Abstract: The present invention provides hair straightening compositions comprising acrylic polymers configured to crosslink upon drying and thereby to form a film that is able to preserve hair in straightened conformation. Also provided is a hair straightening cosmetic formulation comprising said hair straightening composition and its use in straightening hair or preserving hair in a straightened conformation. The hair straightening effect is temporary and can be removed when the formulation is washed away in water or with shampoo. The cosmetic formulations of the present invention are ready to use formulations and may be applied frequently.

Abstract: The present invention provides a two-component printable conductive composition comprising, as separate components, a metallic component comprising a high melting point (HMP) metal or metal alloy powder having a mean particle size below about 15 ?m; and a fluxing component comprising an organic acid and an organic solvent. The organic acid is characterized by having at least two carboxylic groups and a first logarithmic acid dissociation constant (p Ka1) of at most about 4. These two components are manufactured and stored separately and are mixed together shortly before the combined conductive composition is used for printing. Further provided is a kit comprising the two-component composition, wherein the metallic component and the fluxing component are disposed in separate containers.

Abstract: A sheet-fed system designed to print multilayer PCBs is introduced. The system consists of four main blocks; a drilling station, a patterning station, a stacking/bonding station, and a sintering zone. The substrate PCB is shuttled between these various stations, to have vias drilled, to be attached to stacks of previously-processed layers, to be covered with conductive paths by means of the aforementioned ink, and to have the ink sintered under a controlled temperature and atmosphere. Patterning is accomplished by means of a novel two-step method involving both high-temperature conductive elements, low-temperature conductive elements, and flux. Two such compositions are successively applied and individually sintered to form a single conductive path; the second application serves to fill the porosities of the first layer. By this method, a highly-conductive trace is obtained without requiring high temperatures, which in turn allows use of common substrates including polymers.

Abstract: A method of distributing fragile insects in a distribution involving a wind shear, comprises, encapsulating the insects into a bubble and then releasing the bubble into the wind shear so that the bubble protects the insect from the wind shear. The insect may be inserted before or after formation of the bubble at any stage of the insect life cycle and the bubble may be uniform or made of a slow dissolving and a quick dissolving part. The bubbles are useful for aerial distribution of sterile male mosquitoes.

Abstract: The disclosure is directed to an intermediate filtering membrane comprising: a filtering membrane having a charged or polar surface; and a transiently coupled charged compound, wherein the charged compound has an opposite charge to the membrane charge. Likewise, provided herein are methods and kits utilizing the intermediate membrane for various filtering membranes operations.

Abstract: The present invention related to compositions (deodorizing or not) for human and animal excrement, especially pest and livestock, comprised of acidic agents and water soluble polymers, wherein the acidic agents are base neutralizers for the ammonia and indolic amines in the excrement and the water soluble polymers are barrier forming agents for the vapor of the offensive odor producing compounds in the excrement and for slowing down the air oxidative and enzymatic nitrification of the excrement ammonia and organic nitrogen thus dispersing the attenuating nitrate concentrations in the environment. The present invention further relates to a method of applying said compositions to excrement. Said compositions may be applied to excrement in liquid form by mixing the liquid composition together with the excrement, or in the form of a spray, by spraying the composition directly onto the excrement.
