Increasing Thyromimetic Potency through Halogen Substitution

Halogen transfer through halogen bonds in halogen-bound ammonia homodimers.

Ab initio MP2(full)/aug-cc-pVTZ calculations have been carried out to investigate the halogen transfer between haloamines and ammonia. The results show that the formation of a halogen bond complex between ammonia and the protonated N-haloamine is a preliminary step in the halogen transfer process. The complexation energies, optimized geometries, topology of electron density and potential energy...

Halogen-substitution effect on the optical absorption bands of uracil.

The ultraviolet absorption spectra of uracil and its 5-halogenated derivatives have been in­ vestigated in regard to the electron attracting properties of the substituents. It could be shown that the position of the two absorption bands is proportional to the inverse of the electronegativity; the extinction coefficients are a linear function of the electron affinities. In this way, the red shif...

Increasing Mn substitution in magnetic semiconductors through controlled ambient annealing processes

We report on a controlled ambient annealing technique aimed at increasing the amount of Mn incorporation in III–V semiconductors. The aim is to reduce the number of hole carrier and magnetic element compensating entities, such as Mn interstitials and anti-site defects, to increase the magnetic Curie temperature. The idea is (a) to increase the number of Group III vacancies through annealing in ...

Thawing Sperm of Sheep Towards Increasing Potency of Spermatozoa

The development of cattle population in Indonesia has not reached in happy condition, even in east Java in the 2001 was decreasing population of some cattle, such as sheep 3,24 %, cow 5,86% and buffalo 5% whereas other cattle have increased far from our hope. (Anonymous, 2007). The obstacle which is faced in the cattle breeding field is involving reproduction field, the priority fertilization p...
