(3R)-Chiral Control of 3-Alkyl-3-hydroxy-beta-lactams via Addition Reaction of Imines to Enolates of 1,3-Dioxolan-4-ones.

The Journal of organic chemistry

Barbaro G, Battaglia A, Guerrini A, Bertucci C.
PMID: 11674534
J Org Chem. 1999 Jun 25;64(13):4643-4651. doi: 10.1021/jo9822481.

A method is described for the chiral construction of (3R)-3-alkyl-3-hydroxy-beta-lactams in a versatile and predictable manner. This protocol follows Seebach's synthetic principle of self-regeneration of stereocenters and has been applied to addition reactions among a selected number of imines...

Local self-consistent approach to the phase transition at the nematic liquid-crystal-wall interface.

Physical review. E, Statistical, nonlinear, and soft matter physics

Barbero G, Evangelista LR.
PMID: 11909082
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Mar;65(3):031708. doi: 10.1103/PhysRevE.65.031708. Epub 2002 Feb 12.

The nematic-isotropic transition for a semi-infinite sample is analyzed by means of the Maier-Saupe theory. The effect of a delocalized surface field acting on the nematic molecules, and of the incomplete interaction between the nematic molecules, are taken into...

Statistical approach to the orienting photopolymer-nematic-liquid-crystal anchoring energy.

Physical review. E, Statistical, nonlinear, and soft matter physics

Alexe-Ionescu AL, Barberi R, Iovane M, Ionescu AT.
PMID: 11800703
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Jan;65(1):011703. doi: 10.1103/PhysRevE.65.011703. Epub 2001 Dec 13.

A statistical approach for the nematic order on an orienting photopolymer, also taking into account the surface anisotropy, has been formulated in the framework of mean field theory. This approach gives a Boltzmann-type orientational distribution function depending on both...

Predicting patient follow-through on telephone nursing advice.

Clinical nursing research

Valanis BG, Gullion CM, Moscato SR, Tanner C, Izumi S, Shapiro SE.
PMID: 17634354
Clin Nurs Res. 2007 Aug;16(3):251-69. doi: 10.1177/1054773807303055.

Although use of telephone advice nursing services continues to grow, little research has addressed factors that affect crucial call outcomes like follow-through on the advice given. This article describes aspects of the advice call process and examines predictors of...

Synthesis, characterization and analytical application of a new inorganic cation exchanger-Titanium(IV) molybdophosphate.

Talanta

Yavari R, Ahmadi SJ, Huang YD, Khanchi AR, Bagheri G, He JM.
PMID: 19064109
Talanta. 2009 Jan 15;77(3):1179-84. doi: 10.1016/j.talanta.2008.08.026. Epub 2008 Sep 04.

A novel polyoxometalate-cation exchanger, titanium(IV) molybdophosphate (TMP) has been synthesized under varying conditions. The material was characterized by X-ray diffraction, infrared spectroscopy, inductively coupled plasma and thermogravimetry techniques. Its stability was investigated in water, dilute acids, alkaline solutions, and...

Effective screening length of isotropic liquid samples submitted to an applied voltage.

The journal of physical chemistry. B

Zola RS, Evangelista LR, Barbero G.
PMID: 16706481
J Phys Chem B. 2006 May 25;110(20):10186-9. doi: 10.1021/jp060663o.

A cell of isotropic liquid in the shape of a slab of thickness d and containing ionic impurities is considered. It is shown that the screening effect produced by the ionic charges on the external field is characterized by...

Synthesis of boron-iodinated o-carborane derivatives. Water stability of the periodinated monoprotic salt.

Inorganic chemistry

Teixidor F, Barberà G, Viñas C, Sillanpää R, Kivekäs R.
PMID: 16634579
Inorg Chem. 2006 May 01;45(9):3496-8. doi: 10.1021/ic060124y.

Boron periodination of o-carborane has been achieved by taking account of the fact that B atoms in the cluster are of two types, i.e., those adjacent to both C atoms and the remainder. The high number of nonequivalent leaving...

Role of the adsorption phenomenon on the ionic equilibrium distribution and on the transient effects in electrolytic cells.

The journal of physical chemistry. B

J Phys Chem B. 2006 Sep 14;110(36):17889-97. doi: 10.1021/jp062271n.

We analyze the influence of the adsorption of ions at the interfaces on the transient phenomena occurring in an electrolytic cell submitted to a steplike external voltage. In the limit of small amplitude of the applied voltage, where the...
