In-situ morphology studies of the mechanism for solution additive effects on the formation of bulk heterojunction films.

September 29, 2014
Author(s)
Lee J. Richter, Dean M. DeLongchamp, Kang W. Chou, Aram Amassian, A Hexemer, Eric Schaible, Felicia A. Bokel, Sebastian Engmann
The most successful active film morphology in organic photovoltaics is the bulk heterojunction (BHJ). The performance of a BHJ arises from a complex interplay of the spatial organization of the segregated donor and acceptor phases and the local order

May 21, 2014
Author(s)
Sudarsan Rachuri, Sanjay Jain
The general awareness of the need for use of earth’s resources in a sustainable manner has been increasing in recent years. Governments, commercial organizations and individuals have been making efforts to better manage and use available resources

A Framework for Research Inventory of Manufacturing Sustainability Assessment

May 19, 2014
Author(s)
Juyeon Lee, Yung-Tsun T. Lee
There have been many research papers focused on development of guidelines, indicators, metrics, methods, tools, and systems – all related to sustainability performance assessment. However, manufacturing companies have difficulty in finding papers that are

AN INTEGRATED APPROACH TO INFORMATION MODELING FOR THE SUSTAINABLE DESIGN OF PRODUCTS

May 19, 2014
Author(s)
Paul W. Witherell, Douglas Eddy, Ian Grosse, Sundar Krishnamurty, Jack Wileden, Kemper Lewis
The design of more sustainable products can be best accomplished in a tradeoff-based design process that methodically handles conflicting objectives. Such conflicts are often seen between, environmental impact, cost, and product performance. To support

Processes Analytics Formalism for Decision Guidance in Sustainable Manufacturing

May 19, 2014
Author(s)
Alexander Brodsky, Guodong Shao, Frank H. Riddick
This paper introduces National Institute of Standards and Technology (NIST)'s Sustainable Process Analytics Formalism (SPAF) to facilitate the use of simulation and optimization technologies for decision support in sustainable manufacturing. SPAF allows

REQUIREMENTS ANALYSES TO SUPPORT A MATERIAL INFORMATION MODEL FOR SUSTAINABILITY

November 21, 2013
Author(s)
Paul W. Witherell, Arvind Harinder, Katherine C. Morris
Materials, and therefore material selections, influence the sustainable impact of a product from beginning to end-of-life. With improved access to material information, product designers can attain newfound insight into the sustainability implications of

TOWARDS THE SYNTHESIS OF PRODUCT KNOWLEDGE ACROSS THE LIFECYCLE

November 21, 2013
Author(s)
Paul W. Witherell, Boonserm Kulvatunyou, Sudarsan Rachuri
Product lifecycle management is an important aspect of today’s industry, as it serves to facilitate information exchange and management between most, if not all, stages of a product’s existence. As exchanged product information is inevitably subjected to

A Methodology for Handling Standards Terminology for Sustainable Manufacturing

October 30, 2013
Author(s)
Anantha Narayanan Narayanan, David J. Lechevalier, Katherine C. Morris, Sudarsan Rachuri
In order to develop the discipline of sustainable manufacturing, the language of discourse needs to be properly and clearly communicated, for both manufacturers and consumers. As a result a range of information standards that define the needed terminology

Feature Information Model for Disassembly

August 20, 2013
Author(s)
Shaw C. Feng
As sustainability becomes an important issue nowadays, disassembly becomes one of the key processes to turn out-of-service products into new or rebuilt products to save energy and materials. A disassembly process includes many subprocesses, such as

Energy Metrics for Product Assembly Equipment and Processes

August 13, 2013
Author(s)
Shaw C. Feng, FNU Kumaraguru, Christopher U. Brown, Boonserm Kulvatunyou
A key factor deciding the capacity to increase the sustainability of final products is the energy efficiency. The energy embodied in a product is an aggregation of all of the energy embodied in the products' components and subsystems, expended through its

Integration of Energy Information for Product Assembly and Logistics Processes

August 13, 2013
Author(s)
Shaw C. Feng, FNU Kumaraguru, Kincho H. Law, Kyeong Rim Ahn
This paper presents an on-going effort at NIST to model the energy performance in assembly and supply chain processes as a part of a larger sus-tainability improvement goal. Energy performance modeling comprises two dis-tinct metrics like energy

Status and Opportunities to Support Product Category Rules in the U.S.

August 12, 2013
Author(s)
Rita Schenck
Environmental Product Declarations (EPDs) are a kind of ecolabel that discloses the environmental impacts of a product over its life cycle, using the science of life cycle assessment. EPDs hold out the promise of supporting science based decisions in
