Converting Pomelo Peel into Eco-friendly and Low-Consumption Photothermic Biomass Sponge toward Multifunctioal Solar-to-Heat Conversion

ACS Sustainable Chemistry & Engineering (2020)

Chang Zhang Peng Xiao Feng Ni Luke Yan Qingquan Liu

Converting waste into versatile materials has been considered as an effective strategy to tackle environmental issues such as shortages in food, clean water, and energy. Conventional carbonization technology has provided an effective approach for constructing photothermal materials for interfacial evaporation or crude oil removal. However, high energy consumption, poor shape retention, and weak mechanical strength have significantly hindered the practical application of conventional carbonization technology. This work discusses how a biomass-derived sponge from discarded pomelo peel (PP) may be used to collect photothermal polypyrrole in a cost-effective way with mild reaction. The photothermic sponge which is derived from this process, can then be effectively employed to realize solar enhanced water evaporation and heavy crude oil removal. The polypyrrole-functionalized pomelo peel (FPyPP) can be attained by a mild, one-pot wet oxypolymerization method, resulting in over 95% absorption of sunlight and evaporation rates of about 1.22 kg/m2 under the sun. Furthermore, the concentrated heat on the sponge surface can efficiently reduce the viscosity of heavy crude oil and thereby lead to an effective cleanup. This study aims to provide a low-cost, low-energy-consumption, and eco-friendly approach to the acquisition of the multifunctional photothermic sponge by recycling the waste and demonstrating potential applications in tackling clean water generation and polluted water treatment.

Dually Decorated Na₃V₂(PO₄)₂F₃ by Carbon and 3D Graphene as Cathode Material for Sodium‐Ion Batteries with High Energy and Power Densities

ChemElectroChem (2020)

Lizhen Hu Siqi Cheng Shunhua Xiao Wenna Li Zhuo Chen

Abstract The dually decorated Na 3 V 2 (PO 4 ) 2 F 3 by in‐situ formed carbon and three‐dimensional graphene (NVPF/C@3DG) is prepared via two hydrothermal steps and a high‐temperature calcination. Benefiting from the high electronic conductivity of carbon and 3DG, high surface area and the resulted high diffusion coefficients of Na + , NVPF/C@3DG displays superior electrochemical performance to the control NVPF/C. Between 2.5 and 4.5 V (vs. Na + /Na), NVPF/C@3DG presents the initial discharge capacity of 123.6 mAh g −1 at 0.2 C (25.6 mA g −1 ) and capacity retention of 92.1 % after 60 cycles, while NVPF/C shows initial discharge capacity of 119 mAh g −1 and capacity retention of 84.1 % under the identical test conditions. Even at 15 C, the initial discharge capacity and capacity retention after 1000 cycles of NVPF/C@3DG are as high as 91.2 mAh g −1 and 82.9 %, respectively, much better than the initial discharge capacity of 71.2 mAh g −1 and the corresponding capacity retention of 76.4 % for NVPF/C, respectively.

Biological AssessmentIn-Vivoof Gel-HA Scaffold Materials Containing Nano-Bioactive Glass for Tissue Engineering

Journal of Macromolecular Science Part A (2014)

Zhihua Zhou Liujiao Xiang Baoli Ou Tianlong Huang Hu Zhou

AbstractTo evaluate the biological safety of the composite materials based on gelatin (Gel), hyaluronic acid (HA), and nano-bioactive glass (NBG), which has a potential application in tissue engineering, the in-vivo biological properties were investigated by hemolysis behavior, micronucleus, skin irritation and acute toxicity test. Scanning electron microscopy (SEM) morphology demonstrated that the Gel-HA/NBG composite scaffolds had interconnected pores with mean diameters of 50–500 μm. The hemolysis test suggested that the Gel-HA/NBG composite scaffold, with a hemolysis ratio of 1.11%, showed no obvious hemolysis reaction. The micronucleus frequency of the Gel-HA/NBG was (3.1 ± 0.52) %; this indicated that it shows no genotoxic effect. The skin irritation result showed no systemic signs of toxicity in the integrity skin of the animals. The Gel-HA/NBG scaffolds showed no acute systemic toxicity and the liver, heart, lung, and kidney samples also showed no remarkable change in the morphology. Therefore, Gel-HA/NBG composite scaffold would be a suitable candidate of biomedical materials for tissue engineering.Keywords: Gelatinhyaluronic acidnano-bioactive glasscomposite scaffoldin-vivo biological properties

Fabrication and Characterization of Gelatin/Chitosan Microspheres for Drug Release

Journal of Macromolecular Science Part B (2011)

Zhihua Zhou Jianan Zhou Lihua Liu Qingfeng Yi Qingquan Liu

Gelatin/chitosan (Gel/Cs) microspheres were fabricated through an emulsification-solvent evaporation technique using saturated glutaraldehyde as a cross-linking reagent. The influences of the concentration of the emulsifier, stirring speed, and water/oil ratio on particle size and surface morphology were investigated. The experimental results indicated that the particle size of the microspheres decreased with increasing concentration of the emulsifier; however, the microsphere size did not change when the concentration of the emulsifier exceeded 0.016 g·mL−1. The particle diameter of the microspheres decreased with increasing stirring speed and increased with increasing water/oil ratio. The concentration of an acetone/water solution had an obvious effect on the morphologies of the Gel/Cs microspheres during the course of dehydration; the surface of the microspheres became smooth when dehydrated by an acetone solution with a volume ratio of 3:1.
