Raman fiber lasers and amplifiers will play an increasing role in future optical fiber communication (OFC) systems. Recent progress in the development of special Raman fibers is described. We ...

An electrochem. sensor of acetaminophen (AP) based on electrochem. reduced graphene (ERG) loaded nickel oxides (Ni2O3-NiO) nanoparticles coated onto glassy carbon electrode (ERG/Ni2O3-NiO/GCE) was ...

Graphene-enhanced Raman scattering (GERS) is a recently discovered Raman enhancement phenomenon that uses graphene as the substrate for Raman enhancement and can produce clean and reproducible Raman ...

Raman's rapid measurement frequency of 3 to 5 seconds makes it ideal for process monitoring and control. Solid-state Raman analyzers, such as the MarqMetrix All-In-One Process Raman Analyzer, come ...

where y ^ m e a n is the average polymer concentration of all samples in the cross validation and external test sets.. 3. Results and Discussions. The Raman spectra from the processed samples are ...

However, Raman-activated cell sorting (RACS) of rare target cells from highly heterogeneous systems has remained largely conceptual. Here, we present a positive dielectrophoresis-induced deterministic ...

The first death linked to the Tylenol poisonings was 12-year-old Mary Kellerman, who collapsed at home and was pronounced dead just hours after ingesting a laced capsule, per the Chicago Tribune ...

For years, the assertion that the abortion pill was safer than commonly used drugs was repeated, eventually morphing into the comparison with Tylenol. A Service of EWTN News, Inc.

In 1982, seven people died in Chicago after ingesting cyanide-laced Tylenol James Lewis, who died in 2023, was considered a primary suspect for decades, though he was never charged in connection ...
