Flexible Mushroom-Like Cross-Scale Surface with Extreme Pressure Resistance for Telecommunication Lines Anti-Icing/Deicing.

Ice accretion caused by freezing rain or snowstorms is a common phenomenon in cold climates that seriously threatens the safety and reliability of telecommunication lines and other overhead networks. Various anti-icing strategies have been demonstrated through surface engineering to delay ice formation. However, existing anti-icing surfaces still encounter several challenges; for example, surfaces are prone to ice-pinning formation due to the impact of supercooled droplets, which leads to a loss of anti-icing effectiveness.

Micro/Nano Hierarchical Crater-Like Structure Surface With Mechanical Durability and Low-Adhesion for Anti-Icing/Deicing.

Superhydrophobic surfaces have attracted significant attention for their ability to prevent ice formation and facilitate deicing without requiring external energy. However, these surfaces are often vulnerable to damage from external forces, leading to functional failure due to poor mechanical stability, which limits their widespread use. Drawing inspiration from the hierarchical groove of rose petals and the micropapillae of lotus leaves, a simple laser-based method is proposed to create a superhydrophobic surface with a micro/nano hierarchical crater-like structure (HCLS).

Femtosecond laser composite manufactured double-bionic micro-nano structure for efficient photothermal anti-icing/deicing.

The solar anti-icing/deicing (SADI) strategy represents an environmentally friendly approach for removing ice efficiently. However, the extensive use of photothermal materials could negatively impact financial performance. Therefore, enhancing light utilization efficiency, especially by optimizing the design of a structure with a low content of photothermal materials, has rapidly become a focal point of research.

Spontaneous Separation of Immiscible Organic Droplets on Asymmetric Wedge Channels with Hierarchical Microchannels.

Spontaneous separation of immiscible organic droplets has substantial research implications for environmental protection and resource regeneration. Compared to the widely explored separation of oil-water mixtures, there are fewer reports on separating mixed organic droplets on open surfaces due to the low surface tension differences. Efficient separation of mixed organic liquids by exploiting the rapid spontaneous transport of droplets on open surfaces remains a challenge.

Selection of the cutoff value of the tuberculin skin test for diagnosing students who need preventive treatment: A school-based cross-sectional study.

Objective: Tuberculosis outbreaks in schools are common in China. This study aimed to introduce and evaluate a new screening process to help control outbreaks.

Methods: Screening information of students in three schools with tuberculosis outbreaks was collected.

Effects of whey protein on the in vitro digestibility and physicochemical properties of potato starch.

The aim of this study was to examine the effect of whey protein isolate (WPI) on the digestibility and physicochemical properties of potato starch (PS) after heat treatment. WPI reduced the digestibility of PS and increased the order and aggregation structure of gelatinized PS. Examination of the rheological properties of the PS-WPI mixed system before and after adding different chemicals (sodium chloride, urea, and sodium dodecyl sulfate) indicated an involvement of hydrogen bonds and hydrophobic interactions in the PS-WPI gelatinization system.

[Isolation of the Culex flavivirus from mosquitoes in Liaoning Province, China].

A flavivirus, Culex flavivirus, was first isolated from Chinese mosquitoes with high sequences similarities to those of flaviviruses found in America and Japan. In this study, a total of 48 pools of field-collected mosquitoes were sampled from Dandong of Liaoning Province, China during July to September of 2011. Six isolated viruses showing cytopathic effect (CPE) in C6/C36 cells were tested by reverse transcription polymerase chain reaction(RT-PCR)using Flavivirus genus--specific primers and Culex flavivirus-specific primers and the positive PCR-product was sequenced and compared with the sequences of 10 isolates from GenBank.
