Surface heating membrane distillation overcomes several limitations inherent in conventional membrane distillation technology. Here we report a successful effort to grow in situ a hexagonal boron nitride (hBN) nanocoating on a stainless-steel wire cloth (hBN-SSWC), and its application as a scalable electrothermal heating material in surface heating membrane distillation. The novel hBN-SSWC provides superior vapour permeability, thermal conductivity, electrical insulation and anticorrosion properties, all of which are critical for the long-term surface heating membrane distillation performance, particularly with hypersaline solutions. By simply attaching hBN-SSWC to a commercial membrane and providing power with an a.c. supply at household frequency, we demonstrate that hBN-SSWC is able to support an ultrahigh power intensity (50 kW m−2) to desalinate hypersaline solutions with exceptionally high water flux (and throughput), single-pass water recovery and heat utilization efficiency while maintaining excellent material stability. We also demonstrate the exceptional performance of hBN-SSWC in a scalable and compact spiral-wound electrothermal membrane distillation module.A hexagonal boron nitride nanocoating grown directly on a stainless-steel mesh enables ultrahigh power input intensity in an electrothermal membrane distillation system to desalinate hypersaline solutions with exceptionally high water flux, single-pass water recovery and heat utilization efficiency.

The skylights in the cross-connection hall of Zurich Main Station require replacement due to wear and damage. While safety regulations prohibit new wire mesh glass, heritage guidelines mandate a visually similar alternative. To identify suitable laminated safety glass options, this study combines light scattering measurements, daylight simulations, and luminance analyses. A key factor was the light scattering effect of the original wired glass, which influences the perception of brightness and glare under varying daylight conditions. Measurements using a scanning gonio-photometer quantified these properties for both the historic glass and potential replacements. Single-pane glass samples were optically coupled in a reversible manner to allow for flexible testing. A Radiance-based daylight simulation model was developed to assess the impact of different glass variants on luminance levels from multiple viewpoints inside the hall. The evaluation focused on the percentage of skylight areas that light up under direct sunlight, that is, exceeding luminance thresholds. These are visualized in annual heatmaps. Two glass variants were shortlisted based on their similarity to the original glass in terms of light scattering behaviour. Laminated samples of each were produced, measured, and evaluated to confirm reproducibility. Both options performed well in direct comparison, and the final selection was based on manufacturability and cost-effectiveness. The chosen glass ensures compliance with safety standards while preserving the hall’s historic appearance, demonstrating that a careful balance between heritage conservation and modern requirements is achievable.

In order to evaluate the passing performance of the wire mesh screen wheel designed for the lunar mobile platform, a beam element co-node method was proposed to build the finite element model of the wheel net according to its special wheel net structure. The wheel net model built by the beam element co-node method not only ensures the mesh quality and wire cross-section characteristics, but also greatly reduces the number of meshes compared with the direct meshing of the model. The lunar soil discrete element particle model and the screen wheel finite element model were set up in LS-DYNA for the joint working conditions. The screen wheel designed according to the lunar platform has a sinking amount of less than 10% of the wheel diameter and a driving torque of less than 10.2N•m under various working conditions, which proves that the wheel has good passing performance.

To prove the effectiveness and accuracy of particle swarm optimization (PSO) algorithm for parameter identification of steel wire mesh mat isolator. The influence of different loading conditions on the mechanical properties of steel wire mesh gasket elements was investigated. The sinusoidal loading test was carried out to obtain the test response data. The mechanical properties of the wire mesh mat are described by a double-fold model, and the parameter identification equation of the isolator is established. The model parameters are identified by particle swarm optimization and test response data. It is proved that the hysteresis curves calculated by the identified parameters agree well with the experimental results. It is proved that the particle swarm optimization algorithm is effective and accurate for the parameter identification of steel wire mesh mat isolator. It is a parameter identification method with engineering application value.

The characteristics and evolution of two-phase flow are of critical importance to the safety of pressurized water reactors. Based on the double-layer wire mesh sensors in this paper, the air-water two-phase flow experiment of the 3×3 rod bundle channels is carried out at room temperature and pressure. The results show that the critical bubble diameter range for the reversal of lateral lift direction is 4 to 5.8 mm. In addition, the time-averaged void fraction for bubbly flow reveals a wall peak distribution at lower superficial gas velocities and shifts to a core peak as these velocities increase. For cap flow, the cross-distribution of cap bubbles within adjacent subchannels triggers large-scale mixing of the liquid phase between adjacent subchannels. For slug flow, large-sized bubbles develop along the axis and cross subchannel gaps to aggregate into slug-shaped bubbles, with a more pronounced distribution of the central peak of void fraction. The drift-flux models are evaluated against the experimental data, and the Ozaki model demonstrates higher precision in estimating void fraction, exhibiting a deviation of 9.8% on average.

Porous metal materials are applied in various industries, among which powder rolling is the most widely used process for preparing porous metal materials. Then, metal porous materials prepared solely from powder as raw materials have the disadvantage of low mechanical properties, while wire mesh as reinforcement can effectively improve tensile strength. The preparation process of wire mesh powder composite is complex and requires the addition of adhesives. In this article, the mechanical properties of thin metal strips prepared by powder and wire mesh composite vertical rolling were much higher than those prepared by pure powder. Moreover, this thin strip had porous characteristics, and the preparation process was simple and easy to promote. This research could provide a reference for the powder metallurgy field, especially for the preparation of metal porous materials by vertical rolling.

Finally, the application and technical effect of the smooth aluminum sheath are analyzed, which provides a reference for the production and practical engineering application of the smooth aluminum sheath technology.

Increase in growth of construction industry is eventually leading to a rise in output of Portland cement which in turn increases the pollution. This has effect on global warming. As to reduce the effect of green-house gases, sustainable materials are being used in concrete intensively. One among which is the Geo-polymer concrete (GPC). In this project steel wire mesh has been inculcated into GPC forming “Ferro Geo-polymer concrete (FGPC)”. Specimens have been cast using GPC inculcated with various layers of wire mesh. Ferro geo-polymer concrete specimens were cast with wire mesh in single and double layers and values are compared with same grade of conventional GPC specimens. Mechanical properties of G40 grade Ferro geo-polymer concrete have been studied at the age of 28, 56 and 90 days. It is found that for double layer at 90 days of ambient curing maximum percentage increase of 10.18%, 10.37% and 27.46% in compressive, split tensile and flexural strengths correspondingly. The evaluated values are compared with values of ML (MATLAB) application and achieved accuracy of more than 98%.

The design of the hydraulic manifold block is time-consuming, laborious, and prone to make mistakes due to the vertical intersection and dense complexity of its internal oil passage network. The mathematical optimization model of this problem is given based on the comprehensive analysis of the structural characteristics and design rules of the internal orifices of the hydraulic manifold block. Using the integrated circuit layout algorithm for reference, an optimization design method of a multi-wire mesh channel network based on routing sequence optimization is proposed and verified by an example. The research results show that the optimization of the connection order between multiple wire networks at both ends and the routing order between multiple wire networks in a single-wire network can not only achieve the optimal design of the connectivity of the single-wire network but also ensure the optimal connectivity result of the entire hole network. At the same time, as the bottom core algorithm of the integrated block layout optimization design, it can provide a powerful technical guarantee for improving the integrated block design level, quality, and automation.

Crop foraging by primates is a prevalent form of human-wildlife conflict, especially near protected areas. This behavior poses significant economic challenges for subsistence farmers, jeopardizing both livelihoods and conservation efforts. This study aimed to assess patterns of primate crop-foraging events and estimate maize damage in protected and unprotected fields in southern Ethiopia. Data were collected over 12 months between 2020 and 2021 in the Sodo Zuriya and Damot Gale districts of Southern Ethiopia. A team of six field experts and 25 farmers participated in the study, during which maize damage inflicted by primates was assessed using 25 deployed camera traps. Linear mixed models were used to explore the relationship between maize damage by primates and spatio-temporal variables. Olive baboons and grivet monkeys were found to target maize more frequently during June, July, and August. Olive baboons forage in the morning, while grivet monkeys do so in the afternoon. The average maize yield losses due to primate damage were 43.1% in protected fields and 31.4% in unprotected fields. Of the total damage, 43.1% occurred in protected fields situated 50 meters from the forest edge. Conversely, unprotected fields experienced lower rates of damage: 14.4%, 13.2%, 3.7%, and 0.1% at distances of 50 m, 100 m, 200 m, and 300 m from the forest edge, respectively. Camera traps captured 47 photos of baboons, 21 photos of grivet monkeys, and documented eight primate crop-foraging events. This study revealed that maize fields within 50 meters of the forest edge faced significant damage. Despite the use of wire mesh fencing, it was largely ineffective in deterring olive baboons and grivet monkeys. Additionally, while human guarding is often considered an effective protective strategy, these findings suggest its ineffectiveness due to inconsistent implementation. Overall, this study provides valuable insights for promoting primate conservation and mitigating human-primate conflicts.
