Abstract: By using the low-loss element design method, a wideband high-efficiency transmitarray antenna with the linear-to-circular-polarization transformation is presented. The element is composed of ...

The recent growth can be attributed to factors such as increased demand for high-efficiency boilers and significant growth in power generation. The market also benefited from the expansion of ...

Compared to the cost of a new high-efficiency boiler, lots of things are relatively cheap. While it would be nice to sell a new boiler, there are easier and less expensive ways to reduce hydronic ...

Impressively, their catalyst operates at 90% energy efficiency, 100% product selectivity, and sustains its performance over an unprecedented 2,000 hours, far surpassing existing technologies.
