Nanocellulose membranes could efficiently separate oily wastewater because of their super-hydrophilic and underwater super-oleophobic property nano-porous structure. However, the practical application storage nanocellulose is limited by low water permeation flux easy corrosion bacteria, respectively. Herein, with high permeate antibacterial were fabricated grafting tetrakis(hydroxymethyl) phosp...

Advanced additive manufacturing techniques such as electron beam melting (EBM), can produce highly porous structures that resemble the mechanical properties and structure of native bone. However, for orthopaedic applications, such as joint prostheses or bone substitution, the surface must also be bio-functionalized to promote bone growth. In the current work, EBM porous Ti6Al4V alloy was expose...

a palladium composite membrane was prepared by electroless plating on oxidized porous stainless steel support (ox-pss). hydrogen permeation flux through this composite membrane was measured in the temperature range of 574-674k and the pressure difference of two sides of membrane up to 90kpa. a simplified resistance model was employed to analyze the permeation behavior of hydrogen through pd/ox-...

This study was designed to probe the fabrication of unique silver and gold nano-structures engaging a self-designed chitosan-porous anodic alumina nano-composite as a template. Porous anodic alumina has been manufactured by di-step aluminum anodization in an oxalic acid electrolytic bath. The surface properties of porous anodic alumina were reinforced by chitosan neutralized in sodium hydro...

Nano-textured porous metal materials present unique surface properties due to their enhanced surface energy with potential applications in sensing, molecular separation and catalysis. In this paper, commercial alloy foils, including brass (Cu85Zn15 and Cu70Zn30) and white gold (Au50Ag50) foils have been chemically de-alloyed to form nano-porous thin films. The impact of the initial alloy micro-...

over the past decade, many applications were intended for filtration by membrane technology especially the thin film composite (tfc) membranes. in advanced developments of thin film membranes, an attempt was made to spread a new generation of membranes called thin film nano composite (tfn) membranes. however, in the last generation of tfns, an ultrathin selective film of nanoparticles is coated...

As a key component of lithium-ion batteries (LIBs), separator plays crucial role in the performance and safety LIBs. In this paper, cellulose-based porous membrane modified by nano CaCO3 is prepared conveniently electrospinning. The exhibits rich fibrous networks uniform distribution nanoparticles. Strengthened CaCO3, tensile strength cellulose elevates from 4.7 ± 0.4 MPa to 7.7 0.7 MPa. Beside...

The extraction of renewable energy resources particularly from earth abundant materials has always been a matter of significance in industrial products. Herein, we report a novel simultaneous extraction of nano-silicon with activated carbons (nano-Si@ACs) from rice husk (RH) by chemical activation method. As-extracted nano-Si@ACs is then used as an energy harvesting materials in counter electro...

Gold nanoparticles were synthesized using agarose as a reducing agent, which gelled to support the gold nanoparticles, then readily functioned as a template to produce a porous, evenly-distributed Au/TiO(2) nano-hybrid.

We present the first use of digital microfluidic techniques to perform on-chip solid phase extraction (SPE). The material used for SPE was a porous polymer monolith with 12-carbon functionality (C12 PPM) which was photopolymerized on-chip and used to desalt a peptide sample prior to nano-electrospray ionization mass spectrometric analysis (nano-ESI-MS). We anticipate this technique may be usefu...
