Abstract: The invention relates to a flotation agent for phosphate ore, comprising at least one fatty acid and at least one sarcosinate of the formula (I) wherein R is a C7 to C21 alkyl or alkenyl group, which sarcosinate may be present in the form of a cation derived therefrom caused by protonation of the nitrogen atom, wherein the amount of fatty acid is from 70 to 99 wt.-%, and wherein the amount of the sarcosinate of the formula (I) is from 1 to 30 wt.-%.

Abstract: Systems and methods are disclosed herein that generally involve a camera system including a high-quality lens which is selectively attachable to a mobile device, effectively replacing the mobile device's integral lens. The attachable camera system can leverage existing features of the mobile device, such as the display, battery, storage, and sharing functions, allowing the camera system itself to be a relatively simple, lightweight, portable, and inexpensive device. The ability to selectively attach and detach the camera system from the mobile device allows the camera system to be removed when it is desired to maintain the mobile device's favorable weight, size, and ergonomic characteristics. When high quality image or video capture or increased camera flexibility and functionality is desired, the camera system can be attached to the mobile device.

Abstract: The invention relates to a process for the preparation of monolithic xerogels and aerogels of silica/latex hybrids under subcritical conditions. In the two-stage synthesis of these alcogels in the presence of an acid-base catalyst, the hydrolysis and polycondensation of a silicon alkoxide are carried out in an organic medium containing excess water. A latex consisting of polybutyl methacrylate and polybutyl acrylate, modified with alkoxysilane groups, is first synthesized and then incorporated in the mixture either in the first stage in order to effect its co-hydrolysis with the silicon alkoxide, or in the second stage to effect its co-condensation with the previously hydrolysed colloidal silica. The resulting alcogels are aged, washed, and dried under subcritical conditions. This process gives hybrid products containing 0.1-50 wt-% of latex and having a density of 300-1300 kg/m3, a porosity of 40-85%, a specific surface area of 400-900 m2/g and a mean pore diameter of 2-12 nm.
