摘要:
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.

摘要:
The method comprises: causing a reference fluid (F2) having known rheological characteristics, and an unknown fluid (F1) to flow in parallel in a microchannel (126); identifying at least one data item representative of the interface (I) between these fluids in the parallel flow, and in particular the position of said interface; and determining the rheological characteristics of the unknown fluid, from the or each identified data item.
摘要:
This microfluidic flow device comprises: at least one flow channel (A), flowing into a branch point (D), to which at least two branched channels (B, B′) are connected, and at least one linking channel (BL) connecting the two branched channels, the linking channel flowing into each branched channel at a short-circuit point (PCC, PCC′) which is preferably located at less than half of the length of each branched channel (l

摘要:
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.

摘要:
Microfluidic flow devices for determining parameters of a physical and/or chemical transformation include a body (2), at least one flow microchannel (36) for transferring a mixture (G; T′) of at least two components, such microchannel being formed within the body (2), the or each flow microchannel (36) opening out into at least one fork (D1-D6; D′1-D′6; D″1-D″n; d1-dn; d′1-d′n) enabling a tree structure to be created having a plurality of derived branches (B1-B6; B′1-B′6; B″1-B″n; b1-bn; b′1-b′n), this tree structure being asymmetrical.
摘要:
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.
摘要:
A polyester soil-release polymer (a) and a cosurfactant (b) are used in a laundry composition to improve primary detergency, secondary detergency, and/or soil anti-redeposition and/or to allow a reduction of the amount of surfactant(s) and/or builder(s). Also disclosed is a performance additive comprising at least 20% by weight as actives, of a mixture of (a), (b) and optionally water or other products, in an amount by weight if present of lower than 80%, and the performance additive is mixed with other ingredients to make a laundry composition.
