A practical large scale chemical synthesis of chiral glycines
(Elsevier, 1988)
(R)- and (S)-[2-2H]glycine of high chiral purity were synthesized in large quantities in [approximate] 40% overall yield from readily available starting materials via a totally chemical procedure. Reduction of either ...
Origin of Low Detection Limit and High Selectivity of Roche Accu‐Chek Test Strips that Enables Measurement of Tear Glucose Levels
(WILEY‐VCH Verlag, 2015-03)
Tear glucose measurements have been suggested as a potential alternative to blood glucose monitoring for diabetic patients. While previous work has reported a correlation between blood and tear glucose levels in humans, ...
LC‐MS/MS isomeric profiling of permethylated N‐glycans derived from serum haptoglobin of hepatocellular carcinoma (HCC) and cirrhotic patients
(Wiley Periodicals, Inc., 2017-09)
Early stage detection and cancer treatment demand the identification of reliable biomarkers. Over the past decades, efforts have been devoted to assess the variation of glycosylation level as well as the glycan structures ...
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 ...
Low-temperature heat capacities, thermophysical properties, optical spectra, and analysis of Schottky contributions to Pr(OH)3
(Elsevier, 1979-09)
From values of the heat capacity of microcrystalline Pr(OH)3 determined by precise adiabatic calorimetry from 15 to 350 K, the Schottky contribution associated with all but the lowest Stark level was resolved with the aid ...
