Energy harvesting from clothing.

Seeking new energy sources, especially those with less environmental impact, has been a consistent effort in the field of energy harvesting. In this work, we present an innovative energy harvesting technique for collecting energy from clothing. In this convenient but powerful method, electrical energy is generated by simply sliding a zein film assembly on the surface of clothes by constructing zein/cloth direct current (DC) triboelectric nanogenerators (TENGs).

High-performance triboelectric nanogenerators based on the organic semiconductor copper phthalocyanine.

In this work, we fabricated triboelectric nanogenerators (TENGs) with the triboelectric friction layer made of the organic semiconductor copper phthalocyanine (CuPc). Iodine was incorporated into CuPc to tune the work function of the CuPc films. With 10 wt% iodine doping concentration, the TENG showed an excellent output performance with a voltage output of 300 V, a current density of 110 mA m, and a power density of 8.

Identification of two novel anti-fibrotic benzopyran compounds produced by engineered strains derived from Streptomyces xiamenensis M1-94P that originated from deep-sea sediments.

The benzopyran compound obtained by cultivating a mangrove-derived strain, Streptomyces xiamenensis strain 318, shows multiple biological effects, including anti-fibrotic and anti-hypertrophic scar properties. To increase the diversity in the structures of the available benzopyrans, by means of biosynthesis, the strain was screened for spontaneous rifampicin resistance (Rif), and a mutated rpsL gene to confer streptomycin resistance (Str), was introduced into the S. xiamenensis strain M1-94P that originated from deep-sea sediments.
