Engineered Mesenchymal Stem Cell–NK Cell Complexes for Spatially Targeted and Functionally Revitalized Cancer Immunotherapy

Advanced Science, EarlyView.
IL‐15‐engineered stem cell–NK cell complexes, assembled via bioorthogonal chemistry, enable effective lung cancer immunotherapy. Abstract Natural killer (NK) cells represent a powerful immunotherapeutic strategy due to their intrinsic cytotoxicity and ability to target tumor cells independently of antigen presentation.

Review and classification of fretting fatigue test rigs [PDF]

, 2011
There is no standard or generally accepted test rig for fretting fatigue experiments. Therefore, researchers adopt an existing concept, or build a new test rig that meets their specific requirements.

N, S Co‐Doped Carbon Quantum Dots‐Riboflavin Composite Photosensitizers for Enhanced Iontophoresis‐Assisted Corneal Cross‐Linking

Advanced Science, EarlyView.
This study explores the use of N, S co‐doped carbon quantum dots (NS‐CQDs) as carriers for riboflavin, creating NS‐CQDs‐RF composite photosensitizers. These composites improve riboflavin absorption, enhance ROS generation efficiency, and preserve corneal epithelium integrity.

Visualization of Endosomal Escape of Intracellularly Delivered Protein With Unexpected Photochemical Internalization of Trypan Blue

Advanced Science, EarlyView.
TB, a conventional cell viability dye, acts as both a fluorescence modulator (quenching GFP fluorescence upon protein binding and recovering it upon release) and a photosensitizer that triggers endosomal escape via photochemical internalization (PCI) under 590 nm light.

Comparative study on fretting wear damage mechanisms of 316L steel in dry air and liquid lead-bismuth eutectic environments

Journal of Materials Research and Technology
Due to flow induced vibration caused by coolant circulation, fretting wear inevitably occurs between fuel cladding, heat exchanger tubes and their holders in Gen IV lead-bismuth eutectic (LBE) cooled nuclear reactors.
