Reducing the contact time between impacting droplets and superhydrophobic surfaces has attracted much attention in recent years due to importance of controlling heat mass transfer. Previous researchers have proposed several methods, such as lifting before retraction, accelerating retraction process, or splashing droplets. One example includes symmetry-breaking surfaces, which were used accelerate droplet realize fast detachment. However, dependence on impact velocity surface structure scale...
Biodegradable polymeric stents have received extensive attention due to the high efficiency in interventional therapy. Fabrication of well‐defined still poses a significant fabrication challenge. This study aims investigate feasibility using homemade three‐dimensional (3D) printing system directly print customized stents. In proposed system, rotating shaft with controllable temperature and speed has been integrated into fused deposition modeling‐based 3D support printed stably situ ....
Water vapor condensation is common in nature and widely used industrial applications, including water harvesting, power generation, desalination. As compared to traditional filmwise condensation, dropwise on lubricant-infused surfaces (LIS) can lead an order-of-magnitude increase heat transfer rates. Small droplets (D ≤ 100 μm) account for nearly 85% of the total droplet sweeping plays a crucial role clearing nucleation sites, allowing frequent re-nucleation. Here, we focus dynamic interplay...
During water droplet impingement onto a rice-leaf-inspired grooved superhydrophobic surface, the unidirectional textures can reduce solid–liquid contact time through modifying impact dynamics. The influence of groove geometry on splashing impacting droplets is still unrevealed. In this study, we experimentally identify bouncing and regimes surfaces varying parameters. Asymmetric spreading retracting are observed surfaces, accompanied by obvious liquid jets generated within grooves. As...
Lubricant-infused surfaces (LISs) can promote stable dropwise condensation and improve heat transfer rates due to a low nucleation free-energy barrier high droplet mobility. Recent studies showed that oil menisci surrounding condensate microdroplets form distinct oil-rich oil-poor regions. These topographical differences in the surface cause water rigorously self-propel long distances, continuously redistributing film potentially refreshing for re-nucleation. However, dynamic interplay...
The riblet structures of shark skin have a significant biological function for drag reduction, which has been verified. However, it is difficult to fabricate large‐scale bionic surface with high precision and low cost. real micro‐riblets were first measured approximately simplified obtain shark‐skin‐inspired micro‐riblets. Numerical simulations performed explore the drag‐reduction effect surface. According micro‐riblets, nickel mould negative micro‐structures was manufactured by Ultra‐Violet...
Small water droplets or particles located at an oil meniscus typically climb the due to unbalanced capillary forces. Here, we introduce a size-dependent reversal of this meniscus-climbing behavior, where upon cooling underlying substrate, different sizes concurrently ascend and descend meniscus. We show that microscopic Marangoni convection cells within are responsible for phenomenon. While dynamics relatively larger microdroplets still dominated by forces hence meniscus, smaller carried...
For the spread spectrum communication system with ultra-low bit rate, convolutional code and are cascaded to improve performance. Based on high computational complexity of traditional orthogonal codes, uses fast Walsh transform optimization speed up decoding tail biting mechanism transmission efficiency. The results show that error rate (BER) performance is improved as increasing constraint length. When length 10 relative 5, demodulation gain 2.5dB at BER <sup...
Abstract Mg-Mn alloy is welded by friction stir welding technology to manufacture liquid-cooled components in radar equipment. The effect of processes on microstructure and mechanical properties was analyzed. results show that the rotation speed has little structure when it above 1200 rpm. strength increased increase from 900 rpm 1500 highest ultimate tensile about 175 MPa. Most joints brittle fracture during test.
