Microstructure and mechanical properties of fine-grained K417 superalloy ring fabricated by vacuum centrifugal casting

The K417 superalloy rings are extensively applied in the aerospace field for its excellent high-temperature strength and outstanding high-temperature creep resistance. However, conventional manufacturing routes face challenges in complex processing procedures and low material uti...

Air pollution and early-onset lung cancer: from environmental carcinogenesis to early intervention strategies.

Air pollution remains a global public health challenge, with nearly the global population (99%) breathing air that exceeds World Health Organization (WHO) guideline limits-annual means of 5 μg/m3 for PM2.5 and 15 μg/m3 for PM10. Both household and ambient air pollution are classi...

Controllable AI modeling of northern and southern timbercraft convergence in Qing interior canopies

This study examines interior canopies from the Qianlong–Jiaqing era (1736–1820) of the Qing dynasty to model northern–southern timbercraft convergence through controllable AI generation. We constructed northern official and southern garden semantic lexicons, trained dual LoRA mod...

Elevated substrate preheating tailors microstructural evolution and enhances fatigue resistance in laser powder bed fusion H13 tool steel

Fatigue performance remains a key limitation for laser powder bed fusion (LPBF) tool steels due to the strong coupling between process-induced defects and microstructural heterogeneity. Elevated substrate preheating has been proposed as an effective strategy to improve the proces...

Thickness-dependent electronic transition and emergent edge states in few-layer SmTe(111) films

Two-dimensional rare-earth chalcogenides exhibit promising quantum phenomena for nanoelectronics. We synthesized non-van der Waals samarium telluride (SmTe) films on Ag(111) through ultrahigh vacuum co-deposition and characterized them using scanning tunneling microscopy. Our mea...

Hydroxyl-directed differentiation of photocyclization pathways in triphenylamine monitored by transient absorption spectroscopy

Photoinduced [6π]-electrocyclization of triphenylamine provides an efficient route to the construction of carbazole frameworks. In this work, 4-(diphenylamino)phenol (TPA-OH) was selected as a model compound to examine how hydroxyl substitution breaks the symmetry of triphenylami...
