 | Patrik J. G. Henriksson; Andreu Rico; Wenbo Zhang; Sk. Ahmad-Al-Nahid; Richard Newton; Lam T. Phan; Zongfeng Zhang; ..., Environmental Science & Technology, 2015

We investigated aquaculture production of Asian tiger shrimp, whiteleg shrimp, giant river prawn, tilapia, and pangasius catfish in Bangladesh, China, Thailand, and Vietnam by using life cycle assessments (LCAs), with the purpose of evaluating the comparative eco-efficiency of producing different ...


Corrigendum: Regulatory analysis of the C. elegans genome with spatiotemporal resolution

17-Nov-2015 | Carlos L. Araya; Trupti Kawli; Anshul Kundaje; Lixia Jiang; Beijing Wu; Dionne Vafeados; Robert Terrell; Peter Weiss ..., Nature, 2015

Weissdepp, Louis Gevirtzman, Daniel Mace, Wei Niu, Alan P. Boyle, Dan Xie, Lijia Ma, John I. Murray, Valerie Reinke, Robert H. Waterston & Michael Snyder ...


Stochastic electrotransport selectively enhances the transport of highly electromobile molecules [Applied Biological Sciences]

17-Nov-2015 | Sung-Yon Kim; Jae Hun Cho; Evan Murray; Naveed Bakh; Heejin Choi; Kimberly Ohn; Luzdary Ruelas; Austin Hubbert; Meg ..., Proceedings of the National Academy of Sciences current issue, 2015

Nondestructive chemical processing of porous samples such as fixed biological tissues typically relies on molecular diffusion. Diffusion into a porous structure is a slow process that significantly delays completion of chemical processing. Here, we present a novel electrokinetic method termed ...


Structure–Activity Relationships of the Peptide Kappa Opioid Receptor Antagonist Zyklophin

16-Nov-2015 | Anand A. Joshi; Thomas F. Murray; Jane V. Aldrich, Journal of Medicinal Chemistry, 2015

The dynorphin (Dyn) A analogue zyklophin ([N-benzyl-Tyr1-cyclo(d-Asp5,Dap8)]dynorphin A(1–11)NH2) is a kappa opioid receptor (KOR)-selective antagonist in vitro, is active in vivo, and antagonizes KOR in the CNS after systemic administration. Hence, we synthesized zyklophin analogues to explore ...


Sorption equilibrium and kinetics for cyclohexane, toluene and water on Athabasca oilsands solids

09-Nov-2015 | Xiaoli Tan, Lisa Vagi, Qi Liu, Phillip Choi, Murray R. Gray, The Canadian Journal of Chemical Engineering, 2015

Abstract The sorption of solvents from the vapour phase to solid substrates is important in producing heavy oil and bitumen, particularly from the oilsands. We investigated the sorption and desorption equilibrium and kinetics of cyclohexane, toluene, and water on kaolinite, fine solids, and ...


Opportunity Knocks: Organic Chemistry for Fragment‐Based Drug Discovery (FBDD)

03-Nov-2015 | Christopher W. Murray, David C. Rees, Angewandte Chemie International Edition, 2015

What’s a good fragment? Fragment‐based drug discovery is well‐established within many pharmaceutical, biotech and academic institutions for generating new drugs. In this Essay, the opportunities and challenges for organic chemists to design and synthesise new fragments are described.
