Abstract: A microwave heat treatment method for granulated blast furnace slag is provided, which includes the following steps: subjecting the granulated blast furnace slag to microwave heat treatment at a frequency of 900-930 MHz and then cooling the slag. Microwave rapid heating is utilized to remove the moisture in the granulated blast furnace slag, stress is generated inside the granulated blast furnace slag particles to promote the formation of cracks or the decomposition of the granulated slag particles into small particles. After the microwave reaches a certain power, the microwave is turned off, an air blower is turned on, and thermal stress is generated inside the granulated blast furnace slag particles, so that the particles are further promoted to generate cracks or fragmentation; and then the desired fine powder can be obtained by ball milling the granulated blast furnace slag after microwave heat treatment for a short time.

Abstract: Three-dimensional printing on a membrane of a filtration device is described herein. Forming the filtration device involves receiving a membrane comprising a porous material, depositing an ink into pores of the porous material, causing the ink to solidify, and continuously building three-dimensional printed structures via micro-stereolithographic three-dimensional printing. Solidifying the ink causes the ink to bond with the membrane.

Abstract: A port listening request dynamically generated by an application process hosted in a container can be identified. Whether the application process hosted in the container is trusted can be determined. Responsive to determining that the application process hosted in the container is trusted, a first port to be used as an external port for the application process can be dynamically selected, and a port assignment can be communicated to a container engine, the port assignment indicating the first port is assigned to the application process. The first port can be mapped to a second port assigned as an internal port for the application process. The first port can be opened for the application process.
