| 1 | Biodegradable, Super-Strong, and Conductive Cellulose Macrofibers for Fabric-Based Triboelectric Nanogenerator显示文摘Electronic fibers used to fabricate wearable triboelectric nanogenerator(TENG) for harvesting human mechanical energy have been extensively explored. However, little attention is paid to their mutual advantages of environmental friendliness, mechanical properties, and stability. Here, we report a super-strong, biodegradable, and washable cellulose-based conductive macrofibers, which is prepared by wet-stretching and wet-twisting bacterial cellulose hydrogel incorporated with carbon nanotubes and polypyrrole. The cellulose-based conductive macrofibers possess high tensile strength of 449 MPa(able to lift 2 kg weights), good electrical conductivity(~ 5.32 S cm^(-1)), and excellent stability(Tensile strength and conductivity only decrease by 6.7% and 8.1% after immersing in water for 1 day). The degradation experiment demonstrates macrofibers can be degraded within 108 h in the cellulase solution. The designed fabric-based TENG from the cellulose-base conductive macrofibers shows a maximum open-circuit voltage of 170 V, short-circuit current of 0.8 μA, and output power at 352 μW, which is capable of powering the commercial electronics by charging the capacitors. More importantly, the fabric-based TENGs can be attached to the human body and work as self-powered sensors to effectively monitor human motions. This study suggests the potential of biodegradable, super-strong, and washable conductive cellulose-based fiber for designing eco-friendly fabric-based TENG for energy harvesting and biomechanical monitoring. | Sanming Hu Jing Han Zhijun Shi Kun Chen Nuo Xu Yifei Wang Ruizhu Zheng Yongzhen Tao Qijun Sun Zhong Lin Wang Guang Yang | 2022 | Nano-Micro Letters2022，14，7： | 2 |

| 6 | Bacterial cellulose/glycolic acid/glycerol composite membrane as a system to deliver glycolic acid for anti-aging treatment显示文摘Glycolic acid(GA),as an anti-aging skincare ingredient,plays a pivotal role in anti-aging treatment.However,its benefits could be overshadowed due to its side effects including skin burning and irritation when overused.Bacterial cellulose(BC)is a highly pure form of cellulose,biosynthesized in the form of a swollen membrane by several kinds of bacteria that was demonstrated to modulate the release of model drugs owing to its porous and 3D fibrous network structure,and glycerol(GL),as a plasticizer,could enhance the controlled drug delivery.Herein,we report a topical controlled drug delivery system based on BC membrane,GA and GL for controlling sustainable release of GA to reduce its side effects on the skin,while maintaining its prolonged and maximum therapeutic effect.The results showed that the incorporation of GL increased the malleability and flexibility of BC/GA/GL membrane,as compared with BC/GA membrane.In addition,the GL enhanced the control of the GA delivery,as evidenced by a higher swelling capacity and thereby a slower release of the GA from BC/GA/GL membrane.More importantly,in vitro study indicated that both BC/GA and BC/GA/GL membranes could effectively stimulate endogenous collagen synthesis in NIH3T3 cells owing to the release of GA,and that BC/GA/GL membrane is more conducive to a long-term cell adhesion,spreading,and proliferation of NIH3T3 and HaCaT cells due to its lower and sustainable release of GA than BC/GA membrane.This study suggests the BC/GL/GA composite membrane holds great promise as an appealing platform to control the release of GA to greatly promote renewal of skin cells for effective anti-aging treatment. | Bricard Mbituyimana Lin Mao Sanming Hu Muhammad Wajid Ullah Kun Chen Lina Fu Weiwei Zhao Zhijun Shi Guang Yang | 2021 | Journal of Bioresources and Bioproducts2021，6，2： | 0 |
