Methods are described for treatment of aramid fibers to modify the surface of the fibers. The treated fibers have improved adhesion to elastomer materials as compared to untreated fibers. Modification methods include irradiating the fibers, compressing and straining the fibers under a constant pull force and immersing the fibers in a coupling agent fluid. The treated fibers can be used with elastomers and provide reinforcement elements in products such as tires.

A chip stack packaging structure and method includes: a base chip layer, including a base chip with pins on the front surface; at least one stacked chip layer, which is formed on the base chip layer, has an inter-chip insulating layer and at least one stacked chip attached to the insulating layer and pins on the front surface, where the front surface of the stacked chip faces the front surface of the base chip; and a top insulating layer, stacked on the stacked chip layer farthest from the base chip layer. A vertical interconnection hole is formed inside the inter-chip insulating layer to allow the corresponding pins to be communicated vertically so as to be electrically connected. Inside the vertical interconnection hole, a conductive material layer is formed that makes the corresponding pins electrically connected; the stacked chip is thinned and reduced after being attached to the inter-chip insulating layer.

A liquid crystal mixture and a temperature-responsive infrared reflection device made by using the liquid crystal mixture containing potassium laurate. Infrared light can pass through the device within a non-working temperature range, and a chiral dopant enables potassium laurate to form a cholesteric phase within a working temperature range. The birefringence value of the potassium laurate gradually increases with the increase of temperature between 12.5&#xb0; C. and 26&#xb0; C., so that the infrared reflection bandwidth of the device constantly increases. The birefringence value of the potassium laurate gradually decreases with the increase of temperature between 26&#xb0; C. and 54.5&#xb0; C., so that the infrared reflection bandwidth of the device constantly decreases. The infrared reflection bandwidth of the infrared reflection device can vary with temperature by adjusting the proportions of the ingredients of the liquid crystal mixture containing potassium laurate.
