Bringing aromas indoors with the help of chemical products — yes, air fresheners, wax melts, floor cleaners, deodorants and others — rapidly fills the air with nanoscale particles that are small enough to get deep into your lungs, Purdue engineers have found over a series of studies.

In a paper published in National Science Review, an international team of scientists report a coordination nanomedicine (ZnDHT NM) featuring cascade specific Fe³⁺ capturing and in situ catalysis for achieving tumor catalysis-enhanced differentiation therapy. This nanomedicine can simultaneously treat cancer stem-like cells (CSCs) and bulk tumor cells by interfering with tumor Fe metabolism and redox homeostasis, thereby effectively inhibiting tumor growth, recurrence and metastasis.

In a paper published in National Science Review, an international team of scientists discovered a universal N₂O emission baseline that could guide the sustainable management of riverine N₂O. The discovery of EF-lines emphasized the importance of targeting hotspots and managing baseline emissions sustainably to balance social and environmental benefits. The priority control of organic and NH₄⁺ pollution could rapidly eliminate global riverine N₂O hotspots and reduce emissions by half. However, the further restoration of baseline emissions on nitrate removal is a long-term challenge.

A research team led by Professor JIANG Changlong from the Institute of Solid State Physics, the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has successfully developed an innovative multi-scenario real-time fluorescence detection technology to tackle this problem. The team designed and fabricated a sensor by embedding upconversion optical probes into three-dimensional porous hydrogels. This sensor, integrated with the color recognition functionality of a smartphone, allows rapid and on-site detection of methylglyoxal. 

We are using up nickel at an alarming rate to make stainless steel. Thankfully, researchers have found a way to cut nickel out of the equation, without compromising on strength.

Recently, the work was completed by the group of Prof. Sheng Meng from the Institute of Physics, Chinese Academy of Sciences, and Beijing National Research Center for Condensed Matter Physics. By using the non-adiabatic time-dependent density functional molecular dynamics method, independently developed by the group software (TDAP), they studied the ultrafast melting process in insulator magnesium oxide (MgO) materials, confirming that longer-wavelength laser-induced tunnel ionization is an important reason for accelerating ultrafast melting in wide-bandgap insulator materials, which provides the universal microscopic mechanism explanations for the laser-induced phase transitions.

Research team led by Tao Zhang introduces CCB-RR, an innovative model for recommending code reviewers in open-source projects, achieving 87% accuracy in Top-10 recommendations and significantly outperforming baselines with a context-centric approach.
