Abstract The development of neuromorphic optoelectronic systems opens up the possibility next generation artificial vision. In this work, novel broadband (from 365 to 940 nm) and multilevel storage synaptic thin‐film transistor (TFT) arrays are reported using photosensitive conjugated polymer (poly[(9,9‐dioctylfluorenyl‐2,7‐diyl)‐co‐(bithiophene)], F8T2) sorted semiconducting single‐walled carbon nanotubes (sc‐SWCNTs) as channel materials. responses inherited absorption from both F8T2...

Abstract Intracellular oxidative amplification can effectively destroy tumor cells. Additionally, Fe‐mediated Fenton reaction often converts cytoplasm H 2 O to generate extensive hypertoxic hydroxyl radical ( • OH), leading irreversible mitochondrion damage for celleradication, which is widely famous as chemodynamic therapy (CDT). Unfortunately, intracellular overexpressed glutathione (GSH) always efficiently scavenges OH, resulting in the significantly reduced CDT effect. To overcome this...

Intraosseous ultrasound imaging is valuable for guiding pedicle screw placement in surgery. However, single-frequency ultrasound, whether low or high, often fails to provide both adequate resolution and depth simultaneously. To address this limitation, we introduce a novel ultrafast multi-frequency patch fusion method navigation. This approach combines the strengths of high-frequency low-frequency images, greatly enhancing detail clarity resulting images while significantly reducing time...

Highly dispersed gold nanoparticles (NPs) incorporated mesoporous titania thin films with ultrahigh Au content (53.3 wt%) were synthesized by a deposition-precipitation method using urea as precipitator, which showed high off-resonant third-order optical nonlinear susceptibility (χ(3) = 2.69 × 10−8 esu) measured the Z-scan technique at 1064 nm. The enhanced χ(3) value of materials was attributed to homogeneous dispersion and concentration NPs, linear refractive index matrix.
