Microcrystals of lithium octa-n-butoxynaphthalocyanine (LiNc-BuO) in a bio-compatible and oxygen-permeable polymer matrix of poly-dimethyl-siloxane (PDMS) can be used for repetitive non-invasive imaging of oxygen in live specimens by means of mm-scale electron spin resonance (ESR) imaging. This probe denoted as "oxychip" was characterized by high-resolution mum-scale ESR microcopy to reveal the...

In the accompaning Letter [ I] we have described successful FT-ESR imaging experiments utilizing pulsed field gradients. It was shown that the phase encoding method is the preferred one, and it yields spectral-spatial images of a quality comparable to the best cw-ESR spectral-spatial images even though it is only at an early stage of development. The realization of these FT-ESR imaging experime...

The Nickel(II) and Copper(II) complexes of Uramido Benzoic acid were prepared and characterized by magnetic studies, molar conductance studies, thermal analysis and spectroscopic techniques (FTIR, UV and ESR). The IR spectral studies revealed that the Uramido Benzoic acid behaves as a tridentate ligand. Electronic spectral studies and magnetic studies suggest that the complexes are in octahedra...

satellite imagery was used as a rapid and spatially explicit method to delineate crop residue cover and to estimate the use and intensity of conservation tillage. the potential of multispectral high-spatial resolution of worldview-2 local data was evaluated using 11 satellite spectral indices and linear spectral unmixing analysis (lsua). experimental plots were examined; residue cover was measu...

Combinatorial techniques which provide information on intensity and signal patterns for NMR and ESR spectra are reviewed. It is shown that these techniques can be applied to both I3C and proton NMR of molecules as well as to predict the hyperfine pattern in the ESR spectra of complex polyatomic radicals.

This paper proposes a novel method based on Spectral Regression (SR) for efficient scene recognition. First, a new SR approach, called Extended Spectral Regression (ESR), is proposed to perform manifold learning on a huge number of data samples. Then, an efficient Bag-of-Words (BOW) based method is developed which employs ESR to encapsulate local visual features with their semantic, spatial, sc...

The technique of pulsed Fourier transform NMR spectroscopy is well developed and understood. The equivalent technique for ESR has been slower to be developed, but recent developments in ESR instrumentation have now made FT ESR possible. In this paper we consider the requirements for rotating the magnetization associated with an ESR spectrum by a microwave pulse. In addition, techniques for reco...

The first two-dimensional Fourier-transform electron spin resonance (2D-FT-ESR) studies of nitroxide-labeled lipids in membrane vesicles are reported. The considerable enhancement this experiment provides for extracting rotational and translational diffusion rates, as well as orientational ordering parameters by means of ESR spectroscopy, is demonstrated. The 2D spectral analysis is achieved us...
