Detergent extracts of cell envelopes of the gliding bacterium Herpetosiphon aurantiacus formed channels in lipid bilayers. Fast protein liquid chromatography across a HiTrap-Q cation-exchange column demonstrated that a 45-kDa protein forms the channel. The observation of a channel-forming protein suggests that Herpetosiphon aurantiacus Hp a2 has a permeability barrier on its surface.

Washington : Government Printing Office. 1901. The collection of essays forming the general appendix of this annual report is always of most absorbing interest; and the volume before us, containing for example papers on Liquid Hydrogen, by Prof. Dewar; Psychical Research, by Sir W. Crookes; the Petrified Forests of Arizona, by Lester F. Ward, &c., &c., is if possible more fascinating than usual...

Recent measurements of nematic-smectic A pressure-temperature phase boundaries obtained in bilayer forming smectic A liquid crystals are analyzed. A thermodynamic model which accounts for the elliptical shape of the phase boundaries and which facilitates determination of the various parameters determining the phase boundary is presented and discussed.

The first compound capable of forming a bundled-stack discotic columnar liquid crystalline (BSDCLC) phase was designed and synthesized. The unique perylene anhydride inter-stack interaction was found to be the key to the formation of the BSDCLC structure and inter-stack electronic coupling (ISEC).

Mouse blood monocytes were induced to proliferate and form discrete colonies of mononuclear phagocytes in liquid culutre. The proliferation of these cells in vitro required a factor or factors present in medium conditioned by L cells. For this class of colony-forming cells, the value of Do to gamma irradiation in vitro was 195 rads.

The pore-forming microcin E492 was purified by solid-phase extraction and reversed-phase high-pressure liquid chromatography. Its molecular mass was 7,886 Da. The entire 84-amino-acid sequence was determined. There is no postranslational modification in the secreted microcin, and the sequence has homologies with the sequence of the microcin colicin V.

Highly dispersed rhodium nanoparticles (1.7 +/- 0.3 nm) prepared by a liquid-phase reduction method were loaded on a solid solution of GaN and ZnO without forming aggregates, achieving improved activity for visible-light-driven overall water splitting when the nanoparticles are coated with a chromia shell.

[1] Flow processes in unsaturated fractures considerably differ from flow in rock matrix because of the dominance of gravitational forces, accentuated by variations in fracture geometry. This gives rise to liquid fragmentation, fingering, and intermittent flow regimes that are not amenable to standard continuum representation. We develop an alternative modeling framework to describe the onset o...
