Secondary alkaline Zn batteries are cost-effective, safe, and energy-dense devices, but they limited in rechargeability. Their short cycle life is caused by the transition between metallic ZnO, whose differences electronic conductivity, chemical reactivity, morphology undermine uniform electrochemical reactions electrode structural stability. To circumvent these issues, here we propose an design with bi-continuous zinc nanoporous structures capable of stabilizing ZnO. In particular, via situ...
A zero-gap flow cell was designed for the first electro-oxidative rearrangement of tetrahydro-β-carbolines to spirooxindoles with high yield, faradaic efficiency and productivity when LiBr discovered as a bi-functional mediator catalyst.
This study explores the optical design of a daytime radiative cooler with near-ideal solar reflectance and longwave infrared (LWIR) emittance through materials selection nanostructuring. Focusing on polymers as platform, we introduce bilayer architecture, comprising porous poly(vinylidene fluoride-co-hexafluoropropene) (P(VdF-HFP)) topcoat that serves low-index LWIR emissive effective medium, over nanofibrous, scattering polytetrafluoroethene underlayer. novel configuration yields superwhite...
A spheroidal microlens array is patterned on infrared transparent substrates to control the polar transmission and reflection of broadband thermal radiation. Geometric parameters materials can be altered tune angular transmittance. Our design promising for controlling emissions radiative cooling applications.
Ionic transports in nanopores hold the key to unlocking full potential of bi-continuous nanoporous (NP) metals as advanced electrodes electrochemical devices. The precise control uniform NP metal structures also provides us a unique opportunity understand how complex determine at nanoscales. For Au from dealloying Ag-Au alloy, we can tune pore size range 13 nm 2.4 microns and porosity between 38% 69% via isothermal coarsening. Ag reduction-induced decomposition AgCl, additionally its...
Oxidative rearrangement of tetrahydro-β-carbolines (THβCs) is one the most widely used reactions for synthesis biologically active spirooxindoles (natural products and drug molecules). While enzymatic chemical oxidation methods have been well established this transformation, corresponding electrochemical approach remain unknown. Herein, we reported first oxidative THβCs in a zero-gap flow cell. Under optimal condition, reaction can afford desired with up to 97% yield at Faradaic efficiency...
