Aims/Purpose: Recent basic and clinical research evidence suggests that male–female differences may influence retinal function and structure. It is also well-established that diabetes affects retinal function. This work aimed to assess whether type 1 diabetes differentially affects neuroretinal function in male and female Wistar rats. Methods: To induce type 1 diabetes, male and female Wistar rats were injected (i.p.) with streptozotocin (65 mg/kg). Electroretinograms (ERGs) were recorded before and 1, 2, and 4 weeks after diabetes induction ( n = 12–13 animals/group). To assess the effect of chronic hyperglycemia on the content of molecular components of the blood-retinal barrier (BRB), specific tight junction proteins were assessed by Western Blotting. Neuroinflammation was evaluated by measuring the retinal levels of pro-inflammatory cytokines. Results: Some sex-related changes in retinal function were detected in the diabetic animals. Overall, in male diabetic rats, compared to control male rats, the differences found under scotopic conditions were mainly in the positive scotopic threshold response (pSTR), with decreased amplitudes (at weeks 2 and 4), and higher latencies (at weeks 1 and 4). In contrast, diabetic female rats, compared to control females, presented a higher increase in the latency value of the negative STR (nSTR; at weeks 1 and 4), a-wave (at weeks 1, 2, and 4), and oscillatory potentials 2, 3, and 4 (at weeks 1, 2, and 4). Under photopic conditions, male diabetic rats showed higher implicit time values of the fundamental flicker wave (at week 4) and a decrease in the amplitude of the flicker 2nd harmonic (at week 4) compared to control males. Conversely, in diabetic female rats, there were no differences in these parameters compared to control female rats. Concerning the BRB and neuroinflammation, no changes were found in diabetic males and females compared to their respective controls. Conclusions: Our findings suggest that type 1 diabetes diff

This study investigates the size-induced axial segregation of binary mixtures in rotating drums, particularly focusing on the effect of drum length. The results indicate that long drums require more time to achieve stable segregation and form more segregation bands. The core region under the free bed surface remains predominantly filled with small particles, indicating that radial segregation occurs simultaneously with the axial segregation. The angle of repose of large particle bands is consistently greater than that of small particle bands, which drives the migration of large particles. Short drums are more sensitive to changes in rotational speed, while long drums with moderate rotational speed promote the formation of segregation bands. The width of small particle bands shows an increasing–decreasing-stabilizing trend with the drum length increasing. An analysis of particle velocities reveals that the characteristics of segregation bands are closely related to the relative velocity difference between large and small particles.

Halide perovskites have received attention in the field of photocatalysis owing to their excellent optoelectronic properties. However, the semiconductor properties of halide perovskite surfaces and the influence on photocatalytic performance have not been systematically clarified. Now, the conversion of triose (such as 1,3-dihydroxyacetone (DHA)) is employed as a model reaction to explore the surface termination of MAPbI3. By rational design of the surface termination for MAPbI3, the production rate of butyl lactate is substantially improved to 7719 μg g−1 cat. h−1 under visible-light illumination. The MAI-terminated MAPbI3 surface governs the photocatalytic performance. Specially, MAI-terminated surface is susceptible to iodide oxidation, which thus promotes the exposure of PbII as active sites for this photocatalysis process. Moreover, MAI-termination induces a p-doping effect near the surface for MAPbI3, which facilitates carrier transport and thus photosynthesis. © 2020 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim

Municipal solid waste（MSW） is an important destination for abandoned plastics. During the waste disposal process, large plastic debris is broken down into microplastics（MPs） and released into the ***, current research only focuses on landfill leachates, and the occurrence of MPs in other leachates has not been studied. Therefore, herein, the abundance and characteristics of MPs in three types of leachates, namely, landfill leachate, residual waste leachate, and household food waste leachate, were studied, all leachates were collected from the largest waste disposal center in China. The results showed that the average MP abundances in the different types of leachates ranged from（129 ± 54） to（1288 ± 184） MP particles per liter(particles.L-1) and the household food waste leachate exhibited the highest MP abundance（p < 0.05）. Polyethylene（PE） and fragments were the dominant polymer type and shape in MPs, respectively. The characteristic polymer types of MPs in individual leachates were different. Furthermore, the conditional fragmentation model indicated that the landfilling process considerably affected the size distribution of MPs in leachates, leading to a higher percentage（> 80%） of small MPs（20–100 μm） in landfill leachates compared to other leachates. To the best of our knowledge, this is the first study discussing the sources of MPs in different leachates, which is important for MP pollution control during MSW disposal.

Developing efficient catalysts for microwave-assisted co-pyrolysis of biomass and plastics (BP) is crucial for producing high-value products. This study introduces the design and synthesis of an enhanced Fe@C catalyst using MIL-101(Fe) as the precursor. During precursor preparation, different amounts of bamboo-based pyrolytic char (BC) were incorporated, and both conventional and advanced microwave carbonization techniques were employed to produce the Fe@C catalysts. Simultaneously, various characterization techniques were employed to analyze the physicochemical properties of the catalysts. The catalytic performance of the catalyst was evaluated in the microwave-assisted co-pyrolysis of bamboo and polyethylene, focusing on the distribution of pyrolysis gases and bio-oil products. The results showed that incorporating BC and applying microwave carbonization significantly enhanced the catalyst's selectivity for H2 and aromatic hydrocarbons. Notably, the Fe@C-8BC catalyst achieved the highest H2 content (55.65 vol%) and aromatic hydrocarbon content (28.07 %), with MAHs accounting for 51.8 % of total aromatics. Furthermore, the microwave-carbonized Fe@C catalyst exhibited superior BTEX selectivity, with a BTEX/aromatic ratio of 32.2 %. This study highlights the benefits of integrating BC and advanced microwave carbonization techniques in the preparation of MOF-derived catalysts, providing valuable insights for optimizing co-pyrolysis catalysts and advancing the synthesis of high-value products from waste materials. © 2025

Converting methanol to high-value formate through electrochemical methods can significantly reduce the energy consumption associated with conventional production processes. In this study, we directly synthesized iron-doped cobalt phosphate (Fe-CoPO) on nickel foam (NF) to achieve excellent activity for the methanol electro-oxidation reaction (MOR). Our results demonstrated that Fe-CoPO produced a current density of 100 mA·cm−2 at a significantly low operating potential of 1.436 V (vs. reversible hydrogen electrode (RHE)) and operated steadily for 16 h at this current density with a Faradaic efficiency (FE) of 97%. Furthermore, Fe-CoPO maintained a high FE of 100% even at an extremely high current density of 300 mA·cm−2 for 8 h. We found that the high MOR activity of Fe-CoPO results from electrochemical reconstruction to generate the Co2+/3+–O bond. The heterogeneous interface between Fe and Co inhibits the formation of Co4+, which significantly enhances the MOR activity. Thus, this work not only provides insights into the mechanism of MOR over Co-based catalysts but also offers a novel direction for developing highly active MOR catalysts. © The Author(s) 2025.

Nanoplastics (NPs) can be absorbed by crop roots and translocated to shoots, but whether the process follows a unidirectional pathway in different plant species remains unclear. This study investigated the translocation and accumulation of europium-labeled polystyrene NPs in cucumber (dicot) and maize (monocot) seedlings using a split-root system. The results showed that NP accumulation was highest in exposed roots (E-R), followed by unexposed roots (UE-R), and then shoots in both plants. In cucumber, NP accumulation in E-R was 26.84 % higher than in maize; while in maize, the translocation factor from shoot to UE-R was 4.45 times greater than in cucumber. TEM images confirmed NP transport from root to shoot via xylem, while confocal images showed the redistribution of NPs from shoot to root via phloem. AgNO treatment (5-50 μmol L) revealed aquaporin-mediated regulation of NP accumulation, with concentration-dependent increases of 30.37-220.7 % in cucumber roots and 36.38-53.65 % in maize shoots. Transcriptomic analysis revealed that NP accumulation interacted with aquaporin gene expression, where differential regulation of tonoplast intrinsic, plasma membrane intrinsic, and nodulin 26-like intrinsic proteins drove translocation differences. This study offers critical insights into the "root-to-shoot-to-root" translocation of NPs, informing crop safety assessments amid global plastic pollution.

With the advances in optical sensing and image capture systems, process images certainly offer new perspectives to process monitoring. Compared to the process data collected by traditional sensors at local regions, process images, which can capture more significant variations in the whole space, enhance the monitoring performance in data-driven monitoring methods. In this paper, a popular deep learning method, namely deep belief network (DBN), is applied to effectively extract useful features from the images. Meanwhile, a new statistic is developed for the DBN model, which integrates feature extraction and fault detection into one model rather than separately accomplish them. The effectiveness of the proposed DBN based monitoring method is demonstrated in a real combustion system. © 2018
