Abstract Both plants and animals possess analogous tissues containing hierarchical networks of pores, with pore size ratios that have evolved to maximize mass transport rates reactions. The underlying physical principles this optimized design are embodied in Murray’s law. However, we yet realize the benefit mimicking nature’s Murray synthetic materials due challenges fabricating vascularized structures. Here emulate optimum natural systems following law using a bottom-up approach. Such...
Nitric oxide (NO) has been well identified as a specific free radical molecule possessing wide-ranging therapeutic effects. Targeted delivery and controlled release of NO are highly desired to realize precision gas therapy, but still challenging owing the non-targetability uncontrollability itself. Herein, we propose new concept MRI-guided ultrasound-triggered for therapy. Based on this concept, develop novel ultrasound-responsive BNN-type NO-releasing (NORM) an advanced rattle-type...
Magnetic and ferroelectric properties are investigated for the polycrystalline Bi2Fe4O9 ceramics with different grain sizes (60–2000 nm) synthesized by a modified Pechini method. It shows that magnetic strongly dependent on size. For 60 nm samples, magnetization curves exhibit superimposed behavior of antiferromagnetic (AFM) ferromagnetic (FM) component. As size increases, FM component is suppressed AFM interaction becomes dominant. Simultaneously, Néel temperature (TN) shifts to high...
