: This study sought to examine the effect of thermal welding tonsillectomy that reduces pain and length of anesthesia on emergence agitation. A total of 60 patients (age range, 3–6 years) with chronic recurrent tonsillitis with an indication for tonsillectomy were included. Patients were randomly assigned to 2 groups. The control group (the CD group) was composed of patients undergoing cold dissection (CD) tonsillectomy. The study group (TW group) included patients undergoing thermal welding (TW) tonsillectomy. All patients were given sevoflurane as an anesthetic agent. For all patients, anesthesia time, operation time, extubation time, Pediatric Anesthesia Emergence Delirium scale, pain scale, nausea/vomiting score, and delivery time were recorded. The duration of anesthesia, operation, and delivery was significantly lower in the TW group as compared with the CD group (P = 0.000 < 0001). The pain and agitation scores were significantly lower in the TW group as compared with the CD group (P = 0.000 < 0001). We assume that, besides reducing pain and allowing surgery without bleeding, the TW tonsillectomy method diminishes emergence agitation induced by anesthetic agents, such as sevoflurane.

Insulated gate bipolar transistors (IGBTs), as an important power semiconductor device, are susceptible to thermal stress, thermal fatigue, and mechanical stresses under high-voltage, high-current, and high-power conditions. Elevated heat dissipation within the module leads to fluctuating rises in temperature that accelerate its own degradation and failure, ultimately causing damage to the module as a whole and posing a threat to operator safety. Through ANSYS Workbench simulation analysis, it is possible to accurately predict the temperature distribution, equivalent stress, and equivalent strain of solder materials under actual working conditions, thus revealing the changing laws of the heat-mechanical interaction in solder materials.

Heating techniques have underpinned the progress of the material and manufacturing industries. However, the explosive development of nanomaterials and micro/nanodevices has raised more requirements for the heating technique, including but not limited to high efficiency, low cost, high controllability, good usability, scalability, universality, and eco-friendliness. Carbothermal shock (CTS), a heating technique derived from traditional electrical heating, meets these requirements and is advancing at a high rate.

The performance of sliver nanowire (AgNWs) network flexible transparent electrodes is limited by large contact resistance, making it necessary to perform nanowelding to improve conductivity of the network. However, not all nanowire junctions can be welded. Our work indicates that the welding kinetics between nanowires depend on the crossing angle, with higher surface diffusion velocity prone to welding and fracture at nanowire junctions of crossing angles close to 90 degrees.

The welding of titanium alloys is an important topic in today's industrial field, and the interaction between the solder and the base material is crucial for the quality of the welded parts. The structural, elastic, electronic, and thermal properties of Ti-Al-Me (Me = Cu, Fe and Ni) alloys (TAMs) with the face-centered cubic structures were investigated using plane-wave pseudo potential method in the framework of density functional theory. Based on the calculated elastic constants combined with empirical and semi-empirical formulas, physical properties including ductility/brittleness, hardness and anisotropy were calculated.
