Production of Flocculants, Adsorbents, and Dispersants from Lignin [PDF]
Molecules, 2018 Currently, lignin is mainly produced in pulping processes, but it is considered as an under-utilized chemical since it is being mainly used as a fuel source. Lignin contains many hydroxyl groups that can participate in chemical reactions to produce value-

Regulatory policies for using oil dispersants in the Barents Sea [PDF]
Polar Research, 2015 Use of dispersants requires assessment of which environmental values are at stake. In the Barents Sea this issue is of high concern as large oil spills can cause transboundary pollution, affecting the interests of two neighbouring countries.

The Formulation, Development and Application of Oil Dispersants [PDF]
Journal of Marine Science and Engineering, 2022 Oil spills in open waters pose a significant threat to marine life. The application of dispersant as an oil-spill response is a promising approach to minimize the environmental burden caused by these accidental events.

Do biosurfactants as anti-biofilm agents have a future in industrial water systems?
Frontiers in Bioengineering and Biotechnology, 2023 Biofilms are bacterial communities embedded in exopolymeric substances that form on the surfaces of both man-made and natural structures. Biofilm formation in industrial water systems such as cooling towers results in biofouling and biocorrosion and ...

Dispersion measures and dispersive orderings [PDF]
Statistics & Probability Letters, 2003 In this paper, the comparison of random variables according to the functionals of a general class of dispersion measures is characterized in terms of the dilation order. The Gini's mean difference is a particular member of this general class. In addition, a new and weaker order, called the second-order absolute Lorenz ordering, is introduced, and we ...

Effect of dispersant on the performances of an ice slurry-wet precooling system
Case Studies in Thermal Engineering, 2023 This study addresses the problem of prolonged precooling time and excessive weight loss of fruits and vegetables during postharvest processes. Ice slurry precooling system shows potential but faces challenges like low undercooling and ice blockage ...

Shock Waves in Dispersive Hydrodynamics with Nonconvex Dispersion [PDF]
SIAM Journal on Applied Mathematics, 2017 Dissipationless hydrodynamics regularized by dispersion describe a number of physical media including water waves, nonlinear optics, and Bose-Einstein condensates. As in the classical theory of hyperbolic equations where a non-convex flux leads to non-classical solution structures, a non-convex linear dispersion relation provides an intriguing ...
