Thermal decomposition studies of TNPDU and its mixtures were carried out using a micro differential thermal analyzer (m-DTA) fabricated in our laboratory. Details of the apparatus are given elsewhere The mixtures of the TNPDU with 3-amino-5-nitro-1,2,4-triazole (ANTA),... 

Poly(NIPAM-co-vinyl laurate) (poly(NIPAM-co-VL)) co-polymers were prepared at various feed ratios via conventional radical random co-polymerisation. The formation, composition ratios and molecular weight of co-polymers were examined. The thermoresponsive behaviour of poly(NIPAM) and poly(NIPAM-co-VL) solutions at low and high concentrations were intensively investigated by turbidity measurement, micro-differential scanning calorimetry (Micro-DSC), temperature-variable state fluorescence, IH NMR and DLS [62].

Although we will stick to the IL-6 gene, it should be mentioned at the side that two other RNA polymerases exist in mammalian cells responsible for the synthesis of RNA molecules, which are not translated into proteins ribosomal (rRNA), transfer (tRNA), small nuclear (snRNA), small nucleolar (snoRNA), and some of the recently discovered microRNAs and piRNAs. These RNA molecules act in the process of translation and mRNA turnover. Micro and piRNAs are probably extremely important in the definition of stem cells and of differentiation programs. Some of them are synthesized by RNA polymerase II. 

To differentiate between the micro-mixed reactor with dead-polymer and the by-pass reactor models in this investigation, the effect of mixing speed on the value of "( )" was observed. As illustrated in Table V, the value (j>" is not observed to increase with decreasing mixing speed as would be expected for a by-pass reactor. This rules out the possibility of a by-pass model and further substantiates the dead-polymer model.

Many authors regard chemical micro engineering as a separate, novel discipline (see, e.g., [5]), the term micro-reactor engineering being used already in an early citation [6], What is essentially different about micro reactors, i.e. what differentiates micro-reactor and chemical-micro-processing ... 

For fast reactions Da becomes large. Based on that assumption and standard correlations for mass transfer inside the micro channels, both the model for the micro-channel reactor and the model for the fixed bed can be reformulated in terms of pseudo-homogeneous reaction kinetics. Finally, the concentration profile along the axial direction can be obtained as the solution of an ordinary differential equation. 

Keeping in mind the controversial discussion on new physics in micro reactors [198], we certainly have to be at least as careful when introducing or claiming essentially novel chemical processes. A thorough scientific consideration is required for an exact definition and differentiation here that is beyond the scope of this book. So far, no deep-rooted scientific work has been published analyzing the origin of the novelty of chemistry under micro-channel processing conditions. 

The worst hazard scenarios (excessive temperature and pressure rise accompanied by emission of toxic substances) must be worked out based upon calorimetric measurements (e.g. means to reduce hazards by using the inherent safety concept or Differential Scanning Calorimetry, DSC) and protection measures must be considered. If handling hazardous materials is considered too risky, procedures for generation of the hazardous reactants in situ in the reactor might be developed. Micro-reactor technology could also be an option. Completeness of the data on flammability, explosivity, (auto)ignition, static electricity, safe levels of exposure, environmental protection, transportation, etc. must be checked. Incompatibility of materials to be treated in a plant must be determined.
