Researchers from the University of Shanghai for Science and Technology and the University of Illinois Urbana-Champaign have developed and validated a coupled xenon-transport and reactor dynamics model for molten salt reactors. This model enables simulations of dynamic and frequency response of liquid-fueled MSRs, which is validated against a broad spectrum of experiment data from the MSRE. The new simulation framework reveals the unique power-to-flowrate and power-to-void frequency responses of the MSRE. In addition, plant responses during the unique initiating events of off-gas system blockage and loss of circulating voids are simulated.

Plant-based seafood alternatives should have similar flavors, textures and nutritional content to the foods they mimic. And recreating the properties of fried calamari rings, which have a neutral flavor and a firm, chewy texture after being cooked, has been a challenge. Building off previous research, a team publishing in ACS Food Science & Technology describes successfully using plant-based ingredients to mimic calamari that matches the real seafood’s characteristic softness and elasticity.

The U.S. National Science Foundation Daniel K. Inouye Solar Telescope, the world’s most powerful solar telescope, operated by the NSF National Solar Observatory (NSO) near the summit of Maui’s Haleakalā, recently reached a major milestone as one of its groundbreaking instruments, the Visible Tunable Filter (VTF) achieved first light. The VTF is the world’s largest imaging spectro-polarimeter - a highly sophisticated instrument designed and built by a team at the Institut für Sonnenphysik (KIS) in Freiburg, Germany. It is the fifth and final first-generation instrument to be integrated, emerging as a crucial one among the Inouye’s instrument suite.

The world's largest solar telescope, the U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope in Hawaii, has reached an important milestone. After almost 15 years of preparation, the German instrument for the Inouye Solar Telescope, the Visible Tunable Filtergraph (VTF), has now taken its first images. The imaging spectro-polarimeter was developed and built at the Institute for Solar Physics (KIS) in Freiburg (Germany). The Max Planck Institute for Solar System Research (MPS) in Göttingen (Germany) is a partner in the project. The data published now were obtained during the technical commissioning of the instrument. VTF analyzes the sunlight captured by the Inouye Solar Telescope in more detail than ever before and, among other things, extracts information on the flow velocity of the solar plasma and the magnetic field strength at the visible surface of the Sun and in the directly adjacent gas layers above. Even in the current technical test phase, VTF is making smallest structures visible. In later scientific operation, when the data is extensively post-processed, the resolution will improve further. With a primary mirror diameter of four meters, the Inouye Solar Telescope is the largest in the world. Thanks to the optimal observational conditions on the Hawaiian volcano

Carbon-containing meteorites look like they had less severe impacts than those without carbon because the evidence was blasted into space by gases produced during the impact. The Kobe University discovery not only solves a 30-year-old mystery, but also provides guidelines for a future sampling mission to Ceres.

Researchers from Max Born Institute have demonstrated a successful way to control and manipulate nanoscale magnetic bits — the building blocks of digital data — using an ultrafast laser pulse and plasmonic gold nanostructures. The findings were published in Nano Letters.

Two-dimensional porphyrin-based COFs show great promise for photocatalytic CO₂ reduction, yet their π-π stacking often impedes active site exposure and charge transfer. Researchers developed a series of porphyrin COFs with tunably twisted linkers. The N-N-linked twisted unit in NN-Por-COF creates a remarkably undulating layered structure that enhances mass transport and exposes more active sites, while simultaneously modulating the electronic structure of cobalt-porphyrin to reduce reaction barriers. This dual structural and electronic optimization yields outstanding photocatalytic performance, achieving CO production rates of 22.38 and 3.02 mmol g⁻¹ h⁻¹ under pure and 10% CO₂, respectively, surpassing most porphyrin-based photocatalysts.
