The overhead aluminum conductors are prone to corrosion, especially in areas with marine climates, which interferes with the safe operation of the power system. Herein, slippery liquid infused porous surface (SLIPS) conductors were successfully prepared on pure aluminum (Bare) conductors by anodizing and infusion of silicone oil. The corrosion resistance of the conductors during 30 days of salt spray corrosion and 7 days of energized conditions was studied. The results indicated that the corrosion of the Bare and anodic aluminum oxide (AAO) conductors was more severe under energized (alternating current (AC) and direct current (DC)) conditions. The exacerbation of corrosion by DC energization was remarkably higher than that of AC energization. The AAO conductor showed better corrosion resistance than the Bare conductor, which was attributed to the porous alumina retarding the medium intrusion. Due to the barrier effect provided by the lubricant layer, the SLIPS conductor always presented excellent corrosion resistance than the Bare and AAO conductors. In addition, the mechanical and electrical properties of the SLIPS conductor were comparable to the Bare conductor and could satisfy the basic requirements for practical applications. The prepared SLIPS conductors offer great application prospects for the corrosion protection of aluminum conductors.

Emulsified oil leakage onto the bulk water surface causes severe issues on global ecology and health. Developing efficient, rapid, and universal separation methods of emulsions has been a significant topic in scientific studies. However, a contactless and additive-free strategy to achieve continuous floating emulsion separation and oil collection remains to be discovered. Herein, a universal contactless demulsification, transportation, and collection method to dispose floating emulsions by ionic wind, which contains active charged particles generated by corona discharge is reported. The splash-like demulsification process of floating emulsions is attributed to the rupture of water film enveloped on oil droplet surface, simultaneously and respectively. The evidence of this process recorded by a high-speed camera with 20 000 fps has a referential significance for other works. This study may clean up universal floating emulsions discharged on water in real situations such as oil stations, chemical plants, and restaurants, and furthermore increase the potential of remote control in liquid dynamics by corona discharge.

Flush toilets waste a significant amount of water every day due to the unavoidable adhesions between human waste and the toilet surfaces. Super-slippery surfaces can repel complex fluids and various viscoelastic solids, however, are easily broken by mechanical abrasions. Herein, the fabrication of an abrasion-resistant super-slippery flush toilet (ARSFT) is reported using a selective laser sintering 3D printing technology. Unlike traditional super-slippery surfaces with limited thicknesses which can be easily worn away, the powder-sintered strategy endows the ARSFT not only with a self-supporting 3D complex shape but also with a porous structure that can accommodate considerable lubricants for an abrasion-resistant super-slippery property. As a result, the as-prepared ARSFT remains clean after contacting with various liquids such as milk, yogurt, highly sticky honey, and starch gel mixed congee, demonstrating excellent repellence to complex fluids. Besides liquids, the ARSFT exhibits a high resistance to sticky synthetic feces. Notably, even after being abraded to 1,000 cycles of abrasion using sandpaper, the ARSFT maintains its record-breaking super-slippery capability. The concept of the 3D-printed object with a superior abrasion-resistant slippery ability will improve the development of super-slippery materials and further save water consumption in the human society.

It is difficult for any marine engineering equipment to avoid the impact of biofouling. Especially, for engineering equipment made of titanium with a high biocompatibility, biofouling is a thorny problem. The outstanding anti-biofouling properties of the slippery liquid-infused porous surfaces (SLIPSs) and the grafted polydimethylsiloxane (gPDMS) brush surfaces have attracted the attention of researchers. However, the durability and stability of the conventional SLIPSs and the wear resistance of gPDMS are insufficient and should be improved. In this work, PDMS molecule brushes were grafted onto a micro-arc oxidized porous surface infused with a lubricant (silicone oil) to develop a grafted SLIPS (gSLIPS) on a titanium alloy (TA2). The gPDMS molecule brushes have a stronger chemical affinity with silicone oil, which can preserve more lubricants to enhance the durability and stability of the SLIPS. Simultaneously, the infused lubricant in the micro-arc oxidized porous surface can improve the wear resistance of the grafted molecule brushes. Besides, the molecule brushes can further isolate the vulnerable titanium substrate from the biofouling microorganisms. By combining the advantages of the SLIPS and gPDMS, the gSLIPS has excellent stability, durability, and mechanical robustness. The gSLIPS possesses a better biofouling resistance than TA2 and gPDMS. For example, the coverage of Chlorella on the gSLIPS is 0.067% ± 0.022% after being immersed for 14 days, which reduces by 98.8 and 95.6% compared with those on TA2 and gPDMS, respectively. In addition, the gSLIPS also has excellent anti-protein property. Therefore, this method will help develop a more stable, durable, and mechanically robust super-slippery coating with excellent anti-biofouling performance, which has great potential for the extensive titanium applications in marine engineering.

Gallic acid-based epoxy resin monomer was synthesized by the natural extract of gallnut for the efficient dispersion of graphene in epoxy resin. The graphene zinc-rich anticorrosion coatings were further prepared on the basis of the graphene / gallic acid-based epoxy resin monomer dispersion system. Electrochemical experiments and spectral characterization were carried out to study the effect of graphene on zinc-rich coatings and its mechanism. Experiments showed that graphene enhanced the cathodic protection currents of the zinc-rich coatings and prolonged the cathodic protection time. Simultaneously, graphene slowed down the penetration of corrosive media into the coatings. The conductivity of graphene improved electrical contact between zinc particles as well as zinc and iron, and transformed un-activated zinc particles into activated zinc particles. The dispersed and layered structure of the graphene extended the permeation path of the corrosive medium, which resulted in reduced permeation rate and decreased water content of the coatings. It was demonstrated by the tracking of zinc corrosion products by micro-area Raman spectroscopy.

Respiratory viruses have long been a major cause of a global pandemic, emphasizing the urgent need for high-sensitivity diagnostic tools. Typical PCR technology can only determine the type of virus in the sample, which is unable to detect different variants of the same virus without costly and time-consuming gene sequencing. Here, we introduce a simple, fully enclosed, and highly integrated microfluidic system based on CRISPR/Cas12a and isothermal amplification techniques (LOC-CRISPR) that can specifically identify multiple common respiratory viruses and their variants. The LOC-CRISPR chip integrates viral nucleic acid extraction, recombinant polymerase amplification, and CRISPR/Cas12a cleavage reaction-based detection, contamination-free detection. In addition, the LOC-CRISPR chip was designed for multiplexed detection (two-sample input and ten-result outputs), which can not only detect the presence of SARS-CoV-2, H 1 N 1 , H 3 N 2 , IVB and HRSV but also differentiate the BA.1, BA.2, and BA.5 variants of SARS-COV-2. For clinical validation, the LOC-CRISPR chip was used to analyze 50 nasopharyngeal swab samples (44 positive and 6 negative) and achieved excellent sensitivity (97.8%) and specificity (100%). This innovative LOC-CRISPR system has the ability to quickly, sensitively, and accurately detect multiple target nucleic acid sequences with single-base mutations, which will further improve the rapid identification and traceability of respiratory viruses infectious diseases.

The icing of transmission conductor seriously threatens the safe operation of power grids. Slippery lubricant-infused porous surface (SLIPS) has shown great potential for anti-icing applications. However, aluminum stranded conductors have complex surfaces, and the current SLIPSs are almost prepared and studied on small flat plates. Herein, the construction of SLIPS on the conductor was realized through anodic oxidation and the anti-icing mechanism of the slippery conductor was studied. Compared to the untreated conductor, the SLIPS-conductor reduces the icing weight by 77% in the glaze icing test and shows very low ice-adhesion strength (7.0 kPa). The excellent anti-icing performance of the slippery conductor is attributed to the droplet impact dynamics, icing delay, and lubricant stability. The dynamic behavior of water droplets is most affected by the complex shape of the conductor surface. Specifically, the impact of the droplet on the conductor surface is asymmetric and the droplet can slide along the depression in low-temperature and high-humidity environments. The stable lubricant of SLIPS increases both the nucleation energy barriers and the heat transfer resistance, which greatly delays the freezing time of droplets. Besides, the nanoporous substrate, the compatibility of the substrate with the lubricant, and the lubricant characteristics contribute to the lubricant stability. This work provides theoretical and experimental guidance on anti-icing strategies for transmission lines.

The rigid polyurethane foam (RPUF) with excellent flame retardancy, high compressive strength and good thermal insulation performance is of great importance to its widely application, especially the application in high-rise building exterior wall materials. In this work, two kinds of flame-retarding polyols (DADP and APDP) containing phosphorus and nitrogen elements were prepared via a simple salinization reaction and reacted into RPUF chains. When only 15 wt% of APDP was incorporated, the material passed the UL-94 V-0 rating with a limiting oxygen index (LOI) of 24.5% while 20 wt% of DADP incorporated to realize the same flame-retarding effect. For the RPUF/APDP 15 , the peak heat release rate (PHRR) decreased by 28.2% comparing to the neat RPUF and the fire growth rate (FIGRA) was the lowest 8.3, indicating the lowest flame spread speed among all the flame-retarding RPUF. The compressive strength of the RPUF/APDP 15 material increased by 41.8% comparing to that of neat RPUF, mainly causing by the good compatibility and the enhancement of hardness of polyurethane via the benzene ring. Moreover, it was concluded that the gas-phase mechanism dominated in enhancing the flame-retarding effect for the RPUF material, and the APDP showed a higher flame-retarding effect with a higher content of phosphorus and nitrogen elements than that of DADP.

Micro gas chromatography (μGC) using microfabricated silicon columns has been developed in response to the requirement for portable on-site gas analysis. Although different stationary phases have been developed, repeatable and reliable surface coatings in these rather small microcolumns remains a challenge. Herein, a new stationary phase coating strategy using magnetic beads (MBs) as carriers for micro column is presented. MBs modified with organopolysiloxane (MBs@OV-1) and a metal organic framework (MBs@HKUST-1) are deposited in on-chip microcolumns assisted with a magnetic field with an optimized modification process. MBs@OV-1 column showed a minimum HETP of 0.074 cm (1351 plates/m) of 62 cm/s. Mixtures of volatile organic compounds are successfully separated using MBs carried stationary phase which demonstrates that this technique has good chromatographic column efficiency. This method not only provides a novel coating process, washing and characterization of the stationary phases but also establishes a straightforward strategy for testing new absorbent materials for μGC systems.

Tooth extraction will leave a wound that may cause blood leakage, and the application of liquid-absorbing hemostatic cotton pressed on the wound can play the effect of pressure to halt bleeding. Unfortunately, the loose structure of the dental absorbent hemostatic cotton causes local slag to fall. Cotton fiber will impede wound heading and possibly drop into the throat and esophagus, thus impacting the life and health of the patient. Therefore, it is of great significance to prepare a material with toughness and high liquid absorption. The polyurethane foams (PUFs) with different chain extension coefficients synthesized from polyether polyol and diphenylmethane diisocyanate (MDI) with water as the blowing agent have excellent toughness and liquid-absorbing properties with potential applications. The hydrophilic polyethylene glycol (PEG) is introduced into the polyurethane chain segment to form a synergistic effect with the three-dimensional foam network structure to absorb more wound exudate. The hydrophobic PUFs can be applied to wounds with less exudate and the hydrophilic PUFs can be applied to chronic wounds with more exudate. The porous structure gives the PUF a strong loading capacity and promotes the wound-healing effect. The PUFs exhibit good liquid absorption/retention performance in both 0.9 wt% NaCl solution and DI water, especially PUF-1.10 has an ultimate DI water absorbency of nearly 840%. According to the performance, comparison of the current market commonly used dental absorbent hemostatic cotton; PUF-1.10 is considered a promising candidate for replacing traditional dental commercial absorbent hemostatic slag-fall cotton in liquid absorption/retention and mechanical properties.

Polylactic acid (PLA) has great potential to replace traditional petroleum-based polymers, especially in membrane production, due to its biocompatibility, degradability, and renewability. However, there are rare reports of superhydrophobic and breathable PLA membranes. In this work, a multifunctional PDMS/SiO 2 @PLA membrane with superhydrophobicity and breathability was prepared by coaxial electrospinning method to coat the surface of PLA fiber with a thin layer of biocompatible polydimethylsiloxane (PDMS) and nano-silica particles. The prepared membrane has a water contact angle (WCA) of 151.8 ± 1.3° and a water sliding angle (WSA) of 5.7 ± 0.3°. Thanks to its superhydrophobicity, it can support a water column of 195 cm. The membrane has excellent breathability that its water vapor transmission rate is ~14.7 kg·m −2 ·24 h −1 . Moreover, the freezing time of the membrane is 2.25 times longer than that of the original PLA membrane. In addition, it has an oil-water separation efficiency of 99.9 % and a flux of ~12,300 L·m −2 ·h −1 . The overall performance of this multi-functional PDMS/SiO 2 @PLA membrane is one of the best among the fluorine-free electrospun membranes.

Carbon capture and utilization (CCU) of microorganisms is widely expected to provide fresh insight into oil wastewater treatment due to green and sustainable processing, and the constant pursuit of high efficiency and sufficient waste utilization to combat climate change calls for the development of advanced engineering microbiology. Here, we explored and proposed a brand-new method to improve CCU in oil wastewater treatment using modular microbiota systems (MMSs). The modular assembly of microorganisms developed in this study allowed for efficient synergy and the design of carbon exchange routes on demand. The microfluidic-assisted assembly of MMSs achieved high specific surface area and good monodispersity during treatment. And the functionalized biomaterials immobilized MMSs possess adsorption to the oil pollutant and settleability for bioresources harvesting. The practical treatment process has validated feasibility and performance of this strategy. The MMSs achieved a breakthrough seven-day crude treatment efficiency (10 g/L) of 95.8 %, and the carbon utilization (lipid accumulation) of MMSs was elevated from 0.1079 g/L to 0.2081 g/L as compared to normal algae culture treatment. The MMSs showed reliable and efficient CCU in different environmental tests. Moreover, the reconfigurable modular microbiota assembly endows this method with superior scalability, which should enable diverse water treatment applications in global settings and provide a potential path for on-demand waste conversion to bioenergy.
