Experimental Characterization of Thermal, Acoustic, Magnetic, and Electrical Properties of Additive Manufactured Composites Reinforced With Ceramic Powders for Robotic Arms

Journal of Applied Polymer Science, Volume 142, Issue 16, April 20, 2025.
ABSTRACT An extensive experimental analysis was conducted to assess the thermal, acoustic, magnetic, and electrical properties of composite materials reinforced with varying ratios of silicon carbide (SiC) and alumina (Al₂O₃) powders, with a focus on enhancing the functionality of robotic arms.

Ultrafast Control of Coherent Acoustic Lattice Dynamics in the Transition Metal Dichalcogenide Alloy WSSe

Advanced Physics Research, EarlyView.
Coherent acoustic phonons are generated and optically controlled in bulk WSSe alloy samples using ultrafast spectroscopy. The alloy exhibits a strong coherent acoustic response, which is not an intermediate state between WS? and WSe?. Instead, a much more complex mechanism is proposed.

How multilingual is scholarly communication? Mapping the global distribution of languages in publications and citations

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Language is a major source of systemic inequities in science, particularly among scholars whose first language is not English. Studies have examined scientists' linguistic practices in specific contexts; few, however, have provided a global analysis of multilingualism in science. Using two major bibliometric databases (OpenAlex and Dimensions),
