Alumina (Al₂O₃) ceramics represent a crucial category of advanced structural engineering materials due to their excellent physicochemical properties and relatively low cost. However, their broader application has been limited by low fracture toughness, making toughening a key research focus for Al₂O₃ ceramics. Silicon carbide whiskers (SiC_w) are among the most effective toughening agents for Al₂O₃ ceramics, but recent studies have primarily focused on optimizing SiC_w introduction methods and sintering processes. Departing from conventional approaches, the present research has pioneered a novel strategy—designing a core-shell composite structured SiC_w as the toughening phase for Al₂O₃ ceramics, thus offering a new perspective for Al₂O₃ ceramic toughening studies.

An international study led by researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) shows how iNaturalist, the global technology platform through which everyday people share wildlife photos via a website and an app, is doing far more than connecting users with nature. 

It’s rapidly becoming a cornerstone of scientific research.

Though scientists have long understood how lightning strikes, the precise atmospheric events that trigger it within thunderclouds remained a perplexing mystery. The mystery may be solved, thanks to a team of researchers led by Victor Pasko, professor of electrical engineering in the Penn State School of Electrical Engineering and Computer Science, that has revealed the powerful chain reaction that triggers lightning.

Engineers from RMIT University have produced a new type of 3D-printed titanium that’s about a third cheaper than commonly used titanium alloys.

Humanity has an insatiable appetite for ammonia: this substance is used to make fertilizer, which in turn is used in most modern agriculture. Until now, the Haber-Bosch process has been the method of choice for extracting nitrogen from the seemingly inexhaustible atmosphere and binding it in the form of ammonia. However, this method requires an extremely large amount of methane gas and energy. Prof. Nikolay Kornienko from the University of Bonn has discovered a more climate-friendly alternative for producing ammonia from renewable energy sources. The research team is now presenting its findings in the journal Nature Communications. 

University Startup Entrepreneurs (USEs) possess the scientific knowledge and institutional support necessary to build and sustain high-tech ventures. But why are they not as successful as Corporate Startup Entrepreneurs (CSEs)? Empirical evidence suggests that differences in motivations, culture, knowledge, and identity could be the answer. USEs seek intellectual stimulation over financial success, struggle with accepting their entrepreneurial identity, and lack knowledge of the market and customers, putting them at a disadvantage compared to CSEs.
