研究実績の概要

The investigated objectives were stretched to the field of hydrogels. We synthesized an ultrahigh surface area hierarchically porous carbon materials, prepared by potassium carbonate activation of polyacrylamide-hydroxy propyl cellulose hydrogel at high temperatures (500-900 °C) and explored their energy storage performances. The carbon material obtained has an ultrahigh surface area of 3387.2 m2 g-1 and a large pore volume of 1.963 cm3 g-1. The material showed an excellent supercapacitance performance (545.5 F g-1 at 1 A g-1 current density) with superior rate capability and an outstanding cycling stability of 96.3% after 5000 charge-discharge cycles. The electrochemical properties indicate that hierarchically porous carbons obtained from hydrogels are promising materials for high-performance supercapacitor applications.

Furthermore, we have used the kinetic schemes developed in 2022 (Scientific Reports, 2022, 12:17369, 1-15) to study the kinetics of the ubiquinone-rhodol (Q-Rh) fluorescence probe. The Q-Rh probe was used to monitor the activation of nicotinamide adenine (NADPH) within HeLa cancer cells. This activation can be further promoted (enhanced) by Ir(III)-complex (i.e. [(η5-C5Me5)Ir(phen)(H2O)]2+). The activation of NADPH with simultaneous monitoring of this process can exploit unique chemical reactions within cells. This concept stands in contrast to the conventional, widely recognized concept of biorthogonal chemistry. We have coined the term “bioparallel chemistry” to differentiate this approach.
