New developments based

New Developments Based on Non-Micaceous Systems. The class of single crystal lustrous pigments is not limited to the non-absorbing types like bismuth oxychloride and basic lead carbonate. Recent developments are absorbing pigments such as platelet-like graphite, laminar phthalocyanines and flaky iron oxides. These flakes... 

The Easyhaler (by Orion Pharma, Finland) and the Clickhaler (by Innovata pic, United Kingdom) are available at present in some European markets. Unlike the DPIs described earlier, these two reservoir-type inhalers meter the dose when the patient presses the top of the device similar to actuation of a pressurized metered-dose inhaler. Both devices contain a dose indicator, which is standard for reservoir multidose DPIs. Recently, Innovata presented the Twinhaler for asthma combination therapy, a new development based on the Clickhaler. This device does not require the combined drugs to be formulated in one powder blend but delivers two powder formulations from two reservoirs into one airflow path. 

An important part of modern technology revolves around phenomena at material interfaces. A detailed knowledge of the chemical and physical nature of interfaces is of great value in solving existing problems and creating new developments based on these... 

The Chi fl /P700 ratio has taken the zigzag (2/1/2/1) path over the past fifteen years. I understand that a series of reports are being put out by these workers to detail the experimental results for this new development. Based on the new results, P700 may be considered as a heterodimer consisting of one Chi d and one Chi a molecule each, although, admittedly, definitive evidence for the heterodimer structure remains to be established. 

Environmental considerations and sustainable development criteria when applied to the materials design field should favor the applications based on the organic thermoplastic polymers (64). The high versatility of polypropylene has placed it beyond the border of commodities to become an engineering polymer. Indeed, new developments based on this polyolefin would be the key in the strategic area of the heterogeneous materials based on organic polymers, both from an academic as well as technical point of view. 

The very first systematic chiroptical analyses have been obtained with ORD measurements in the 1950s and 1960s. The dominance of the ORD analyses has been broken by commercial CD instruments in the 1960s when CD and ORD were measurable with an equivalent accuracy. Since that time ORD is just of interest for selected problems. It should be mentioned here that a new development based on the invention of new numerical quantum mechanical methods, which allows calculating [ajS with a sufficient accuracy, may lead to a situation in which even CD, VCD, and ORD measurements can be avoided. Here, in order to avoid experimental artifacts by association, etc., [a]5 has to be extrapolated with c- 0 section on Quantum me-...

The first chapter is of general interest introducing new development in Raman spectroscopy as a powerful tool in Life Science Research. Michael Blades, Georg Schulze, Stanislav Konorov, Christopher Addison, Andrew Jirasek, and Robin Turner discuss new developments based on Fiber-Optic-Linked Raman and Resonance Raman Spectroscopy. 

Ainong the first TFIz mixers to be constructed were those based on room-temperature Schottky diodes [11]. Over the past decade, new mixers based on superconducting tunnel junctions have been developed that have effective noise levels only a few tunes the quantum limit of [12]. Flowever, certain conditions... 

The PVC formulations shown in Table 2 represent typical compounds used by the wine and cable industry. PVC compounders have developed new PVC-based formulations with very good fire and smoke properties (can pass the UL 910 Steiner Tunnel test) that compete with the more expensive fluoropolymers. These can be used in fabricating telecommunication cables usable for plenum area appHcations. 

Composites. The history of phenoHc resin composites goes back to the early development of phenoHc materials, when wood flour, minerals, and colorants were combined with phenoHc resins to produce mol ding compounds. In later appHcations, resin varnishes were developed for kraft paper and textile fabrics to make decorative and industrial laminates. Although phenoHcs have been well characterized in glass-reinforced composites, new developments continue in this area, such as new systems for Hquid-injection molding (LIM) and sheet-molding compounds (SMC). More compHcated composite systems are based on aramid and graphite fibers. 

The future for amino resins and plastics seems secure because they can provide quaHties that are not easily obtained in other ways. New developments will probably be in the areas of more highly specialized materials for treating textiles, paper, etc, and for use with other resins in the formulation of surface coatings, where a small amount of an amino resin can significantly increase the value of a more basic material. Additionally, since amino resins contain a large proportion of nitrogen, a widely abundant element, they may be in a better position to compete with other plastics as raw materials based on carbon compounds become more costly. 

The ethylene-based, balanced vinyl chloride process, which accounts for nearly all capacity worldwide, has been practiced by a variety of vinyl chloride producers since the mid-1950s. The technology is mature, so that the probabiUty of significant changes is low. New developments in production technology will likely be based on incremental improvements in raw material and energy efficiency, environmental impact, safety, and process reUabiUty. 

Grades of polyisobutylene, butyl mbber, halogenated butyl mbber, and partially cross-linked isobutylene—isopiene—divinylbenzene terpolymer have been developed to meet specific processing and property needs. Recently, two new polyisobutylene-based elastomers have been developed. One is now available commercially as Exxon SB Butyl Polymers (32) and the other is under market development as Exxon bromo XP-50. 

Eor the selective pre-concentration of deactivated phenols a new silica-based material with the grafted 2,3,5-triphenyltetrazole was proposed. This method is based on the formation of molecular chai ge-transfer comlexes of 2,3,5-triphenyltetrazole (7t-acceptor) with picric acid (7t-donor) in the phase of the sorbent. Proposed SPE is suitable for HPEC analysis of nitrophenols after their desorption by acetonitrile. Test-system for visual monitoring of polynitrophenols under their maximum concentration limits was developed using the proposed adsorbent. 

Until the late 1990s, Waspaloy was still the best alloy available for the majority of hot gas turboexpanders used in industry and, until recently, it continued to offer the many special characteristic needed for hot gas expander applications. However, a new development followed in 2000 when the Ebara Corporation (Japan) released data on a nickel-base superalloy. 

The review of the data portion of the Indian Point 2 (IP2) and 3 (IPS) PRA (a 1982 internal document prepared by Consolidated Edison and the New York Power Authority) is confined to the plant-specific and generic component failure and service hour data sections because these were the only segments available to the reviewers. The LERs produced during a ten-year span of IP2 s operation were evaluated to determine their applicability to the PRA data needs. It was eventually decided to use only the LERs generated after IP2 became critical (from May 23, 1973 to December 31, 1979) for the component data base development, based on the availability of failure event information and more uniform operability, testing, and reporting criteria.
