Disclosed herein are delayed reaction threshold temperature indicators and methods of making and activating the same, the delayed reaction threshold temperature indicators including a first substrate, first and second layers, and a housing secured to the substrate. The first layer includes a first reactant and an optional meltable polymer, and the second layer includes a meltable polymer and a second reactant. The meltable polymer is configured to keep the first and second reactants from interacting with each other. When exposed to temperatures at and/or above a desired threshold for a period of time, the meltable polymer melts and allows the first and second reactants to come into contact with each other, thereby producing a visual change in appearance.

An energy storage system includes a rack having a space inside, a plurality of modules in the space of the rack, each of the plurality of modules including a plurality of battery cells arranged in one direction therein, and a sensing line along one side of the plurality of modules.

A nucleating agent composition, a method of forming the nucleating agent and a device comprising the nucleating agent composition are provided. The nucleating agent comprises a nucleating agent comprises silver halide salt with an average particle size of at least 10 nanometer to no more than 100 microns in a polymeric matrix wherein the polymeric matrix has a viscosity of at least 500 cP to no more than 50,000 cP.

The invention relates to a method for monitoring the temperature of a cryopreserved biological sample. The invention also relates to a device for monitoring the temperature of a cryopreserved biological sample. The device (10) for monitoring the temperature of a cryopreserved biological sample comprises a sample container (1) having a receiving space (2) for receiving a biological sample (6). The device also comprises at least one chamber (11) having an interior that is not fluidically connected to the receiving space (2) and is only partially filled with an indicator substance (7) with a melting temperature in a region of −20° C. to −140° C. The chamber (11) has a barrier (13) that causes the indicator substance (7) to move into a second sub-region (12b) of the chamber (11) when the indicator substance (7) in a first sub-region (12a) of the chamber is in the fluid aggregate state.
