Ultrasmall Bi/BiO nanoparticles as biocompatible and efficient CT imaging contrast agents.

Computed tomography (CT) imaging is a widely used diagnostic tool, but conventional iodine-based contrast agents suffer from limitations such as short circulation time and potential nephrotoxicity. In this study, we present a simple one-pot thermal decomposition method for synthesizing ultrasmall Bi/BiO nanoparticles (NPs) using a commercial Bi(NO) precursor and a surfactant mixture of oleic acid and oleylamine. Oleylamine acts as a reducing agent, facilitating the conversion of Bi to metallic Bi, while the BiO oxide layer is controlled by adjusting the oleic acid-to-oleylamine ratio.

Arteries are finely tuned thermosensors regulating myogenic tone and blood flow.

In response to changing blood pressure, arteries adjust their caliber to control blood flow. This vital autoregulatory property, termed vascular myogenic tone, stabilizes downstream capillary pressure. Here, we reveal that tissue temperature, combined with intraluminal pressure, critically determines myogenic tone.

Adaptive neural observer-based output feedback anti-actuator fault control of a nonlinear electro-hydraulic system with full state constraints.

This paper proposes an adaptive output feedback full state constrain (FSC) controller based on the adaptive neural disturbance observer (ANDO) for a nonlinear electro-hydraulic system (NEHS) with unmodeled dynamics. The Barrier Lyapunov Functions (BLFs) are utilized to ensure that all states of the system are specified within the constraints, and the approximation ability of radial basis function neural networks (RBFNNs) is used to cope with the unknown nonlinear functions. An adaptive neural compensation disturbance observer is elaborated to estimate the compound disturbance and oil leakage fault, effectively addressing these negative effects.
