Clean, inexpensive water is the 21st century's greatest challenge. Population increase, climate change, and water quality degradation make it difficult to meet global water demand. Integrated water management requires technological innovation. Nanotechnology can increase water and wastewater treatment efficiency and supply by safely using unconventional water sources. Nanotechnology for water and wastewater treatment has advanced recently.

Utilizing building energy modelling and simulation can lead to more cost-effective and energy-efficient building envelope solutions than conducting field tests of actual implementations. This study focused on the building envelope's key components, including fenestration, shading devices, wall and roof assembly, and building configuration. A base-case model for the Tropical climate was created, adjusted, and then used in a parametric simulation, where 11 building envelope parameters were adjusted individually.

When highways and railroads traverse rural residential areas, site vibrations induced by impact hole formation construction lead to frequent accidents in residential housing and related construction works. The primary objective of this study is to propose a new method for assessing the extent of construction impacts on residential houses for analyzing the vibration response of a non-uniform unsaturated soil site during heavy hammer percussion for hole formation, which was validated in field tests on the Wudu to Jiuzhaigou section of the G8513 highway.
