The aim of this research was to probe the potential application of nano-titanium dioxide (TiO2)/basic magnesium hypochlorite (BMH)-containing linear low-density polyethylene (LLDPE) composite film in grape fresh-keeping. Mechanical properties, transparency, barrier performance and antibacterial activity of the nano-composite membrane were measured, and results showed that the antibacterial zone diameter of TiO2/BMH on pathogen-Aspergillus niger was 31.4 mm, with mixing ratio of BMH/TiO2 to 2:1. It was clearly shown that the synthesized nano-composite films decreased mechanical properties and transparency of the membrane, and also had a significant impact on sensory score, mass loss rate, decay rate, ascorbic acid (Vc) content and titratable acid content compared with LLDPE films. Moreover, the results revealed that the LLDPE antibacterial film can be effectively used for storing grapes, preserving the flavor of grapes and had an obviously effect in prolonging grapes’ shelf life.

One of the growing concerns in the construction industry is energy consumption and energy efficiency in residential buildings. Moreover, management of non-degradable solid glass wastes is becoming a critical issue worldwide. Accordingly, incorporation of recycled expanded glass aggregates (EGA) as a substitution for natural fine aggregate in cement composites would be a sustainable solution in terms of energy consumption in the buildings and waste management. This experimental research aims to investigate the effects of EGA on fresh and hardened properties and thermal insulating performance of cement mortar. To enhance the mechanical properties and water resistance of the EGA-mortar, nano titanium dioxide (nTiO2) was used as nanofillers. The results showed an increase in workability and water absorption of the EGA-mortar. In addition, a significant decrease in bulk density and compressive strength observed by incorporating EGA into the cement mortar. The EGA-mortar exhibited a low heat transfer rate and excellent thermal insulation property. Furthermore, inclusion of nTiO2 increased compressive strength and water resistance of EGA-mortar, however, their heat transfer rate was increased. The results demonstrated that EGA-mortar can be integrated into the building envelop or non-load bearing elements such as wall partition as a thermal resistance to reduce the energy consumption in residential buildings.

The article explored the finishing process of cotton fabric with nano titanium dioxide and adopted the dipping-rolling-drying process for the purpose of cotton fabric with good ultraviolet (UV) resistant performance. In this study, the concentration of titanium dioxide acted as variable factor to test and analysis the regular pattern of fabric UV resistant performance, mechanical properties and wearability after being treated with different concentrations of titanium dioxide solution. The results showed that the property of UV resistance improved with the increase of solution concentration. The ultraviolet protection factors (UPF) of fabric was 43.5 at a concentration of 0.5%, which was beyond the UV resistant standard of 40. However, the mechanical properties and wearability decreased in varying degrees with the increase in concentration of titanium dioxide. Thus the overall performance should be considered comprehensively to select the finishing process. All of these conclusions provide basic data for some in-depth research in the future.
