A new method for the synthesis of 3-N-phthaloyl homophenylalanine lactone has been developed and its mechanism was proposed
Iterative algorithms for solving the data assimilation problems are considered, based on the main and adjoint equations. Spectral properties of the control oper
The static adsorption performances of a series of active carbon fiber (ACF)for xenon at 201 K were measured with a model ASAP2010M specific surface area and ape
Synthesis and Crystal Structure of Complex: [Co(cdm)2(H2O)4] 2H2O(cdm = Carbamyldicyanomethanide Ani
Mononuclear complex [Co(cdm)2(H2O)4]@2H2O was synthesized by sodium carbamyldicyanomethanide (Nacda) and cobalt perchlorate. The crystal belongs to monoclinic s
The surface modification of nanometer carbon material has been studied by usingan Induced Dielectric Barrier Discharge Plasma device (IDBD). The experimentalres
