Herein, we report a multifunctional chemoenzymatic nanoreactor (NanoNOx) for the glucose-controlled regeneration of natural and artificial nicotinamide cofactors. NanoNOx are built glucose oxidase-polymer hybrids that assemble in presence an organometallic catalyst: hemin. The design hybrid is optimized to increase effectiveness directional channeling at low substrate concentration. Importantly...

Exploring efficient and low-cost multifunctional electrocatalysts is a prerequisite for the development of energy storage converting technology. In this work, NiO/Co 2 P nanosheets (NiO/Co NSs) with heterogeneous structure were investigated through hydrothermal method, annealing phosphating processes. Considering synergistic effect between NiO Co P, we demonstrated excellent electrocatalytic pr...

Abstract A versatile use of a sulfur self‐doped biochar derived from Camellia japonica (camellia) flowers is demonstrated as multifunctional catalyst for overall water splitting and supercapacitor. The native content in the camellia flower facilitates situ self‐doping sulfur, which highly activates camellia‐driven (SA‐Came) with enhanced electron‐transfer ability long‐term durability. For split...

Abstract The aim of this study was to develop a novel multifunctional nanoparticle, which encapsulates SPION and Gemcitabine in PLGA±PEG to form multifunctional drug delivery system. For this aim, super paramagnetic iron oxide nanoparticles (SPIONs) were synthesized and encapsulated simultaneously with Gemcitabine (Gem) in PLGA±PEG copolymers via W/O/W double emulsification me...

Assumptions of individual rationality and preference stability provide the foundation for a convenient and tractable modeling approach. While both of these assumptions have come under scrutiny in distinct literatures, the two lines of research remain disjointed. This study begins by explicitly linking the two literatures while providing insights into perhaps the central issue facing behavioral ...
