A simple synthesis of [11C]methyl triflate
(Elsevier, 1992-11)
[11C]Methyl triflate ([11C]methyl trifluoromethanesulfonate) was formed in high yield when [11C]methyl iodide in a nitrogen carrier was passed at 200[deg]C through a column containing graphitized carbon impregnated with ...
Cross sections for dark matter particles and implications for allowed masses, interactions, and detection
(Elsevier, 1986)
We present scattering and annihilation cross sections for a number of candidates for dark matter: heavy neutrinos, photinos, scalar-neutrinos, and higgsinos. In the mass region below about 10 GeV, annihilation cross sections ...
Scalable Multiplexed Drugâ Combination Screening Platforms Using 3D Microtumor Model for Precision Medicine
(Springer New YorkWiley Periodicals, Inc., 2018-10)
Cancer heterogeneity is a notorious hallmark of this disease, and it is desirable to tailor effective treatments for each individual patient. Drug combinations have been widely accepted in cancer treatment for better ...
The 12C([alpha], n)15O and 16O([alpha], n)19Ne reactions at E[alpha] = 41 MeV
(Elsevier, 1981-06-15)
Spectra and neutron angular distributions have been obtained for the ([alpha], n) reaction on 12C and 16O to (a) determine whether with this reaction more detailed spectroscopic information can be extracted than from ...
Analysis of the inelastic scattering of 50 MeV protons
(Elsevier, 1968-09-23)
Differential cross sections and asymmetries for 50 MeV proton scattering from vibrational states in 64,66,68,70Zn and 114Cd have been analysed using a collective-model interaction obtained by deforming the entire optical ...
Efficiency and angular resolution calculations for a prototype multiple Compton scatter camera
(Elsevier, 1994-06-15)
Monte Carlo simulations were performed to optimize the layer thickness of a Compton camera which utilizes multiple Compton scatterings. The optimum layer thickness was found to be less than 0.5 mm for 150 keV, 2 mm for 511 ...
Towards Designer Microparticles: Simultaneous Control of Anisotropy, Shape, and Size
(WILEY-VCH Verlag, 2010-02-05)
Biodegradable, compositionally anisotropic microparticles with two distinct compartments that exhibit controlled shapes and sizes are fabricated. These multifunctional particles are prepared by electrohydrodynamic co-jetting ...
Digital techniques for real-time pulse shaping in radiation measurements
(Elsevier, 1994-12-30)
Recursive algorithms for real-time digital pulse shaping in pulse height measurements have been developed. The differentiated signal from the preamplifier (exponential pulse) is amplified and then digitized. Digital data ...
An image intensifier-scintillator device for determination of profiles and images of weak beams of ionizing particles or X-rays
(Elsevier, 1961)
An instrument for determining the shape and intensity distribution of particle and X-ray beams has been developed using an image intensifier tube together with a bundle of filaments of scintillator. A description of the ...
