The chemiluminescence reaction between luminol and reductant was investigated by a flow-injection system. The results show that this reaction can be used for the determination of the reductant which is active to chemiluminescence in alkaline lumminol, and of the substance which can, in appropriate manner, be converted into the active reductant. The mechanism of the chemiluminescence reaction may be that the reductant reduces dissolved oxygen to O2 , then O2 reacts with alkaline luminol to generate chemiluminescence.

Anterior urethral strictures, where the length is more kthan 2 cm, are best treated by substitution urethroplasty with either preputial/penile skin flaps or free grafts.1 The use of dartos pedicled flaps has many advantages in terms of increased survival thanks to its own vascularization. Recently, buccal mucosa has become increasingly popular among urologists for urethral replacement when local penile skin is unavailable. Both penile skin flaps and buccal mucosa grafts have emerged as reliable urethral substitutes with comparable long-term results. These urethral substitutes are traditionally placed on the ventral aspect of the stricture and have a success rate of about 85%.

Convertible hydrogel supercapacitors have emerged as promising energy storage devices in switches,diodes, and transistors. However, inherent weaknesses in ionic conductivity, mechanical properties,and water retention of hydrogel electrolytes seriously hinder their development. Inspired by the hardness conversion of sea cucumber skin, a conductivity and mechanics dual-tunable salt gel electrolyte is successfully designed. The salt gel presents a reversible switching of conductors-insulators and a mechanical regulation between softness and hardness via the dissolution-crystallization transition of sodium acetate trihydrate（SAT）. Meanwhile, the salt gels spontaneously grow a layer of “armor” through saturated phase-change salt crystals effectively reducing water evaporation of hydrogel ***, this phase-change soft-rigid conversion strategy will expand the capabilities of gel-based flexible supercapacitors(area capacitance: 258.6 mF cm-2), and the capacitance retention rate could still reach 86.9% after 3000 cycles at high temperatures. Moreover, the salt gel supercapacitor is potentially used in over-heat alarm systems. It is anticipated that the strategy of conductivity and mechanics of dual-tunable salt gel would provide a new perspective on the development of energy storage devices,wearable electronics, and flexible robots.
