Passive Solar Design of Buildings – a Case Study

Kumar S., Bansal M., GZS College of Engineering & Technology, IN

Passive solar technologies are means of using sunlight for useful energy without use of active mechanical systems, as contrasted to active solar techniques. Such technologies convert sunlight into usable heat in the form of water, [...]

Green Building a Step Toward Energy Conservation: An Overview

Bansal M., Giani Zail Singh College of Engineering & Technology, Bathinda, Punjab, INDIA, IN

This paper highlights the situations for better understanding of the concept of green building for significant environmental, economic and social benefits regarding energy conservation. Commercial building or non-green building are responsible for usage of considerable [...]

Maintaining a Stable Engineered Nanomaterials Process through Material Characterization during the Nano Product Life Cycle

Salamon A.W., PerkinElmer Corporation, US

Nanomaterial synthesis, end-product formulation, and nanomaterials’ wide range of applications are outpacing regulations and standard methods. No matter what your nano-end-product application may be, from food to pharmaceuticals to petrochemicals, there are seven key characteristics [...]

The Effect of Nanoparticles on Bacteriophage Infection

Nickel A.L., Pedulla M.L., Kasinath R.K., Montana Tech, US

We present the results of our recent findings that the introduction of apatite nanoparticles (~10 nm) in a classical phage-bacteria infection scenario increases the efficacy of the phage infection as investigated through plaque formation. The [...]

Exposure modeling of engineered nanoparticle

Som C., Mueller N.C., Sonderer T., Gottschalk F., Scholz R., Nowack B., Empa Materials Science and Technology, CH

An elementary step towards a quantitative assessment of the risks of new compounds to the environment is to calculate their predicted environmental concentrations (PEC). The aim of this study was to use a life-cycle perspective [...]

Integrating the Triple Bottom Line of Sustainability with Life Cycle Environmental Assessments for Military Non-Lethal Technologies

Saulters O., Green R., Kansas State University, US

The Non-lethal Environmental Evaluation and Remediation Consortium, comprised of M2 Technologies, Kansas State University, and CABEM Technologies, performs environmental research, training, assessment, and product development for the Department of Defense. The NEER Consortium addresses complex [...]

Environmental CleanTechnology

Sapkal R.S., Sapkal V.S., Sapkal R.S., Sapkal V.S., Shinde G.B., Pune University, IN

“Green technology” or Clean technology is the application of the environmental sciences to conserve the natural environment and resources, and by curbing the negative impacts of human involvement. Our innovations have helped move the world [...]

So You Want to Replace Your PVC

Gibb S.E., Beckman E.J., University of Pittsburgh, US

This paper looks at product design in the context of PVC pipe replacement. A three metric system is used assessing the functionality, economics, and environmental aspects of a product to truly create greener products that [...]

Regulation of Nanotechnology in the Environment

Lehrenbaum W.U., Zarghamee R., Leopold Jr. C., Pillsbury Winthrop Shaw Pittman LLP, US

In this paper we examine the current state and likely future path of nanotechnology regulation by the U.S. Environmental Protection Agency (“EPA” or “the Agency”). We also explore a number of initiatives that have arisen [...]

A Framework for Responsible Nanotechnology

Walsh S., Medley T., Environmental Defense, US

Environmental Defense, an environmental advocacy organization, and DuPont, a science company, have developed a comprehensive, practical, and flexible framework for evaluating and addressing the potential risks of nanoscale materials. The draft framework is available for [...]
