The faradaic admittance of electrochemical processes : III. The frequency dependence
(Elsevier, 1961)
Recent experimental studies have demonstrated the inadequacy of proposed equations for the faradaic admittance, particularly in respect to the frequency dependence. Existing treatments of the faradaic admittance can give ...
Linearized embedding: A new metric matrix algorithm for calculating molecular conformations subject to geometric constraints
(John Wiley & Sons, Inc., 1989-10)
There are many methods in the literature for calculating conformations of a molecule subject to geometric constraints, such as those derived from two-dimensional NMR experiments. One of the most general ones is the EMBED ...
CCK antagonists reveal that CCK-8 and JMV-180 interact with different sites on the rat pancreatic acinar cell CCKA receptor
(Elsevier, 1994)
The ability of CCKA antagonists to inhibit full and partial CCK agonists of the rat pancreatic acinar cell CCKA receptor has been studied. When isolated rat pancreatic acini were superfused with CCK-8 (10 pM-1 nM) or CCK-4 ...
Vapor-based polymer coatings for potential biomedical applications
(John Wiley & Sons, Ltd., 2006-12)
Over the last decade, biology and biotechnology have witnessed an extraordinary development spanning genomics, proteomics, and metabolics. This progress was so rapid and definite that it not only changed the face of modern ...
The use of silica gel impregnated glass fiber sheets in plasma estriol assays
(Elsevier, 1970)
The fluorimetric quantitation of nanogram amounts of estriol extracted from plasma is sometimes impaired by impurities which interfere with fluorescence. Instant thin-layer chromatography on silica gel impregnated glass ...
Vibrational analysis of crystalline diketopiperazine--II. Normal mode calculations
(Elsevier, 1984)
Based on our Raman and i.r. [1] data and assignments for DKP and five of its isotopic derivatives, we have refined an intramolecular force field in a non-redundant basis. This analysis shows that the cis peptide group may ...
Gellan gum–O,O′‐bis(2‐aminopropyl)‐polyethylene glycol hydrogel for controlled fertilizer release
(Academic PressWiley Periodicals, Inc., 2018-01-10)
A gellan gum–Jeffamine superabsorbent hydrogel was obtained with different crosslink densities using different amounts of (1‐ethyl‐3‐(3‐dimethylaminopropyl)carbodiimide hydrochloride) and N‐hydroxysuccinimide. Infrared ...
Engineering Specific Cross‐Links in Nucleic Acids Using Glycol Linkers
(Wiley Periodicals, Inc., 2000-02)
One of the most convenient methods for generating oligonucleotides possessing intra‐ or interstrand cross‐links is through incorporation of oligoethylene glycol bridges by solid‐phase synthesis. The reagents are commercially ...
