In this work, zinc oxide (ZnO) and titanium dioxide (TiO 2 ) nanostructures were grown on different cellulose paper substrates, namely, Whatman, office, and commercial hospital papers, using a hydrothermal method assisted by microwave irradiation. Pure ZnO and TiO 2 nanostructures were synthesized; however, the growth of TiO 2 above ZnO was also investigated to produce a uniform heterostructure. Continuous ZnO nanorod arrays were grown on Whatman and hospital papers; however, on office paper, the formation of nanoplates originating nanoflower structures could be observed. TiO 2 nanoparticles homogeneously covered all the substrates, in some conditions forming uniform TiO 2 films. Structural characterization was carried out by scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and Raman spectroscopy. The optical characterization of all the materials was carried out. The produced materials were investigated for multifunctional applications, like photocatalyst agents, bacterial inactivators, and ultraviolet (UV) sensors. To evaluate the photocatalytic activity under UV and solar radiations, rhodamine B was the model-test contaminant indicator and the best photocatalytic activity was achieved with Whatman paper. Hospital paper with TiO 2 nanoparticles showed significant antibacterial properties against Staphylococcus aureus. ZnO-based UV sensors demonstrated a responsivity of 0.61 μA W -1 .

“…28 For that purpose, nano-sized ZnO is an ideal metal oxide as it is biocompatible while it also shows photocatalytic and antibacterial activity. [29][30] Indeed, as e.g. industrial waste water is often polluted with organic dyes, it is highly desired to degrade these refractory organics 31 .…”

Ambient particulate matter (PM) pollution has posed serious threats to global environment and public health. However, high efficient filtration of submicron particles, so named 'secondary pollution' caused by e.g. bacterial growth in filters and the use of non-degradable filter materials, remains a serious challenge. In this study, Polyvinyl alcohol (PVA) and konjac glucomannan (KGM) based nanofiber membranes, loaded with ZnO nanoparticles, were prepared through green electrospinning and eco-friendly thermal crosslinking. Thus obtained fibrous membranes do not only show high-efficient air-filtration performance but also show superior photocatalytic activity and antibacterial activity. The filtration efficiency of the ZnO@PVA/KGM membranes for ultrafine particles (300nm) were higher than 99.99%, being superior to commercial HEPA filters. By virtue of the high photocatalytic activity, the Methyl orange (MO) were efficiently decolorized with a removal efficiency of more than 98% at an initial concentration of 20 mgL-1 under 120 min solar irradiation. The multifunctional membrane with high removal efficiency, low flow resistance, superior photocatalytic activity and antibacterial activity was successfully achieved. It's conceivable that the combination of biodegradable polymer and active metal particle would form

“…The reason for improvement in the antimicrobial functionality is referred to the interaction of the negatively charged cell walls of the pathogens with the positively charged cationic sites of the antimicrobial agent, which in turn change its physical and chemical properties causing the interruption of the cell membrane functions and protein activity, as well as the inability to multiply. Silver nanoparticles release the silver ions producing higher biocidal effect on the microorganisms [3].…”

“…Therefore, it is an excellent substrate for dyeing and printing as well as for imparting high performance with additional functionalities. Typical examples of such functionalities are antimicrobial activity, softness, easy-care, flame retardancy, and water &oil repellency [1][2][3]. To achieve this task, traditional wet methods were used for applying coloration and finishes, however they require large amounts of chemicals, water and energy.…”

T HIS RESEARCH aims to utilize microwave energy and nanotechnology to improve the printability and performance of cotton prints via screen printing technique. Each cotton sample was individually pre-treated by microwave power ranged from 300 to 700 watts and for a period ranged from 1 to 9 min. Afterwards the optimum sample was printed by printing paste containing Remazol™ reactive dye and silver nanoparticles (Ag-NPs) with different concentrations. The printed samples were fixed using microwave energy then were subjected to steaming or thermo-fixation. The obtained results clarified that, the prints obtained using microwave and Ag-NPs were found to have better color strength, fastness properties, antibacterial behavior and surface morphology when they were compared to the conventional techniques using thermo-fixation and steaming.
