Concrete floor slab flatness and levelness are parameters often specified in construction documents that contractors must meet to ensure a high quality of construction. However, the measurement of these parameters is cumbersome and time-consuming.
Free-standing, thin films were fabricated with a binder resulting in nearly an order of magnitude thickness decrease while increasing porosity and activation energy. These effects of such diminished significantly. Free-standing films could be fabricated with a binder.
This technology creates a light and metalless current collector for battery application. Cathodes coated on this new current collector demonstrated similar contact resistance, lower charge transfer resistance and similar or high rate performance.
Making existing buildings more airtight is critical in reducing the nation's energy consumption and carbon output. Most current methods of locating building leakage sites are disruptive to occupants and none of the methods can measure the flow of individual leakage sites.
Building Science Advisor is a web-based tool that allows users to quickly and reliably evaluate the moisture durability of their building wall designs and select the most energy-efficient and moisture-safe design.
Technologies for optimizing prefab retrofit panel installation using a real-time evaluator is described.
This solid-state thermal switch can significantly increase the functions of the thermal mass in buildings by actively controlling the thermal resistivity of insulation layers to optimize the energy storage and utilization to shed, shift, and shape HVAC loads on demand.
