Here, researchers from Technical Institute of Physics and Chemistry, CAS, fabricated customized micropatterns consisting of hydrogel core-shell nanoparticles via the femtosecond laser maskless optical projection lithography (Fs-MOPL) technique for the first time.

Their work offers an approach to fabricating hydrogel core-shell nanoparticles without high temperature or multiple steps.

Researchers at Incheon National University explored how domestic public opinion influences foreign policy alignment decisions among U.S. allies during great power competition. Using a survey experiment centered on South Korea’s potential Quad membership, they found that leaders face audience costs when reversing alignment commitments, particularly from pro-U.S. constituents. The study highlights how shifting public preferences can strengthen or weaken alignment credibility in international politics.
