Provided is a method to increase the growth of a plant by coating a seed of said plant with a composition comprising at least one of various cationic compounds; notably permitting to develop its biomass and reach its maturity. Provided also is a seed coating composition used in such a method.

Growth enhancement of plant

Provided is a composition, notably a fabric conditioning composition, comprising (a) a quaternary ammonium compound; (b) a cationic polysaccharide; (c) a first non-ionic polysaccharide; and (d) a second non-ionic polysaccharide, wherein the second non-ionic polysaccharide is different from the first non-ionic polysaccharide and the second non-ionic polysaccharide has a Molar Substitution (MS) in the range of 0.2 to 1.8.

Composition comprising a quat, cationic polysaccharide, and a mixture of nonionic polysaccharides

Provided is a method for preventing soil erosion in which a nonionic guar and/or a cationic guar is applied on or into the soil. A method for preventing water runoff of a soil in which a nonionic guar and/or a cationic guar is applied on or into the soil is also provided. A treated soil against the soil erosion susceptible to be obtained by the method for preventing soil erosion in which a nonionic guar and/or a cationic guar is applied on or into the soil is also provided.

Method for preventing soil erosion

The present invention concerns a method to increase the growth of a plant by coating a seed of said plant with a composition comprising at least a cationic guar; notably permitting to develop its biomass and reach its maturity. The invention also concerns a seed coating composition used in such a method.

The present invention relates to methods of improving germination rates of plants or crops, and of preventing or arresting water evaporation loss from targeted soil areas by use of soil additives, which allow for improved water utilization by crops, plants, grasses, vegetation, etc.

The present invention relates to a process which comprises preparing polymers. The process uses an appropriate installation, and may comprise determining at least one parameter of a physical and/or chemical conversion. The invention also relates to a corresponding screening process. According to this process, a polymerization reaction medium is made to flow in a tubular flow member.

Process for preparing a polymer

Method and installation for determining rheological characteristics of a fluid, and corresponding identifying method

Operation of a microfluidic flow device includes providing a microfluidic flow device including a body and at least one flow microchannel for transferring a mixture (G; T') of at least two components being formed within the body, in which said mixture (G; T&#x2032;) of the at least two components is caused to flow in the flow microchannel and the mixture is analyzed in at least one derived branch (B-B).

Microfluidic flow devices for determining parameters of physical and/or chemical transformations

A microfluidic flow device includes at least one flow channel flowing into a branch point, to which at least two branched channels are connected, and at least one linking channel interconnecting the two branched channels. The linking channel flows into each branched channel at a short-circuit point which is preferably located at less than half of the length of each branched channel.

Microfluidic flow device and method for use thereof

The invention relates phase-separated compositions comprising two miscible solvents. More specifically, the invention relates to compositions comprising liquid droplets of an internal phase comprising a solvent B and further compounds, said droplets being dispersed in an external phase comprising solvent A, wherein solvent A and solvent B are miscible. Such compositions find use in various technical fields, including encapsulation, vectorisation, protection of compounds, separations, and chemical reactions in a dispersed medium.
