The combination of organic and inorganic coagulants is considered to be an effective strategy for Humic Acid (HA) removal. In this study, the performance of Titanium-based coagulants aided by Cationic-Polyacrylamide (CPAM) to HA molecules was compared. It was found that CPAM had a higher promotion effect in the TXC system. The reason for why CPAM was more suitable for the TXC system could be explained by analyzing Zeta potential , FTIR, and XPS . By comparing the coagulation mechanism of TiCl 4 (TC) and Poly-Titanium Chloride (PTC), we found that complexation was the main mechanism of TC and PTC in acidic and neutral environments. The C-O-Ti Bond was formed by complexing the Ti-OH with the C-OH and -COOH functional groups of HA molecules. Sweeping was the most important removal mechanism of TXC in the neutral and alkaline environment, and CPAM bridged floc through hydrogen bond force for enhancing the sweeping effect. In addition, the role of CPAM in TXC system was further demonstrated by Zeta potential analysis. Both TC and PTC were positively charged in the measured pH range, so the removal of Humic acid was limited by increasing zeta potential. In both neutral and alkaline environments, TXC kept a negative surface charge and CPAM significantly enhanced the adsorption of HA on the TXC floc surface. This study provided clues for the interaction mechanism between titanium salt coagulants and HA, and it also provided a reference for the application of TXC coagulant combined with CPAM flocculant for the removal of HA molecules.

Acute kidney injury (AKI), a critical clinical syndrome marked by high incidence and mortality, is currently diagnosed mainly by serum creatinine (SCr) and blood urea nitrogen (BUN), which have high miss rates. This study innovatively proposes using urinary hydrogen peroxide (H 2 O 2 ) concentration changes, caused by renal oxidative stress in AKI, as a new indicator for AKI risk assessment and treatment monitoring. Results from in vitro and AKI animal models show this indicator can quickly monitor AKI onset and drug effects in mice via electrochemical sensing technology based on Bi 2 S 3 @Cu 0.1 , offering a novel approach for AKI diagnosis and rehabilitation monitoring.

Tendinopathy (TDP) is a common yet challenging chronic degenerative condition characterized by disrupted inflammatory microenvironments, cellular dysfunction and tissue structural degradation. Drawing inspiration from the protective and drug-releasing functions of adhesive bandages, this study has developed a biomimetic “Tendon Band-Aid” using electrospinning and photocrosslinking techniques to modulate anti-inflammatory and regenerative processes within the tendon microenvironment. Gelatin methacrylate and gelatin vanillin hydrogel fibers (GV) were used as nanofiber patches to cover damaged tendons, enabling the sustained release of ibuprofen (ibu) within the local inflammatory microenvironment. In vitro experiments confirmed that the biomimetic “Tendon Band-Aid” (GV@ibu) effectively alleviates local inflammatory responses by inhibiting the AGEs/NF-κB/COX-2 pathway and guiding tendon stem cells (TSCs) towards tenogenic differentiation. It also promotes the reorganization of the extracellular matrix (ECM). In vivo studies further demonstrate the patch’s ability to significantly improve collagen tissue structure and restore motor function in tendinopathy models. Consequently, this multifunctional GV@ibu patch, which combines inflammation resolution and tenogenesis, shows great potential as an ideal solution for the regenerative repair of tendinopathies.

TiO 2 ceramics co-doped with In and Nb exhibit unusual large dielectric-permittivity phenomena, but their sintering temperature is essentially higher than 1400 °C and the holding time is usually longer than 5 h, which is very uneconomical for industrial production and practical applications. Therefore, to maintain the relatively good dielectric properties of In and Nb co-doped TiO 2 ceramics and reduce the sintering temperature to about 1300 °C, B 2 O 3 , was added as a sintering aid to prepare B 2 O 3 /(In 0.5 Nb 0.5 ) 0.05 Ti 0.95 O 2 ceramics in this paper. The crystalline structures, microstructures, and electrical properties were investigated and discussed. The results showed that the sintering temperature of B 2 O 3 /(In 0.5 Nb 0.5 ) 0.05 Ti 0.95 O 2 ceramics indeed prominently decreased, but their dielectric loss was relatively large, possibly caused by the pores left following B 2 O 3 volatilization.

Ce 0.8 Nd 0.2 O 1.9 (NDC) and La 0.8 Sr 0.2 Ga 0.8 Mg 0.2 O 3-δ (LSGM) electrolytes were prepared using a sol-gel method. NDC-LSGM composite electrolytes were subsequently prepared by adding 5% ( w , mass fraction) precalcined LSGM powders to NDC sols. The electrolyte materials of NDC-Co and NDC-LSGM-Co were obtained by adding 1 mol% CoO to NDC sols and NDC-LSGM composite electrolytes, respectively. The microstructure and phase composition of the pellets were characterized using X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), and energy dispersive X-ray spectroscopy (EDS). The electrical conductivities of the pellets were measured using alternative current (AC) impedance spectroscopy . The results indicate that a single perovskite phase is observed for the LSGM ceramic, while NDC-Co, NDC-LSGM and NDC-LSGM-Co have a cubic fluorite structure similar to that of NDC. As a sintering aid , CoO can further promote grain growth and increase relative density (＞95%) of the NDC-LSGM composite electrolyte. The enhancement of the total conductivity is primarily attributed to the large increase in the conductivity of the grain boundary. However, the slight decrease of the grain boundary conductivity of the NDC-LSGM-Co electrolyte is caused by the presence of trace amounts of impurity phases in the grain boundaries.

In this study, the influences of different aid-sintering additives on the synthesis of β-SiAlON:Eu2+ phosphor were investigated. The aid-sintering additives include oxides, fluorides, chlorides, and carbonates. The β-SiAlON:Eu2+ phosphor, synthesized using different additives, was investigated in detail via spectroscopic data, X-ray diffraction, quantum efficiency, and scanning electron microscopy; the particle morphology and spectroscopic properties improved with the addition of different additives. Different additives have different influences on the morphology of β-SiAlON:Eu2+. Most oxide additives increase the diameter of β-SiAlON:Eu2+. Most fluoride additives increase the length of β-SiAlON:Eu2+. Particles with different morphologies can be obtained by adjusting the quantities of the oxide and fluoride additives. When combined with red phosphors, β-SiAlON:Eu2+ will produce wider color gamut backlights than the traditional yttrium aluminum garnet.

Tooth defects are regarded as “wounds” on the tooth. While remineralization therapies aim to rebuild tooth structures, challenges remain in protecting defects and delivering remineralization templates due to the wet and dynamic oral environment. Drawing from wound dressing, this study intends to construct a tooth dressing for the oral environment. Tannic acid (TA) was screened to crosslink fibroin protein (SF) and form internal anchoring through hydrogen bonding to fabricate a SF-TA (ST) tooth dressing matrix. Assisted by the drainage effect of the SF hydrophobic side chain on the interface, the system forms external anchoring to the tooth surface via phenolic hydroxyl groups and side chains. Notably, the bidirectional anchoring effect can be enhanced by calcium-phosphorus-enriched saliva, ensuring effective wet adhesion in the oral cavity. Loaded with an octuplet repeat of aspartate-serine-serine (8DSS) as a remineralization template, the SF-TA-8DSS (ST-8DSS) “tooth band-aid” maintains strong wet-adhesion to tooth surface under liquid contamination (bursting pressure above 780 mmHg) and delivers 8DSS into dentinal tubules (up to 100 µm over 14 days), promoting dentin remineralization. The proposed tooth band-aid offers an effective strategy for repairing tooth defects, combining mechanical reinforcement and wet adhesion through bidirectional anchoring for sustained mineralization under fluid contamination.

Real-time monitoring of pressure and temperature in wheelchair patients is an effective method for preventing and rehabilitating pressure injuries. Nevertheless, few rehabilitation devices capable of monitoring temperature and pressure have been reported. Herein, we propose a fully textile-based scalable and designable dual-mode rehabilitation cushion for real-time monitoring of pressure and temperature. The different signal output modes (resistive and capacitive signals) enable noninterference between pressure and temperature. The cushion exhibits a wide pressure monitoring range of 2–160 kPa, a high sensitivity of 8.8399 kPa −1 , and a repeatable stability exceeding 10,000 cycles. In addition, the cushion demonstrates excellent temperature responsiveness with a linearity of 0.995 and a TCR of 0.019 s°C −1 . Furthermore, an intelligent monitoring system integrated with machine learning has been developed to realize large-range multipoint sensing and data visualization. The system can accurately recognize different sitting postures with an accuracy of 99.65%. Human application evaluations have demonstrated the feasibility of this cushion for preventing pressure injuries, which can stimulate further research on pressure injury prevention and rehabilitation in the future.

In this paper, ZnO was used as a sintering aid as well as reactant in the reactive flash sintering (RFS) of zinc-containing ceramic materials at room temperature (25 °C). The RFS of ZnO-based ceramics, both ZnAl 2 O 4 and Zn 2 TiO 4 , were achieved with the application of a high electric field. Contrary to previous reports, the RFS of ZnAl 2 O 4 was divided into two stages according to temperature changes, and the effect of the reaction exotherm on the RFS was presented for the first time in this paper. In addition, the RFS produced a larger grain size of ZnAl 2 O 4 than conventional sintering did.

Biomass-derived 2,5-dimethylfuran (DMF) is an ideal, renewable gasoline additive, and its production with high productivity is highly desirable. A continuous production route was developed to yield DMF from fructose via a tandem strategy, where dehydration catalysts (HY zeolite and niobium phosphate) assisted by 1-butyl-3-methylimidazolium chloride ([BMim]Cl) and hydrodeoxygenation (HDO) catalyst Cu–Ru/C were integrated into one reaction system with γ-butyrolactone (GBL) as the mobile phase. Optimum conditions, such as temperature, H2 pressure, weight hourly space velocity, and [BMim]Cl concentration, were investigated systematically, with an initial HDO study by using 5-hydroxymethylfurfural (HMF) as substrate and subsequent tandem dehydration and HDO to produce DMF with fructose as substrate. Among the conditions, the highest yield of DMF at 55.2% was gained by niobium phosphate and Cu–Ru/C, with the aid of [BMim]Cl in a fixed bed. Meanwhile, [BMim]Cl facilitated fructose dehydration to HMF and also mediated HDO of the resultant HMF by stabilization, which was clarified by 1H NMR and FTIR spectroscopy. Finally, the fact that carbon deposit led to catalyst deactivation was examined thoroughly via a series of characterization techniques. This work achieved continuous DMF production from fructose and laid a foundation for future possible amplification of DMF.

Carbon dots (CDs) have wide application potentials in optoelectronic devices, biology, medicine, chemical sensors, and quantum techniques due to their excellent fluorescent properties. However, synthesis of CDs with controllable spectrum is challenging because of the diversity of the CD components and structures. In this report, machine learning (ML) algorithms were applied to help the synthesis of CDs with predictable photoluminescence (PL) under the excitation wavelengths of 365 and 532 nm. The combination of precursors was used as the variable. The PL peaks of the strongest intensity ( λ s ) and the longest wavelength ( λ l ) were used as target functions. Among six investigated ML models, the random forest (RF) model showed outstanding performance in the prediction of the PL peaks.
