Abstract: A vehicular laminated glass for separating a vehicle interior from an external environment is presented. The laminated glass includes inner and outer panes made of glass and having respective thicknesses of less than or equal to 0.4 mm, and greater than or equal to 1.5 mm, and an acoustically damping intermediate layer that bonds the inner pane to the outer pane. According to one aspect, the acoustically damping intermediate layer has two outer polymeric layers between which an inner polymeric layer is positioned, the outer polymeric layers having lower elasticity or plasticity than the inner polymeric layer. According to another aspect, the inner polymeric layer has a thickness of 0.05 mm to 0.40 mm, each of the outer polymeric layers have a thickness of 0.20 mm to 0.60 mm, and the total thickness of the acoustically damping intermediate layer is at least 0.70 mm.

Abstract: The interfacial tension between two liquids is determined by: flowing an internal liquid (Li) through an internal flow member (2) and flowing an external liquid (Le) through an external flow member (4), with conditions being first established such that either droplets (G) of the internal liquid are formed in the external liquid, or a continuous jet of the internal liquid is formed in the external liquid, the continuous jet of the internal liquid then being formed in the external liquid or droplets of the internal liquid then being formed in the external liquid, and deducing therefrom the value of the interfacial tension between these two liquids.

Abstract: 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?) 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 (B1-B6).

Abstract: 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.

Abstract: 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.

Abstract: 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<L/2;l?<L?/2).

Abstract: A mixing apparatus is used to effect mixing between one or more fluid streams. The mixing apparatus generally functions by creating a transverse flow component in the fluid flowing within a channel without the use of moving mixing elements. The transverse or helical flow component of the flowing fluid or fluids can be created by weak modulations of the shape of the walls of the channel. Transverse or helical flow component can be created by grooves features defined on the channel wall. Specifically, the present invention can be used in laminarly flowing fluids. The mixing apparatus and methods thereof can effect mixing of a fluid or fluids flowing with a Reynolds number of less than about 100. Thus, the present invention can be used to mix a fluid flowing in the micro-regime. The mixing apparatus can be used to mix a fluid in a microfluidic system to significantly reduce the Taylor dispersion along the principal direction.

Abstract: In order to separate, within a fluid (1), certain particles (2) contained therein, this fluid is arranged in a corridor (C) partly defined by two faces which are close together and substantially parallel to each other and to the direction of separation E and an exciting field is simultaneously applied to the entire volume of fluid contained in this corridor, according to a direction having at least one component perpendicular to the direction E, which exciting field varies along the said direction in a curve consisting of a regular sequence of mutually identical asymmetric patterns, the mean of this field, taken at each instant along the direction E, being zero, and means are provided for repetitively varying the effect of the exciting field on the particles. The substantially parallel faces may be electrodes between which a potential difference source is connected for producing an electric field thereby exciting particles in the corridor (C).
