Feasibility assessment of a remote krypton sampling system for emergency applications
Nuclear Engineering and TechnologyRadioactive krypton (85Kr) is a chemically inert fission product that serves as an important tracer for nuclear activities. Conventional monitoring systems require manual liquid nitrogen (LN2) replenishment, limiting their use in remote sites and ...

Sputter investigations of carbon and molybdenum using low energy krypton ions [PDF]
AIP AdvancesThe lifetime of gridded ion engines for space propulsion is critically limited by the grid erosion rate. With the current trend from xenon toward krypton as propellant, sputter yields of krypton ions impinging on typical grid materials are required. Here,

Advanced Science, EarlyView.Stable radicals are attractive for photonic and quantum information technologies but are often limited by instability. We stabilize intrinsic radicals in graphene quantum dots via 2D polymerization of perylene derivatives, where bilayer defect confinement suppresses quenching (100–500 K).

Advanced Science, EarlyView.Butterfly wing–inspired intrinsically self‐healing polymer interlayers enable flexible perovskite optoelectronics with high luminance, strain‐insensitive stability, and environmental resilience. These hierarchically structured films redistribute mechanical stress, suppress defect formation, and maintain performance under repeated bending, paving the ...

Advanced Science, EarlyView.Androgenetic alopecia (AGA) is a common form of hair loss with limited treatment options. Silencing of WNT5A signaling, which is widely known as the trigger of the ncWNT signaling pathway, happens in hair follicle stem cells from balding areas. It leads to downregulation of ATF3 and its target FOSB.

Nature, 1898 PROF. RUNGE, in your last issue, points out that the wave length of the bright green line of krypton is 5570˙4 (Rowland's scale), while that of the auroral line is about 5571. In the paper presented to the Royal Society by Dr. Travers and myself on June 3, the wave-length is given as 55677. The wave-length was re-measured by Mr. Baly on June 7, and its

Advanced Science, EarlyView.Controlled Pt–Pt fine structure in square‐planar Pt(II) complexes governs metal–metal‐to‐ligand charge‐transfer (MMLCT) state formation, exciton dynamics, and organic light‐emitting diode performance. Short Pt–Pt contacts in Pt(fppz)2 enable coherent metal–metal coupling, sub‐microsecond emission and an external quantum efficiency of 29%, whereas ...
