Acid- and base-treated Fe 3+ -TiO 2 -pillared clays for selective catalytic reduction of NO by NH 3
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-03)
Fe 3+ -ion-exchanged delaminated pillared clays (PILCs) have been found previously to be more active than the vanadia-based catalysts for selective catalytic reduction (SCR) of NO by NH 3 . The effects of acid treatment ...
Pharmacophore elements of the TIPP class of delta opioid receptor antagonists
(Kluwer Academic Publishers; ESCOM Science Publishers B.V. ; Springer Science+Business Media, 1994-10)
A series of tri-and tetrapeptides sharing the amino-terminal dipeptide unit Tyr-Tic, found in the high-affinity delta opioid receptor antagonist Tyr-Tic-Phe-Phe (TIPP), was prepared and evaluated in receptor binding assays ...
Immunocytochemistry of sequence-related neuropeptides in Drosophila
(Elsevier, 1993-06)
Based on structure, activity, and expression, the Drosophila drosulfakinin I peptide (DSK I; FDDY(OSO3H)GHMRFamide) is similar to the vertebrate peptide, cholecystokinin.1 Dromyosuppressin (DMS; TDVDHVFLRFamide) is an ...
Preparation of barium strontium titanate powder from citrate precursor
(John Wiley & Sons, Ltd., 1999-05)
TiCl 4 or titanium isopropoxide reacted with citric acid to form a titanyl citrate precipitate. Barium strontium citrate solutions were then added to the titanyl citrate reaction to form gels. These gels were dried and ...
Thermodynamic properties of tungsten ditelluride (WTe2) I. The preparation and lowtemperature heat capacity at temperatures from 6 K to 326 K
(Elsevier, 1992-06)
The heat capacity of the dichalcogenide: tungsten ditelluride, WTe2, was measured over the temperature range 5.5 T/K Cp m occurs in the region 92 T/K Sm = (0.10±0.02) · R. The anomaly coincides with the ...
Specific steroid response from a nonspecific DNA element
(Elsevier, 1994-06)
A fundamental dilemma of steroid hormone regulation is how specific transcription is attained in vivo when several receptors recognize the same DNA sequence in vitro. We have identified an enhancer of the mouse sex-limited ...
Enzymatic synthesis of sialyl Lex and derivatives based on a recombinant fucosyltransferase
(Elsevier, 1991)
A recombinant human Lewis [alpha](1,3/1,4)fucosyltranferase has been studied for its acceptor substrate specificity and used in the synthesis of sialyl Lex and derivatives.
Effect of fixation temperature on flow cytometric measurement of intracellular antibody content of hybridomas during batch culture
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1993-04)
In order to investigate the effect of fixation temperature on flow cytometric measurement of intracellular antibody content of hybridoma cells, cells in different growth stages during a batch culture were fixed and stored ...
