“…Researchers have never stopped looking for the materials with natural friendly and excellent properties. Many environmentally friendly materials are proposed such as graphene and its oxide, [ 5 ] agro‐based material, [ 6 ] and the environmental‐friendly alloys. [ 7 ] However, these materials are often expensive, difficult to manufacture and preserve, or inflexible.…”

Flexible self‐power triboelectric nanogenerators (TENGs) have attracted worldwide attention in the fields of optoelectronic systems, communication, and biomedical diagnostics due to its outstanding energy collection capacity and high output potential. Wood, as a natural and environmental friendly material with excellent mechanical properties, is an ideal material for construction of high performance TENG. Herein, a porous wood based flexible triboelectric sensor (PWFTS) as a wearable motion testing system with ultralarge folding curvature and extreme high stability for real‐time body motion monitoring is presented. With an over 180° curving angle, the output power of the PWFTS from porous wood is more than 200% compared with that from natural wood. Moreover, a rapid degradation of as low as 48 h with extremely reliable repeatability and stability leads to an ideal candidate for wearable devices. The enhancement of such PWFTS may open up opportunities in innovative applications in various triboelectric devices and flexible integrated systems.

“…Chitosan in crab shell waste has the advantage of low cost and high bio-compatibility (Menkiti et al, 2008). It has recently been recommended to be utilized for industrial effluent treatment, heavy metal sorption and drinking water treatment (Vishali et al, 2016). The use of crab shell chitosan in wastewater treatment has not received adequate attention especially in developing countries for treatment of waste water, there are scarce literatures on this also online, few studies on this however include the work of Devi et al (2012), Okey-Onyesolu et al (2018b, Rahmi et al (2017) and Xu et al (2019).…”

Abattoir wastewater generated from various meat processing operations in several developing countries pose a serious threat to the environment. Consequently, there is urgent need to reduce the impact of environmental pollution from it. Coagulation techniques have been recommended and used by many researchers successfully in treating wastewater, therefore an investigation of possible use of chito-protein extracted from crab shell (locally sourced) was used as a coagulant for treating abattoir wastewater. Coagulation experiments were carried out using jar-test procedure to investigate the influence of pH, time of settling, temperature and adsorbent dosage for coagulation of BOD, COD, Turbidity and Colour from the wastewater sample. To determine the interaction effect of the various process variables, Response Surface Method (RSM) was used in the optimization of the process variables. To determine the effectiveness of the coagulant, pre and post characterization of the wastewater samples were undertaken, the result of the post characterization of the wastewater sample indicated that most of the water quality parameters except Iron were within WHO standard. The Total Suspended Solid (TSS), for instance stood at 564.6 mg/L and 29 mg/L respectively for pre and post characterisation, the value of 29 mg/L of the post characterization was below the WHO recommended value of 30 mg/L. The predicted responses and the experimental values correlated significantly, an indicator that RSM optimization method used in this study is suitable in modelling the process variables. The result of the study further shows that optimum process variable is dependent on the solution pH (acidic), coagulant dosage of 2–3g, settling time of 25–30 min and operating temperature from 323K to 333K. The coagulant used in this study, when compared with previous studies have shown to have strong potential for use as a coagulant and as an alternative to chemical coagulants in the treatment of abattoir wastewater.
