Establishment of DAS-ELISA and lateral flow immunochromatography for the detection of peanut allergen Ara h 3 after heat-moisture treatment.

Peanuts are highly nutritious but pose a significant risk of triggering food allergies. While heat treatment can reduce the allergenicity of many foods, it may also alter their structure, potentially impacting detection results. This study employed double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) and lateral flow immunochromatography (LFIA) to evaluate the allergen Ara h 3 following heat-moisture treatment.

A ferroelectrically modulated ultrasensitive two-dimensional perovskite phototransistor with zero-gate-bias.

Two-dimensional (2D) organic-inorganic halide perovskites are promising sensitive materials for optoelectronic applications due to their strong light-matter interactions, layered structure, long carrier lifetime and diffusion length. However, a high gate bias is indispensable for perovskite-based phototransistors to optimize detection performances, since ion migration seriously screens the gate electric field and the deposition process introduces intrinsic defects, which induces severe leakages and large power dissipation. In this work, an ultrasensitive phototransistor based on the (PEA)SnI perovskite and the Al:HfO ferroelectric layer is meticulously studied, working without an external gate voltage.

The third strategy: modulating emission colors of organic light-emitting diodes with UV light during the device fabrication process.

The modulation of emission color is one of the most critical topics in the research field of organic light-emitting diodes (OLEDs). Currently, only two ways are commonly used to tune the emission colors of OLEDs: one is to painstakingly synthesize different emitters with diverse molecular structures, the other is to precisely control the degree of aggregation or doping concentration of one emitter. To develop a simpler and less costly method, herein we demonstrate a new strategy in which the emission colors of OLEDs can be continuously changed with UV light during the device fabrication process.

Polyphenols have good antioxidant and nitrite-scavenging effects.

Partial Ligand Stripping from CsPbBr Nanocrystals Improves Their Performance in Light-Emitting Diodes.

Halide perovskite nanocrystals (NCs), specifically CsPbBr, have attracted considerable interest due to their remarkable optical properties for optoelectronic devices. To achieve high-efficiency light-emitting diodes (LEDs) based on CsPbBr nanocrystals (NCs), it is crucial to optimize both their photoluminescence quantum yield (PLQY) and carrier transport properties when they are deposited to form films on substrates. While the exchange of native ligands with didodecyl dimethylammonium bromide (DDAB) ligand pairs has been successful in boosting their PLQY, dense DDAB coverage on the surface of NCs should impede carrier transport and limit device efficiency.

Stepwise-Process-Controlled Ligand Management Strategy for Efficient and Stable Perovskite Quantum Dot Solar Cells.

CsPbI perovskite quantum dots (QDs) have attracted much attention in the field of solar cells because of their excellent photovoltaic properties. Conventional modification of long-chain insulating ligands can ensure good dispersion and film-forming stability of QDs, but the limitations of their low defect passivation ability and poor charge transport ability will make them fail to achieve high efficiency in the corresponding solar cell devices. In this study, by introducing "Benzylphosphonic acid" short-chain ligands to the surface of CsPbI QDs, the ligands were re-administered on the surface during the preparation of the CsPbI QDs as well as during the film-forming process.

Effects of the addition of leucine on flavor and quality of sausage fermented by YZU-06 and CGMCC 3475.

Methyl-branched aldehydes, especially 3-methylbutanal, have been reported to be perceived either as a malty or as a nutty/chocolate-like aroma and were considered an important flavor contributor in fermented meat products. Decomposition of leucine (Leu) by branched-chain amino acid transaminase (BACT) is a crucial step in the metabolism of Leu to 3-methylbutanal. This study was conducted to explore the effects of mixed-starter culture ( YZU-06 and CGMCC 3475) and addition of Leu (0, 1, and 3 mM) on the flavor and quality of fermented sausages.
