Introduction

Photonic crystals with periodic arrangements of dielectric lattices can form forbidden gaps in electromagnetic waves spectra 1, 2 . These artificial crystals can totally reflect the light or electromagnetic waves at wavelengths comparable to the lattice spacing by Bragg deflection. The introduced structural defects in the periodic arrangements can localize the electromagnetic wave energies and WIT Transactions on Ecology and the Environment, Vol 154, 2011 WIT Press www.witpress.com, ISSN...

Corning Advanced Flow reactor

Corning's Advanced-Flow reactors represent one of the possible solutions which open a way for broader employment of continuous-flow production across chemical industry segments. The key principle of the technology is based on use of a continuous-flow modular system, which consists of a set of various fluidic glass modules, where reaction layer and heat exchange layers are combined in a single block, thus allowing excellent control over the reaction temperature due to elimination of hot spots....

Tunable solvents

2.1 Organic aqueous tunable solvent systems (OATS) Organic Aqueous Tunable Solvent (OATS) are homogeneous mixtures of aprotic organics (acetonitrile or tetrahydrofuran) and polar protic solvents (water or polyethylene glycol) that undergo a phase split to form biphasic liquid-liquid mixtures upon the addition of an antisolvent gas. The phase splitting - going from monophasic to biphasic - results from the difference in the antisolvent gas solubility between the aprotic organic solvent and the...

Cluster management

Although collaborative arrangements within many industries are well-known and often successful and appreciated, further optimization of these arrangements is many times possible. By augmenting collaborative agreements and relationships and by linking up with other firms on the same level of the market, a company may enjoy options otherwise unavailable to it, such as better access to markets, pooling or swapping of technologies and production volumes, access to specialized competencies, lower...

Abstract

Ever stricter air quality standards force all activity sectors to take measures to reduce the emission of particles. In the past, dust measurements at stack mostly referred to Total Suspended Particles (TSP), but nowadays there are more and more concerns about the finest fractions. Indeed, when inhaled, small particles can go deeply into the lungs and are thus the most toxic ones. Particulate Matters (PMs) are generally classified in different fractions regarding their size (PM10 PM2.5 PM1...

Possibilities and limitations of LCA for the evaluation of soil remediation and cleanup

Hogeschool-Universiteit Brussel, Centre for Economics and Corporate Sustainability (CEDON), Belgium When evaluating remediation technologies for contaminated soil and groundwater, the beneficial effect of the remediation, namely cleaner soil and groundwater, are mostly emphasized without consideration of the environmental impact of the remediation activities themselves. Nevertheless, practitioners and decision makers can rely on a broad range of decision tools that can help them to achieve a...

Application examples of Corning Advanced Flow reactors

Corning Flow Reactor

Tens of reactions have already been successfully tested with Corning Advanced-FlowTM reactors, including reactions with miscible and immiscible liquids, gases utilization and gases release as well as reactions involving solids formation. Translating lab-scale experiments or pilot-scale tests to the industrial scale production line, we've made estimates of the economic advantage of Corning reactor-based lines over comparable traditional batch processes for several tested applications. Below,...

Materials and methods

2.1 Eco-efficiency measuring methods (EEMMs) For the evaluation of the eco-efficiency of both pharmaceutical production processes (batch vs. continuous), different EEMMs will be used. It is the purpose to calculate the eco-efficiency by using a wide range of different EEMMs and evaluate these results. Using this set of EEMMs will allow better understanding of the principles and possibilities of the EEMMs under consideration. This will contribute to the EEMM inventory to be made during the...

SHESQ management integration

Operational risks may be classified into four distinct management domains safety and health, security, environment, and quality. Management systems and norms are available to organizations in each of the four domains e.g. ISO 9001 2000 quality , OSHAS 18001 2007 safety and health en EMAS2, ISO 14000 2004 environment . The traditional approach of employing a different management system in every domain for dealing with operational risks in a company has resulted in parallel, and thus entirely...

Strong bond cleavage promoted by silyl group migration in a coordination sphere

Dft Reaction Profile

Department of Chemistry, Graduate School of Science, Osaka City University, Sumiyoshi-ku, Japan C-CN bond cleavage in organonitriles was attained in the photoreaction with HSiEt3 in the presence of a catalytic amount of r 5-C5H5 Fe CO 2Me. The reaction sequence was proposed, where silyl migration from Fe to N in the coordinating nitrile is a key step. DFT calculations proposed a silyl migration with small activation energy of 4.0 kcal mol and subsequent C-CN bond cleavage on the Fe coordination...
