HOF-Enabled Synthesis of Porous PEDOT as an Improved Electrode Material for Supercapacitor.

Controlling the nanostructure of conducting polymers (CPs) is essential for enhancing their performance in energy storage applications. Existing CPs often suffer from low effective pseudocapacitance due to poor ion permeability. In this study, we introduce a novel approach using hydrogen-bonded organic frameworks (HOFs) to synthesize porous poly(3,4-ethylenedioxythiophene) (PEDOT).

Improved Liver Intravital Microscopic Imaging Using a Film-Assisted Stabilization Method.

Intravital microscopy (IVM) is a valuable method for biomedical characterization of dynamic processes, which has been applied to many fields such as neuroscience, oncology, and immunology. During IVM, vibration suppression is a major challenge due to the inevitable respiration and heartbeat from live animals. In this study, taking liver IVM as an example, we have unraveled the vibration inhibition effect of liquid bridges by studying the friction characteristics of a moist surface on the mouse liver.

Immobilization of Fe-Doped NiP Particles Within Biomass Agarose-Derived Porous N,P-Carbon Nanosheets for Efficient Bifunctional Oxygen Electrocatalysis.

A feasible and green sol-gel method is proposed to fabricate well-distributed nano-particulate Fe-NiP incorporated in N, P-codoped porous carbon nanosheets (Fe-NiP@N,P-CNSs) using biomass agarose as a carbon source, and ethylenediamine tetra (methylenephosphonic acid) (EDTMPA) as both the N and P source. The doped Fe in NiP is essential for a substantial increase in intrinsic catalytic activity, while the combined N,P-containing porous carbon matrix with a better degree of graphitization endows the prepared Fe-NiP@N,P-CNSs catalyst with a high specific surface area and improved electrical conductivity. Benefiting from the specific chemical composition and designed active site structure, the as-synthesized Fe-NiP@N,P-CNSs manifests a satisfying catalytic performance toward both oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in an alkaline solution, with low overpotential, small Tafel slope and long-term durability, relative to the counterparts (Fe-free NiP/NiPO@N,P-CNSs and CNSs) with single components and even comparable to Pt/C and RuO catalysts.
