Coupling Ferricyanide/Ferrocyanide Redox Mediated Recycling Spent LiFePO with Hydrogen Production.

Replacing the oxygen evolution reaction with thermodynamically more favorable alternative oxidation reactions offers a promising alternative to reduce the energy consumption of hydrogen production. However, questions remain regarding the economic viability of alternative oxidation reactions for industrial-scale hydrogen production. Here, we propose an innovative cost-effective, environment-friendly and energy-efficient strategy for simultaneous recycling of spent LiFePO (LFP) batteries and hydrogen production by coupling the spent LFP-assisted ferricyanide/ferrocyanide ([Fe(CN) ] /[Fe(CN) ] ) redox reaction.

Catalytic ozonation of bisphenol A by Cu/Mn@γ-AlO: Performance evaluation and mechanism insight.

Herein, an alumina-based bimetallic catalyst (CuMn@γ-AlO) was synthesized for bisphenol A (BPA) degradation in the catalytic ozonation process. The catalytic ozonation system could degrade 93.9% of BPA within 30 min under the conditions of pH = 7.

Reactivation of redox active materials boosts the performance of electrochemical desalination with coupling energy storage.

Aqueous redox flow battery (RFB) desalination is considered as an emerging technology for both freshwater production and energy storage. However, the desalination capacity of desalination RFB is constrained by the amount of redox active materials. To break through this innate limit, a tandem redox strategy is reported to boost the desalination capacity of desalination RFB through reactivating the depleted redox active materials to achieve relay desalination.

The different toxicological effects and removal efficiencies of norfloxacin and sulfadiazine in culturing Arthrospira (Spirulina) platensis.

Norfloxacin (NFX) and sulfadiazine (SDZ) are two widely used antibiotics belonging to fluoroquinolone and sulfonamide groups, respectively, and have become the commonly detected micropollutants in aquatic environments. However, only few works have been conducted to investigate the highly probable inhibition of these antibiotic pollutants to Arthrospira platensis, which is an important species of cyanobacteria that is one of primary producers in aquatic ecosystems and should be remarkably sensitive to environmental pollutants due to its prokaryotic characteristics. Hence, the toxicological effects and removal efficiencies of NFX and SDZ in culturing A.

Effect of IoT-based power cycling and quadriceps training on pain and function in patients with knee osteoarthritis: A randomized controlled trial protocol.

Background: Knee osteoarthritis (KOA) is a chronic musculoskeletal disease affecting the entire joint. Exercise therapy is the core treatment plan for non-surgical treatment of KOA, and tele-rehabilitation is also applied to KOA, but there is a lack of research on the comparison of pain and function recovery between different exercise methods combined Internet respectively. The study aims to compare the effects of power cycling and quadriceps training combined with online guidance separately on KOA mitigation of pain, recovery of function, quality of life, and adherence of participants in the community, compared to the control group.

Ecotoxicological effect of enrofloxacin on and the corresponding detoxification mechanism.

Enrofloxacin is a widely used antibiotic targeting DNA gyrase and has become the commonly detected micropollutant in aquatic environments. Thus, the potential toxicity of enrofloxacin to which is a kind of prokaryote similar to Gram-negative bacteria has been hypothesized. However, little is known about the toxicity and degradation mechanism of enrofloxacin during the growth process of .

Bioavailability and toxicity of silver nanoparticles: Determination based on toxicokinetic-toxicodynamic processes.

Determining the bioavailability and toxicity mechanism of silver nanoparticles (AgNPs) is challenging as Ag is continuously released by external or internal AgNP dissolution in the actual exposure system (regardless of the laboratory or the natural environment). Here a novel pulsed-gradient Ag (AgNO) exposure was conducted with zebrafish (Danio rerio) larvae to simulate dissolved gradient concentrations of Ag from polyvinylpyrrolidone (PVP)-coated AgNPs. The accumulation and toxicity of the pulsed-gradient Ag (AgNO) and, in the meantime, the released Ag from PVP-AgNPs were predicted using a toxicokinetic-toxicodynamic (TK-TD) model with obtained Ag parameters.

Rapid and precise compensation of scale factor in a fiber-optic gyroscope with a twin-peaks source.

In this Letter, two gyro outputs containing identical rotation rates are produced by a twin-peaks light source with peak wavelengths of 1530 nm and 1560 nm. We demonstrate that the two outputs' ratio can compensate for the temperature-induced scale factor drift in an interferometric fiber-optic gyroscope (IFOG). When the temperature ranged from -10 to 50°C, the scale factor drift after compensation was about 30 times less than that before compensation, and the minimum drift was ±7.

Open-loop fiber-optic gyroscope with a double sensitivity employing a polarization splitter and Faraday rotator mirror.

In this Letter, a novel open-loop fiber-optic gyroscope configuration with a double sensitivity is proposed. By employing a polarization-maintaining Faraday rotator mirror and a polarization beamsplitter/combiner, light waves propagate twice along the same fiber coil in two orthonormal polarization directions. The reciprocity of the configuration has been verified in theory.

Electrolytic lesions of the medial nucleus accumbens shell selectively decrease ethanol consumption without altering preference in a limited access procedure in C57BL/6J mice.

The central extended amygdala (cExtA) is a limbic region proposed to play a key role in drug and alcohol addiction and to contain the medial nucleus accumbens shell (MNAc shell). The aim of this study was to examine the involvement of the MNAc shell in ethanol and sucrose consumption in a limited and free access procedure in the C57BL/6J (B6) mouse. Separate groups of mice received bilateral electrolytic lesions of the MNAc shell or sham surgery, and following recovery from surgery, were allowed to voluntarily consume ethanol (15% v/v) in a 2 h limited access 2-bottle-choice procedure.

Ethological analysis of scopolamine treatment or pretreatment in morphine dependent rats.

Although scopolamine is currently used to treat morphine addiction in humans, its extensive actions on behaviors have not been systematically analyzed yet, and the underlying mechanisms of its effects still remain ambiguous. The present study was carried out to clarify the possible mechanisms by evaluating the effects of scopolamine pretreatment and treatment on naloxone-precipitated withdrawal signs and some of other general behaviors in morphine dependent rats. Our results showed that scopolamine pretreatment and treatment attenuated naloxone-precipitated withdrawal signs including jumping, writhing posture, weight loss, genital grooming, teeth-chattering, ptosis, diarrhea and irritability, except for wet dog shakes, while general behaviors such as water intake, urine volume and morphine excretion in urine were increased.

Ionotropic glutamatergic neurotransmission in the ventral tegmental area modulates DeltaFosB expression in the nucleus accumbens and abstinence syndrome in morphine withdrawal rats.

The present study sought to assess whether the blockade of ionotropic glutamate receptors in the ventral tegmental area could modulate morphine withdrawal in morphine-dependent rats and the expression of stable DeltaFosB isoforms in the nucleus accumbens during morphine withdrawal. Rats were injected (i.p.
