Abstract: An energy storage system and a fire protection method for the energy storage system are disclosed. The energy storage system includes: a storage assembly, configured to store a battery cell; and a tire prevention assembly, including a plate and a thermometric optical fiber disposed on the plate, where the plate is disposed opposite to the storage assembly, and the thermometric optical fiber is configured to sense a temperature of the battery cell so as to send a fire signal when the temperature of the battery cell reaches a threshold. The thermometric optical fiber is disposed on a side of the plate and extends along a curved path, the side being oriented toward the storage assembly.

Abstract: The present invention is directed to metallic particles coated with glycosaminoglycans and methods for preparing them. Methods of using such glycosaminoglycan-coated metallic particles in biomedical and other applications are also disclosed. In certain embodiments, methods for assaying glycosaminoglycan-degrading activity in biological fluids, test samples, and/or therapeutic formulations using the glycosaminoglycan-coated particles are provided. Such methods may be used, for example, in diagnostic tests for diseases such as cancer, inflammatory diseases, or autoimmune diseases and to test activity of enzymes being developed as therapeutics.
