In this paper, a flexible luminous fabric device was developed and investigated for wearable three-dimensionally fitted low-level light therapy. The fabric device exhibited excellent optical and thermal properties. Its optical power density and operating temperature were stable during usage for 10 hours. In vitro experiments demonstrated a significant increase in collagen production in human fibroblast irradiated by the fabric device, compared with the fibroblast without light irradiation. A series of tests were conducted for the safety of the fabric for human skin contact according to ISO standard ISO 10993-1:2003. The results showed that there was no potential hazard when the luminous fabrics were in direct contact with human skin. (C) 2013 Optical Society of America

Enhanced electromechanical resilience and mechanism of the composites-coated fabric sensors with crack-induced conductive network for wearable applications

Xi Wang, Qiao Li, Xiaoming Tao

Summary: This study fabricated a strain sensor based on conductive composites-coated fabric and improved its performance through a physical pretreatment scheme. Results showed that the cracked surface morphology significantly reduced electrical hysteresis and improved electromechanical resilience. It was also found that the linear strain-resistance property of the sensors was largely retained after pretreatment. The findings suggest that cracking can be considered to improve the sensing performance of other coated fabric flexible sensors.

Novel oxymagnesite/green rust nanohybrids for selective removal and slow release of phosphate in water

Xiaoming Tao, Jiang Xu, Kun Yang, Daohui Lin

Summary: The new paradigm in wastewater treatment focuses on resource recovery, especially for non-renewable phosphorus (P). Nanomaterial-based adsorption technology, such as oxymagnesite/green rust (OMGR) nanohybrids, offers high efficiency and selectivity for P recovery from wastewater. OMGR demonstrated excellent selectivity for phosphate removal, wide pH adaptability, and a high removal capacity of 141 mg P.g-1. Phosphate-loaded OMGR also acted as a slow-release P-fertilizer, providing a green and eco-friendly approach to P resource recovery and reuse.

Evaluating and Modeling the Degradation of PLA/PHB Fabrics in Marine Water

Qi Bao, Ziheng Zhang, Heng Luo, Xiaoming Tao

Summary: The degradability of fabrics made from PLA/PHB blends in marine seawater was studied, and it was found that the dry-mass percentage of the fabrics decreased progressively after eight weeks of immersion. Environmental aging parameters, such as UV irradiation and aerating, were confirmed to accelerate the abiotic hydrolysis of the fabrics. The hydrolysis degradability of bulky PLA/PHB blends used to produce the fabrics was found to be negligible.
