As for PM emissions, the presence of water during the intensive formation of soot particles seems to reduce the rate of formation of soot particles and enhance their burnout by increased concentration of oxidation species such as OH [ 9 ].
This is done by controlling the process of spray penetration, chemical and physical atomization, mixture ignition, and combustion and exhaust gas formation.
The first analysis has considered the total fuel as a sum of both the quantity of diesel and water resulting to an increased BSFC with an increase in the percentage of water in the emulsion. A surfactant from Streptococcus thermophilus slows down the colonization of other thermophilic strains of Streptococcus over the steel which are responsible for fouling.
Lecomte has received several awards, including: Most of the biosurfactants and their surface activity are resistant towards environmental factors such as temperature and pH.
Several biosurfactants have shown antimicrobial action against various bacteria, algae, fungi and viruses. Xie is in charge of strategic partnering with a broad responsibility from technology licensing to product promotion and distribution deal to merger and acquisition.
Professor Lacidogna is author of more than publications, among which: Largest content of NO was emitted when the engine was fueled with neat diesel fuel while three phase emulsion fuel prepared by mechanical homogenizer had lowest NO emission.
Synthetic chemical surfactants impose environmental problems and hence, biodegradable biosurfactants from marine microorganisms were concerned for the biosorption of poorly soluble polycyclic aromatic hydrocarbon, phenanthrene contaminated in aquatic surfaces Olivera et al. Member of the Editorial Board of the International Journals: Professor Malgorzata Witko specializes in theoretical chemistry and catalysis.
There have been inconsistent results reported by different researchers with regard to the effect of water content on the engine combustion characteristics. With the fact that the three-phase oil-in-water-in-oil emulsion uses two-stage emulsification processes and requiring two types of surfactants, generally the process cost would be greater than that of a two-phase emulsion process.
Three-Phase Emulsion Two types of three-phase emulsions can be resulted from the three-phase emulsification technique Figure 1 depending on the inner and outer phases, namely, oil-in-water-in-oil and water-in-oil-in-water emulsions. Duringhe was served as vice-dean, executive-dean and dean of this college.
Molecular self-assembly on surfaces is a central theme of his research, with a focus on the relation between structure and function.

Water-in-diesel emulsion (WiDE) is an alternative fuel for CI engines that can be employed with the existing engine setup with no additional engine retrofitting. It has benefits of simultaneous reduction of both and particulate matters in addition to its impact in the combustion efficiency improvement, although this needs further investigation.
Microemulsions MATTHIAS HLOUCHA, BASF Personal Care and Nutrition GmbH, D€usseldorf-Holthausen, Germany The microemulsion is rapidly frozen, followed by rapture and replication of the frac-ture face. Depending on the composition, drop- Bachelor Thesis, University Krefeld the thesis title of “Development of Microemulsion for Transdermal Drug Delivery of Ketoprofen” submitted by Miss Narumon Worachun as a partial fulfillment of the requirements for the degree of Master of Pharmacy in Pharmaceutical Sciences.
In recent years, heavy metals pollution is found to be a serious environmental issue and various technologies are being discovered for their cleanup from environment. The use of biosurfactants for this purpose was found to be an eco-friendly approach and also an alternate to conventional complex.
