FlexMat, EarlyView.Integrating carbonyl lock onto multi‐resonant organoboron emitters is found to go beyond conventional bridge unit. It can not only suppress the molecular relaxation as conventional bridge, but also substantially affect electronic engineering via carbonyl integration, activating multiple up‐conversion channels, thus leading to an accelerated spin‐flip ...

This study investigates the influence of sodium nitrate additives on color changes and myoglobin levels in raw and cooked meat products using CIE Lab color space and UV spectrophotometry. Sausage samples from beef, lamb, and chicken were prepared with varying sodium nitrate concentrations (0 mg/g, 40 mg/g, 80 mg/g, and 120 mg/g), resulting in twelve ...
