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.

Scientists developed a machine-learning tool that can teach itself, with minimal external guidance, to differentiate between aerial images of flowering and nonflowering grasses — an advance that will greatly increase the pace of agricultural field research, they say. The work was conducted using images of thousands of varieties of Miscanthus grasses, each of which has its own flowering traits and timing.

An international team led by researchers from Empa and EPFL has explored how in future aerial robots could process construction materials precisely in the air – an approach with great potential for difficult-to-access locations or work at great heights. The flying robots are not intended to replace existing systems on the ground, but rather to complement them in a targeted manner for repairs or in disaster areas, for instance.

 

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.

A research team from Helmholtz Munich, the Technical University of Munich (TUM) and the TUM University Hospital has developed DeepNeo, an AI-powered algorithm that automates the process of analyzing coronary stents after implantation. The tool matches medical expert accuracy while significantly reducing assessment time. With strong validation in both human and animal models, DeepNeo has the potential to standardize monitoring after stent implantation and thus improve cardiovascular treatment outcomes.

Cationic Ir（III） complex bound to synthetic saponite was used as a donor for TTA-UC（Triplet-triplet annihilation up-conversion）with 9,10-diphenylanthracne.

High quantum yield of TTA-UC was attained due to the hybridization with organically modified synthetic saponite in R-limonene.

Since R-limonene is a natural product belonging to a green solvent, the present finding may promise the possible utility of clay minerals for TTA-UC in green solvents.
