Charles Fadley, a physics professor at UC Davis (Davis, California) has been elected as a foreign member of the Royal Society of Sciences at Uppsala, Sweden.
Charles Fadley, a distinguished professor of physics at UC Davis (Davis, California), has been elected into the Royal Society of Sciences at Uppsala. Founded in 1710, this prestigious Swedish institution has counted as members some of the world’s most renowned scientists, including Anders Celsius, Michael Faraday, and Charles Darwin.
Fadley is widely regarded as one of the foremost practitioners of photoelectron spectroscopy, a technique used for studying the composition and electronic state of a material using X-ray beams to excite electrons and a spectrometer to measure their energies. In recent years he has been a leader in the development of methods for studying very thin “nanolayers” of materials buried below surfaces, work that is integral to the development of next-generation computers, memory storage devices and other applications in the emerging field of nanotechnology.
The Uppsala society limits its membership to some 130 Swedish and 100 foreign members, who are elected for life. Fadley’s election brings to 14 the number of U.S.-based scientists in the society.
New SERS-Microfluidic Platform Classifies Leukemia Using Machine Learning
January 14th 2025A combination of surface-enhanced Raman spectroscopy (SERS) and machine learning on microfluidic chips has achieved an impressive 98.6% accuracy in classifying leukemia cell subtypes, offering a fast, highly sensitive tool for clinical diagnosis.
Advancing Soil Carbon Analysis Post-Wildfire with Spectroscopy and Machine Learning
January 14th 2025Researchers from the University of Oviedo used diffuse reflectance spectroscopy (DRS) and machine learning (ML) to analyze post-wildfire soil organic carbon fractions, identifying key spectral regions and algorithms for advancing remote sensing applications.
Oligonucleotide Analysis in Pharmaceutical Quality Control
January 14th 2025Melting point determination using ultraviolet-visible (UV-Vis) spectrophotometry can be used as a sequence-specific method for identifying therapeutic oligonucleotides in pharmaceutical quality control. This method offers a simple, highly selective approach to differentiate between isomers and ensure the integrity of oligonucleotide active pharmaceutical ingredients (APIs) and drug products.
The Optical Properties of Solid Samples
January 14th 2025Transmittance and reflectance measurements, which are useful for estimating the effects of various physical processes, can include thermal treatments, ionizing radiation exposure, optical exposure, and mechanical treatments—on both crystals and thin films.
