In-situ analysis of volatiles obtained by catalytic cracking of polyethylene with HZSM-5, HY, and HMCM-41 /
(2002)
When polymer/catalyst samples are heated in hydrogen, the extent of hydrogenation is reflected by reduced residue content and variations in Ea versus temperature curves. The addition of platinum increases volatile aromatic ...
Studies on selected enzymes of the alpha-aminoadipate pathway for lysine biosynthesis in Saccharomyces cerevisiae.
(2005)
Homocitrate synthase (HCS) catalyzes one of the regulated steps of the alpha-aminoadipate pathway for Lys biosynthesis in fungi. His-tagged HCS from Saccharomyces cerevisiae was purified to about 98% using a Ni-NTA resin ...
Synthesis and characterization of stannoles.
(1980)
Treatment of the diiodotetraphenylstannole with excess lithium cyclopentadiene results in lithium 1,1-dicyclopentadienyl-1-iodo-2,3,4,5-tetraphenylstannole which, along with its bromine analog, are the only lithium salts ...
Low-molecular-weight branched polyethylenimines: Multifunctional beta-lactam potentiators against resistant Gram-negative pathogens
(2022-05-13)
Antibiotic resistance is a simmering threat to the global public health system. Currently, it is estimated by the Centers for Disease Control and Prevention that at least 2.8 million people in the US get infected with ...
Electrode materials for lithium rechargeable batteries: Synthesis, spectroscopic studies and electrochemical performance.
(1997)
Three distinct $\rm Li\sb{x}V\sb2O\sb5$ phases, $\delta, \ \varepsilon, $ and $\gamma$-$\rm Li\sb{x}V\sb2O\sb5, $ were obtained through a chemical intercalation reaction and solid state reactions. Infrared and Raman spectra ...
Development and application of high throughput hydrogen deuterium exchange mass spectrometry for characterizing protein interactions in complex biological samples
(2023-05-12)
Protein interactions (e.g., protein-protein interactions and protein-ligand interactions) play an important role in regulating the numerous biological processes that dictate cellular activity. The characterization of protein ...
Engineered Bacteriophage Enabled Nanoprobes for SKBR-3 Cancer Cell Specific Imaging and Therapy
(2011)
With the recent progress in nanoscience and great deal of understanding in molecular biology, it is now possible to combine genetic tools with synthetic nano- constructs for improved biotechnology applications. Viruses ...
Electrochemical and enzymatic oxidation of tryptophan and 7-methyluric acid ; and, spectroelectrochemical search for a tertiary alcohol intermediate in the electrochemical oxidation of uric acid /
(1985)
Part III describes the spectroelectrochemical evidence for the tertiary-alcohol intermediate formation during the electrochemical oxidation of uric acid. Electrochemical reduction of the tertiary-alcohol intermediate in ...
Capillary-based analytical technique developments for analysis of bio-sample
(2017-05)
Analytical chemistry plays a significant role in bioscience research. Bio-samples, such as DNA and proteins, are often used for identification purpose or disease related research. Analyzing a biological sample typically ...
The Nature of Water in Bacterial Spores, Sporicidal Activity of Chlorine Dioxide, and Cryoprotectant Properties of Poly(adenylic) Acid
(2013)
Water is the fundamental chemical molecule of life, and the nature of how water interacts with living organisms and how living organisms can maintain liquid water for metabolic function below freezing (cryoprotection) is ...
