Intelligent resource usage is one of the most challenging tasks for the wood-based panels industry. With respect to this issue, leather shavings, derived during leather preparation, are a promising new raw material, as they offer not only high availability, but also potentially enhance material properties such as panel fire retardancy. In order to improve the performance of these emerging panel...

MR offers unique tools for measuring molecular diffusion. This review focuses on the use of diffusion-weighted MR spectroscopy (DW-MRS) to non-invasively quantitate the translational displacement of endogenous metabolites in intact mammalian tissues. Most of the metabolites that are observed by in vivo MRS are predominantly located in the intracellular compartment. DW-MRS is of fundamental inte...

Nuclear magnetic resonance (NMR) spectroscopy uses the magnetic spin properties of atomic nuclei within a molecule to identify atoms that are close together in space (either because they are bonded together or because folds of a protein chain bring them together). This information is used to derive a three-dimensional model of a protein in solution (a ‘solution structure’). Only certain isotope...

[This paper is a commentary on the paper Distinguishing multiple chemotaxis Y protein conformations with laserpolarized Xe NMR by Lowery et al. in this issue.] The present contribution highlights a remarkable progress in biomolecular NMR spectroscopy. The xenon isotope Xe is an NMR active spin-1/2 nucleus. It has been introduced into surface NMR spectroscopy by Ito and Fraissard (1982). Since t...

A new scheme is proposed to edit separately glutamate C(3) and C(4) resonances of (1)H bound to (13)C, in order to resolve these two signals which overlap at intermediate magnetic fields (1.5 T-3 T), commonly available for human brain studies. The two edited spectra are obtained by combining the individual acquisitions from a four-scan measurement in two different ways. The four acquisitions co...

Among the different forms of spectroscopy, nuclear magnetic resonance (NMR) shows an intimate connection between theory and experiment. NMR therefore enjoys great popularity in the development of new methods. Following the rapid development in electronic and computer technology, NMR techniques evolved from singlechannel to multi-channel and multi-dimensional modes. The original continuous wave ...

A number of arylamides have been synthesized and found to exhibit potent antimicrobial activities against a broad spectrum of Gram-positive and Gram-negative bacteria while exhibiting low toxicity toward eukaryotic cells. These facially amphiphilic foldamers have a relatively rigid intramolecular hydrogen-bonded arylamide as a framework, which places trifluormethyl versus positively charged ami...

in this paper, we report the synthesis and characterization of a new symmetric macroacyclic schiff base ligand (h2l) and related complexes with different metals. (h2l) was synthesized by the one pot condensation reaction of 2-[2-(2-formyl phenoxy)ethoxy]benzaldehyde and 2-aminobenzenethiol in a 1:2 molar ratio. the acyclic schiff base was characterized by ir, nmr spectroscopy and elemental anal...

molecular tumbling causes that anisotropy of nuclear interaction now plays dominant role in the appearance of NMR spectra. Frankly speaking the NMR signals are very broad and spectra become featureless. In general missing isotropic tumbling leads to severe broadening of the detected signals. The lack of resolution, however; does not mean the absence of structure information, it rather reflects ...
