Solution-processed organic photovoltaics (OPV) offer the attractive prospect of low-cost, light-weight and environmentally benign solar energy production. The highest efficiency OPV at present use low-bandgap donor polymers, many of which suffer from problems with stability and synthetic scalability. They...

Since we do not know of any completely workable solutions to the problems we have considered, we shall settle for a few general observations: 1) The public availability of socially useful computer communications services is and has been held...

Polar substituent effects in the bicyclo[1.1.1]pentane ring system: acidities of 3-substituted bicyclo[1.1.1]pentane-1-carboxylic acids.

The Journal of organic chemistry

Adcock W, Baran Y, Filippi A, Speranza M, Trout NA.
PMID: 15675864
J Org Chem. 2005 Feb 04;70(3):1029-34. doi: 10.1021/jo040236b.

Experimental gas-phase acidities are reported for a series of 3-substituted (X) bicyclo [1.1.1]pent-1-yl carboxylic acids (1, Y = COOH). A comparison with available calculated data (MP2/6-311++G**// B3LYP/6-311+G**) reveals good agreement. The relative substituent effects are shown to be adequately...

In vivo half life of nanoencapsulated L-asparaginase.

Journal of materials science. Materials in medicine

J Mater Sci Mater Med. 2002 Dec;13(12):1113-21. doi: 10.1023/a:1021125617828.

In the present study, antileukemic enzyme L-asparaginase (ASNase) was encapsulated into poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) nanocapsules in order to decrease the immunogenicity and toxicity of the enzyme and to increase its in vivo half life in mice. Nanocapsules were prepared by...
