Abstract: In this paper, equivalent electric circuit models of a commercial 1.2-kW proton exchange membrane (PEM) fuel cell stack are proposed based on AC impedance studies. The PEM fuel cell stack ...
When light reflects off a surface, not all of it reflects off at the same wavelength; some photons impart a portion of their ...
Neutron sources can be directly identified from measured spectra rather than proxies using inference tools adapted from ...
Researchers from Skoltech have devised a way to detect infrared radiation across a wide range without cooling the detector.
Fraunhofer ILT in Aachen has developed a highly complex laser-optical system for a quantum computer currently under construction at the 5th Institute of Physics at the University of Stuttgart. This ...
Unlike almost every other kind of microscope, atomic-force microscopes (AFMs) don’t use any kind of optical beam to image ...
As instruments grow faster, leaders say clinical impact will depend on trust, standards, data, and assays built for real ...
Sheher Mohsin explains how CCS measurements add a physical confirmation layer beyond mass and retention time in PFAS analysis. Why are ion mobility and CCS measurements becoming increasingly important ...
Estimation of surface area and pore volume of activated carbons by methylene blue and iodine numbers
Data of methylene blue number and iodine number of activated carbons samples were calibrated against the respective surface area, micropore volume and total pore volume using multiple regression. The ...
