13C PEG as an In Vivo Macromolecular Probe for MRI and Biophysical Studies of Detergent-Peptide and Detergent-Detergent Interactions using NMR
… thesis describes biophysical interactions of detergents with either peptides or other detergent molecules. Firstly, the effects induced by a single polar substitution on the structure and topology of model α-helical transmembrane segments were investigated. Upon substitution of a central …

The atomisation of detergent slurries
… pressure nozzles. A range of non-Newtonian detergent slurries were tested but the results are of wider application and parallel work was undertaken with water, ionic solutions and chalk slurries. Six centrifugal pressure nozzles were used and the drop-size distributions correlated as a …

Deconvolution of Membrane Protein-Detergent Complex Interactions
… excessive aggregation in aqueous solutions. Detergents have been extensively exploited to mitigate this aggregation, and accomplish this by protecting the hydrophobic exterior of the membrane protein with their hydrophobic tails, while the polar heads of the detergents interact with the …

Hydrogen Abstraction by the Nighttime Atmospheric Detergent NO3·: Fundamental Principles
The nitrate radical (NO3·) was first identified as early as the 1881, but its role in atmospheric oxidation has only been identified within recent decades. Due to its high one-electron reduction potential and its reactivity toward a diverse set of substrates, it dominates nighttime atmospheric …

Toxic Effects of an Anionic Detergent on the Gills of Trout
The literature on the toxicity of synthetic detergents to fish and aquatic invertebrates is reviewed. The pathological effects of an anionic detergent, sodium lauryl sulphate, on the gills of rainbow trout have been studied by light and electron microscopy. At lethal concentrations up to about 120 …

Methods for detailed study of detergent action in cleaning food soils
Dishwasher detergent formulations contain components which dictate the chemical environment (pH, wettability, solubility) of cleaning solutions. The role of these factors, as well as temperature, in the mechanisms controlling the cleaning of a baked heterogeneous food soil from stainless steel …

Estimation of indigestible neutral detergent fiber in forages from cell wall components
… first three components are measured as neutral detergent fibre (NDF). The NDF is either slowly digestible or indigestible (iNDF). Even if indigestible iNDF is unavailable to microbes, it is a critical component affecting the nutritional value of feeds. Organic matter digestibility is influenced …

Determination of trace elements in crude oils by ICP-MS using detergent microemulsion.
A method was developed and evaluated in terms of its analytical performance for the determination of Ti, V, Cr, Mn, Ni, Cu, Mo, Cd, Sn and Pb concentrations in three Libyan crude oil samples using ICP-MS. The samples were introduced to the plasma after the formation of microemulsions in which …

Production of mid-chain branched detergent-range olefins over shape-selective acid catalysts
… potential feedstocks for selectively branched detergents which have improved surfactant properties while retaining good biodegradability. NMR and GC-MS analyses of hydrogenated dimer product fractions indicated that all catalysts produce branched products, and that these products are …

Hydroformylation of high temperature Fischer-Tropsch synthol products for the production of detergent alcohols
… These alcohols are precursors for biodegradable detergents. The HTF-T product targeted as a feedstock source was Synthol Light Oil (SLO), in the C₈ to C₁₂ range. The aim of the work was to identify a suitable hydroformylation catalyst system for use with SLO feeds. Process variables such as feed …

Detergent effects on disinfectant susceptibility of Escherichia coli and listeria monocytogenes attached to stainless steel
This study investigated the effect of detergent treatment on susceptibility of attached Escherichia coli and Listeria monocytogenes to subsequent disinfectant treatment, in relation to food industry cleaning procedures. E. coli attached to stainless steel surfaces became significantly more …

The effect of alternative detergent builders on the nutrient removal activated sludge sewage treatment process
… two main sources, namely human waste {±60) and detergents {±40) (Heynike and Wiechers, 1986). There is an argument for a ban on phosphate in detergents to reduce the phosphate load on sewage treatment plants and thereby limit phosphate discharges via treated municipal effluent. The removal of …

Effects of hydraulic loading and laundry detergent on the operation of aerobic package treatment systems
… systems: hydraulic retention time, laundry detergents, and hydraulic surges. To determine the effect of hydraulic retention time on system performance, six bench scale activated sludge systems were constructed. Wastewater from an actual residence was collected twice per week and fed to the …
