Fabrication of Polypyrrole–Polystyrene Sulfonate by Amperometric Biosensor‐Based Electropolymerization for Cholesterol Determination in Serum

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Since cholesterol triggers many diseases, many methods have been developed for its determination. In this study, an alternative system for cholesterol determination was developed by preparing amperometric biosensors. In the development of the biosensor, Pt/polypyrrole–polystyrene sulfonate film was prepared by electropolymerization of ...

Insights into the morphology‐productivity relationship of filamentous fungi through small‐scale cultivation and automated microscopy of Thermothelomyces thermophilus

Biotechnology Progress, EarlyView.
Abstract Filamentous fungi are a cornerstone in the biotechnological production of enzymes, proteins, and organic acids. However, challenges in understanding and controlling the relationship between morphology and productivity can limit their application.

The Mastcam‐Z Radiometric Calibration Targets on NASA's Perseverance Rover: Derived Irradiance Time‐Series, Dust Deposition, and Performance Over the First 350 Sols on Mars

Earth and Space Science, Volume 9, Issue 12, December 2022., 2022
Abstract The Mastcam‐Z radiometric calibration targets mounted on the NASA's Perseverance rover proved to be effective in the calibration of Mastcam‐Z images to reflectance (I/F) over the first 350 sols on Mars. Mastcam‐Z imaged the calibration targets regularly to perform reflectance calibration on multispectral image sets of targets on the Martian ...

A Hemispherical Photometric Integrator [PDF]

Journal of the Optical Society of America, 1922
SYNOPSISA study of the errors in spherical photometry due to the presence of the lamps and screens in the Ulbricht sphere led to the development of a fixed convex mirror to be used in place of the two larger screens. A further development of the theory of interference within the instrument led to the adoption of a hemisphere in place of the complete ...

Photometry of Variable Stars, and System Transformability Over Long Time Intervals

Open Astronomy, 2003
The fundamental problem of long-term photometric monitoring of variable stars and of multi-wavelength photometric campaigns is the problem of bringing the data to a common standard.

Cucurbit[7]uril‐Styryl Dye Complexes for Fluorescent Recognition of DNA and Cell Imaging

ChemBioChem, EarlyView.
Recognition properties in solution and in cancer cells: a two dicationic cyanine dyes with different functionalities were developed and studied for their fluorescent properties, cytotoxicity and cellular imaging. The effect of encapsulation was checked using synthetic molecular container of cucurbit[7]uril.
