Abstract: A resin for grayscale digital light processing 3D printing includes a donor moiety, an acceptor moiety, a rigid moiety, a photoinitiator, and a photoabsorber. The donor moiety is an acrylate monomer with a side group of a free carbonyl, a primary amine on an acrylate, a secondary amine on an acrylate, and/or a tertiary amine on an acrylate. The acceptor moiety is different than the donor moiety and is an acrylate monomer with a side group of a free hydroxy, a primary amine, secondary amine, and/or an imine. And the rigid moiety is acrylate monomer with a side group of a cyclohexyl, a substituted cyclohexyl, or a bicyclic structure. A monolithic structure formed from the resin using grayscale digital light processing 3D printing can have a Young's modulus ranging from 0.1 MPa to 100 MPa.

Abstract: Methods for recycling thermoset polymers, particularly by changing them into dynamic networks with the use of an appropriate catalyst solution which transforms the thermoset polymer into a vitrimer-like composition. The methods include the step of swelling a crosslinked thermoset polymer in a solution including a catalyst, whereby the catalyst diffuses into the thermoset polymer, in particular into the thermoset network. Upon removal of the liquid portion of the solution, such as solvent, the catalyst facilitates the occurrence of exchange reactions at elevated temperatures, rendering the system a dynamic network. The vitrimerized composition having the thermoset polymer and catalyst is recyclable and processable and thus suitable for many end uses.

Abstract: Disclosed is a method of high-precision 3D reconstruction of existing railway track lines based on UAV multi-view images, including: acquiring initial data, acquiring a UAV image rail top centerline, calculating a rail top centerline based on a nonlinear least squares method, and calculating three-dimensional coordinates of the rail centerline. Based on the multi-view geometry principle in computer vision and photogrammetry, object space coordinates of the line can be directly calculated by using image information, which does not require outdoor workers to work online and can effectively improve the safety of railway operation line surveying and mapping. Therefore, this method has important engineering application value and application prospect.

Abstract: Thermosetting plastics are recycled by process that begins with grinding the plastic into small pieces. This particulate is then mixed with a catalyst and ball mill milled to a fine powder, which can then be reprocessed via molding (e.g., hot-press, injection, etc.).

Abstract: A pallet includes a main extension member and support members. The main extension member includes a rotary sleeve and two threaded bars, which are respectively inserted into the rotary sleeve through two ends of the rotary sleeve to be connected in a rotatable manner through threading engagement. The support members each include first and second support elements pivoted to each other. An end of each threaded bar that is distant from the rotary sleeve is pivotally connected to the pivotal connection between the first and second support elements. Rotation of the rotary sleeve allows for adjustment of a distance between the two threaded bars to change a bending condition therebetween so as to vary a size of the pallet. The variation of the size of the pallet is thus made flexible to suit the need for transportation of products of various sizes and thus saving costs of transportation and storage.
