An Explicit Estimated Baseline Model for Robust Estimation of Fluorophores Using Multiple-Wavelength Excitation Fluorescence Spectroscopy

Research Background Fluorescence spectroscopy is a widely used method for identifying and quantifying fluorescent substances (fluorophores). However, quantifying the fluorophores of interest becomes challenging when the material contains other fluorophores (baseline fluorophores), especially when the emission spectrum of the baseline is not well-de...

Evidence for Electron–Hole Crystals in a Mott Insulator

Background In recent years, researchers have shown significant interest in electron-hole crystals within Mott insulators. These types of crystals can achieve quantum excited states, have the potential to support counterflow superfluidity and topological order, and possess long-range quantum entanglement characteristics. However, experimental eviden...

Enabling Three-Dimensional Real-Time Analysis of Ionic Colloidal Crystallization

Enabling Three-Dimensional Real-Time Analysis of Ionic Colloidal Crystallization

Real-Time 3D Analysis of Ionic Colloidal Crystallization Background and Motivation In the study of molecular crystals, the structure is typically identified through scattering techniques, as we cannot directly observe the internal structure. Due to their larger volume, micrometer-sized colloidal particles allow us to observe their crystallization p...

Neuritogenic Glycosaminoglycan Hydrogels Promote Functional Recovery After Severe Traumatic Brain Injury

Neuritogenic Glycosaminoglycan Hydrogels Promote Functional Recovery After Severe Traumatic Brain Injury Traumatic brain injury (TBI) is a serious neurological disorder, and the complexity of its treatment has long plagued the medical community.
