Research on the optical coherence manipulation has made significant progress, but the modulation rate of conventional tailoring technology is too low, which has become a key factor hindering its transition from laboratory to practical application. Here, we utilize lithium niobate films (LNF) modulator to achieve high-speed optical coherence manipulation based on its high-speed electro-optical modulation capability. Our experimental modulation rate reaches 350 kHz, which is about 20 times higher than the fastest modulation rate reported so far. This design strategy provides a simple rule for high-speed optical coherence manipulation based on electro-optical modulation, paving the way for further practical applications of optical coherence manipulation technology.

 

Researchers from the University of Münster have succeeded for the first time in using spin-polarised scanning tunnelling microscopy to image structural and magnetic properties that lie beneath the surface of a layered system of 2D graphene and iron

Two junior research groups at Ruhr University Bochum, Germany, have developed a drug complex that kills cancer cells in such a clever manner that they raise a red flag as they die. They signal to the immune system that something is seriously wrong with this type of cell. This teaches the immune cells to destroy such cancer cells—even if they are not in the vicinity of the original tumor. This could remove metastases that develop at distant sites in the body. Dr. Johannes Karges from the Department of Chemistry and Biochemistry and Dr. Carlos Plaza-Sirvent from the Department of Medicine present their findings in the Journal of Medicinal Chemistry on July 17, 2025.

Extreme environments demand smarter sensors! A team from Zhejiang University has developed a laser-induced, in-situ fabrication method for thin-film temperature sensors with no complex layering, no extra coatings.

💡 Their approach forms conductive & antioxidative layers simultaneously, enabling real-time monitoring from −50 °C to 950 °C with remarkable stability.
📈 Just 1.2% drift over 20 hours under heat, shock, wear, and vibration.

A team of scientists from the IBS Center for Climate Physics (ICCP), Pusan National University in South Korea and the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), Bremerhaven, Germany has achieved an important breakthrough in climate modeling, providing unprecedented insights into Earth's future climate and its variability. Their research was published in the open access journal Earth System Dynamics.

Researchers have solved a mystery that has confounded scientists for 80 years: the crystal structure of the tetra-n-butylammonium bromide (TBAB) hydrate TBAB·26H₂O. This substance belongs to a class of crystalline materials called semiclathrate hydrates, which form from the combination of ions and water. Since its discovery in 1940, this TBAB hydrate has been widely used in a range of applications, including air conditioning. Understanding the crystal structure of this important semiclathrate hydrate will help scientists and engineers better utilize TBAB hydrate.

Penn Engineers reveal a new model that describes how mechanical stress fuels chemical reactions and why that could help reshape green manufacturing and lubricant design.
