The approach combines finite element-based numerical modeling, experimental modal analysis, and advanced signal processing-assisted deep learning to achieve reliable loosening detection under operational excitations. First, a finite element model of the bolted flange pipe is developed and updated using experimentally identified natural frequencies to establish a validated digital twin. The dynamic responses of healthy and loosened bolt conditions are then simulated and experimentally measured. To extract fault-sensitive features, the vibration signals are decomposed using a Haar filter bank, followed by transformation into the time–frequency domain using the Smoothed Pseudo Wigner– Ville distribution (SPWVD). The resulting time–frequency representations are subsequently used to train a convolutional neural network (CNN). A key contribution of this study lies in the hybrid digital twin learning strategy, in which CNN training is performed using numerical data and healthy experimental data. At the same time, fault classification is conducted under experimental loosening conditions.

A theoretical model incorporating the stroke-dependent gap flow dynamics is established, and a finite element analysis of the internal magnetic field distribution is conducted. Numerical results indicate that the magnetic flux lines are concentrated by the converging geometry of the buffer zone, increasing the magnetic flux density by 17.4% without additional power input. Experimental validations utilizing a servo-hydraulic testing system are performed, and the experimental results show good agreement with the theoretical predictions. Specifically, the damping force remains stable within the damping zone. As the piston enters the buffer zone, the damping force increases significantly with displacement. Through the passive self-reinforcement mechanism, the peak damping force is effectively elevated from 2240 N in the damping zone to a maximum of 4296 N.

ZnO incorporated TiO₂/carbon nanocomposites were synthesized via the sol–gel route by systematically changing the TiO₂:ZnO mass ratio. The nanocomposites exhibited a reduction in band gap energy values and particle size as ZnO content increased. The photocatalytic performance of the synthesized materials was tested for degrading sulfasalazine (SUZ) and losartan potassium (LP) under visible light and sunlight conditions. The ZnO@TiO₂/carbon (with a 1:0.075 mass ratio of TiO₂:ZnO) nanocomposite with a band gap energy of 3.23 eV demonstrated maximum degradation efficiencies of 97% and 96% for SUZ and LP, respectively, under sunlight illumination within 120 min. The photocatalytic degradation of SUZ was studied using radical scavengers and EPR spin-trap experiments. The findings indicate that superoxide (O₂^⋅−), holes from valence band (h_vb⁺) and adsorbed hydroxyl radicals (^⋅OH_ads) are the primary reactive species involved in the degradation of SUZ. Catalyst reuse was demonstrated up to three cycles. The photocatalytic performance was further evaluated in a synthetic wastewater matrix containing representative inorganic ions and natural organic matter, where the CTZ5 nanocomposite maintained appreciable degradation efficiency. ESI/MS based mechanistic studies identified 4-nitro-<i>N</i>-(2-pyridinyl)benzenesulfonamide and sulfapyridine as key intermediates.

Herein, castor oil (CO) and tea seed oil (TSO) were selected as feedstocks to fabricate bio-based hydrophilic chain extenders (HCEs) for water-based polyurethane (WPU). Firstly, the raw oils were treated through a three-step process involving saponification, acidification and urea inclusion purification, yielding unsaturated ricinoleic acid (RA) and oleic acid (OA) with high purities of 93.99% and 92.72%, respectively. Subsequently, an efficient thiol-ene click reaction was carried out to prepare amphiphilic ricinoleic acid-based chain extender (RACE) and amphiphilic oleic acid-based chain extender (OACE) under ambient conditions (1 h, room temperature) with relatively lower molecular weight (<i>M</i>_w) and accurate functionality (<i>f</i>_− OH<i>= 2</i>). The activation energies for the reactions of RACE/OACE and dimethylolpropionic acid (DMPA) with isophorone diisocyanate (IPDI) were evaluated via non-isothermal DSC kinetic analysis (Kissinger method and Ozawa method), and the apparent activation energy (<i>Ea</i> from Kissinger/<i>Eo</i> from Ozawa) values were found to be 76.66/78.88 kJ·mol⁻¹ for RACE and 74.58/76.91 kJ·mol⁻¹ for OACE, respectively, which were slightly higher than that of DMPA (Ea/Eo = 73.01/75.32 kJ·mol⁻¹). Application of these bio-HCEs for preparing WPU revealed that the particle size and absolute zeta potential of emulsion with more than 0.0248 mol bio-HCEs were equivalent to those of the emulsion with 0.0192 mol DMPA, and the resultant WPU films showed enhanced broken elongation, increased water contact angles, and reduced water absorption ratio.

Currently, the commonly used methods for collagen extraction are acid treatment, alkaline treatment, or enzymatic hydrolysis. However, these approaches often compromise the native molecular structure and generate significant environmental burdens. As one of the green, and highly efficient extraction strategies, ionic liquids (ILs) technology has emerged as a promising direction. This work first outlines the advantages of the ILs extraction method over other extraction techniques. The IL extraction method can enhance collagen yield, and its extraction process is more environmentally friendly and economical. Subsequently, it reviews recent advances in collagen extraction from skins and leather using ILs, emphasizing their role in enhancing collagen yield. The work summarizes the mechanism whereby ILs disrupt hydrogen bonds and ionic bonds stabilizing collagen molecular structures, thereby forming reversible new interactions to facilitate extraction. It was found that ILs have significant advantages in the application of collagen-based materials. In addition to improving the extraction efficiency of collagen, ILs can also promote the functionalization modification of collagen. It can not only regulate the microstructure and mechanical properties of collagen, but also give collagen antibacterial, conductive and other functions. Meanwhile, due to the low volatility, low toxicity and recyclability of ILs, the cost and environmental risks are greatly reduced. Particular attention is given to practical applications in drug delivery systems, tissue engineering, flexible sensors, and leather industry, underlining the broad technological relevance of this approach. Finally, we identify current limitations and outline future research directions.
