Understanding the characteristic changes of retrogradation behavior and edible quality of brown rice modified with inhibiting retrogradation enzymes of .

Brown rice (BR) has gradually become a new choice for consumers due to its exceptionally nutritional value. Whereas starch retrogradation profoundly reduces its edibility, shelf-life and consumer acceptance, limiting the development of BR and even other starch-based food products. So, it is crucial for controlling the retrogradation properties of brown rice starch (BRS), and which has received significant attention in the food industry.

This study focused on GT accumulation in mycelia of mediated by the heme oxygenase-1 (HO-1)/carbon monoxide (CO) signaling.

2D Fe-doped NiO nanosheets with grain boundary defects for the advanced oxygen evolution reaction.

Two-dimensional (2D) nanomaterials with grain boundary defects are attractive to researchers in many fields, such as energy conversion and storage, sensing, catalysis and biological medicine. In this work, a nanostructure of 2D Fe-doped NiO nanosheets (NiFeO) with grain boundary defects was designed and applied in the electrocatalytic oxygen evolution reaction. This nanomaterial was synthesized through a solvothermal strategy followed by a thermally driven conversion process.

An Interfacial Electron Transfer on Tetrahedral NiS /NiSe Heterocages with Dual-Phase Synergy for Efficiently Triggering the Oxygen Evolution Reaction.

Tetrahedral NiS /NiSe heterocages with rich-phase boundaries are synthesized through a simultaneous sulfuration/selenylation process using Ni-based acetate hydroxide prisms as precursor. Such a nanocage-like NiS /NiSe heterostructure can expose more active sites, accelerate the mass transport of the ions/gas, and optimize the interfacial electronic structure, which shows a significantly lower overpotential of 290 mV at 20 mA cm than those of NiS/NiS and NiSe as counterparts. The experimental characterizations and theoretical density functional theory (DFT) calculations unveil that the interfacial electron transfer from NiSe to NiS at the heterointerface can modulate the electronic structure of NiS /NiSe , which further cooperates synergistically to change the Gibbs free energy of oxygen-containing intermediates as the rate-determining step (RDS) from 2.

A quencher-free 2-aminopurine modified hairpin aptasensor for ultrasensitive detection of Ochratoxin A.

A sensitive, efficient and quencher-free fluorescence aptasensor to detect Ochratoxin A (OTA) based on aptamer, 2-aminopurine (2AP) labeled Oligonucleotide sequence, as well as exonuclease I (Exo I) activity was developed. In which the aptamer specific to OTA was modified into a hairpin structure, and 8 bases at the 3' ends are exposed (H); also, 2AP is embedded in the oligonucleotide complementary to the 8 bases (2AP-probe).The detection principle based on 2AP-probe could be bonded to its complementary sequence and quenches the fluorescence of 2AP; The aptamer has a stronger affinity for the target than its complementary sequence; Exo I can dissociate single-stranded DNA and has little effect on double-stranded DNA as well as folded DNA.

Alkaline-Etched NiMgAl Trimetallic Oxide-Supported KMoS-Based Catalysts for Boosting Higher Alcohol Selectivity in CO Hydrogenation.

The acidity/alkalinity and structural properties of NiMgAl trimetallic oxides (MMOs) can be effectively modulated by the alkaline-etching process with various etching times, which are further used as a support to prepare KMoS-based catalysts through the cetyltrimethylammonium bromide-encapsulated Mo-precursor strategy. The enriched surface anion groups in alkaline-etched MMO affect the textural properties, metal-support interaction, and sulfidation degree of the as-synthesized KMoS-based catalysts. As a result, KMoS-based catalysts using alkaline-etched MMO as supports effectively enhance the reducibility and dispersion of Mo species, which exert a positive influence on higher alcohol synthesis (HAS) performance in CO hydrogenation.

Simultaneous Modulation of Composition and Oxygen Vacancies on Hierarchical ZnCo O /Co O /NC-CNT Mesoporous Dodecahedron for Enhanced Oxygen Evolution Reaction.

Electrochemical water splitting is a promising way for the sustainable production of hydrogen, but the efficiency of the overall water-splitting reaction largely depends on the oxygen evolution reaction (OER) because of its sluggish kinetics. Herein, a series of hierarchical ZnCo O /Co O /NC-CNT (NC-CNT=nitrogen-rich carbon nanotube) mesoporous dodecahedrons grafted to carbon nanotubes have been synthesized from ZnCo bimetallic zeolitic imidazolate frameworks (ZnCo-ZIFs) through sequential pyrolysis in nitrogen and mild oxidation in air. The simultaneous modulation of oxygen vacancies, composition, and hierarchical mesoporous architecture remarkably enhanced their electronic conduction and the amount and reactivity of accessible actives; thus boosting their intrinsic activity in the OER.
