1. TITLE European Parliament May Soften Stance on REACH
AUTHOR Scott, Alex; Young, Ian
SOURCE Chemical Week, September 15, 2004, vol. 166, no. 30, p. 8
ABSTRACT Karl-Heinz Florenz, newly appointed chairman of the European Parliament's environment committee, says the proposed European chemicals testing program must make sure it takes into consideration the policies of nations outside of the EU, including the US. The European Council of Ministers and Parliament are jointly responsible for drawing up European Union environmental legislation including Registration, Evaluation, and Authorisation of Chemicals Program (REACH). Florenz says that there is a requirement to balance out the needs of the environment with those of industry, and it is important that REACH is in harmony with other major trading partners. The move effectively means REACH would have to be watered down in line with US demands.
2. TITLE Dioxin Revisited: Developments Since the 1997 IARC Classification of Dioxin as a Human Carcinogen
AUTHOR Steenland, Kyle, et al.
SOURCE Environmental Health Perspectives, September 2004, vol. 112, no. 13, pp. 1265-1268
ABSTRACT In 1997 the International Agency for Research on Cancer (IARC) classified 2,3,7,8-tetra-chlorodibenzo-p-dioxin (TCDD; the most potent dioxin congener) as a group 1 carcinogen based on limited evidence in humans, sufficient evidence in experimental animals, and extensive mechanistic information indicating the TCDD acts through a mechanism involving the aryl hydrocarbon receptor (AhR), which is present in both humans and animals. The judgment of limited evidence in humans was based primarily on an elevation of all cancers combined in four industrial cohorts. The group 1 classification has been somewhat controversial and has been challenged in the literature in recent years. In this article we review the epidemiologic and mechanistic evidence that has emerged since 1997. New epidemiologic evidence consists primarily of positive exposure-response analyses in several of the industrial cohorts, as well as evidence regarding how the AhR functions in mediating the carcinogenic response to TCDD. The new evidence generally supports the 1997 IARC classification.
3. TITLE Organic, Low-Phenol Stabilizers for Flexible PVC, Fittings
SOURCE Modern Plastics, September 2004, vol. 81, no. 9, p. 109
ABSTRACT An organic-based stabilizer system, OBS, can be used as a lead replacement in pipes, fittings, and many flexible PVC applications such as floor coverings and automotive interiors. OBS, first introduced in Europe, in now offered worldwide. Also being shown at the fair is a new line of low-phenol to phenol-free liquid mixed-metal stabilizers. These are designed to eliminate or reduce phenol content in such applications as vinyl wall and floor coverings and furniture. The material stabilizes without any loss of its stabilizer performance. These products are based on either calcium zinc or barium zinc. Crompton Vinyl Additives Europe, Lampertheim, Germany; www.cromptoncorp.com.
4. TITLE Water and Energy Management for Textile Dyers and Finishers
AUTHOR Grizzle, Tom
SOURCE AATCC Review, September 2004, vol. 4, no. 9, pp. 31-34
ABSTRACT A sobering reality facing manufacturers today - most of the water, electricity, and gas or oil you buy will eventually be discharged as waste. Money will go down the drain or up in smoke with it - disposed wastewater or airborne exhaust. Disposal may be inevitable, and even beyond your control, but not beyond management. A comprehensive water and energy management program will significantly reduce facility consumption, production costs, and environmental impact. Cycle times can be reduced, productivity increased, first-time quality achieved, and lot-to-lot repeatability improved.
5. TITLE Suppliers Preach the Virtues of Green Adhesives
AUTHOR Valero, Greg
SOURCE Chemical Week, September 15, 2004, vol. 166, no. 30, p. 38
ABSTRACT Adhesives makers say tougher clean-air regulations are forcing them to develop environmentally friendlier products. If that isn't hard enough, then consider marketers must convince fickle customers that the latest "green" adhesives perform just as well as existing formulations. This is proving to be easier said than done, industry members say, because many end users are reluctant to deviate from products with which they're familiar. Previous environmentally compatible formulations often required users to give up performance expectations when switching from traditional adhesives. But manufacturers claim technology has improved to a point where there are discernable differences in performance and working characteristics compared to old solvent-containing adhesives. The latest glues are said to provide optimum performance, low volatile organic compound (VOC) levels and are easy to work with.
6. TITLE Rohm and Haas Studies Biomass, Invests in Fund
SOURCE Chemical & Engineering News, August 9, 2004, vol. 82, no. 32, p. 13
ABSTRACT Rohm and Haas is receiving a $2 million grant from the Department of Energy to develop a new generation of adhesives and sealants derived from renewable materials. Over the next two years, the principal investigator will work with other researchers to substitute sugars, soybean oil, castor oil, and other biomass sources for traditional petrochemical raw materials. Rohm and Haas also sees potential applications for biomass technology in elastomers and foams.
7. TITLE CMR Technology Watch: Immersion Photolithography
AUTHOR Boswell, Clay
SOURCE Chemical Market Reporter, Vol. 265, No. 25, June 21, 2004, pp. FR6 - FR7
ABSTRACT Engineers have developed an ingenious solution to the problem of manufacturing microchips with finer and finer features. The new approach, immersion photolithography, could extend the usefulness of 193 nm technology and, suggest some, even circumvent the use of 157 nm processes. The development of this new technology has been driven, in large part, by the International Technology Roadmap for Semiconductors(ITRS), which presents a set of milestones,called technology nodes, and an ambitious schedule for achieving them. Each node is defined principally by the size of features that can be inscribed on a microchip, which is directly proportional to the wavelength of the light used in the photolithographic process. Reaching each node has therefore meant using light of increasingly shorter wavelength. For example, 365 nm light was used to obtain features as small as 300 nm, but as feature sizes fell toward the 250 nm node, it became necessary to use 248 nm light.
8. TITLE Are Green Buildings Cost-Effective?
AUTHOR Kats, Greg
SOURCE Green@Work, May/June 2004, pp. 23-32
ABSTRACT There is a widespread perception that green buildings - though more attractive from an environmental and health perspective - are substantially more costly than conventional design and may not be justified from a cost benefits perspective. But green or "high-performance"buildings use key resource including energy, water, materials and land more efficiently than building that are just built to code. Consider that US buildings, which represent about half of the nation's wealth, consume 70 percent of the nation's electricity, generate 30 percent of waste, and are responsible for more global warming than any other nation's economy except China's. In contrast, green buildings - with more natural light, better air quality and greater comfort - typically also contribute to improved occupant health, comfort and productivity. A more complete accounting of these costs and benefits demonstrates that green buildings are generally cost effective today, with average financial benefits exceeding additional costs by a factor of 10 to one.
9. TITLE Characterization of Substrate Surface and Coatings: Using Advanced Analytical Tools
AUTHOR Hussain, Amir
SOURCE Paint & Coatings Industry, March 2004, vol. 20, no. 3, pp. 36-40
ABSTRACT High performance coatings in aerospace, automotive, biomedical and electronics applications imply ever-increasing and stricter quality-assurance demands on the component materials and their processing. Coatings end users have focused attention on the dimensional stability of substrates like steel, aluminum, etc., and coating materials like urethanes, epoxy resins, etc. Today it is the interface that is demanding more and more attention rather than the bulk components of the coating and substrate materials. For a durable adhesion, a pretreatment of the substrate is inevitable. The substrate often needs to be cleaned before a primer/coupling agent/plasma is applied. An extremely accurate and reliable characterization of the substrate surface at the nanometer scale is imperative. AFM, contact angle, ESCA and TOFSIMS are extremely useful techniques for combating contamination and providing quality assurance for reproducible pretreatment. As a substrate is coated and cured with a urethane/epoxy system, for example, advance thermal analytical techniques like MDSC, DM(T)A and DE(T)A are proving to be successful tools in ensuring the application and quality of the coating materials. An in-depth understanding of the structure property relationship with regard to mixing ration and cure mode of the coating materials is a prerequisite for their successful application and long-term durability.
10. TITLE Update: 141b Alternatives
SOURCE CleanTech, March 2004, vol. 4, no. 3, p. 26
ABSTRACT Solvent-based parts degreasing remains an exciting, albeit sometimes confusing industry, for those seeking solutions. The competitive landscape of the aerosol market, for example, has taken on a new look as the depletion of HCFC 141b has been realized. While large stockpiles of 141b helped to keep the solvent on the market for some time in various forms, most users have already committed to alternatives. But for those who have not, we offer these tips.
