Atomic layer deposition (ALD) of aluminum oxide on nonwoven polypropylene and woven cotton fabric materials can be used to transform control fiber surface wetting properties. Infrared analysis shows that ALD produce a uniform coating throughout the matrix, amount controlled by number cycles. Upon oxide, nonwetting hydrophobic fibers transition either metastable or fully hydrophilic state, consistent with well-known Cassie−Baxter Wenzel models roughened surfaces. The observed...
The preparation of microporous and mesoporous metal oxide materials continues to attract considerable attention, because their possible use in chemical separations, catalyst support, sensors, optical electronic devices, energy storage, solar cells. While many methods are known for the synthesis porous materials, researchers continue seek new control pore size distribution macroscale morphology. In this work, we show that sequential vapor infiltration (SVI) can yield shape-controlled...
While metal‐organic frameworks (MOFs) show great potential for gas adsorption and storage, their powder form limits deployment opportunities. Integration of MOFs on polymeric fibrous scaffolds will enable new applications in adsorption, membrane separation, catalysis, toxic sensing. Here, we demonstrate a synthesis route growing materials that achieves high MOF loadings, large surface areas adsorptive capacities. We find nanoscale coating Al 2 O 3 formed by atomic layer deposition (ALD) the...

This work introduces oxidative molecular layer deposition (oMLD) as a chemical route to synthesize highly conductive and conformal poly(3,4-ethylenedioxythiophene) (PEDOT) thin films via sequential vapor exposures of molybdenum(V) chloride (MoCl5, oxidant) ethylene dioxythiophene (EDOT, monomer) precursors. The growth temperature strongly affects PEDOT's crystalline structure electronic conductivity. Films deposited at ∼150 °C exhibit textured structure, with {010} planes aligned parallel...
Three-dimensional nanoscale constructs are finding applications in many emerging fields, including energy generation and storage, advanced water air purification, filtration strategies, as well photocatalytic biochemical separation systems. Progress these important technologies will benefit from improved understanding of fundamental principles underlying nanostructure integration bottom-up growth processes. While previous work has identified hydrothermal synthesis conditions to produce ZnO...
The local heating phenomenon of composite insulator has drawn more and attention gradually. From our analysis, the temperature rise is closely related to moisture in atmospheric environment according research results. Effect on insulators studied this paper. insulators, which have operated power system for a long time been detected heating, new are taken as test samples. increases with relative humidity, while shows no can be detected. sample not relevant core interface between housing...
ZrNiSn-based half-Heusler (HH) alloys are considered very promising thermoelectric (TE) materials at intermediate and high temperatures due to their favorable intrinsic electrical properties, but they also limited by inherent thermal conductivities. Numerous works have focused on reducing conductivities, especially lattice A multielement (Ti, Hf, Nb, V, Sb) multisite alloying strategy for simultaneously improving the properties greatly conductivity of HH TE is reported in this work. The...
Cr(VI) is a common heavy metal pollutants present in the aquatic environment, which possess toxic and carcinogenic properties. In this study, solvothermal reaction was used to prepare porphyrin (TCPP)-modified UiO-66-NH2 (UNT). The UNT integrated adsorption photocatalytics application for dealing with Cr(VI). photocatalytic reduction activities of were investigated under visible light illumination. We found that TCPP doping amount 15 mg (15-UNT) had 10 times higher rate than pristine...
There has been a growing concern over recent years regarding the phenomenon of local heating composite insulators. In this paper, influences humidity, contamination and electric field on temperature dielectric properties field-aged insulators were studied experimentally. Aging silicone rubber (SIR) material weathershed surface, rather than resistive current flow from contamination, was found to be major cause observed by thermography. The aged SIR exhibited strong loss under high localized...
Nanofibers formed by electrospinning provide very large surface areas which can enhance material performance in filtration and product separation. In this work, we explore atomic layer deposition (ALD) as a means to coat protect electrospun nylon-6 nanofibers. Exposing nylon trimethyl aluminum (TMA) during ALD of oxide results significant fiber degradation. Protecting fibers with bilayer ZnO an organic-inorganic hybrid polymer molecular maintains the shape original nanofibers, but chemical...
This paper reviewed the research progress on abnormal temperature rise (ATR) of composite insulator. The ATR insulator can be divided into two types, pointform (PFTR) and bar-form (BFTR). insulators with PFTR only show significant at high relative humidity (RH>70%), locates in area that 20 cm above metal end-fitting. In low environment (RH 70%) (<30%) RH. might reach more than 10 °C was wider, extending from high-voltage end to several sheds units low-voltage side. And GRP core found...
The presence of nanostructured materials in the workplace is bringing attention to importance safe practices for nanomaterial handling. We explored novel fiber containment methods improve handling carbon nanotube (CNT) powders laboratory while simultaneously allowing highly uniform and controlled atomic layer deposition (ALD) coatings on nanotubes, down less than 4 nm some CNT materials. Moreover, procedure yields milligram quantities nanotubes using a conventional viscous flow reactor...
