A team of engineering and chemical researchers from the University of Sydney has been investigating a new technology for capturing water from moist air. The technology is inspired by the clever use of surface structuring on the back of a beetle native to the Namib Desert in southern Africa ...
根据第二段Consequently,current DAC plants are expensive to operate,with the cost of pulling a tonne of CO2 from the air amounting to hundreds of US dollars(因此,目前的DAC工厂运营成本高昂,从空气中提取一吨二氧化碳的成本高达数百美元),可知目前DAC工厂的一个主要问题是它们不具有成本效益,成...

When the air that is rich in fog is zapped with a beam of electrically charged particles, known as ions, water droplets in it become electrically charged and thus can be drawn toward a mesh of wires, similar to a window screen, placed in their path. The droplets then collect on that me...
The nitrogen is removed from the air through a cryogenic air separation unit (ASU) or with the use of membranes. Combustion thus takes place with nearly pure oxygen. The final result is a flue gas containing mainly CO2 and water. The CO2 is purified by removing water ...
The rising negative effects of climate change are caused mainly by the increase of atmospheric carbon dioxide concentrations, calling for advanced technologies to extract carbon dioxide from atmospheric air. Here we review carbon dioxide capture from atmospheric air by amine-functionalized silica composites...
Water spray characteristics, including droplet size and velocity, airborne dust capture potential, and induced airflow quantity for various spray nozzle designs were evaluated to provide basic information for improving spray applications. Water droplet size and velocity characteristics were initially measured...
1, the size of the cover body (tuyere size) the air volume of the cap cover body and tuyere size difference will cause a large measurement error, so it is necessary to use the tuyere size similar to the cover body for measurement. According to the size and area of the tuyere to be ...
Emission trajectories produced by integrated assessment models increasingly suggest that gigatonnes of carbon removal will be required to stabilize atmospheric greenhouse gas concentrations at safe levels. This can be accomplished using the direct air ca
根据文章第一段“Researchers have designed a hand-held device that can capture and change water molecules from the air into drinkable water using only surrounding sunlight as its energy source. (研究人员设计了一种手持设备,可以捕获空气中的水分子,并将其转化为可饮用的水,仅使用周围的阳光作为能量来源...
