Summary This study aimed to evaluate the effect of chitosan (CHI) combined electrolytic water (EW) cold sterilisation on muscle quality and myofibril proteins (MP) of large yellow croaker ( Pseudosciaena crocea ) during 12 days of refrigerated storage (4 °C). After the storage period, the sample of the EW + CHI group had the highest rate of hardness (36.68%), springiness (16.11%) among the control group without any treatment (CON), CHI group and EW group and similar tendencies were found in chewiness and cohesiveness. The MP content in the CON group decreased sharply from 80.35 mg g −1 to 57.90 mg g −1 , in contrast to the EW + CHI group, which decreased from 81.65 mg g −1 initially to 80.83 mg g −1 . The conformation of MP α-helix and β-sheet was retained to protect the secondary structure, and the exposure of aromatic amino acid residues was constrained to defend the tertiary structure in EW + CHI treatment which effectively delayed the degradation of MP. Based on these outcomes, EW + CHI treatment could significantly maintain the MP of large yellow croakers and prevent corruption during refrigerated storage.

Effects of slightly acidic electrolyzed water (SAEW) on the storability, quality attributes, and reactive oxygen species (ROS) metabolism of litchis were investigated. Results showed that SAEW-treated litchis presented better quality attributes and storability than control litchis. On storage day 5, the commercially acceptable fruit rate of control litchis was 42%, while SAEW-treated litchis displayed 59% higher rate of commercially acceptable fruit, 21% lower pericarp browning index, and 13% lower weight loss percentage than control litchis. Additionally, compared to control litchis, SAEW-treated litchis demonstrated higher activities of SOD, CAT and APX, higher levels of GSH, AsA, DPPH radical scavenging ability, and reducing power, but lower O 2 −· generation rate, lower levels of H 2 O 2 and MDA. These findings indicated that SAEW treatment could elevate antioxidant capacity and ROS scavenging ability, reduce ROS production and accumulation, and lower membrane lipid peroxidation, thereby retaining the quality attributes and storability of litchis.

Electrodes are key components in water splitting. Owing to their porous structures , commercial foam metal electrode matrices can provide numerous active sites. However, the complex and disordered surface structure impedes the release of the generated gas bubbles, and sluggish mass transfer usually becomes a bottleneck in the electrochemical reaction kinetics. For this purpose, this study proposes a pulse-jet electrodeposition method for the preparation of nickel-based dendritic electrode matrices (NDEM). This research shows that the electrode matrix prepared under the conditions of V = 26 V, PW = 10 μs, and PI = 35 μs has a unique surface structure, which can quickly release bubbles, effectively attract ions, and accelerate mass transfer on the electrode surface , resulting in excellent electrochemical performance . After loading the catalyst, the NDEM requires only 1.552 V to reach a current density of 10 mA cm −2 . At an electrolysis voltage of 2.5 V, the hydrogen production was 45% higher than that of the NF electrode, and it had excellent stability. This study opens a new avenue for the design of highly efficient and low-cost electrodes for water splitting.

Electrochemical water splitting for hydrogen production is of great significance in exploring sustainable energy for the upcoming low-carbon era, the discovery of electrocatalysts with high activity and inexpensive is highly important to expedite the extremely sluggish kinetics of oxygen evolution reaction (OER). Herein, an efficient OER electrocatalyst was designed by doping trace Fe into Ni 2 P via a simple structural transformation. The crystal structure and surface chemical state analysis demonstrated the introduction of Fe dopant and the successful formation of the host Ni 2 P. As-prepared Fe-Ni 2 P microspheres greatly optimized the intrinsic activity of the active site and accelerated the mass transfer rate. Intriguingly, the electrochemical tests certified that trace Fe doping can increase the activity of nickel phosphide more significantly. High valence state transition from Ni P bond to Ni O bond was clearly observed, suggesting the new active species can be easily formed during OER. This article provides a trace Fe doping strategy for the study of efficient electrocatalysts to improve the kinetics of OER.

The fabrication of advanced electrocatalysts for urea-assisted electrolytic water splitting is of great significance for yielding green hydrogen. In this study, Ce doping a quaternary sea urchin like medium-entropy NiCoFe layered double hydroxide (Ce 1.2 -NiCoFe-LDH) nanoshe et s were obtained by employing a doping engineering strategy. Characterization experimental results confirmed that Ce dopants could modify the oxygen vacancy structure of NiCoFe-LDH, accelerating charge and mass transfer. thereby enhancing the urea decomposition. The electrochemical results indicated that Ce 1.2 -NiCoFe-LDH demonstrated high-efficiency catalysis for UOR, characterized by high intrinsic activity, rapid kinetics, and robust durability. The overpotential of Ce 1.2 -NiCoFe-LDH was only 48 mV at the current density of 10 mA cm −2 , much lower than the commercial IrO 2 (126 mV at 10 mA cm −2 ). The tafel slope of Ce 1.2 -NiCoFe-LDH (62 mV dec −1 ) was also better than those of IrO 2 (88 mV dec −1 ) and NiCoFe-LDH (99 mV dec −1 ). Compared with the commercial IrO 2 , the Ce 1.2 -NiCoFe-LDH exhibited a change of only 3.2 % after a 12-hour chronoamperometric test, indicating an improvement in stability. Impedance comparison between the two hydrotalcites revealed that Ce 1.2 -NiCoFe-LDH possessed lower impedance, potentially enhancing catalytic efficiency. Therefore, this work illustrates that the modulation of oxygen vacancies in electrocatalysts, induced by the heteroatom doping effect, can enhance the electrocatalytic oxidation performance of small molecules for hydrogen production.

High surface states induced photoelectrochemical (PEC) activity and stability issue is the major performance bottleneck for nanostructured WO 3 photoanode. Here we report that amorphous TiO 2 ( α -TiO 2 ) be used as passivator to modify the surface states of WO 3 nanoflakes film for improving its PEC water oxidation performance. In comparison with bare WO 3 film, the α -TiO 2 -coupled WO 3 ( α -TiO 2 /WO 3 ) film is of higher PEC water oxidation activity and stability. The photocurrent on α -TiO 2 /WO 3 film photoanode is improved by 2 times that reached 1.4 mA/cm 2 in 0.1 M Na 2 SO 4 solution at 0.8 V ( vs. SCE). After α -TiO 2 coupling, the UV–vis absorption edge and intensity of WO 3 film do not change obviously, but the formation and oxidation kinetics of H 2 O 2 on WO 3 photoanode are modified. The density functional theory calculations indicate the monoclinic WO 3 (002) has a surface energy of 1.17 J/m 2 , whereas the α -TiO 2 /WO 3 (002) with a much lower surface energy of 0.3 J/m 2 . Additionally, the length of Ti O bond of α -TiO 2 is changed from the initial 1.929 Å to a shorter length of 1.886 Å and a longer length of 2.290 Å in α -TiO 2 /WO 3 (002) through the O 2- -W 6+ bonding effect at α -TiO 2 /WO 3 interface. Therefore, the enhanced PEC water oxidation performance on α -TiO 2 /WO 3 film can be attributed to that α -TiO 2 passivates the surface states of WO 3 nanoflakes film, and the formation of H 2 O 2 from the photoexcited-electrons/dissolved-oxygen route is depressed and the PEC oxidation of H 2 O 2 is accelerated.

A honeycomb-like porous self-supporting Ni-Al(G) electrode was successfully prepared by low-pressure cold spraying combined with heat treatment. The main components of the electrode were Ni and NiAl. Graphene was uniformly dispersed throughout the electrode, exhibiting a 3-D distribution, which increased the active site of electrode and improved the electron exchange rate. The electrochemical properties of the Ni-Al(G) electrode were characterized using 6 M KOH. As a result, the Ni-Al(G) electrode requires only an overpotential of 130 mV to achieve a current density of 100 mA cm −2 , and a Tafel slope of 35.5 mV dec −1 . In addition, the electrode exhibited excellent stability. The addition of graphene and the honeycomb-like porous structure of the Ni-Al(G) electrode resulted in an excellent hydrogen evolution activity. This study provides a simple and rapid technique for building high-performance, low-cost, and industrially available electrodes for the efficient alkaline HER.

Trace precious metal modifying inexpensive transition metal catalyst is an effective method to optimize the activity, stability and cost of hydrogen evolution catalysts. In this feature work, self-supporting sandwich structured Co–Pt–Co/CC sheets were assembled on a carbon cloth (CC) by a simple electrodeposition/chemical displacement alternate growth method. Surprisingly, only 2.1 wt % Pt sandwich layer greatly improved the electrochemical activity of Co–Pt–Co/CC, which delivered a current density of 10 mA cm −2 at an overpotential as low as 46 mV. Importantly, its overpotential is almost 6 times lower than that of Co/CC, and is comparable to that of Pt–Co/CC. After well-tuning the sandwich layer, the optimized Co–Pt–Co/CC exhibited a higher current density and better long-term durability compared with Pt–Co/CC and Co/CC, which can be attributed to the unique tissue-structure and electronic structure optimization of the Co–Pt–Co/CC by the Pt sandwich layer.

This study developed a ternary NiCoCe/NF nanosheet composite material aimed at enhancing the efficiency of the oxygen evolution reaction (OER) in alkaline water. Cerium oxide, due to its high catalytic activity, large specific surface area, and good electronic conductivity, serves as an ideal electrocatalyst, effectively promoting the oxidation of water molecules. Research indicates that the appropriate doping of cerium oxide can create a synergistic effect with NiCo, significantly improving the OER activity of the composite catalyst. In a 1 M KOH solution, the ternary composite exhibited a low initial potential of 1.44 V (vs. RHE) and a mere overpotential of 207 mV at 10 mA cm −2 . The structural stability of cerium oxide prevents the degradation of the catalyst under high current densities, allowing the composite catalyst to maintain long-term catalytic activity during the OER process and extend its operational lifespan. Consequently, the NiCoCe/NF catalyst demonstrates excellent stability, with no performance decay observed after 36 hours of continuous water electrolysis at 100 mA cm −2 . This study presents a novel approach to designing efficient and stable catalysts for water decomposition.

Three protein-rich materials were pretreated with a self-designed alkaline electrolyzed water (AEW) pretreatment equipment to promote the release of angiotensin I-converting enzyme (ACE) inhibitory peptides by improving hydrolysis efficiency. According to degree of hydrolysis (DH) and ACE inhibitory activity, defatted walnut meal (DWM) was selected to study antihypertensive activity by hydrolysis in assistance of AEW pretreatment. It was found DWM pretreated with AEW at pH 11.5 followed by Alcalase hydrolysis exhibited the highest DH (21.96%), protein recovery rate (94.76%), and ACE inhibitory activity (IC 50 of 0.137 mg/mL), in which AEW pretreatment resulted in the transformation of α-helix and β-turn to random coil and the destruction of hydrogen bonds to expose more cleavage sites to enhance hydrolysis efficiency. Thereafter, ACE inhibitory peptides GIENYRVV (IC 50 of 0.102 mg/mL) and AGRISTVNSHTLPVL (IC 50 of 0.20 mg/mL) were identified from the hydrolysate. Overall, AEW pretreatment was an innovative strategy to promote the release of antihypertensive peptides during hydrolysis.

The labeled quantitative proteomic method was used to study the changes in muscle proteins of large yellow croaker ( Pseudosciaena crocea ) treated with electrolytic water (EW) and chitosan (CHI) combined preservation during 12 days of refrigeration storage (4 °C). The analysis indicated that the freshness instructed by total viable count (TVC), total volatile basic nitrogen (TVB-N) and K value was significantly maintained after combined preservation during storage at 4 °C for 12 days (CS12). Furthermore, 46 differentially abundant proteins (DAPs) were detected in storage at 4 °C for 12 days (S12) compared to the freshness group (F), which bioinformatics confirmed were mainly skeletal proteins and enzymes. Correlation analysis showed that 19 highly correlated DAPs could be used as potential protein markers of freshness. Changes in the relation of freshness and protein were shown in further correlative analysis of F and CS12, which were caused by combined preservation. Therefore, combined preservation is promising in the quality and stability of large yellow croakers.

Incorporating metal-organic frameworks (MOFs) especially the ones with protic functional groups into proton exchange membrane (PEM) can effectively improve its proton conductivity . Lanthanide MOFs (Ln-MOFs) have been recognized as more potential candidates exhibiting proton dissociation capability. However, the performance of PEM upon integrating Ln-MOFs in water electrolyzer has yet to be investigated. In this study, Nafion composites with different loadings of lanthanide Ce-UiO-66 were prepared, characterized and tested by comparing with the non-lanthanide Zr-UiO-66. It was revealed that the proton conductivity of Ce-UiO-66/Nafion composite membrane was higher than pristine Nafion and Zr-UiO-66/Nafion membrane, which was attributed to the fact that the Ce-UiO-66 doping contributed to the construction of the hydrogen-bonded network to enhance the proton conductivity. At 3 wt% Ce-UiO-66 doping, the proton conductivity of the composite membrane can reach 124.45 mS/cm, which is significantly improved by 17 % compared with Zr-UiO-66/Nafion. Such a trend is mainly contributed by the lower proton affinity and proton transfer capability of Ce atoms in Ce-UiO-66, and the higher number of water molecules around Ce atoms favors the reduced tortuosity of the proton conduction pathway in membranes. Single electrolytic cell tests demonstrated the enhancement of electrolysis efficiency upon Ce-UiO-66 doping was improved from 58.77 % to 65.37 % at a current density of 2 A cm −2 .
