Perfluorooctanoyl modified poly(vinyl alcohol)s (FPVA) were prepared by means of substituting a small amount of hydroxyl groups on the backbone of poly(vinyl al
In this paper, we report our success in building efficient scalable classifiers by exploring the capabilities of modern relational database management systems(R
Several kinds of racemic naproxen ester were successfully separated on CTMB chiral stationary phase with hexane-ethanol (98:2, vol./vol.) as the mobile phase.
a-Bromo benzoylmethylene triphenylphosphorane 3 has been synthesized by the reaction of benzoylmethylene triphenylphosphorane 1 with N-bromosuccinimide in the y
First total synthesis of (±)-hypargenin B methyl ether 2 was accomplished via a strategy of AC→ABC, in which CrO3/H2O/NaOAc/HOAc system was utilized for intr
We cloned cDNAs for Xenopus aldolases A, B and C. These three aldolase genes are localized on different chromosomes as a single copy gene. In the adult, the ald
The reaction of ethanol with propylene oxide over calcined layered double hydroxides(CLDH) was investigated. The results show that CLDH has a good activity and
A new abietane diterpenoid, orthosiphonol (11-methoxy-12, 14-dihydroxy-8, 11, 13-abieta trien-7-one) (1) together with known 11-hydroxysugiol (2) were isolated
Thc K+ scattering cross section with the in-medium virtual pion is evaluated in the lowest-order chiralperturbation theory with the density-dependent pion decay
This paper presents new results for strong solutions and their coincidence sets of the obstacle problem for linear hyperbolic operators of first order. An inequ
