Adhesion at a heterophase interface: First-principles study of Mo(001)/MoSi 2 (001)
(Kluwer Academic Publishers; Springer Science+Business Media, 1994-09)
The bonding characteristics, interfacial energetics, and electronic structure associated with adhesion at the Mo-MoSi 2 (001) heterophase interface are investigated using the first-principles, self-consistent local orbital ...
H2O2-Induced Increases in Cellular F-Actin Occur without Increases in Actin Nucleation Activity
(Elsevier, 1994-02)
Previous work has shown that H2O2 causes an increase in polymerized actin (F-actin) inside cells. To test the hypothesis that increased polymerization resulted from a mechanism involving increased actin nucleation activity, ...
Molybdenum nitride catalysts : I. Influence of the synthesis factors on structural properties
(Elsevier, 1994-03)
Effects of the synthesis parameters on the structural properties of molybdenum nitride catalysts, prepared by the temperature-programmed reaction of MoO3 with NH3, have been examined. Molybdenum trioxide was heated in ...
Synthesis of a disulfide stabilized RNA hairpin
(Elsevier, 1994-03-14)
An N-3 ethylthiol-modified uridine has been synthesized and incorporated through solid-phase phosphoramidite chemistry at the 5'- and 3'-termini of an RNA hairpin to provide increased conformational stability via a disulfide ...
Generation of 2-azapentadienyl anions and their cycloaddition with alkenes. Synthesis of 2-alkenylpyrrolidines
(Elsevier, 1994-09-19)
[alpha],[beta]-Unsaturated imines 2 bearing an N-[1-(tri-n-butylstannyl)]alkyl group were transmetalated with n-BuLi to generate 2-azapentadienyl anions 3 which underwent [4[pi]s+2[pi]s] anionic cycloadditions with alkenes ...
Palladium- and platinum-catalyzed coupling reactions of allyloxy aromatics with hydridosilanes and hydridosiloxanes: Novel liquid crystalline/organosilane materials
(John Wiley & Sons, Inc., 1994-12)
Pt-and Pd-catalyzed reactions of a set of allyloxyaromatic mono-and diesters with selected silanes were examined to develop simple, mild methods of forming liquid crystal (LC)/ siloxane and LC/silsesquioxane polymers. Pt ...
Immunohistochemical localization of the kappa1 opioid receptors
(Elsevier, 1994-11-10)
Using antibodies generated to the C-terminal 41 amino acids of the cloned rat kappa receptor, the present study examines the distribution of the kappa1 receptor-like immunoreactivity (li) using immunohistochemical techniques. ...
Bone Marrow Transplantation Demonstrates That Carbonic Anhydrase II Deficiency Limited to Bone Marrow-Derived Cells Affects Ammonium Chloride Tolerance in Mice
(Elsevier, 1994-02)
Bone marrow transplantation (BMT) in mice was utilized to determine the relative importance of carbonic anhydrase II (CA II) deficiency in blood compared to kidney in the pathogenesis of the ammonium chloride intolerance ...
Thermodynamics of the thallium alkanoates VIII. Heat capacity and derived thermophysical properties of thallium(I) propanoate and pentanoate at temperatures from 6 K to 490 K
(Elsevier, 1994-09)
Heat-capacity measurements by adiabatic calorimetry at temperature T = 5 K to 350 K were supplemented by differential-scanning calorimetry (d.s.c.) into the liquid region on thallium(I) propanoate and pentanoate. Apparent ...
Fatigue craze initiation in polycarbonate: study by transmission electron microscopy
(Elsevier, 1994-08)
Fatigue craze initiation in bulk, amorphous polycarbonate (PC) is investigated by means of transmission electron microscopy. The results agree very well with small angle X-ray scattering measurements of the same set of ...
