This study presents a new 1.8-billion-year full-plate tectonic model, integrating geological and paleomagnetic data to reconstruct supercontinent cycles (Nuna, Rodinia, Pangea), revealing dynamic Proterozoic tectonics and challenging the “boring billion” hypothesis. 

Blockchain systems have long struggled to balance efficiency and reliability. 

This study identifies photon loss as the key bottleneck limiting the efficiency of bifacial perovskite solar cells (Bi-PSCs). The researchers proposed a strategy for constructing high-quality thick films by regulating precursor crystallization, which reduces current loss to an unprecedented 1.67 mA cm^-2 and achieves a record-breaking power conversion efficiency. Meanwhile, the long-term stability of the devices is significantly enhanced.

In a paper published in National Science Review, scientists used machine learning to reconstruct the geochemical composition of the Hadean continental crust. Based on Jack Hills zircons, the study reveals a felsic crust dominated by TTGs and potassic granites, formed through partial melting of mafic protocrust during crustal thickening. The results provide new constraints on early Earth’s tectonic evolution.

In this breakthrough acoustic experiment, researchers have directly observed anti-Klein tunneling—a quantum-like phenomenon where chiral sound waves are entirely blocked by a barrier. Using a tunable bilayer phononic crystal, the team demonstrated switchable transitions between full transmission and total reflection, mimicking quantum paradoxes with sound. This work confirms a long-standing theoretical prediction and opens new possibilities for topological wave control and quantum-inspired acoustic devices.

Magic fluorinated molecules like PFBT drastically reduce contact resistance by a factor of 16 in flexible organic transistor, diminish energy barriers by 73%, and enhance operational metrics. Derived from in-situ chemical reactions at metal-organic semiconductor buried interfaces, this breakthrough eliminates interfacial trap states and mitigates Fermi-level pinning. This innovation sparks visions of sleek bendable screens and intuitive wearable technology, reshaping flexible electronics with elegance and precision.
