Rapeseed, as one of the most important sources of vegetable oil in the world, the effects of size and concentration of micro-nano plastics and the conditions after increased ultraviolet radiation on the growth and genetics of its seedlings remain unclear. Herein, we studied the biological distribution of polystyrene plastic micro/nano-plastics (PS-M/NPs) with three varying concentrations and diameters under greenhouse light and ultraviolet light during the growth of rape seedlings and the related gene changes. The results demonstrated that the stress caused by PS-M/NPs on rape seedlings was greater under ultraviolet light than that under greenhouse light. The effect of 25 nm 100 mg/L PS-NPs on rape seedlings was more significant and the crop height and root length decreased by 13.57 % and 27.58 % compared to the blank group. Due to the impairment of photosynthesis, the chlorophyll content decreased by 59.09 %, and soluble sugar content increased by 43.80 %, while the soluble protein content did not change significantly. Additionally, the activity of catalase, superoxide dismutase, peroxidase, and the content of malondialdehyde increased by 43.22 %, 103.94 %, 18.41 %, and 54.37 %, respectively. Transcriptome analysis revealed that PS-M/NPs primarily affected the oxidative stress pathway in rape seedlings, leading to a decrease in the content of metabolic substances and ultimately impacting crop growth and disease resistance. Moreover, the effects of microplastics on the growth and gene regulation of rape seedlings were intensified with increased UV irradiation.

Balancing electrochemical activity and structural reversibility of fibrous electrodes with accelerated Faradaic charge transfer kinetics and pseudocapacitive storage are highly crucial for fiber-shaped supercapacitors (FSCs). Herein, we report novel core–shell hierarchical fibers for high-performance FSCs, in which the ordered NiCoMoS nanosheets arrays are chemically anchored on Ti 3 C 2 T x fibers. Beneficial from architecting stable polymetallic sulfide arrays and conductive networks, the NiCoMoS−Ti 3 C 2 T x fiber maintains fast charge transfer, low diffusion and OH − adsorption barrier, and stabilized multi-electronic reaction kinetics of polymetallic sulfide. Consequently, the NiCoMoS−Ti 3 C 2 T x fiber exhibits a large volumetric capacitance (2472.3 F cm −3 ) and reversible cycling performance (20,000 cycles). In addition, the solid-state symmetric FSCs deliver a high energy density of 50.6 mWh cm −3 and bending stability, which can significantly power electronic devices and offer sensitive detection for dopamine.

Protein hydrogels is an important biomaterial for soft tissue repair in biomedical applications. However, the most extracellular matrixes are structured and ordered, the morphology of common hydrogels are of random network structures that impeded their applications in tissue engineering. In this study, silk fibroin hydrogels with different morphologies (i.e., microspheres, regularized beads, nano/micro fibers, intertwined networks, and multi-walls) were prepared under low voltage electrostatic fields by regulating the concentration of silk fibroin solution. Additionally, their stability can be regulated with further processing routes to satisfy the tailored requirements for different applications. Fourier transform infrared spectrometer (FTIR) and X-ray diffraction (XRD) provided evidence of the stability of silk fibroin electro materials was tuned by this method effectively. Therefore, these silk fibroin electro hydrogels with various morphologies, high orientation, and stability-regulatable properties provided a promising candidate for tissue engineering.

Regenerated silk fibroin (SF) has excellent biocompatibility and degradability, but its mechanical properties need to be improved. As the most widely distributed and most abundant polysaccharide in nature, the advantage of cellulose material is its good strength and modulus. In this study, SF was dissolved in formic acid and calcium chloride solution. Then glycerol and ultrasonic microcrystalline cellulose were added, and the SF/cellulose blend film was prepared by the delayed flow method. The properties of the blend films were characterized by a series of tests such as electron microscope, FTIR, tensile strength, and so on. The results showed that when the ratio of cellulose to SF reached 30 to 70 and the addition of glycerol was 30% of the total solute, the properties of SF/cellulose blend films were the best. The addition of micro-nano-cellulose fiber improved the mechanical properties of the blend film, and the addition of glycerol greatly improved the flexibility of the blend film, which expanded the application of SF/cellulose blend films in the field of biomaterials.

Ltd. Beijing100081 China

Creep behaviors and microstructure of Ni-based superalloy GH3128 were investigated based on creep tests under 9 different temperature-stress combinations. The underlying deformation mechanisms were discussed through analysis of stress exponents and microstructure evolution. The results indicated that after creep rupture at 850 °C, the microstructure of GH3128 featured significant precipitate formation, high-density dislocation pile-ups, and extensive dynamic recrystallization. Creep deformation was dominated by multiple mechanisms including dislocation climbing, dislocation-precipitate interactions, and grain boundary sliding, corresponding to a high stress-exponent of 8.5. As the testing temperature increased to 950 °C and 1000 °C, the density of precipitates decreased with growth in size. It was accompanied by reduced dislocation density and increased recrystallized grain size. Dislocation climbing controlled creep deformation, in which the stress exponents were respectively 6.1 and 5.5. © 2025 Elsevier B.V.

Polymer electrolytes incorporated with fillers possess immense potential for constructing the fast and selective Li + conduction. However, the inhomogeneous distribution of the fillers usually deteriorates the microdomain consistency of the electrolytes, resulting in uneven Li + flux, and unstable electrode-electrolyte interfaces. Herein, we formulate a solution-process chemistry to in situ construct gel polymer electrolytes (GPEs) with well-dispersed metal–organic frameworks (MOFs), leading to a uniform microdomain structure. Through the integration of X-ray computed tomography analyses and theoretical simulations, our research identifies that the improvement of microdomain consistency in GPEs is beneficial for enhancing its mechanical strength, homogenizing ionic/electronic field distribution and upgrading the interface stability with the elctrodes. Moreover, consistently spread MOFs bind effectively with Lewis-base anions of Li salts, enhancing Li + kinetics. Owing to these advantages, the developed GPEs achieve a high conductivity of 1.51 mS cm −1 and a Li + transference number of 0.66, resulting in exceptional cyclability of lithium metal electrodes (over 1800 hours). Additionally, the solid-state NCM811//Li pouch batteries exhibit an impressive capacity retention of 94.2 % over 200 cycles with an N/P ratio of 1.69. This study emphasizes the significant impact of microdomain structural chemistry on the advancement of solid-state batteries.
