Abstract: Ultrafast and ultrahigh temperature light sources are critical for advancements in energy, display, and security. However, their practical applications are hindered by limitations in oxidation resistance. Here, we address ...

Abstract: A diffusion absorption heat transformer (AHT) is very potential to improve energy utilization efficiency and reduce carbon emission, because it can be totally driven by waste heat without electricity consumption. On the ...

Abstract: HFO-1336mzz-Z with low global warming potential (GWP) was considered as a promising alternative of HCFC-123, HFC-245fa in air conditioning (AC) and heat pump (HP), respectively. In order to understand the operation ...

Abstract: Considering the issues of environmental pollution and energy efficiency, heat pumps are gradually replacing traditional coal combustion for heating at low ambient temperatures. In this paper, eco-friendly CO2/HCs with large ...

Abstract: With the gradual increase in the number of shield tunnels, the construction risks caused by segment floating have become increasingly prominent. Although many construction measures have been proposed to control segment ...

Abstract: Residual stress is easily generated in laser additive manufacturing (LAM) alloys due to high-temperature gradient during preparing, which increases the failure risk of materials. A LAM Hastelloy C22 was prepared by rotating ...
