This is crucial in supramolecular chemistry, which often involves highly sophisticated and synthetically costly building blocks. The small size of the microfluidic structure is crucial in bringing the time scale for kinetic monitoring down to seconds. At the same time, the transmission line NMR probe provides sufficient sensitivity to work at low(2 m M) concentrations.

The non-relativistic radial Schr¨odinger equation is analytically solved using asymptotic iteration method within the framework of a general interaction potential whose special cases are the Cornell and Cornell plus harmonic potentials. The energy eigenvalues expression is derived in three dimensional space, which is further used to calculate the mass spectra of ˉcc,ˉbb,ˉbc, cˉs, bˉs and b ˉq mesons. The obtained results of this work are in good agreement with experimental and other relativistic results and also improved in comparison with other non-relativistic recent studies.

In order to achieve small size,light weight,and immunity to electromagnetic interference,it is desirable to replace bulky coaxial cables with optical fiber in advanced radar *** applications require a large dynamic range that is beyond the reach of conventional intensity modulation–direct detection fiber-optic links.A coherent fiber-optic link employing an optical phase-locked loop(OPLL)phase demodulator has been proposed as a solution to this *** challenge is the practical realization of the OPLL demodulator that satisfies the stringent loop delay requirement.A novel attenuation counterpropagating(ACP)OPLL concept has been proposed and demonstrated as a *** this paper we review the recent progress in realizing chip-scale ACP-OPLL *** particular,we focus on the latest measurement results achieved using a hybrid integrated ACP-OPLL,as well as the design and performance potential of a monolithically integrated ACP-OPLL photonic integrated circuit.
