Solvent extraction has emerged as an extremely effective and highly promising approach for extracting lithium ions from salt lake brine, primarily due to its remarkable Li + selectivity, cost-effectiveness, and high efficiency. In this paper, the utilization of bis-(2,4,4-trimethylpentyl)-phosphinic acid (Cyanex 272) as an iron-fixed reagent in an organic solution, along with tributyl phosphate (TBP) as the extractant and FeCl 3 as the co-extractant, is proposed. Compared to the traditional TBP-FeCl 3 system, TBP-Cyanex 272 extraction system holds potential advantages in terms of a more environmentally friendly extraction process. Particularly, during the stripping process, the coordination of Fe 3+ with Cyanex 272 and TBP at a lower Cl − concentration allows Fe 3+ to be retained in the organic phase, thereby facilitating a greener extraction process. This method has effectively overcome the technical challenges associated with TBP-FeCl 3 systems, such as strong acid stripping and strong base saponification. Additionally, as an environmentally friendly extraction system, TBP-Cyanex 272 demonstrates exceptional performance in terms of lithium extraction efficiency and phase separation.

Generally, polymeric materials with superior damping characteristics are in great demand for many advanced functional applications, such as in building, aerospace, electronics, and transport sectors. However, it still remains a challenge to improve the damping characteristics of such materials owing to the lack of adequate practical knowledge in this area. Here, we report on the successful fabrication of silicon rubber (SR)/ferric oxide (Fe 3 O 4 ) composites with excellent damping characteristics. The results obtained from the study showed that the damping characteristics of the specimens increased with the loading of Fe 3 O 4 within a range of −105°C to 200°C. Specifically, the damping factor (tan δ ) is 0.45 at room temperature, and the effective working temperature, the temperatures that correspond to the tan δ > 0.3, ranged from −105°C to 165°C for the loading of Fe 3 O 4 at 60 phr. The scanning electron microscopy results showed that the excellent damping characteristics of composites can be attributed to the good dispersion of Fe 3 O 4 in the SR matrix. This work, therefore, opens up a pathway toward a relatively easy and up-scalable means for fabricating polymer composites that have superior damping characteristics and ones with a wider applicability.

The hypoxia microenvironment post myocardial infarction (MI) critically disturbs cellular metabolism and inflammation response, leading to scarce bioenergy supplying, prolonged inflammatory phase and high risk of cardiac fibrosis during cardiac restoration. Herein, an injectable hydrogel is prepared by Schiff-base reaction between fructose-1,6-bisphosphate (FBP)-grafted carboxymethyl chitosan (CF) and oxidized dextran (OD), following by loading fucoidan-coated baicalin (BA)-encapsulated zein nanoparticles (BFZ NPs), in which immunoregulatory and metabolism improving functions are integrally included. The grafted FBP serves to enhance glycolysis and provide more bioenergy for cardiomyocytes survival under hypoxia microenvironment, and elevating cellular antioxidant capacity via pentose phosphate pathway. OD with intrinsic anti-inflammatory effect can induce M2 polarization of macrophages to accelerate inflammatory elimination. While facing the possibility of endothelial-to-mesenchymal transition (EndoMT) caused by excessive expressed TGF-β1 secreted from M2 macrophages, BFZ NPs can target endothelia cells and intracellularly release BA to regulate the level of fatty acid oxidation, resulting in retained endothelial features and decreased risk of cardiac fibrosis. After being injecting the hydrogel into rats’ infarcted cardiac, the 28 day-post surgical outcomes demonstrate its benign effects on restoring cardiac functions and attenuating adverse left ventricular remodeling. This study shows a promising measure for MI treatment with immunoregulating and metabolism regulation comprehensively.

As a new type of wound dressing, hydrogels have attracted more and more attention. However, traditional hydrogel wound dressings lack inherent antibacterial properties and are difficult to match irregular wounds, which leads to an easy wound bacterial infection. To solve the problems associated with traditional hydrogels, in this research, a thermosensitive hydrogel (PFLD) for wound dressings was developed based on Poloxamer 407 (PF127), lysine (Lys), and 3,4-dihydroxyphenylacetic acid (DOPAC). Rheological tests indicated that the PFLD hydrogel possesses injectability, adaptability to deformation, and sufficient mechanical strength for wound dressing applications. In addition, it could in situ gel at 33 °C, which indicated that the hydrogel could undergo sol-to-gel transition under body temperature. Upon using it in wound treatment, it could adapt to irregular wounds to achieve full coverage of the wound and promote the rapid hemostasis of wound bleeding. Due to the presence of DOPAC in the hydrogel, it exhibited excellent antibacterial and antioxidant properties on the wounds. The skin defect model showed that the wound shrinkage was the fastest after PFLD hydrogel treatment. On day 14, the wound shrinkage rates were 81.68 and 99.77% for the control and PFLD hydrogel groups, respectively. Therefore, the PFLD hydrogel has a broad application prospect as a dressing for the treatment of irregular wounds.

A novel droplet separation method was proposed by using an array protrusion microchannel, which could divert droplets of different sizes into designated branch channels. The performance and mechanism of droplet sieving were investigated. In this work, three distinct flow patterns were obtained: partial sieving, complete sieving, and main drop loss regimes. The influences of droplet length and operation conditions on the sieving efficiency were studied systematically. It was found that, in the partial sieving flow pattern, the increase of small droplet diameter is not conducive to sieving, and there exists a critical diameter of the small droplet for complete sieving under a constant main droplet size, which relies primarily on the array protrusion height. The operating range of the complete sieving flow pattern extends when increasing the main droplet size, and the critical capillary number for evolving into the main droplet loss flow pattern rises. The sieving efficiency increases with the flow rate of the continuous phase in the regulating channel while decreasing with that in the main channel.

Bacterial infection is the most common risk factor that causes the failure of implantation surgery. Therefore, the development of biocompatible implants with excellent antibacterial properties is of utmost importance. In this study, NIR light-driven AgBiS2@ZIF-8 hybrid photocatalysts for rapid bacteria-killing were prepared. AgBiS2@ZIF-8 exhibited excellent photocatalytic activity due to the rapid transfer of photoelectrons from AgBiS2 to ZIF-8, resulting in abundant reactive oxygen species (ROS) to kill bacteria. Meanwhile, AgBiS2@ZIF-8 exhibited a noteworthy photothermal effect, which could effectively convert NIR light into heat. Subsequently, the NIR light-driven antibacterial activity of AgBiS2@ZIF-8/Ti against S. aureus and E. coli was studied. The experimental results showed that AgBiS2@ZIF-8 displayed enhanced photodynamic therapy (PDT) and photothermal therapy (PTT) performance. Under irradiation with 808 nm NIR light for 10 min, AgBiS2@ZIF-8/Ti could effectively eliminate 98.55% of S. aureus in vitro, 99.34% of E. coli in vitro and 95% S. aureus in vivo. At the same time, AgBiS2@ZIF-8/Ti had good biocompatibility. Therefore, AgBiS2@ZIF-8/Ti showed potential as an antibacterial material, which provided a strategy to fight polymicrobial infections.

An ultra-sensitive phase plasmonic sensor combined with weak value amplification is proposed for the detection of IgG, as a model analyte. Phase detection is accomplished by self-interference between the p-polarization and the s-polarization of the light. With the principles of weak value amplification, a phase compensator is used to modulate the coupling strength and enhance the refractive index sensitivity of the system. On a simple Au-coated prism-coupled surface plasmon resonance (SPR) structure, the scheme, called WMSPR, achieves a refractive index sensitivity of 4.737 × 104 nm/RIU, which is about three times higher than that of the conventional phase-based approach. The proposed WMSPR biosensor gives great characteristics with a high resolution of 6.333 × 10−8 RIU and a low limit of detection (LOD) of 5.3 ng/mL. The results yield a great scope to promote the optimization of other SPR biosensors for high sensitivity.

The scourge of drug addiction and abuse poses a significant challenge to society. Opioid drugs acting on μ-opioid receptor (OPRM1) make it one of the pivotal targets for drug addiction. In the past decade, sewage analysis has become a prevalent method of drug monitoring. However, traditional methods of detecting drugs in sewage are cumbersome, and rapid detection methods are relatively lacking. To address this, an innovative OPRM1-SNAP-tag/CMC method to directly identify drug components in sewage was established. Cell membrane chromatography (CMC) is an affinity chromatography technique which effectively detects receptor affinity substances. Cells constructed with high expression of specific receptor could be used to screen for compounds acting on the receptor. CMC based on OPRM1 provides a potentially convenient and effective tool for the detection of targeted drug components in sewage. In this study, the selectivity, reproducibility, column lifetime, and carryover of the CMC column had been assessed. Initially, we eluted the collected domestic sewage with methanol and acetonitrile, and the retention peaks were observed on the CMC system. Subsequently, without any preliminary sample preparation, we directly injected filtered samples of suspicious sewage into the OPRM1-SNAP-tag/CMC system, where we observed retention peaks as well. The retained components were further identified as morphine by using UPLC-MS/MS. In conclusion, the OPRM1-SNAP-tag/CMC method stands out as a reliable and robust model for the detection of drug components in sewage. It provides a valuable analytical tool for frontline drug control efforts, enhancing our capacity to monitor and mitigate the impact of drug abuse on society. Graphical Abstract

The electrophysiological interface is essential for understanding electrical activities within biological organisms and human-machine interaction. However, traditional preformed bioelectrodes show insufficient interface contact with hairy and irregular skin, causing signal attenuation and distortion. Here, an on-skin-formed silk protein bioelectrode is reported with a conformable and robust interface, achieving a high signal-to-noise ratio for electromyographic signals, showing up to a 38.9% increase compared to traditional ones. The fluid-gel transition of silk protein is induced by a gelling agent composed of ethanol and sodium alginate, leading to a conformable and seamless interface with hairy and irregular human skin, thus resulting in a high signal-to-noise ratio. The developed bioelectrode can record electrophysiological signals stably, even underwater. Additionally, human-machine interaction using electromyographic signals is designed to precisely control the model car's motion trajectory. This work presents an effective method for developing a seamless and conformable electrophysiological interface in bioelectronics.

It is a challenge to effectively degrade phenanthrene (PHE) pollutants, which are widely present in aquatic environments, in order to reduce harm to humans and ecosystems. In this study, an S-scheme TiO 2 /g-C 3 N 4 photocatalytic system is constructed using 0D TiO 2 nanospheres and 2D g-C 3 N 4 nanosheets for the removal of PHE from water under sunlight irradiation. The effects of irradiation time, quality ratio of TiO 2 to g-C 3 N 4 , and cycle time on the performance of the TiO 2 /CN photocatalyst are investigated. The experimental results show that the ratio of TiO 2 to g-C 3 N 4 significantly affects the photocatalytic activity of the photocatalyst. Under the optimal ratio of TiO 2 to g-C 3 N 4 (50 % TiO 2 /CN), the apparent reaction rate constant for phenanthrene reached 0.00796 min −1 , which is 11.5 times higher than that of pure TiO 2 (0.00069 min −1 ). The tests of optical performance and photoelectrochemical properties further confirmed that the construction of the TiO 2 /g-C 3 N 4 S-type photocatalyst successfully enhanced the spatial separation efficiency of photogenerated carriers and ensured a continuous supply of energy during the redox reaction process. Converting highly toxic phenanthrene into a non-toxic green degradation product provides an practical strategy for the safe treatment of PHE in aqueous environments through the use of visible-light-driven heterojunction photocatalysts. Additionally, the data collected on phenanthrene degradation in this study will provide valuable references for developing degradation methods for other PAHs, such as naphthalene, anthracene, and pyrene.

Over the past few decades, the overuse of antibiotics has raised concerns about drinking water and potential health risks, especially the hydrochloride tetracycline (TC-HCl). Therefore, it is crucial to develop a simple, low-cost and high-efficiency photocatalyst for the degradation of the pollutant. A novel photocatalyst with an S-scheme heterojunction structure of AgIn 5 S 8 and Bi 2 MoO 6 was synthesized by using a solvothermal method. The heterojunction photocatalyst obtained demonstrates superior photocatalytic degradation activity for hydrochloride tetracycline (TC-HCl) under visible light irradiation. It exhibits higher photocatalytic degradation performance than pure AgIn 5 S 8 and Bi 2 MoO 6 under the same conditions. The heterojunction with 3 % AgIn 5 S 8 exhibited the highest degradation efficiency of 63.65 % within 40 minutes. Furthermore, the degradation rate is 6.21 times higher than that of AgIn 5 S 8 and 2.18 times higher than that of Bi 2 MoO 6 . The improved photocatalytic activity is primarily attributed to the enhanced light absorption and the high rate of carrier separation resulting from S-scheme heterojunctions.

The accurate monitoring of vital physiological parameters, exemplified by heart rate, respiratory rate, and intracranial pressure (ICP), is of paramount importance, particularly for managing severe cranial injuries. Despite the rapid development of implantable ICP sensing systems over the past decades, they still suffer from, for example, wire connection, low sensitivity, poor resolution, and the inability to monitor multiple variables simultaneously. Here, we propose an ultrasensitive multimodal biotelemetric system that amalgamates an iontronic pressure transducer with exceptional point (EP) operation for the monitoring of ICP signals. The proposed system can exhibit extraordinary performance regarding the detection of minuscule ICP fluctuation, demonstrated by the sensitivity of 115.95 kHz/mmHg and the sensing resolution down to 0.003 mmHg. Our system excels not only in the accurate quantification of ICP levels but also in distinguishing respiration and cardiac activities from ICP signals, thereby achieving the multimodal monitoring of ICP, respiratory, and heart rates within a single system. Our work may provide a pragmatic avenue for the real-time wireless monitoring of ICP and thus hold great potential to be extended to the monitoring of other vital physiological indicators.
