Wet and dry? The ability to control wettability of a solid surface is essential in many fields. A simple effective "template rolling press" method for preparing large-area patterned surfaces with controlled wetting properties (see picture) on the nanometer scale demonstrated. It believed that reorientation polymer molecules occurs when heated compressed into nanopore template.
A unique hybrid nanostructure of MoS<sub>2</sub>@ACNTs is designed and fabricated as an anode material for sodium-ion batteries. With advantages its constituents architecture, the MoS<sub>2</sub>@ACNT electrode capable exhibiting a high discharge capacity 461 mA h g<sup>−1</sup>even over 150 cycles at current density 500 g<sup>−1</sup>.
In this paper, we present a simple, yet novel, method, utilizing scraping to obtain continuous rough microstructures over large areas, leading tunable wettability conversion from hydrophilicity superhydrophobicity on polymer surfaces. A series of polymers ranging hydrophobic hydrophilic were used, and found that the these surfaces could be modified by process, irrespective their hydrophobicity or hydrophilicity. More importantly, those with contact angle 65° 90° smooth also exhibit enhanced...
It still remains very challenging to design proper heterostructures enhance the electrochemical performance of transition metal oxide-based anode materials for lithium-ion batteries. Here, we synthesized NiCoO2 nanosheets@SnO2 layer heterostructure supported by amorphous carbon nanotubes (ACNTs) which is derived from polymeric (PNTs) a stepwise method. The inner SnO2 not only provides considerable capacity contribution but also produces extra Li2O promote charge process and thus results in...
Abstract Spherical AlN powders with micrometer size have attracted great attention owing to their good fluidity and dispersity. However, the industrial preparation methods usually require high temperature long soaking time, which lead cost limit wide application of products. Herein, nearly spherical particles average 2.5 µm were successfully synthesized via an in-situ combustion synthesis method. The effect N 2 pressure, NH 4 Cl content, Al particle on reaction procedure, phase composition,...
The indicative ability of a gas indicator for the spontaneous combustion coal is affected by secondary oxidation oxidized coal, from old goafs, entering new goaf through air leakages. This phenomenon can affect accuracy early warning systems regarding in goaf. In this research, three kinds were selected to carry out simulation experiment which temperature-programmed experimental device was used analyze behavior index towards raw and latter at 70 °C, 90 130 150 °C. results show that chain...
Epithelial-mesenchymal transition (EMT) is a critical early event in tumorigenesis. The contribution of heparan sulfate (HS) to EMT has not been fully elucidated. HS D-glucosaminyl 3-O-sulfotransferase-3B1 (3-OST-3B1) participates the final step fine structure biosynthesis, whose involvement cancer yet be determined. This study demonstrated that following treatment with trichostatin-A, histone deacetylase inhibitor, 3-OST-3B1 gene expression was activated pancreatic cell line, PANC-1. By...
LiFePO4 is a promising cathode material for lithium-ion batteries due to its excellent rate capability and superior safety. However, relatively low energy density makes the research efforts towards another olivine structure LiMnPO4, which exhibits higher operating voltage. Nevertheless, LiMnPO4 does not show remarkable electrochemical performance attributing from electronic/ionic conductivity. To solve problems, facile solvothermal method used successfully synthetise LiMn1-xFexPO4/C with...
Obtaining large plastic deformation in polycrystalline van der Waals (vdW) materials is challenging. Achieving such especially difficult graphite because it highly anisotropic. The development of sugar-derived isotropic nanostructured (SINPG) discussed herein. structure this material preserves the high in-plane rigidity and out-of-plane flexibility graphene layers enables prominent plasticity by activating rotation nanoscale (5-10 nm) grains. Thus, micrometer-sized SINPG samples demonstrate...
Internal resonance between different vibration modes in micromechanical devices has been widely studied due to its promising application prospects microelectromechanical systems (MEMS) resonators and oscillators.
