Tetrabutylphosphonium hydroxide containing 40 wt% water dissolved 20 wt% cellulose at the final concentration within 5 minutes under mild stirring at 25 °C.

The structures of core-links Al(13) (C-Al(13)) and flat-Al(13) (F-Al(13)) complexes in aqueous solution have been investigated using density functional theory (DFT) at the level of B3LYP/6-31G(d). The present work focuses on the following three aspects: (1) C-Al(13)(9+) was optimized with the consideration of solvent effect and the (27)Al NMR chemical shifts using Hartree Fock GIAO and B3LYP GI...

A terminal and unsupported chromium(III) hydroxide is reported. The terminal hydroxide is used to synthesize the first example of a heterobimetallic Ti-O-Cr compound containing an unsupported μ-oxo bridge. The heterobimetallic complex exhibits a new absorbance at 288 nm (4.32 eV), which is assigned to a metal-to-metal charge transfer (MMCT) transition.

3T3 cells are shown to reduce SV40-3T3 cell population growth in a denisty-dependent manner in co-cultures of 3T3 and SV40-3T3 cells. The development of this inhibitory activity roughly parallels the development of density-dependent inhibition of growth in homogeneous 3T3 control cultures. The extent of reduction of SV40-3T3 growth can be manipulated by pretreatment of 3T3 cells with a high ser...

to the operation the patient is too much meddled with. After the usual dark-room examination the pa'.ient is put to bed, given a purge, the eye lashes and eye-briow shaved, an antiseptic dressing applied the night before operation. A weak solution of cocaine is used for the operation and several drops are put in the eye at intervals of ten mfinutes before the operation. The patient .is then bro...
