Investigation of the induction heating behavior of aluminum particles under different filling structures for electromagnetic tapping

To achieve rapid melting of the blocking alloy during the electromagnetic tapping, hot-state physical simulation experiments were carried out to investigate the feasibility of using aluminum particles as the core filling material. The induction heating behaviour and melting mecha...

Effect of graphite incorporation on the compressive strength and wear properties of polyurethane composites

Polyurethane-based composites (PUCs) are promising materials for stretch-forming dies used in aircraft skin components; however, their limited load-bearing capacity and insufficient wear resistance under severe conditions remain major challenges. In this work, graphite powder (GP...

Stearic acid-modified calcium sulfate whiskers as reinforcements for ultra-high molecular weight polyethylene

Industrial solid waste is an abundant but underexploited feedstock for advanced materials production. Herein, we develop a scalable strategy for the high-value utilization of flue gas desulfurization gypsum from Baotou Iron and Steel Group. We converted it into high-aspect-ratio...

Spatiotemporal prediction of two-dimensional surface deformation in gas field incorporating MSBAS-InSAR and deep learning

Continuous extraction-induced deformation from oil and gas fields can trigger destructive geological hazards, significantly threatening underground infrastructure safety. Therefore, reliable surface deformation prediction is crucial for early warning of potential risks in oil and...

Bidirectional higher-order-mode slot antennas with sidelobe suppression

In this paper, three higher-order-mode slot antennas with high gain and bidirectional radiation characteristics are proposed. Each proposed antenna consists of a folded slot fed by a microstrip line. One antenna operates in the fourth-order resonant mode, whereas the other two op...

Through the colonial lens: the Italian populist radical right and foreign policy relations with Italy’s former colonies

This paper draws attention to the role of colonial memory in the Italian populist radical right’s views on Italy’s foreign policy with its former colonies across the Mediterranean (i.e. Libya, Ethiopia, Eritrea and Somalia). While recent academic scholarship has studied the influ...
