A Novel Route to Synthesize Nano-crystalline Ba0.5Sr0.5Co0.8Fe0.2O3-δ Perovskite Oxide at High Tempe
It is normally difficult to prepare nano-sized Ba0.5Sr0.5Co0.8Fe0.2O3-δ(BSCF) oxide at high temperature due to its high surface activity. The complexing proces
The first total synthesis of natural 6β-cinnamoyloxy-1α-hydroxy-5, 10-bis-epieudesm-4-en-3-one (1), a highly complex natural eudesmane, was described.
For a V-type three-level atomic system with two closely spaced upper levels, we investigate the light pulse propagation properties with only one laser field. Du
Background The advent of wavefront technology in the past five years has provided some insight into the optical outcomes of cataract surgery. The Tecnis Z9001 i
Based on the global color symmetry model (GCM), a method for obtaining the quark loop effects on the dressed gluon propagator in GCM is developed. In the chiral
The N-component Bariev model for correlated hopping with open boundary conditions in one dimension is studied in the framework of coordinate Bethe ansatz method
Synthesis and Properties of Biodegradable Copolymers of 9-Phenyl-2,4,8,10-tetraoxaspiro-[5,5]undcane
Novel biodegradable copolymer poly(CC-co-EEP) was synthesized by ring-opening copolymerization of cyclic carbonate 9-phenyl-2, 4, 8, 10-tetraoxaspiro-[5, 5]undc
Differential reactivity of mouse monoclonal anti-HBs antibodies with recombinant mutant HBs antigens
AIM: To investigate the reactivity of a panel of 8 mouse anti-hepatitis B surface antigen (HBsAg) monoclonal antibodies (mAbs) using a collection of 9 recombina
Methyl 12-bromo-13,14-furoxan-deisopropyldehydroabietate, C18H22BrN2O4, has been synthesized and characterized by IR, 1H NMR, 13C NMR and single-crystal X-ray d
The elastic scattering ofp-14Be system at Elab = 200 MeV is evaluated within the relativistic impulse approximation. We discuss the effects of the halo neutrons
