Whey protein-epigallocatechin gallate (WP-EGCG) covalent conjugates and non-covalent nanocomplexes were prepared compared using Fourier-transform infrared spectra. The effect of pH (at 2.6, 6.2, 7.1, 8.2) on the nanocomplexes' functional properties WP-EGCG interactions investigated by studying antioxidant activity, emulsification, fluorescence quenching, molecular docking, respectively.With formation complexes, amide band decreased; -OH peak disappeared; activity complexes was 2.59-...
Understanding the spatial distribution of P1 centers is crucial for diamond-based sensors and quantum devices. serve as polarization sources dynamic nuclear (DNP) sensing play a significant role in relaxation nitrogen vacancy (NV) centers. Additionally, NV correlates with centers, are formed through conversion We utilized DNP pulsed electron paramagnetic resonance (EPR) techniques that revealed strong clustering population exhibit exchange coupling produce asymmetric line shapes. The 13C...
To extract anthocyanins with high efficiency, a hypothesis for high-speed shear homogenization extraction (HSHE) method was established through combination of solvent and ultrasonic-assisted extractions. The efficacy this demonstrated by performing qualitative quantitative analyses 16 extracted from five northern vegetables, berry fruits using ultra-high-performance Q-Exactive Orbitrap tandem mass spectrometry. Single-factor experiments were conducted varying ethanol concentration,...
The nitrogen-vacancy (NV) center in diamond has enabled studies of nanoscale nuclear magnetic resonance (NMR) and electron paramagnetic with high sensitivity small sample volumes. Most NV-detected NMR (NV-NMR) experiments are performed at low fields. While fields useful many applications, high-field NV-NMR fine spectral resolution, signal sensitivity, the capability to observe a wider range nuclei is advantageous for surface detection, microfluidic, condensed matter aimed probing micro-...
An interacting spin system is a great testbed for fundamental quantum physics and applications in sensing simulation. For these investigations, detailed information of the interactions, e.g. number spins their interaction strengths, often required. In this study, we present identification characterization single nitrogen-vacancy (NV) center coupled to two electron spins. experiment, first identify well isolated NV center, characterize its decoherence time. Then perform NV-detected...

To extract anthocyanins with high efficiency, a high-speed shear homogenization extraction (HSHE) method was established through combination of solvent and ultrasonic-assisted extractions. Sixteen were qualitative quantitative from five northern vegetables, berry fruits by UHPLC-Q-Exactive Orbitrap MS/MS. Optimal conditions (ethanol 70–80%, 40–50°C, pH 3–4, performed twice) determined using HSHE (5 min, 10,000 r/min, 25°C) assisted shaker (60 min) ultrasonography (1600 W, 30 procedure. The...
Aiming to improve EGCG’s inhibition on α-glucosidase, Mn (II)-EGCG complex was prepared and characterized by Fourier transform infrared (FT-IR), mass spectrometry (MS), nuclear magnetic resonance hydrogen (1H-NMR), thermogravimetric analysis (TGA). The interactions between Mn-EGCG α-glucosidase were revealed using fluorescence spectra, circular dichroism (CD) molecular docking. FT-IR of showed that -OH participated in the coordination with MS found a peak m/z 565.4, presumed be C22H14O11Mn2...
