polyacrylonitrile (pan) membranes with nano-porous surface and high hydrophilicity were fabricated by addition of polyoxyethylene (40) nonylphenyl ether (igepal) as an additive in the casting solution. the membranes were prepared from pan/igepal/1-methyl-2-pyrrolidone (nmp) via phase inversion induced by immersion precipitation technique. pure water was used as coagulation medium. the effects o...

A new method is developed to enhance the gas separation properties of mixed matrix membranes (MMMs) by interior modification of an inorganic nano-porous particle. Ship-in-a-bottle (SIB), as a novel synthesis strategy, is considered to encapsulate a polyaza macrocyclic Ag-ligand complex into the zeolite Y, which is resulted in a new host-guest nano-composite. It is consequently incorporated into...

⎯ A new micromachining method to fabricate wafer scale, atomically smooth nano-membranes is described. The delicate membrane is supported on a robust silicon microsieve fabricated by plasma etching. The supporting sieve is micromachined independently of the nano-membrane, which is later fusion bonded to it. The transferred thin-film membrane can be dense, porous or perforated according to the a...

A novel TiO(2) nano-thorn membrane was assembled for concurrent filtration and photocatalytic oxidization to remove pollutants in water. This membrane has hierarchical porous and multifunctional properties, which provide these advantages: (1) producing water with high quality; (2) increasing water flux; and (3) eliminating membrane fouling.

in this work, a simple and effective way to modify the support surface is developed and a nanostructure ceramic support to facilitate deposition of a defect-free overlying micro and meso (nano) porous membrane is obtained. to achieve high performance nanocomposite membranes, average pore size of outer surface of support was reduced by dip-coating in submicron and nano α-alumina slurries. in thi...

Here, we reported a strategy of using an eggshell membrane to produce hierarchically porous carbon as low-cost substrate for synthesizing nano-nickel oxide catalyst (C@NiO), which can effective...

We investigate the PL characteristics of the equivalent-size controlled Si-QDs by employing the nano-porous AAO membrane as the template for growing Si-rich SiOx nano-rods to achieve the spatially confined synthesis of Si-QD. The ultra-bright PL can be emitted from the SiOx nano-rod in nano-porous AAO membrane. In addition, we preliminarily demonstrate the in-situ high-temperature synthesis of ...
