Elevated levels of branched chain fatty acids in low-salt fish sauce by co-fermentation: flavor improvement and metabolism analysis.

Background: Traditional fish sauce products rely on relatively long fermentation time and high salt concentration, resulting in inconsistent quality and health risks. Branched-chain fatty acids (BCFAs) are associated with nutritional benefits and health-care effects, mainly derived from food fermentation. This study aimed to screen BCFAs-producing bacteria with high protease and aminotransferase activity as starter cultures for fish sauce fermentation.

Integrative virtual nursing simulation in teaching cardiopulmonary resuscitation: A blended learning approach.

Methods: First year nursing students from a medical college participated as volunteers in this study.

Achieving visible and near-infrared dual-emitting mechanoluminescence in Mn single-doped magnesium aluminate spinel.

Visible (VIS) and near-infrared (NIR) mechanoluminescence (ML) materials have been developed rapidly for use in energy conversion, biological applications and mechanical sensing. The realization of visible and NIR ML in single host materials meets the dual requirements of visualization and anti-interference for high-precision mechanical sensing. In this work, Mn single-doped magnesium aluminate spinel MgAlO with excellent ML performance was studied in detail.

Design and tuning Cr-doped near-infrared phosphors for multifunctional applications crystal field engineering.

Nowadays, near-infrared (NIR)-emitting luminescence materials with broad application prospects have drawn great attention. SrGaO:Cr is a new type of solid light source material that emits NIR light with wide application prospects. However, the narrow full width at half maximum (FWHM) restricts its further multifunctional applications.

Ultra-bright green-emitting phosphors with an internal quantum efficiency of over 90% for high-quality WLEDs.

There is an urgent need to develop phosphors with high quantum efficiencies (QEs) since white light-emitting diodes (WLEDs) have emerged as a new generation of illumination materials. Utilizing energy transfer to improve the absorption of activators and adjust the emission colors of samples is one effective strategy. Here, color-tunable phosphors of the form CaAlO:Ce,Tb were synthesized aiming at efficient energy transfer from Ce to Tb.

Insight into the crystal structure and photoluminescence properties of an extremely broadband yellow-emitting phosphor SrMgCe(PO):Eu.

The combination of binary complementary color phosphors with near-ultraviolet (NUV) light-emitting diode (LED) chips was put forward to lower the energy loss caused by the reabsorption of the combination of tricolor phosphors with NUV LED chips. Thus investigating broadband yellow-emitting phosphors with enriched red components in the spectral range has gained much attention. Here, an extremely broadband yellow-emitting phosphor SrMgCe(PO):Eu with sufficient red component in the spectral region was synthesized.

Investigation of the Microstructures of Graphene Quantum Dots (GQDs) by Surface-Enhanced Raman Spectroscopy.

Photoluminescence (PL) is the most significant feature of graphene quantum dots (GQDs). However, the PL mechanism in GQDs has been debated due to the fact that the microstructures, such as edge and in-plane defects that are critical for PL emission, have not been convincingly identified due to the lack of effective detection methods. Conventional measures such as high-resolution transmission electron microscopy and infrared spectroscopy only show some localized lattice fringes of GQDs and the structures of some substituents, which have little significance in terms of thoroughly understanding the PL effect.
