New UV Technology for Point-of-Use Water Disinfection

Bilenko O., Bilenko Y., Shturm I., Bilenko O., Bilenko Y., Shatalov M., Gaska R., Sensor Electronic Technology, Inc., US

We will report on a record performance of an all-LED point-of-use water disinfection system that utilizes our deep UV LED lamps with peak emission wavelengths in the range from 270 nm to 280 nm. Results [...]

Innovative Cost-effective Pre-treatment for Desalination

Lean M.H., Seo J., Kole A., Volkel A.R., Chang N., Hsieh B., Melde K., Palo Alto Research Center, US

This paper describes an innovative technology to pre-treat feed water for desalination. An inline coagulation-flocculation-separation (CFS) system is detailed that does not require filtration or sedimentation. Advantages include: scalability, modularity, rapid processing, low energy, and [...]

Green Building visions in historical Arab cities, case study of Al-Jazirah Al-Hamrah-Northern UAE

Al-Farraj A., UAE University, AE

With the oil discovery during 1960s, and the initiation of the UAE in 1972, most of old house and building has been replaced with modern building. Al-Jazirah Al-Hamrah in the Northern UAE, the only historical [...]

Recovery of High Quality Aggregate from Concrete Waste using Pulsed Power Technology

I’izasa S., Shigeishi M., Namihira T., Kumamoto University, JP

In Japan, the most of waste concrete scraps have been eused as roadbed materials and the recycling ratio of waste concrete scraps has been kept over 95 % from 2000. However, it is expected that [...]

Clean Technology Requires a Systems Approach

Kralj D., ART-K, BusinessConsulting, SI

The challenge of addressing climate change in the context of moving society towards the environmental, economic and social goals of sustainability requires radical innovation of cleaner technologies and processes which meet individual and social needs [...]

Efficiency’s Last Frontier: Reflective Building Surfaces

Wiig H.C., State of Hawaii Energy Office, US

Lawrence Berkeley Laboratory scientists hold that if the world’s urban areas were highly reflective, global warming would be delayed by eleven years. However, America’s building energy codes do not cite reflective surfaces as key paths [...]

Mechanical Properties of PLA-Jute Composites by Using Natural Rubber and Epoxidized Natural Rubber as Impact Modifiers : Effect of Molding Technique

Ruksakulpiwat Y., Tonimit P., Kluengsamrong J., Suranaree University of Technology, TH

Jute fiber was used as a reinforcing fiber in poly (lactic acid) (PLA) composites. Natural rubber (NR) and epoxidized natural rubber (ENR) are used as impact modifiers of jute-PLA composite. The composite specimens were prepared [...]

Nanobrush Structured Oligo(epsilon-caprolactone) as a Novel Plasticizer for the Manufacture of Eco-friendly Poly(vinyl chloride)

Choi W.H., Kwak S-Y, Seoul National University, KR

Phthalates such as DEHP are the most commonly used plasticizers in flexible PVC. According to the information recently reported, the phthalates still hold almost 90% of the world’s plasticizer market. There have been, however, many [...]

The study of using glycidyl methacrylate grafted natural rubber as an impact modifier of polylactic acid

Juntuek P., Ruksakulpiwat C., Ruksakulpiwat Y., humsamrong P., Ruksakulpiwat C., Ruksakulpiwat Y., Suranaree University of Technology, TH

Glycidyl methacrylate (GMA) was grafted onto natural rubber (NR) using emulsion polymerization method and using cumene hydroperoxide (CHP) and tetraethylenepentamine (TEPA) as an initiator. Glycidyl methacrylate grafted natural rubber (NR-g-GMA) were melt blended with polylactic [...]
