High-frequency coils are widely used in medical applications, such as Magnetic Resonance Imaging (MRI) systems. A typical medical MRI includes a local radio frequency transmit/receive coil. This coil is designed for maximum energy transfer or wave transfer through magnetic resonance. Mutual inductance is a dynamic parameter that determines the energy quantity to be transferred wirelessly by ele...

Compost product safety and quality assurance are required to meet the needs of the horticultural, agricultural, and silvicultural user markets. At present, there exist no industry-wide sampling and testing protocols for compost products, thus limiting the production sector. The objective of this research was to test three methods for determining compost maturity. The study followed the composti...

Photochemical transformations of methyl coumalate have been studied by matrix-isolation technique. Two photoreactions were induced by UV (k > 295 nm) light: isomerisation to the Dewar form and a-bond cleavage leading to the open-ring aldehyde-ketene. The first photoprocess was found to be strongly dominating. Experimental evidence of photoreversibility of both photoisomerisation processes has b...

in this paper, we propose and evaluate a novel design of a lightly doped drain and source carbon nanotube field effect transistor (ldds-cntfet) with a negative differential resistance (ndr) characteristic, called negative differential resistance ldds-cntfet (ndr-ldds-cntfet). the device was simulated by using a non equilibrium green’s function method. to achieve this phenomenon, we have created...

Our goal is to extend the sensitivity of field cycling pure quadrupole resonance (PQR) methods to be of use in biological systems. The nuclei of interest are 2 5 Mg, 6 7 Zn, 4 3 Ca, n B and 1 7 0 . The experiment is based on a field cycling double resonance technique, in which the quadrupole resonance of a rare nucleus is found through its effect on the magnetic order of the abundant nucleus to...

Experimental A stainless steel ultra high vacuum (UHV) chamber, pumped by a turbo molecular pump backed by a mechanical pump, providing a base pressure of 5X10 torr after bake out, was used for temperature programmed desorption (TPD) experiments with a typical heating rate of 2.5 K/s. Samples could be cooled below 100 K via a liquid nitrogen dewar and heated up to 1300 K via resistive heating. ...

Dewar benzene, one of the isolable valence isomers C6H6, has been extensively studied since its first synthesis in 1962. By contrast, chemistry inorganic congeners which can be formally gained by replacing skeletal carbon atoms with heteroatoms, less developed despite their peculiar structural and electronic features. Among them, extant B,N-Dewar benzenes are limited to B3N3 system. Herein, we ...

Density functional theory methods(DFT) and natural bond orbital (NBO) analysis were used to investigate the effects of isomerism and side chain mutation at a microscopic level on the stability, binding energy and NMR/NQR tensors of structural isomers, L- methionylasparagine (Met-Asn) and L- asparagylmethionine (Asn-Met) in the gas phase. The results represented that the isomerism and side chain...
