Abstract: Additive-polymer precursor materials for filaments (e.g., for three-dimensional (3D) printing) are provided, as well as methods of fabricating and using the same. One or more two-dimensional (2D) additive materials (e.g., nano materials, such as nanosheets) can be mixed with a polymer base to give an additive-polymer precursor composite material. The additive material can be dissolved in a first solvent to give an additive solution, and the polymer can be dissolved in a second solvent to give a polymer base. The additive solution can be mixed with the polymer base to give a mixed solution. Solvent casting can then be performed on the mixed solution to evaporate the solvent(s) and give the additive-polymer precursor composite material, which can have a layered structure.

Abstract: The fastener container in the present invention includes a lid and a receptacle base as main components combined together. Said lid has a first section and a second section which are connected by a hinge. This invention used the first prominent portion with flexible cushioning effect and the pressing member of the first prominent portion of the first section, and the blocking member and the third recess of the second prominent portion of the second section to reduce the wear and tear between the pressing member and the blocking member, it also can prevent the pressing member from squeezing the blocking member for a long time to result in a problem that the pressing member and the blocking member are deformed and the first section can not be held in the open position, so that the service life of the lid can be extended and the user can easily open or close the first section of the lid to take or place screws or other items.

Abstract: A control device for power supply time of timers comprises an alternative current (AC) power source input module, a direct current (DC) power source supply module, an AC power source output module electrically connected to a load end, a relay, a central control module, a relay driver circuit, a day/night detecting module, a power supply time backward display light set, a power supply time forward display light set, a power supply time backward selection control button and a power supply time forward selection control button. Herein, by pressing the power supply time backward selection control button or the power supply time forward selection control button, one of the power supply time backward display lights or the power supply time forward display lights can be turned on such that the central control module can, based on the sunset time of the previous day as well as the configured power supply backward setting time or power supply forward setting time, postpone or advance the power supply time for the load end in the next day, and then record the sunset time of the next day so as to control the power supply time for the load end in the further next day.
