Advanced Functional Materials, EarlyView.Dynamic linkages are highly attractive in preparing single crystals of covalent organic polymers (COPs). Here, single crystals of two COPs CityU‐15 and CityU‐16 based on reversible B─N bonds are constructed using tetra(4‐pyridyl)tetrathiafulvalene and tetra(4‐pyridyl)porphine as monomers.

Magnetic Resonance Imaging of Brain Function
, 2004 Publisher Summary This chapter describes the magnetic resonance imaging (MRI) of the brain function. The rapid development of methods for noninvasive brain mapping has led to exciting advances in understanding of the human brain. Functional MRI relies on detecting the small changes in image brightness on MRI scans, associated with the hemodynamic ...

Overview of Functional Magnetic Resonance Imaging [PDF]
Neurosurgery Clinics of North America, 2011 Blood Oxygen Level Dependent (BOLD) functional magnetic resonance imaging (fMRI) depicts changes in deoxyhemoglobin concentration consequent to task-induced or spontaneous modulation of neural metabolism. Since its inception in 1990, this method has been widely employed in thousands of studies of cognition for clinical applications such as surgical ...

Advanced Functional Materials, EarlyView.Transarterial Chemoembolization (TACE) may aggravate liver fibrosis. In this study, a novel oral targeting nanoemulsion is fabricated to enhance the therapeutic effect of antifibrotic drug‐pirfenidone (PFD) on fibrosis after TACE. Studies have shown that PFD nanoemulsion can enhance the oral liver targeting effect of PFD, and effectively improve the ...

Direct Ink Writing of Conductive Hydrogels
Advanced Functional Materials, EarlyView.This review examines the use of direct ink writing (DIW) for fabricating conductive hydrogels with customizable 3D structures. It outlines the rheological requirements for successful DIW, followed by an exploration of the materials and ink formulations used to impart electronic and/or ionic conductivity to hydrogels while maintaining printability ...
