Effects of membrane pore morphology on fouling behavior of polymeric micro-fabricated membrane during crossflow micro-filtration

Warkiani M.E., Gong H.Q., Fane A.G., Wicaksana F., Nanyang Technological University, SG

Membrane pore morphology can have a significant effect on the rate of flux decline where the dominant fouling mechanism is pore blockage and cake formation. Commercial micro-filters cannot be used effectively for this purpose because [...]

Microwave assisted synthesis of CaO nanoparticles and use in waste water treatment

Roy A., Bhattacharya J., Indian Institute of Technology, Kharagpur, IN

Clean water (i.e., water that is free of toxic chemicals and pathogens) is essential to human health. Advances in nanoscale science and engineering are providing unprecedented opportunities to develop more cost effective and environmentally acceptable [...]

Near-field infrared nanoscopy of phonon resonant silica and silica-coated goldnoparticles

Abate Y., California State University Long Beach, US

Single silica capped and uncapped gold nanoparticles are imaged using apertureless near-field optical microscopy (ANSOM) in the visible (λ=632 nm) and infrared frequencies (λ=10.7 µm). Identification of capped and uncapped particles with nanoscale spatial resolution [...]

ALD for sustainable future – building a cleaner world from sub-nanometer level

Toivola M., Pilvi T., Picosun Oy, FI

Atomic Layer Deposition (ALD) offers a superior way to coat highly conformal, uniform, pinhole and defect free thin films on even the most challenging nanoscale architectures. The technique is already widely in use in e.g. [...]

Boehmite nanometric with high surface area synthesized from a microwaves hydrothermal method

Quirino M.R., Oliveira M.J.C., Keyson D., Gama L., Bosco J., Federal University of Paraíba, BR

As the crystallization kinetics is enhanced by the introduction of the microwave hydrothermal method, the arm of this work was to produce and characterize boehmite by microwave-assisted hydrothermal. Boehmite nanostructure were synthesized by a hydrothermal [...]

Improve Environmental and Economic Performance with Streamlined Life Cycle Assessment (SLCA)

Shatkin J.A., Larsen W., CLF Ventures, Inc., US

Many new technologies offer significant improvements in environmental performance over existing approaches. Typically, there is some uncertainty about the health or environmental impacts, positive or negative, of new technologies, which can adversely affect their introduction [...]

Octadecylphosphonic acid Langmuir-Blodgett films and their modification by hyperthermal hydrogen projectile

Dey R., The university of waterloo, CA

We report on surface modification with hyperthermal hydrogen induced cross-linking (HHIC) technology on uniform and well-ordered octadecylphosphonic acid (OPA) Langmuir-Blodgett (LB) films on several surfaces, and on surface characterizations of its properties. The hyperthermal hydrogen [...]

Photocatalytic Activity of Coated PET Fabrics with Synthesised Nano TiO2

Elahi A., Khajavi R., Torkian L., Textile Engineering, IR

Different concentration of TiO2 sols (10-40% g/l) synthesized by titanium tetra isopropoxide (TTIP). PET fabric dipped in prepared sols and sol-gel process accomplished at low temperature. Particle size of synthesised Nano TiO2 determined by particle [...]

The Characteristics and Photocatalytic Activity of Visible Light Driven N-doped TiO2

Hsu H-J, Lin Y-H, Lin Y.-T., Lin Y-H, Lin Y.-T., National Chung Hsing University, TW

In the recent decades, titanium dioxide (TiO2) nano-material was received widely attention because of its good chemical stability, low-toxicity, self-cleaning, anti-bacteria and deodorant. However, its photocatalytic activity was limited only by ultraviolte (UV) light irradiation [...]
