Abstract: Disclosed herein are unitary printed circuit boards (PCBs) and methods of using them for testing an integrated circuit (IC). In some embodiments, a unitary PCB comprises a main board portion and a flexible PCB portion, which are configured to be detached from each other at a separation location on the unitary PCB. The main board portion comprises a plurality of pads, and the flexible PCB portion comprises a plurality of through-holes, where a layout of the through-holes corresponds to a layout of the plurality of pads. In some embodiments, a method of testing an IC of a device comprises separating the unitary PBC into a main board portion and a flexible PCB portion, attaching the IC to the main board portion, soldering the main board portion to a platform PCB of the device, and attaching the flexible PCB portion to the main board portion.

Abstract: The present invention provides a composition comprising: a. a water-based polymer emulsion from 10 wt % to 90 wt % of the composition; and b. Dead Sea salt from 5 wt % to 80 wt % of the composition.

Abstract: The present invention provides for a composition, including: a sufficient first amount of a first active agent dispersion; where the first active agent dispersion has a pKa of 0.1-2.0, where the first active agent dispersion is selected from the group consisting of: an acid cation exchange resin, an acidic zeolite, an acidic clay, an organic acid, an inorganic acid, and any combination thereof, and where the first active agent dispersion includes a plurality of particles; where the plurality of particles has a median diameter of between 0.5-1000 micrometers; and a sufficient second amount of at least one chlorite salt dispersion; where, when the composition is contacted with an aqueous liquid, the sufficient first amount of the first active agent dispersion and the sufficient second amount of the at least one chlorite salt dispersion results in a generation of chlorine dioxide radicals.

Abstract: Provided herein are biocidic compositions including an ion exchange material, wherein when said material is in an environment capable of transporting H+, said ion exchange material is adapted to cause the death of at least one cell within or in contact with said environment. A selectively permeable barrier layer may be provided covering the ion exchange material. Also provided herein are methods of making the foregoing biocidic compositions. In addition, provided herein are methods of using the foregoing biocidic compositions to cause the death of at least one cell.
