We report a facile chemical method to synthesize hybrid nanocomposites containing carbon nano-onions (CNOs) and zinc oxide or hydroxide. The structure, surface morphology, optical properties and surface area of the CNOs were characterized by X-ray diffraction, scanning electron microscopy with energy dispersive spectroscopy, transmission electron microscopy, thermogravimetric analysis, infrared and Raman spectroscopies, and adsorption/desorption N 2 techniques. For the first time, we demonstrate the fabrication of bulk heterojunction organic solar cell devices utilizing hybrid nanocomposites containing CNOs and ZnO as the electron transport layer. This configuration showed good photovoltaic performance with maximum external quantum efficiencies of 16.5 and 48.9% and power conversion efficiencies of 0.42 and 1.49% for the pristine ZnO and CNO/ ZnO (m CNO : m ZnO = 1 : 4) layers, respectively.[a] Dr.

“…For ZB, GB, and ZGB composites, most of the characteristic peaks in the spectra were similar to OB except for some small differences. In the case of ZB, the stretching vibrations n the ZB spectra at 1603 cm −1 represented the intramolecular hydrogen bonds, and the peak at around 865 cm −1 was related to metal oxide bonding, which further indicated the existence of ZnO [27]. In ZGB plot, the peak positioned at 1730 cm −1 showed the C=O stretching vibration of GO or hemicellulose, as both of them has the characteristic peaks of carbonyls and ester groups [28].…”

Bamboo materials with improved antibacterial performance based on ZnO and graphene oxide (GO) were fabricated by vacuum impregnation and hydrothermal strategies. The Zn2+ ions and GO nanosheets were firstly infiltrated into the bamboo structure, followed by dehydration and crystallization upon hydrothermal treatment, leading to the formation of ZnO/GO nanocomposites anchored in the bulk bamboo. The bamboo composites were characterized by several techniques including scanning electron microscopy (SEM), Fourier transform infrared spectra (FTIR), and X-ray diffraction (XRD), which confirmed the existence of GO and ZnO in the composites. Antibacterial performances of bamboo samples were evaluated by the bacteriostatic circle method. The introduction of ZnO/GO nanocomposites into bamboo yielded ZnO/GO/bamboo materials which exhibited significant antibacterial activity against Escherichia coli (E. coli, Gram-negative) and Bacillus subtilis (B. subtilis, Gram-positive) bacteria and high thermal stability. The antimicrobial bamboo would be expected to be a promising material for the application in the furniture, decoration, and construction industry.

“…For instance, cotton fibres functionalised with ZnO and carbon nanotube nanocomposites at a level of 22% by weight increased the UV protection factor (UPF) of cotton from 6 to 40. 399 Treatments used in these studies have not been scaled up to allow assessment of their production in commercial processes. Also, their economic feasibility needs to be studied before they can be recommended for potential large-scale use.…”

Environmental effects of ozone depletion and its interactions with climate change: Progress report, 2016

The Parties to the Montreal Protocol are informed by three Panels of experts. One of these is the Environmental Effects Assessment Panel (EEAP), which deals with two focal issues. The first focus is the effects of UV radiation on human health, animals, plants, biogeochemistry, air quality, and materials. The second focus is on interactions between UV radiation and global climate change and how these may affect humans and the environment. When considering the effects of climate change, it has become clear that processes resulting in changes in stratospheric ozone are more complex than previously believed. As a result of this, human health and environmental issues will be longer-lasting and more regionally variable. Like the other Panels, the EEAP produces a detailed report every four years; the most recent was published as a series of seven papers in 2015 (Photochem. Photobiol. Sci., 2015, 14, 1-184). In the years in between, the EEAP produces less detailed and shorter Progress Reports of the relevant scientific findings. The most recent of these was for 2015 (Photochem. Photobiol. Sci., 2016, 15, 141-147). The present Progress Report for 2016 assesses some of the highlights and new insights with regard to the interactive nature of the direct and indirect effects of UV radiation, atmospheric processes, and climate change. The more detailed Quadrennial Assessment will be made available in 2018.
