Emulsion stability: Delineation of different particle loss mechanisms
(Elsevier, 1981-01)
The kinetics of the emulsion-breaking process are governed by three different particle loss mechanisms: Brownian flocculation, sedimentation flocculation, and creaming. Various particle loss mechanisms have been delineated ...
Spectrophotometric investigation of products formed following the initial one-electron electrochemical reduction of nicotinamide adenine dinucleotide (NAD+)
(Elsevier, 1981-12-04)
On electrolysis of NAD+ in aqueous solution at a potential corresponding to the initial one-electron reduction of NAD+ to a free radical, a greenish-yellow color appears which fades when electrolysis is complete. Literature ...
Universality and critical exponents of energy transport in binary crystals: 3B2u naphthalene
(Elsevier, 1981-01-01)
Exciton migration experiments on isotopically mixed naphthalene crystals reveal a universal behavior with reduced donor concentration, irrespective of temperature, acceptor species or acceptor concentration, giving a very ...
Crystal and molecular structure of analgesics, I. Ciramadol hydrobromide, C 15 H 23 O 2 N · HBr
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1981-08)
Dissolution kinetics: Catalysis by strong acids
(Elsevier, 1981-07)
The dissolution of silicate minerals in mixtures of hydrofluoric acid and strong acids such as HCl is catalyzed by H+ ions adsorbed at the mineral surface. Studies of the catalyzed dissolution of kaolinite, quartz, potassium ...
Activation of CTP : Phosphocholine cytidylyltransferase in rat lung by fatty acids
(Elsevier, 1981-07-24)
CTP : phosphocholine cytidylyltransferase activity exists in both the microsome and cytosol fractions of adult lung, 36 and 59%, respectively. Although these enzyme activities are stimulated in vitro by added lipid activators ...
446 -- Electrochemical examination of nucleoside interaction : Adenosine--guanosine and cytidine--guanosine
(Elsevier, 1981-10)
The adsorption at the solution/mercury electrode interface of guanosine, adenosine and cytidine alone and in guanosine--adenosine and guanosine--cytidine mixtures was examined for pH 4.0 and 7.2 solutions at 25 and 40[deg]C; ...
Electromagnetic effects on a molecule at a metal surface : I. Effects of nonlocality and finite molecular size
(Elsevier, 1981-08-02)
The electromagnetic effects on a molecule near a metal surface are considered with the view to understanding the surface-enhanced-Raman-scattering (SERS) effect. The image enhancement effect is calculated including the ...
Thermophysics of the lanthanide trihydroxides III. Heat capacities from 5 to 350 K of the related compound Y(OH)3. Lattice contribution
(Elsevier, 1981-06)
Heat-capacity measurements between 5 and 350 K have been performed upon a microcrystalline sample of Y(OH)3. The heat capacities can be represented by a simple sigmate curve; no anomalous behavior was observed. Comparison ...
N,N'-diacetylchitobionic N-alkylamides: Synthesis, and interaction with two 2-acetamido-2-deoxy--glucose-binding lectins
(Elsevier, 1981-10-16)
Condensation of N,N'-diacetylchitobiono-1,5-lactone, obtained by oxidation of N,N'-diacetylchitobiose, with n-alkylamines gave N,N'-diacetylchitobionic N-alkylamides. The interaction of these glycolipids with wheat-germ ...
